  • Create a Social Community of Trust Along With Your Federal Digital Services Governance

    - by TedMcLaughlan
    The Digital Services Governance Recommendations were recently released, supporting the US Federal Government's Digital Government Strategy Milestone Action #4.2 to establish agency-wide governance structures for developing and delivering digital services. Figure 1 - From: "Digital Services Governance Recommendations" While extremely important from a policy and procedure perspective within an Agency's information management and communications enterprise, these recommendations only very lightly reference perhaps the most important success enabler - the "Trusted Community" required for ultimate usefulness of the services delivered. By "ultimate usefulness", I mean the collection of public, transparent properties around government information and digital services that include social trust and validation, social reach, expert respect, and comparative, standard measures of relative value. In other words, do the digital services meet expectations of the public, social media ecosystem (people AND machines)? A rigid governance framework, controlling by rules, policies and roles the creation and dissemination of digital services may meet the expectations of direct end-users and most stakeholders - including the agency information stewards and security officers. All others who may share comments about the services, write about them, swap or review extracts, repackage, visualize or otherwise repurpose the output for use in entirely unanticipated, social ways - these "stakeholders" will not be governed, but may observe guidance generated by a "Trusted Community". As recognized members of the trusted community, these stakeholders may ultimately define the right scope and detail of governance that all other users might observe, promoting and refining the usefulness of the government product as the social ecosystem expects. So, as part of an agency-centric governance framework, it's advised that a flexible governance model be created for stewarding a "Community of Trust" around the digital services. The first steps follow the approach outlined in the Recommendations: Step 1: Gather a Core Team In addition to the roles and responsibilities described, perhaps a set of characteristics and responsibilities can be developed for the "Trusted Community Steward/Advocate" - i.e. a person or team who (a) are entirely cognizant of and respected within the external social media communities, and (b) are trusted both within the agency and outside as practical, responsible, non-partisan communicators of useful information. The may seem like a standard Agency PR/Outreach team role - but often an agency or stakeholder subject matter expert with a public, active social persona works even better. Step 2: Assess What You Have In addition to existing, agency or stakeholder decision-making bodies and assets, it's important to take a PR/Marketing view of the social ecosystem. How visible are the services across the social channels utilized by current or desired constituents of your agency? What's the online reputation of your agency and perhaps the service(s)? Is Search Engine Optimization (SEO) a facet of external communications/publishing lifecycles? Who are the public champions, instigators, value-adders for the digital services, or perhaps just influential "communicators" (i.e. with no stake in the game)? You're essentially assessing your market and social presence, and identifying the actors (including your own agency employees) in the existing community of trust. Step 3: Determine What You Want The evolving Community of Trust will most readily absorb, support and provide feedback regarding "Core Principles" (Element B of the "six essential elements of a digital services governance structure") shared by your Agency, and obviously play a large, though probably very unstructured part in Element D "Stakeholder Input and Participation". Plan for this, and seek input from the social media community with respect to performance metrics - these should be geared around the outcome and growth of the trusted communities actions. How big and active is this community? What's the influential reach of this community with respect to particular messaging or campaigns generated by the Agency? What's the referral rate TO your digital services, FROM channels owned or operated by members of this community? (this requires governance with respect to content generation inclusive of "markers" or "tags"). At this point, while your Agency proceeds with steps 4 ("Build/Validate the Governance Structure") and 5 ("Share, Review, Upgrade"), the Community of Trust might as well just get going, and start adding value and usefulness to the existing conversations, existing data services - loosely though directionally-stewarded by your trusted advocate(s). Why is this an "Enterprise Architecture" topic? Because it's increasingly apparent that a Public Service "Enterprise" is not wholly contained within Agency facilities, firewalls and job titles - it's also manifested in actual, perceived or representative forms outside the walls, on the social Internet. An Agency's EA model and resulting investments both facilitate and are impacted by the "Social Enterprise". At Oracle, we're very active both within our Enterprise and outside, helping foster social architectures that enable truly useful public services, digital or otherwise.

  • Profit's COLLABORATE 10 Session Selections

    - by Aaron Lazenby
    COLLABORATE 2010 is a mere 11 days away (thanks for the reminder @ocp_advisor). Every year I publish my a list of the sessions I think reflect some of the more interesting people/trends in enterprise IT. I should be at all of these sessions, so drop by for a chat--I'll be the guy tapping out emails on my iPad... Monday, April 19 9:15 a.m. - Keynote: Transforming Customer Value, Delivering Highest Customer Service Location: Keynote Hall I never miss Charles Phillips when he speaks--it's one of the best opportunities to get an update on Oracle product developments and strategy. And there's certainly occasion for an update: this will be Phillips' first big presentation since the Oracle + Sun Strategy Update in late January. Phillips is appearing with Oracle Executive Vice President of Development Thomas Kurian which means there should be some excellent information about how customers are using Oracle's complete software and hardware stack to address enterprise IT challenges. The session should provide some excellent context for the rest of the week's session...don't miss it. 10:45 a.m. - Oracle Fusion Applications: Functional Overview Location: South Seas FI met Basheer Khan at COLLABORATE 08 in Denver and have followed his work ever since. He's a former member of the OAUG Board of Directors, an Oracle ACE, and a charismatic enterprise IT expert. Having worked with the Oracle Usability Advisory Board, Basheer should have some fascinating insights to share about the features and interface of Oracle's Fusine Applications. This session, along with Nadia Bendjedou's "10 Things You Can Do Today to Prepare for the Next Generation Applications" (on Tuesday, April 20 8:00 a.m. in room 3662) should give attendees the update they need about Oracle's next-generation applications.   1:15p.m. - E-Business Suite in the Amazon Cloud Location: South Seas HI did my first full-fledged cloud computing coverage at last year's COLLABORATE show (check out my interview with Oracle's Bill Hodak), where I first learned about Amazon's EC2 offering. I've since talked with several people who have provisioned server space on Amazon's cloud with great results. So I'm looking forward to watching the audience configure an instance of the Oracle E-Business Suite release 12 on the cloud while Chuck Edwards from Blue Gecko drives. This session should take some of the mist and vapor out of the cloud conversation.2:30 p.m. - "Zero Sign-on" to EBS - Enabling 96000 Users to Login to EBS Without User Maintenance Location: South Seas HI'll be sitting tight in South Seas H for the next session on Monday where Doug Pepka, a ten-year veteran of communications giant Comcast, will be walking attendees through a massive single sign-on (SSO) project across the enterprise. I'm working on a story about SSO for the August issue of Profit, so this session has real practical value to me. Plus the proliferation of user account logins--both personal and professional--makes this a critical usability/change management issue for IT leaders planning for successful long-term IT implementations.   Tuesday 8:00 am  - Information Architecture for Men in Kilts Location: SURF AGetting to a 8:00 a.m. presentation is a tall order in Las Vegas, but presenter Billy Cripe will make it worth your effort. Not only is the title of this session great, but the content should appeal to any IT strategist looking to push the limits of Web 2.0 technologies in the enterprise. Cripe is a product management director of Enterprise 2.0 and Enterprise Content Management at Oracle, author of Reshaping Your Business with Web 2.0, and a prolific blogger--he knows how information architecture is critical to and enterprise 2.0 implementation.    10:30a.m. - Oracle Virtualization: From Desktop to Data Center Location: REEF FData center virtualization is still one of the best ways to reduce the cost of running enterprise IT. With the addition of Sun products, Oracle has the industry's most comprehensive virtualization portfolio. I must admit, I'm no expert in this subject. So I'm looking forward to Monica Kumar's presentation so I can get up to speed.   Wednesday 8:00 a.m. - The Art of the Steal Location: Mandalay Bay Ballroom JMany will know Frank Abagnale from Steven Spielberg's 2002 film "Catch Me if You Can." The one-time con man and international fugitive who swindled $2.5 million in forged checks went on to help U.S. federal officials investigate fraud cases. Now the CEO of Abagnale and Associates, he has become an invaluable source to the business world on the subject of fraud and fraud protection. With identity theft and digital fraud still on the rise, this session should be an entertaining, and sobering, education on the threats facing businesses and customers around the world. A great way to start Wednesday.1:00 p.m. - Google Wave: Will it replace e-mail as we know it today? Location: SURF EBy many assessments (my own included), Google Wave is a bit of an open collaboration failure. It may seem like an odd reason for me to be excited about this session, but I'm looking forward to the chance to revisit the technology. Also, this is a great case study in connecting free, available Internet tools to existing enterprise computing environments--an issue that IT strategists must contend with as workers spreads out and choose their own productivity tools.

  • Supporting users if they're not on your site

    - by Roger Hart
    Have a look at this Read Write Web article, specifically the paragraph in bold and the comments. Have a wry chuckle, or maybe weep for the future of humanity - your call. Then pause, and worry about information architecture. The short story: Read Write Web bumps up the Google rankings for "Facebook login" at the same time as Facebook makes UI changes, and a few hundred users get confused and leave comments on Read Write Web complaining about not being able to log in to their Facebook accounts.* Blindly clicking the first Google result is not a navigation behaviour I'd anticipated for folks visiting big names sites like Facebook. But then, I use Launchy and don't know where any of my files are, depend on Firefox auto-complete, view Facebook through my IM client, and don't need a map to find my backside with both hands. Not all our users behave in the same way, which means not all of our architecture is within our control, and people can get to your content in all sorts of ways. Even if the Read Write Web episode is a prank of some kind (there are, after all, plenty of folks who enjoy orchestrated trolling) it's still a useful reminder. Your users may take paths through and to your content you cannot control, and they are unlikely to deconstruct their assumptions along the way. I guess the meaningful question is: can you still support those users? If they get to you from Google instead of your front door, does what they find still make sense? Does your information architecture still work if your guests come in through the bathroom window? Ok, so here they broke into the house next door - you can't be expected to deal with that. But the rest is well worth thinking about. Other off-site interaction It's rarely going to be as funny as the comments at Read Write Web, but your users are going to do, say, and read things they think of as being about you and your products, in places you don't control. That's good. If you pay attention to it, you get data. Your users get a better experience. There are easy wins, too. Blogs, forums, social media &c. People may look for and find help with your product on blogs and forums, on Twitter, and what have you. They may learn about your brand in the same way. That's fine, it's an interaction you can be part of. It's time-consuming, certainly, but you have the option. You won't get a blogger to incorporate your site navigation just in case your users end up there, but you can be there when they do. Again, Anne Gentle, Gordon McLean and others have covered this in more depth than I could. Direct contact Sales people, customer care, support, they all talk to people. Are they sending links to your content? if so, which bits? Do they know about all of it? Do they have the content they need to support them - messaging that funnels sales, FAQ that are realistically frequent, detailed examples of things people want to do, that kind of thing. Are they sending links because users can't find the good stuff? Are they sending précis of your content, or re-writes, or brand new stuff? If so, does that mean your content isn't up to scratch, or that you've got content missing? Direct sales/care/support interactions are enormously valuable, and can help you know what content your users find useful. You can't have a table of contents or a "See also" in a phonecall, but your content strategy can support more interactions than browsing. *Passing observation about Facebook. For plenty if folks, it is  the internet. Its services are simple versions of what a lot of people use the internet for, and they're aggregated into one stop. Flickr, Vimeo, Wordpress, Twitter, LinkedIn, and all sorts of games, have Facebook doppelgangers that are not only friendlier to entry-level users, they're right there, behind only one layer of authentication. As such, it could own a lot of interaction convention. Heavy users may well not be tech-savvy, and be quite change averse. That doesn't make this episode not dumb, but I'm happy to go easy on 'em.

  • SQLAuthority News – #TechEdIn – TechEd India 2012 Memories and Photos

    - by pinaldave
    TechEd India 2012 was held in Bangalore last March 21 to 23, 2012. Just like every year, this event is bigger, grander and inspiring. Pinal Dave at TechEd India 2012 Family Event Every single year, TechEd is a special affair for my entire family.  Four months before the start of TechEd, I usually start to build the mental image of the event. I start to think  about various things. For the most part, what excites me most is presenting a session and meeting friends. Seriously, I start thinking about presenting my session 4 months earlier than the event!  I work on my presentation day and night. I want to make sure that what I present is accurate and that I have experienced it firsthand. My wife and my daughter also contribute to my efforts. For us, TechEd is a family event, and the two of them feel equally responsible as well. They give up their family time so I can bring out the best content for the Community. Pinal, Shaivi and Nupur at TechEd India 2012 Guinea Pigs (My Experiment Victims) I do not rehearse my session, ever. However, I test my demo almost every single day till the last moment that I have to present it already. I sometimes go over the demo more than 2-3 times a day even though the event is more than a month away. I have two “guinea pigs”: 1) Nupur Dave and 2) Vinod Kumar. When I am at home, I present my demos to my wife Nupur. At times I feel that people often backup their demo, but in my case, I have backup demo presenters. In the office during lunch time, I present the demos to Vinod. I am sure he can walk my demos easily with eyes closed. Pinal and Vinod at TechEd India 2012 My Sessions I’ve been determined to present my sessions in a real and practical manner. I prefer to present the subject that I myself would be eager to attend to and sit through if I were an audience. Just keeping that principle in mind, I have created two sessions this year. SQL Server Misconception and Resolution Pinal and Vinod at TechEd India 2012 We believe all kinds of stuff – that the earth is flat, or that the forbidden fruit is apple, or that the big bang theory explains the origin of the universe, and so many other things. Just like these, we have plenty of misconceptions in SQL Server as well. I have had this dream of co-presenting a session with Vinod Kumar for the past 3 years. I have been asking him every year if we could present a session together, but we never got it to work out, until this year came. Fortunately, we got a chance to stand on the same stage and present a single subject.  I believe that Vinod Kumar and I have an excellent synergy when we are working together. We know each other’s strengths and weakness. We know when the other person will speak and when he will keep quiet. The reason behind this synergy is that we have worked on 2 Video Learning Courses (SQL Server Indexes and SQL Server Questions and Answers) and authored 1 book (SQL Server Questions and Answers) together. Crowd Outside Session Hall This session was inspired from the “Laurel and Hardy” show so we performed a role-playing of those famous characters. We had an excellent time at the stage and, for sure, the audience had a wonderful time, too. We had an extremely large audience for this session and had a great time interacting with them. Speed Up! – Parallel Processes and Unparalleled Performance Pinal Dave at TechEd India 2012 I wanted to approach this session at level 400 and I was very determined to do so. The biggest challenge I had was that this was a total of 60 minutes of session and the audience profile was very generic. I had to present at level 100 as well at 400. I worked hard to tune up these demos. I wanted to make sure that my messages would land perfectly to the minds of the attendees, and when they walk out of the session, they could use the knowledge I shared on their servers. After the session, I felt an extreme satisfaction as I received lots of positive feedback at the event. At one point, so many people rushed towards me that I was a bit scared that the stage might break and someone would get injured. Fortunately, nothing like that happened and I was able to shake hands with everybody. Pinal Dave at TechEd India 2012 Crowd rushing to Pinal at TechEd India 2012 Networking This is one of the primary reasons many of us visit the annual TechEd event. I had a fantastic time meeting SQL Server enthusiasts. Well, it was a terrific time meeting old friends, user group members, MVPs and SQL Enthusiasts. I have taken many photographs with lots of people, but I have received a very few back. If you are reading this blog and have a photo of us at the event, would you please send it to me so I could keep it in my memory lane?

  • SQL SERVER – Columnstore Index and sys.dm_db_index_usage_stats

    - by pinaldave
    As you know I have been writing on Columnstore Index for quite a while. Recently my friend Vinod Kumar wrote about  SQL Server 2012: ColumnStore Characteristics. A fantastic read on the subject if you have yet not caught up on that subject. After the blog post I called him and asked what should I write next on this subject. He suggested that I should write on DMV script which I have prepared related to Columnstore when I was writing our SQL Server Questions and Answers book. When we were writing this book SQL Server 2012 CTP versions were available. I had written few scripts related to SQL Server columnstore Index. I like Vinod’s idea and I decided to write about DMV, which we did not cover in the book as SQL Server 2012 was not released yet. We did not want to talk about the product which was not yet released. The first script which I had written was with DMV - sys.column_store_index_stats. This DMV was displaying the statistics of the columnstore indexes. When I attempted to run it on SQL Server 2012 RTM it gave me error suggesting that this DMV does not exists. Here is the script which I ran: SELECT * FROM sys.column_store_index_stats; It generated following error: Msg 208, Level 16, State 1, Line 1 Invalid object name ‘column_store_index_stats’. I was pretty confident that this DMV was available when I had written the scripts. The next reaction was to type ‘sys.’ only in SSMS and wait for intelisense to popup DMV list. I scrolled down and noticed that above said DMV did not exists there as well. Now this is not bug or missing feature. This was indeed something can happen because the version which I was practicing was early CTP version. If you go to the page of the DMV here, it clearly stats notice on the top of the page. This documentation is for preview only, and is subject to change in later releases. Now this was not alarming but my next thought was if this DMV is not there where can I find the information which this DMV was providing. Well, while I was thinking about this, I noticed that my another friend Balmukund Lakhani was online on personal messenger. Well, Balmukund is “Know All” kid. I have yet to find situation where I have not got my answers from him. I immediately pinged him and asked the question regarding where can I find information of ‘column_store_index_stats’. His answer was very abrupt but enlightening for sure. Here is our conversation: Pinal: Where can I find information of column_store_index_stats? Balmukund: Assume you have never worked with CTP before and now try to find the information which you are trying to find. Honestly  it was fantastic response from him. I was confused as I have played extensively with CTP versions of SQL Server 2012. Now his response give me big hint. I should have not looked for DMV but rather should have focused on what I wanted to do. I wanted to retrieve the statistics related to the index. In SQL Server 2008/R2, I was able to retrieve the statistics of the index from the DMV - sys.dm_db_index_usage_stats. I used the same DMV on SQL Server 2012 and it did retrieved the necessary information for me. Here is the updated script which gave me all the necessary information I was looking for. Matter of the fact, if I have used my earlier SQL Server 2008 R2 script this would have just worked fine. SELECT DB_NAME(Database_ID) DBName, SCHEMA_NAME(schema_id) AS SchemaName, OBJECT_NAME(ius.OBJECT_ID) ObjName, i.type_desc, i.name, user_seeks, user_scans, user_lookups, user_updates,* FROM sys.dm_db_index_usage_stats ius INNER JOIN sys.indexes i ON i.index_id = ius.index_id AND ius.OBJECT_ID = i.OBJECT_ID INNER JOIN sys.tables t ON t.OBJECT_ID = i.OBJECT_ID GO Let us see the resultset of above query. You will notice that column Type_desc describes the type of the index. You can additionally write WHERE condition on the column and only retrieve only selected type of Index.

  • How to Answer a Stupid Interview Question the Right Way

    - by AjarnMark
    Have you ever been asked a stupid question during an interview; one that seemed to have no relation to the job responsibilities at all?  Tech people are often caught off-guard by these apparently irrelevant questions, but there is a way you can turn these to your favor.  Here is one idea. While chatting with a couple of folks between sessions at SQLSaturday 43 last weekend, one of them expressed frustration over a seemingly ridiculous and trivial question that she was asked during an interview, and she believes it cost her the job opportunity.  The question, as I remember it being described was, “What is the largest byte measurement?”.  The candidate made up a guess (“zetabyte”) during the interview, which is actually closer than she may have realized.  According to Wikipedia, there is a measurement known as zettabyte which is 10^21, and the largest one listed there is yottabyte at 10^24. My first reaction to this question was, “That’s just a hiring manager that doesn’t really know what they’re looking for in a candidate.  Furthermore, this tells me that this manager really does not understand how to build a team.”  In most companies, team interaction is more important than uber-knowledge.  I didn’t ask, but this could also be another geek on the team trying to establish their Alpha-Geek stature.  I suppose that there are a few, very few, companies that can build their businesses on hiring only the extreme alpha-geeks, but that certainly does not represent the majority of businesses in America. My friend who was there suggested that the appropriate response to this silly question would be, “And how does this apply to the work I will be doing?” Of course this is an understandable response when you’re frustrated because you know you can handle the technical aspects of the job, and it seems like the interviewer is just being silly.  But it is also a direct challenge, which may not be the best approach in interviewing.  I do have to admit, though, that there are those folks who just won’t respect you until you do challenge them, but again, I don’t think that is the majority. So after some thought, here is my suggestion: “Well, I know that there are petabytes and exabytes and things even larger than that, but I haven’t been keeping up on my list of Greek prefixes that have not yet been used, so I would have to look up the exact answer if you need it.  However, I have worked with databases as large as 30 Terabytes.  How big are the largest databases here at X Corporation?”  Perhaps with a follow-up of, “Typically, what I have seen in companies that have databases of your size, is that the three biggest challenges they face are: A, B, and C.  What would you say are the top 3 concerns that you would like the person you hire to be able to address?…Here is how I have dealt with those concerns in the past (or ‘Here is how I would tackle those issues for you…’).” Wait! What just happened?!  We took a seemingly irrelevant and frustrating question and turned it around into an opportunity to highlight our relevant skills and guide the conversation back in a direction more to our liking and benefit.  In more generic terms, here is what we did: Admit that you don’t know the specific answer off the top of your head, but can get it if it’s truly important to the company. Maybe for some reason it really is important to them. Mention something similar or related that you do know, reassuring them that you do have some knowledge in that subject area. Draw a parallel to your past work experience. Ask follow-up questions about the company’s specific needs and discuss how you can fulfill those. This type of thing requires practice and some forethought.  I didn’t come up with this answer until a day later, which is too late when you’re interviewing.  I still think it is silly for an interviewer to ask something like that, but at least this is one way to spin it to your advantage while you consider whether you really want to work for someone who would ask a thing like that.  Remember, interviewing is a two-way process.  You’re deciding whether you want to work there just as much as they are deciding whether they want you. There is always the possibility that this was a calculated maneuver on the part of the hiring manager just to see how quickly you think on your feet and how you handle stupid questions.  Maybe he knows something about the work environment and he’s trying to gauge whether you’ll actually fit in okay.  And if that’s the case, then the above response still works quite well.

  • Sea Monkey Sales & Marketing, and what does that have to do with ERP?

    - by user709270
    Tier One Defined By Lyle Ekdahl, Oracle JD Edwards Group Vice President and General Manager  I recently became aware of the latest Sea Monkey Sales & Marketing tactic. Wait now, what is Sea Monkey Sales & Marketing and what does that have to do with ERP? Well if you grew up in USA during the 50’s, 60’s and maybe a bit in the early 70’s there was a unifying media of culture known as the comic book. I was a big Iron Man fan. I always liked the troubled hero aspect of Tony Start and hey he was a technologist. This is going somewhere, just hold on. Of course comic books like most media contained advertisements. Ninety pound weakling transformed by Charles Atlas in just 15 minutes per day. Baby Ruth, Juicy Fruit Gum and all assortments of Hostess goodies were on display. The best ad was for the “Amazing Live Sea-Monkeys – The real live fun-pets you grow yourself!” These ads set the standard for exaggeration and half-truth; “…they love attention…so eager to please, they can even be trained…” The cartoon picture on the ad is of a family of royal looking sea creatures – daddy, mommy, son and little sis – sea monkey? There was a disclaimer at the bottom in fine print, “Caricatures shown not intended to depict Artemia.” Ok what ten years old knows what the heck artemia is? Well you grow up fast once you’ve been separated from your buck twenty five plus postage just to discover that it is brine shrimp. Really dumb brine shrimp that don’t take commands or do tricks. Unfortunately the technology industry is full of sea monkey sales and marketing. Yes believe it or not in some cases there is subterfuge and obfuscation used to secure contracts. Hey I get it; the picture on the box might not be the actual size. Make up what you want about your product, but here is what I don’t like, could you leave out the obvious falsity when it comes to my product, especially the negative stuff. So here is the latest one – “Oracle’s JD Edwards is NOT tier one”. Really? Definition please! Well a whole host of googleable and reputable sources confirm that a tier one vendor is large, well known, and enjoys national and international recognition. Let me see large, so thousands of customers? Oh and part of the world’s largest business software and hardware corporation? Check and check JD Edwards has that and that. Well known, enjoying national and international recognition? Oracle’s JD Edwards EnterpriseOne is available in 21 languages and is directly localized in 33 countries that support some of the world’s largest multinationals and many midsized domestic market companies. Something on the order of half the JD Edwards customer base is outside North America. My passport is on its third insert after 2 years and not from vacations. So if you don’t mind I am going to mark national and international recognition in the got it column. So what else is there? Well let me offer a few criteria. Longevity – The JD Edwards products benefit from 35+ years of intellectual property development; through booms, busts, mergers and acquisitions, we are still here Vision & innovation – JD Edwards is the first full suite ERP to run on the iPad as just one example Proven track record of execution – Since becoming part of Oracle, JD Edwards has released to the market over 20 deliverables including major release, point releases, new apps modules, tool releases, integrations…. Solid, focused functionality with a flexible, interoperable, extensible underlying architecture – JD Edwards offers solid core ERP with specialty modules for verticals all delivered on a well defined independent tools layer that helps enable you to scale your business without an ERP reimplementation A continuation plan – Oracle’s JD Edwards offers our customers a 6 year roadmap as well as interoperability with Oracle’s next generation of applications Oh I almost forgot that the expert sources agree on one additional thing, tier one may be a preferred vendor that offers product and services to you with appealing value. You should check out the TCO studies of JD Edwards. I think you will see what the thousands of customers that rely on these products to run their businesses enjoy – that is the tier one solution with the lowest TCO. Oh and if you get an offer to buy an ERP for no license charge, remember the picture on the box might not be the actual size.

  • ASSIMP in my program is much slower to import than ASSIMP view program

    - by Marco
    The problem is really simple: if I try to load with the function aiImportFileExWithProperties a big model in my software (around 200.000 vertices), it takes more than one minute. If I try to load the very same model with ASSIMP view, it takes 2 seconds. For this comparison, both my software and Assimp view are using the dll version of the library at 64 bit, compiled by myself (Assimp64.dll). This is the relevant piece of code in my software // default pp steps unsigned int ppsteps = aiProcess_CalcTangentSpace | // calculate tangents and bitangents if possible aiProcess_JoinIdenticalVertices | // join identical vertices/ optimize indexing aiProcess_ValidateDataStructure | // perform a full validation of the loader's output aiProcess_ImproveCacheLocality | // improve the cache locality of the output vertices aiProcess_RemoveRedundantMaterials | // remove redundant materials aiProcess_FindDegenerates | // remove degenerated polygons from the import aiProcess_FindInvalidData | // detect invalid model data, such as invalid normal vectors aiProcess_GenUVCoords | // convert spherical, cylindrical, box and planar mapping to proper UVs aiProcess_TransformUVCoords | // preprocess UV transformations (scaling, translation ...) aiProcess_FindInstances | // search for instanced meshes and remove them by references to one master aiProcess_LimitBoneWeights | // limit bone weights to 4 per vertex aiProcess_OptimizeMeshes | // join small meshes, if possible; aiProcess_SplitByBoneCount | // split meshes with too many bones. Necessary for our (limited) hardware skinning shader 0; cout << "Loading " << pFile << "... "; aiPropertyStore* props = aiCreatePropertyStore(); aiSetImportPropertyInteger(props,AI_CONFIG_IMPORT_TER_MAKE_UVS,1); aiSetImportPropertyFloat(props,AI_CONFIG_PP_GSN_MAX_SMOOTHING_ANGLE,80.f); aiSetImportPropertyInteger(props,AI_CONFIG_PP_SBP_REMOVE, aiPrimitiveType_LINE | aiPrimitiveType_POINT); aiSetImportPropertyInteger(props,AI_CONFIG_GLOB_MEASURE_TIME,1); //aiSetImportPropertyInteger(props,AI_CONFIG_PP_PTV_KEEP_HIERARCHY,1); // Call ASSIMPs C-API to load the file scene = (aiScene*)aiImportFileExWithProperties(pFile.c_str(), ppsteps | /* default pp steps */ aiProcess_GenSmoothNormals | // generate smooth normal vectors if not existing aiProcess_SplitLargeMeshes | // split large, unrenderable meshes into submeshes aiProcess_Triangulate | // triangulate polygons with more than 3 edges //aiProcess_ConvertToLeftHanded | // convert everything to D3D left handed space aiProcess_SortByPType | // make 'clean' meshes which consist of a single typ of primitives 0, NULL, props); aiReleasePropertyStore(props); if(!scene){ cout << aiGetErrorString() << endl; return 0; } this is the relevant piece of code in assimp view code // default pp steps unsigned int ppsteps = aiProcess_CalcTangentSpace | // calculate tangents and bitangents if possible aiProcess_JoinIdenticalVertices | // join identical vertices/ optimize indexing aiProcess_ValidateDataStructure | // perform a full validation of the loader's output aiProcess_ImproveCacheLocality | // improve the cache locality of the output vertices aiProcess_RemoveRedundantMaterials | // remove redundant materials aiProcess_FindDegenerates | // remove degenerated polygons from the import aiProcess_FindInvalidData | // detect invalid model data, such as invalid normal vectors aiProcess_GenUVCoords | // convert spherical, cylindrical, box and planar mapping to proper UVs aiProcess_TransformUVCoords | // preprocess UV transformations (scaling, translation ...) aiProcess_FindInstances | // search for instanced meshes and remove them by references to one master aiProcess_LimitBoneWeights | // limit bone weights to 4 per vertex aiProcess_OptimizeMeshes | // join small meshes, if possible; aiProcess_SplitByBoneCount | // split meshes with too many bones.

What could be the reason for such a difference in performance? The two software are using the same dll Assimp64.dll (compiled in my computer with vc++ 2010 express) and the same function aiImportFileExWithProperties to load the model, so I assume that the actual code employed is the same. How is it possible that the function aiImportFileExWithProperties is 100 times slower when called by my sotware than when called by assimp view? What am I missing? I am not good with dll, dynamic and static libraries so I might be missing something obvious. ------------------------------ UPDATE I found out the reason why the code is going slower. Basically I was running my software with "Start debugging" in VC++ 2010 Express. If I run the code outside VC++ 2010 I get same performance of assimp view. However now I have a new question. Why does the dll perform slower in VC++ debugging? I compiled it in release mode without debugging information. Is there any way to have the dll go fast in debugmode i.e. not debugging the dll? Because I am interested in debugging only my own code, not the dll that I assume is already working fine. I do not want to wait 2 minutes every time I want to load my software to debug. Does this request make sense?

  • Extending Blend for Visual Studio 2013

    - by Chris Skardon
    Originally posted on: http://geekswithblogs.net/cskardon/archive/2013/11/01/extending-blend-for-visual-studio-2013.aspxSo, I got a comment yesterday on my post about Extending Blend 4 and Blend for Visual Studio 2012 asking if I knew how to get it working for Blend for Visual Studio 2013.. My initial thoughts were, just change the location to get the blend dlls from Visual Studio 11.0 to 12.0 and you’re all set, so I went to do that, only to discover that the dlls I normally reference, well – they don’t exist. So… I’ve made a presumption that the actual process of using MEF etc is still the same. I was wrong. So, the route to discovery – required DotPeek and opening a few of blends dlls.. Browsing through the Blend install directory (./Microsoft Visual Studio 12.0/Blend/) I notice the .addin files: So I decide to peek into the SketchFlow dll, then promptly remember SketchFlow is quite a big thing, and hunting through there is not ideal, luckily there is another dll using an .addin file, ‘Microsoft.Expression.Importers.Host’, so we’ll go for that instead. We can see it’s still using the ‘IPackage’ formula, but where is that sucker? Well, we just press F12 on the ‘IPackage’ bit and DotPeek takes us there, with a very handy comment at the top: // Type: Microsoft.Expression.Framework.IPackage // Assembly: Microsoft.Expression.Framework, Version=12.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a // MVID: E092EA54-4941-463C-BD74-283FD36478E2 // Assembly location: C:\Program Files (x86)\Microsoft Visual Studio 12.0\Blend\Microsoft.Expression.Framework.dll Now we know where the IPackage interface is defined, so let’s just try writing a control. Last time I did a separate dll for the control, this time I’m not, but it still works if you want to do it that way. Let’s build a control! STEP 1 Create a new WPF application Naming doesn’t matter any more! I have gone with ‘Hello2013’ (see what I did there?) STEP 2 Delete: App.Config App.xaml MainWindow.xaml We won’t be needing them STEP 3 Change your application to be a Class Library instead. (You might also want to delete the ‘vshost’ stuff in your output directory now, as they only exist for hosting the WPF app, and just cause clutter) STEP 4 Add a reference to the ‘Microsoft.Expression.Framework.dll’ (which you can find in ‘C:\Program Files\Microsoft Visual Studio 12.0\Blend’ – that’s Program Files (x86) if you’re on an x64 machine!). STEP 5 Add a User Control, I’m going with ‘Hello2013Control’, and following from last time, it’s just a TextBlock in a Grid: <UserControl x:Class="Hello2013.Hello2013Control" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" mc:Ignorable="d" d:DesignHeight="300" d:DesignWidth="300"> <Grid> <TextBlock>Hello Blend for VS 2013</TextBlock> </Grid> </UserControl> STEP 6 Add a class to load the package – I’ve called it – yes you guessed – Hello2013Package, which will look like this: namespace Hello2013 { using Microsoft.Expression.Framework; using Microsoft.Expression.Framework.UserInterface; public class Hello2013Package : IPackage { private Hello2013Control _hello2013Control; private IWindowService _windowService; public void Load(IServices services) { _windowService = services.GetService<IWindowService>(); Initialize(); } private void Initialize() { _hello2013Control = new Hello2013Control(); if (_windowService.PaletteRegistry["HelloPanel"] == null) _windowService.RegisterPalette("HelloPanel", _hello2013Control, "Hello Window"); } public void Unload(){} } } You might note that compared to the 2012 version we’re no longer [Exporting(typeof(IPackage))]. The file you create in STEP 7 covers this for us. STEP 7 Add a new file called: ‘<PROJECT_OUTPUT_NAME>.addin’ – in reality you can call it anything and it’ll still read it in just fine, it’s just nicer if it all matches up, so I have ‘Hello2013.addin’. Content wise, we need to have: <?xml version="1.0" encoding="utf-8"?> <AddIn AssemblyFile="Hello2013.dll" /> obviously, replacing ‘Hello2013.dll’ with whatever your dll is called. STEP 8 We set the ‘addin’ file to be copied to the output directory: STEP 9 Build! STEP 10 Go to your output directory (./bin/debug) and copy the 3 files (Hello2013.dll, Hello2013.pdb, Hello2013.addin) and then paste into the ‘Addins’ folder in your Blend directory (C:\Program Files\Microsoft Visual Studio 12.0\Blend\Addins) STEP 11 Start Blend for Visual Studio 2013 STEP 12 Go to the ‘Window’ menu and select ‘Hello Window’ STEP 13 Marvel at your new control! Feel free to email me / comment with any problems!

  • Searching for the Perfect Developer&rsquo;s Laptop.

    - by mbcrump
    I have been in the market for a new computer for several months. I set out with a budget of around $1200. I knew up front that the machine would be used for developing applications and maybe some light gaming. I kept switching between buying a laptop or a desktop but the laptop won because: With a Laptop, I can carry it everywhere and with a desktop I can’t. I searched for about 2 weeks and narrowed it down to a list of must-have’s : i7 Processor (I wasn’t going to settle for an i5 or AMD. I wanted a true Quad-core machine, not 2 dual-core fused together). 15.6” monitor SSD 128GB or Larger. – It’s almost 2011 and I don’t want an old standard HDD in this machine. 8GB of DDR3 Ram. – The more the better, right? 1GB Video Card (Prefer NVidia) – I might want to play games with this. HDMI Port – Almost a standard on new Machines. This would be used when I am on the road and want to stream Netflix to the HDTV in the Hotel room. Webcam Built-in – This would be to video chat with the wife and kids if I am on the road. 6-Cell Battery. – I’ve read that an i7 in a laptop really kills the battery. A 6-cell or 9-cell is even better. That is a pretty long list for a budget of around $1200. I searched around the internet and could not buy this machine prebuilt for under $1200. That was even with coupons and my company’s 10% Dell discount. The only way that I would get a machine like this was to buy a prebuilt and replace parts. I chose the  Lenovo Y560 on Newegg to start as my base. Below is a top-down picture of it.   Part 1: The Hardware The Specs for this machine: Color :  GrayOperating System : Windows 7 Home Premium 64-bitCPU Type : Intel Core i7-740QM(1.73GHz)Screen : 15.6" WXGAMemory Size : 4GB DDR3Hard Disk : 500GBOptical Drive : DVD±R/RWGraphics Card : ATI Mobility Radeon HD 5730Video Memory : 1GBCommunication : Gigabit LAN and WLANCard slot : 1 x Express Card/34Battery Life : Up to 3.5 hoursDimensions : 15.20" x 10.00" x 0.80" - 1.30"Weight : 5.95 lbs. This computer met most of the requirements above except that it didn’t come with an SSD or have 8GB of DDR3 Memory. So, I needed to start shopping except this time for an SSD. I asked around on twitter and other hardware forums and everyone pointed me to the Crucial C300 SSD. After checking prices of the drive, it was going to cost an extra $275 bucks and I was going from a spacious 500GB drive to 128GB. After watching some of the SSD videos on YouTube I started feeling better. Below is a pic of the Crucial C300 SSD. The second thing that I needed to upgrade was the RAM. It came with 4GB of DDR3 RAM, but it was slow. I decided to buy the Crucial 8GB (4GB x 2) Kit from Newegg. This RAM cost an extra $120 and had a CAS Latency of 7. In the end this machine delivered everything that I wanted and it cost around $1300. You are probably saying, well your budget was $1200. I have spare parts that I’m planning on selling on eBay or Anandtech.  =) If you are interested then shoot me an email and I will give you a great deal mbcrump[at]gmail[dot]com. 500GB Laptop 7200RPM HDD 4GB of DDR3 RAM (2GB x 2) faceVision HD 720p Camera – Unopened In the end my Windows Experience Rating of the SSD was 7.7 and the CPU 7.1. The max that you can get is a 7.9. Part 2: The Software I’m very lucky that I get a lot of software for free. When choosing a laptop, the OS really doesn’t matter because I would never keep the bloatware pre-installed or Windows 7 Home Premium on my main development machine. Matter of fact, as soon as I got the laptop, I immediately took out the old HDD without booting into it. After I got the SSD into the machine, I installed Windows 7 Ultimate 64-Bit. The BIOS was out of date, so I updated that to the latest version and started downloading drivers off of Lenovo’s site. I had to download the Wireless Networking Drivers to a USB-Key before I could get my machine on my wireless network. I also discovered that if the date on your computer is off then you cannot join the Windows 7 Homegroup until you fix it. I’m aware that most people like peeking into what programs other software developers use and I went ahead and listed my “essentials” of a fresh build. I am a big Silverlight guy, so naturally some of the software listed below is specific to Silverlight. You should also check out my master list of Tools and Utilities for the .NET Developer.

  • SQL SERVER – Recover the Accidentally Renamed Table

    - by pinaldave
    I have no answer to following question. I saw a desperate email marked as urgent delivered in my mailbox. “I accidentally renamed table in my SSMS. I was scrolling very fast and I made mistakes. It was either because I double clicked or clicked on F2 (shortcut key for renaming). However, I have made the mistake and now I have no idea how to fix this. I am in big trouble. Help me get my original tablename.” I have seen many similar scenarios in my life and they give me a very good opportunity to preach wisdom but when the house is burning, we cannot talk about how we should have conserved the water earlier. The goal at that point is to put off the fire as fast as we can. I decided to answer this email with my best knowledge. If you have renamed the table, I think you pretty much is out of luck. Here are few things which you can do which can give you idea about what your tablename can be if you are lucky. Method 1: (Not Recommended but try your luck) Check your naming convention of your system. I have often seen that many organizations name their index as IX_TableName_Colms or name their keys as FK_TableName1_TableName2_Cols. If your organization is following the same you can get the name from your table, you may refer your keys. Again, note that this is quite possible that your tablename was already renamed and your keys were not updated. This can easily lead you to select incorrect name. I think follow this if you are confident or move to the next method. Method 2: (Not Recommended but try your luck) This method is also based on your orgs naming convention. If you use the name of the table in any columnname (some organizations use tablename in their incremental identity column name), you can get that name from there. Method 3: (Not Recommended but try your luck) If you know where your table was used in your stored procedures, you can script your stored procedure and find the name of the table back. Method 4: (Try your luck) All the best organizations first create a data model of the schema and there is good chance that this table is used there, you should take your chances and refer original document. If your organization is good at managing docs or source code, you will get the name of the table back for sure. Method 5: (It WORKS but try on a development server) There is no sure way to get you the name of the table which you accidentally renamed however, there is one way which will work for sure. You need to take your latest full backup and restore it on your development server (remember not on production or where you have renamed this column). Now restore latest differential file of the full backup. Now restore all the log files one by one making sure that you are restoring before the point of time of you renamed the tablename. Now go to explore and this will give you the name of the table which you have renamed. If you are confident that the same table existed with the same name when the last full backup was made, you do not have to go to all the steps. You can just get the name of the table directly from last backup’s restore. Read the article about Backup Timeline. Wisdom: How can I miss to preach wisdom when I get the opportunity to do so? Here are a few points to remember. Use a different account to explore production environment. Do not use the same account which have all the rights and permissions all the time. Use the account which has read only permissions if there are no modification required. Use policy based management to prevent changes which are accidental. If there was policy of valid names, the accidental change of the table was not possible unless it was intentional delibarate changes. Have a proper auditing of the system in place. You can use DDL triggers but be careful with its usage (get it reviewed properly first). (Add your suggestion here) I guess Method 5 will work all the time (using point in time restore). Everything else is chance of luck and if you are lucky are bad – you will get further incorrect name. Now go back and read the first line of this blog. Out of five method four methods are just lucky guesses. The method 5 will work but again it is a lengthy process if the size of the database is huge or if you do not have full backup. Did I miss anything obvious? Please leave a comment and I will publish your answer with due credit.

  • Developing Schema Compare for Oracle (Part 3): Ghost Objects

    - by Simon Cooper
    In the previous blog post, I covered how we solved the problem of dependencies between objects and between schemas. However, that isn’t the end of the issue. The dependencies algorithm I described works when you’re querying live databases and you can get dependencies for a particular schema direct from the server, and that’s all well and good. To throw a (rather large) spanner in the works, Schema Compare also has the concept of a snapshot, which is a read-only compressed XML representation of a selection of schemas that can be compared in the same way as a live database. This can be useful for keeping historical records or a baseline of a database schema, or comparing a schema on a computer that doesn’t have direct access to the database. So, how do snapshots interact with dependencies? Inter-database dependencies don't pose an issue as we store the dependencies in the snapshot. However, comparing a snapshot to a live database with cross-schema dependencies does cause a problem; what if the live database has a dependency to an object that does not exist in the snapshot? Take a basic example schema, where you’re only populating SchemaA: SOURCE   TARGET (using snapshot) CREATE TABLE SchemaA.Table1 ( Col1 NUMBER REFERENCES SchemaB.Table1(col1));   CREATE TABLE SchemaA.Table1 ( Col1 VARCHAR2(100)); CREATE TABLE SchemaB.Table1 ( Col1 NUMBER PRIMARY KEY);   CREATE TABLE SchemaB.Table1 ( Col1 VARCHAR2(100)); In this case, we want to generate a sync script to synchronize SchemaA.Table1 on the database represented by the snapshot. When taking a snapshot, database dependencies are followed, but because you’re not comparing it to anything at the time, the comparison dependencies algorithm described in my last post cannot be used. So, as you only take a snapshot of SchemaA on the target database, SchemaB.Table1 will not be in the snapshot. If this snapshot is then used to compare against the above source schema, SchemaB.Table1 will be included in the source, but the object will not be found in the target snapshot. This is the same problem that was solved with comparison dependencies, but here we cannot use the comparison dependencies algorithm as the snapshot has not got any information on SchemaB! We've now hit quite a big problem - we’re trying to include SchemaB.Table1 in the target, but we simply do not know the status of this object on the database the snapshot was taken from; whether it exists in the database at all, whether it’s the same as the target, whether it’s different... What can we do about this sorry state of affairs? Well, not a lot, it would seem. We can’t query the original database, as it may not be accessible, and we cannot assume any default state as it could be wrong and break the script (and we currently do not have a roll-back mechanism for failed synchronizes). The only way to fix this properly is for the user to go right back to the start and re-create the snapshot, explicitly including the schemas of these 'ghost' objects. So, the only thing we can do is flag up dependent ghost objects in the UI, and ask the user what we should do with it – assume it doesn’t exist, assume it’s the same as the target, or specify a definition for it. Unfortunately, such functionality didn’t make the cut for v1 of Schema Compare (as this is very much an edge case for a non-critical piece of functionality), so we simply flag the ghost objects up in the sync wizard as unsyncable, and let the user sort out what’s going on and edit the sync script as appropriate. There are some things that we do do to alleviate somewhat this rather unhappy situation; if a user creates a snapshot from the source or target of a database comparison, we include all the objects registered from the database, not just the ones in the schemas originally selected for comparison. This includes any extra dependent objects registered through the comparison dependencies algorithm. If the user then compares the resulting snapshot against the same database they were comparing against when it was created, the extra dependencies will be included in the snapshot as required and everything will be good. Fortunately, this problem will come up quite rarely, and only when the user uses snapshots and tries to sync objects with unknown cross-schema dependencies. However, the solution is not an easy one, and lead to some difficult architecture and design decisions within the product. And all this pain follows from the simple decision to allow schema pre-filtering! Next: why adding a column to a table isn't as easy as you would think...

  • Trigger Happy

    - by Tim Dexter
    Its been a while, I know, we’ll say no more OK? I’ll just write …In the latest BIP 11.1.1.6 release and if I’m really honest; the release before this (we'll call it dot 5 for brevity.) The boys and gals in the engine room have been real busy enhancing BIP with some new functionality. Those of you that use the scheduling engine in OBIEE may already know and use the ‘conditional scheduling’ feature. This allows you to be more intelligent about what reports get run and sent to folks on a scheduled basis. You create a ‘trigger’ analysis (answer) that is executed at schedule time prior to the main report. When the schedule rolls around, the trigger is run, if it returns rows, then the main report is run and delivered. If there are no rows returned, then the main report is not run. Useful right? Your users are not bombarded with 20 reports in their inbox every week that they need to wade throu. They get a handful that they know they need to look at. If you ensure you use conditional formatting in the report then they can find the anomalous data in the reports very quickly and move on to the rest of their day more quickly. You could even think of OBIEE as a virtual team member, scouring the data on your behalf 24/7 and letting you know when its found an issue.BI Publisher, wanting the team t-shirt and the khaki pants, has followed suit. You can now set up ‘triggers’ for it to execute before it runs the main report. Just like its big brother, if the scheduled report trigger returns rows of data; it then executes the main report. Otherwise, the report is skipped until the next schedule time rolls around. Sound familiar?BIP differs a little, in that you only need to construct a query to act as the trigger rather than a complete report. Let assume we have a monthly wage by department report on a schedule. We only want to send the report to managers if their departmental wages reach and/or exceed a certain amount. The toughest part about this is coming up with the SQL to test the business rule you want to implement. For my example, its not that tough: select d.department_name, sum(e.salary) as wage_total from employees e, departments d where d.department_id = e.department_id group by d.department_name having sum(e.salary) > 230000 We're looking for departments where the wage cost is greater than 230,000 Dexter Dollars! With a bit of messing I found out you can parametrize the query. Users can then set a value at schedule time if they need to. To create the trigger is straightforward enough. You can create multiple triggers for users to select at schedule time. Notice I also used a parameter in the query, :wamount. Note the matching parameter in the tree on the left. You also dont need to return multiple columns, one is fine, the key is if there are rows returned. You can build the rest of your report as usual. At scheduling time the Schedule tab has a bit more on it. If your users want to set the trigger, they check the Use Trigger box. The page will then pop fields to pick the appropriate trigger they want to use, even a trigger on another data model if needed. Note it will also ask for the parameter value associated with the trigger. At this point you should note that the data model does not make a distinction between trigger and data model (extract) parameters. So users will see the parameters on the General and Schedule tabs. If per chance you do need to just have a trigger parameters. You can just hide them from the report using the Parameters popup in the report designer, just un-check the 'Show' box I have tested the opposite case where you do not want main report parameters seen in the trigger section. BIP handles that for you! Once the report hits its allotted schedule time, the trigger is executed. Based on the results the report will either run or be 'skipped.' Now, you have a smarter scheduler that will only deliver reports when folks need to see them and take action on the contents. More official info here for developers and here for users.

  • The first day of JavaOne is already over!

    - by delabassee
    In the past Sunday used to be a more relaxing day with ‘just’ some JavaOne activities going on. Sunday used to be a soft day to prepare yourself for an exhausting week. This is now over as JavaOne is expanding; Sunday is now an integral part of the conference. One of the side effect of this extra day is that some activities related to JavaOne and OpenWorld such as MySQL Connect are being push to start a day earlier on Saturday (can you spot the pattern here?). On the GlassFish front, Sunday was a very busy day! It started at the Moscone Center with the annual GlassFish Community Event where the Java EE 7 and GF 4 roadmaps were presented and discussed. During the event, different GlassFish users such as ZeroTurnaround (the JRebel guys), Grupo RBS and IDR Solutions shared their views on GF, why they like GF but also what could be improved. The event was also a forum for the GF community to exchange with some of the key Java EE / GlassFish Oracle Executives and the different GF team members. The Strategy keynote and the Technical keynote were held in the Masonic Auditorium later in the after-noon. Oracle executives have presented the plans for Java SE, Java FX and Java EE. As on-demand replays will be available soon, I will not summarize several hours of content but here are some personal takeaways from those keynotes. Modularity Modularity is a big deal. We know by now that Project Jigsaw will not be ready for Java SE 8 but in any case, it is already possible (and encouraged) to test Jigsaw today. In the future, Java EE plan to rely on the modularity features provided by Java SE, so Project Jigsaw is also relevant for Java EE developers. Shorter term, to cover some of the modular requirements, Java SE will adopt the approach that was used for Java EE 6 and the notion of Profiles. This approach does not define a module system per say; Profiles is a way to clearly define different subsets of Java SE to fulfill different needs (e.g. the full JRE is not required for a headless application). The introduction of different Profiles, from the Base profile (10mb) to the Full Profile (+50mb), has been proposed for Java SE 8. Embedded Embedded is a strong theme going forward for the Java Plaform. There is now a dedicated program : Java Embedded @ JavaOne Java by nature (e.g. platform independence, built-in security, ability easily talks to any back-end systems, large set of skills available on the market, etc.) is probably the most suited platform for the Internet of Things. You can quickly be up-to-speed and develop services and applications for that space just by using your current Java skills. All you need to start developing on ARM is a 35$ Raspberry Pi ARM board (25$ if you are cheap and can live without an ethernet connection) and the recently released JDK for Linux/ARM. Obviously, GlassFish runs on Raspberry Pi. If you wan to go further in the embedded space, you should take a look Java SE Embedded, an optimized, low footprint, Java environment that support the major embedded architectures (ARM, PPC and x86). Finally, Oracle has recently introduced Java Embedded Suite, a new solution that brings modern middleware capabilities to the embedded space. Java Embedded Suite is an optimized solution that leverage Java SE Embedded but also GlassFish, Jersey and JavaDB to deploy advanced value added capabilities (eg. sensor data filtering and) deeper in the network, closer to the devices. JavaFX JavaFX is going strong! Starting from Java SE 7u6, JavaFX is bundled with the JDK. JavaFX is now available for all the major desktop platforms (Windows, Linux and Mac OS X). JavaFX is now also available, in developer preview, for low end device running Linux/ARM. During the keynote, JavaFX was shown running on a Raspberry Pi! And as announced during the keynote, JavaFX should be fully open-sourced by the end of the year; contributions are welcome!. There is a strong momentum around JavaFX, it’s the ideal client solution for the Java platform. A client layer that works perfectly with GlassFish on the back-end. If you were not convince by JavaFX, it’s time to reconsider it! As an old Chinese proverb say “One tweet is worth a thousand words!” HTML5, Project Avatar and Java EE 7 HTML5 got a lot of airtime too, it was covered during the Java EE 7 section of the keynote. Some details about Project Avatar, Oracle’s incubator project for a TSA (Thin Server Architecture) solution, were diluted and shown during the keynote. On the tooling side, Project Easel running on NetBeans 7.3 beta was demo’ed, including a cool NetBeans debugging session running in Chrome! HTML 5, Project Avatar and Java EE 7 deserve separate posts... Feedback We need your feedback! There are many projects, JSRs and products cooking : GlassFish 4, Project Jigsaw, Concurrency Utilities for Java EE (JSR 236), OpenJFX, OpenJDK to name just a few. Those projects, those specifications will have a profound impact on the Java platform for the years to come! So if you have the opportunity, download, install, learn, tests them and give feedback! Remember, you can "Make the Future Java!" Finally, the traditional GlassFish Party at the Thirsty Bear concluded the first JavaOne day. This party is another place where the community can freely exchange with the GlassFish team in a more relaxed, more friendly (but sometime more noisy) atmosphere. Arun has posted a set of pictures to reflect the atmosphere of the keynotes and the GlassFish party. You can find more details on the others Java EE and GlassFish activities here.

  • Subscribable World Cup 2010 Calendar

    - by jamiet
    I bang on quite a lot on this blog about ways in which data can get published over the web and one of the most interesting ways, in my opinion, of publishing data in a structured manner that is well understood is to use the iCalendar specification. There isn’t much information in the world that doesn’t have some concept of “when” so iCalendar is a great way of distributing that information. You have probably used iCalendar at some point without even knowing about it. All files with a .ics suffix are iCalendar format files and that is why you can happily import them into Outlook, Hotmail Calendar, Google Calendar etc… where they can be parsed and have the semantic data (when, where and who) extracted from them. Importing of iCalendar format data is really only half the trick though; in my opinion the real value of iCalendar-formatted calendar is the ability to subscribe to them. Subscribing has a simple benefit over importing but that single benefit is of massive importance: a subscriber to an iCalendar calendar can periodically check to see if any updates have been made and, if they have, automatically update the local copy. The real benefit to the user is the productivity gain – a single update to an iCalendar means that all subscribers are automatically made aware of the change and there is zero effort on the part of the subscriber; as my former colleague Howard van Rooijen is fond of saying, “work smarter not harder” – nowhere is this edict more ably demonstrated than subscribing versus importing of calendars. If you want to read some more thoughts about iCalendar then go and read my past blog post Calendar syndication - My big hope for 2009's breakthrough technology or better still go and seek out Jon Udell who speaks very authoritatively on the issue of iCalendar. With this subject of iCalendar on my mind I was interested to discover (via Steve Clayton’s blog post Download the world cup fixtures) that the BBC had made a .ics file available containing all of the matches in the upcoming World Cup. As you can probably guess this was a file that was made available so that it could be imported into your calendar of choice. It had one obvious downside though, right now nobody knows who is going to be playing in the knock-out stages so the calendar looks like this: with no teams being named after 25th June. How much more useful would this calendar have been if the BBC had made it possible to subscribe to the calendar instead, thus the calendar could be updated with the teams for the knock out stages when they are known and every subscriber would have a permanently up-to-date record of all the fixtures in their calendar. Better still, the calendar could be updated with match results as well or perhaps even post a match report from the BBC sport pages; when calendars are made subscribable a sea of opportunity opens up for distribution of information. So with that in mind I have decided to go one better than the BBC. I have imported their .ics into a brand new Hotmail calendar and made it publicly available at the following URLs: HTML http://cid-dc1ed121af0476be.calendar.live.com/calendar/World+Cup+2010/index.html iCalendar webcal://cid-dc1ed121af0476be.calendar.live.com/calendar/World+Cup+2010/calendar.ics The link you’re really interested in is the second one - click on that and it should open up in your calendar software of choice. Or, if you want to view it in an online calendar such as Hotmail Calendar or Google Calendar, copy and paste that URL into the appropriate place. Some people have told me they’re having trouble with the iCalendar link in which case hit the HTML link and then click “View ICS” at the resultant web page: I shall endeavour to keep the calendar updated throughout the World Cup and even if I don’t you’re no worse off than if you had imported the BBC’s .ics file so why not give it a try? If I do keep it up to date then you will have a permanent record of the 2010 World Cup available in your calendar. Forever. If you have your calendar synced to your smartphone then you’ll be carrying match reports around with you without you having to do a single thing. Surely that’s worth a quick click isn’t it?   If you have any thoughts let me have them in the comments below.

  • Part 1 - 12c Database and WLS - Overview

    - by Steve Felts
    The download of Oracle 12c database became available on June 25, 2013.  There are some big new features in 12c database and WebLogic Server will take advantage of them. Immediately, we will support using 12c database and drivers with WLS 10.3.6 and 12.1.1.  When the next version of WLS ships, additional functionality will be supported (those rows in the table below with all "No" values will get a "Yes).  The following table maps the Oracle 12c Database features supported with various combinations of currently available WLS releases, 11g and 12c Drivers, and 11g and 12c Databases. Feature WebLogic Server 10.3.6/12.1.1 with 11g drivers and 11gR2 DB WebLogic Server 10.3.6/12.1.1 with 11g drivers and 12c DB WebLogic Server 10.3.6/12.1.1 with 12c drivers and 11gR2 DB WebLogic Server 10.3.6/12.1.1 with 12c drivers and 12c DB JDBC replay No No No Yes (Active GridLink only in 10.3.6, add generic in 12.1.1) Multi Tenant Database No Yes (except set container) No Yes (except set container) Dynamic switching between Tenants No No No No Database Resident Connection pooling (DRCP) No No No No Oracle Notification Service (ONS) auto configuration No No No No Global Database Services (GDS) No Yes (Active GridLink only) No Yes (Active GridLink only) JDBC 4.1 (using ojdbc7.jar files & JDK 7) No No Yes Yes  The My Oracle Support (MOS) document covering this is "WebLogic Server 12.1.1 and 10.3.6 Support for Oracle 12c Database [ID 1564509.1]" at the link https://support.oracle.com/epmos/faces/DocumentDisplay?id=1564509.1. The following documents are also key references:12c Oracle Database Developer Guide http://docs.oracle.com/cd/E16655_01/appdev.121/e17620/toc.htm 12c Oracle Database Administrator's Guide http://docs.oracle.com/cd/E16655_01/server.121/e17636/toc.htm . I plan to write some related blog articles not to duplicate existing product documentation but to introduce the features, provide some examples, and tie together some information to make it easier to understand. How do you get started with 12c?  The easiest way is to point your data source at a 12c database.  The only change on the WLS side is to update the URL in your data source (assuming that you are not just upgrading your database).  You can continue to use the 11.2.0.3 driver jar files that shipped with WLS 10.3.6 or 12.1.1.  You shouldn't see any changes in your application.  You can take advantage of enhancements on the database side that don't affect the mid-tier.  On the WLS side, you can take advantage of using Global Data Service or connecting to a tenant in a multi-tenant database transparently. If you want to use the 12c client jar files, it's a bit of work because they aren't shipped with WLS and you can't just drop in ojdbc6.jar as in the old days.  You need to use a matched set of jar files and they need to come before existing jar files in the CLASSPATH.  The MOS article is written from the standpoint that you need to get the jar files directly - download almost 1G and install over 600M footprint to get 15 jar files.  Assuming that you have the database installed and you can get access to the installation (or ask the DBA), you need to copy the 15 jar files to each machine with a WLS installation and get them in your CLASSPATH.  You can play with setting the PRE_CLASSPATH but the more practical approach may be to just update WL_HOME/common/bin/commEnv.sh directly.  There's a change in the transaction completion behavior (read the MOS) so if you think you might run into that, you will want to set -Doracle.jdbc.autoCommitSpecCompliant=false.  Also if you are running with Active GridLink, you must set -Doracle.ucp.PreWLS1212Compatible=true (how's that for telling you that this is fixed in WLS 12.1.2).  Once you get the configuration out of the way, you can start using the new ojdbc7.jar in place of the ojdbc6.jar to get the new JDBC 4.1 API's.  You can also start using Application Continuity.  This feature is also known as JDBC Replay because when a connection fails you get a new one with all JDBC operations up to the failure point automatically replayed.  As you might expect, there are some limitations but it's an interesting feature.  Obviously I'm going to focus on the 12c database features that we can leverage in WLS data source.  You will need to read other sources or the product documentation to get all of the new features.

  • 5 Things I Learned About the IT Labor Shortage

    - by Oracle Accelerate for Midsize Companies

It’s time to wrap up the series that I started back in April, “The Growing IT Labor Shortage: Are You Feeling It?” Even in a time of relatively high unemployment, labor shortages exist depending on many factors, including location, industry, IT requirements, and company size. According to Manpower Groups 2013 Talent Shortage Survey, 35% of hiring managers globally are having difficulty filling jobs. Their top three challenges in filling jobs are: 1. lack of technical competencies (hard skills) 2. Lack of available applicants 3. Lack of experience The same report listed Technicians as the most difficult position to fill in the United States For most companies, Human Capital and Talent Management have never been more strategic and they are striving for ways streamline processes, reduce turnover, and lower costs (see this Oracle whitepaper, “ Simplify Workforce Management and Increase Global Agility”). Everyone I spoke to—partner, customer, and Oracle experts—agreed that it can be extremely challenging to hire and retain IT talent in today’s labor market. And they generally agreed on the causes: a. IT is so pervasive that there are myriad moving parts requiring support and expertise, b. thus, it’s hard for university graduates to step in and contribute immediately without experience and specialization, c. big IT companies generally aren’t the talent incubators that they were in the freewheeling 90’s due to bottom line pressures that require hiring talent that can hit the ground running, and d. it’s often too expensive for resource-strapped midsize companies to invest the time and money required to get graduates up to speed. Here are my top lessons learned from my conversations with the experts. 1. A Better Title Would Have Been, “The Challenges of Finding and Retaining IT Talent That Matches Your Requirements” There are more applicants than jobs but it’s getting tougher and tougher to find individuals that perfectly fit each and every role. Top performing companies are increasingly looking to hire the “almost ready”, striving to keep their existing talent more engaged, and leveraging their employee’s social and professional networks to quickly narrow down candidate searches (here’s another whitepaper, “A Strategic Approach to Talent Management”). 2. Size Matters—But So Does Location Midsize companies must strive to build cultures that compete favorably with what large enterprises can offer, especially when they aren’t within commuting distance of IT talent strongholds. They can’t always match the compensation and benefits offered by large enterprises so it's paramount to offer candidates high quality of life and opportunities to build their resumes in alignment with their long term career aspirations. 3. Get By With a Little Help From Your Friends It doesn’t always make sense to invest time and money in training an employee on a task they will not perform frequently. Or get in a bidding war for talent with skills that are rare and in high demand. Many midsize companies are finding that it makes good economic sense to contract with partners for remote support rather than trying to divvy up each and every role amongst their lean staff. Internal staff can be assigned to roles that will have the highest positive impact on achieving organizational goals. 4. It’s Actually Both “What You Know” AND “Who You Know” If I was hiring someone today I would absolutely leverage the social and professional networks of my co-workers. Period. Most research shows that hiring in this manner is less expensive and time consuming AND produces better results. There is also some evidence that suggests new hires from employees’ networks have higher job performance and retention rates. 5. I Have New Respect for Recruiters and Hiring Managers My hats off to them—it’s not easy hiring and retaining top talent with today’s challenges. Check out the infographic, “A New Day: Taking HR from Chaos to Control”, on Oracle’s Human Capital Management solutions home page. You can also explore all of Oracle’s HCM solutions from that page based on your role. You can read all the posts in this series by clicking on the links in the right sidebar. Stay tuned…we’ll continue to post thought leadership on HCM and Talent Management topics.

  • Microsoft TechEd 2010 - Day 2 @ Bangalore

    - by sathya
    Microsoft TechEd 2010 - Day 2 @ Bangalore Today is the day 2 @ Microsoft TechEd 2010. We had lot of technical sessions as usual there were many tracks going on side by side and I was attending the Web simplified track, Which comprised of the following sessions :   Developing a scalable Media Application using ASP.NET MVC - This was a kind of little advanced stuff. Anyways I couldn't understand much because this was not my piece of cake and I havent worked on this before ASP.Net MVC Unplugged - This was really great because this session covered from the basics of MVC showing what is Model,View and Controller and how it worked and the speaker went into the details of the same. Building RESTful Applications with the Open Data Protocol - There were some concepts explained about this from the basics on how to build RESTful Services and it went on till some advanced configurations of the same. Developing Scalable Web Applications with AppFabric Caching - This session showed about the integration of AppFabric with the .Net Web Applications. Instead of using Inproc Sessions, we can use this AppFabric as a substitute for Caching and outofProc Session Storage without writing code and doing a little bit of configurations which brings in High Scalability, performance to our applications. (But unfortunately there were no demos for this session ) Deep Dive : WCF RIA Services - This session was also an interactive one, in this the speaker presented from the basics of WCF and took a Book Store Application as a sample and explained all details concepts on linking with RIA Services   Apart from these sessions, in between there happened some small events in the breaks like Some discussions about Technology, Innovations Music Jokes Mimicry, etc. And on doing all these things, the developers were given some kool gifts / goodies like USBs, T-Shirts, etc. And today I got a chance to do the following certification : (70-562) Microsoft Certified Technology Specialist in .NET 3.5 Web Applications Since I already have an MCTS in .NET 2.0, I wanted to do an MCPD and for doing the same I was required to do an update to my MCTS with the .NET 3.5 framework and I did the same I cleared it and now am an MCTS in .NET 3.5 Web Apps And on doing this I got a T-Shirt and they gave something called Learning $ of worth 30$. And in various stalls for attending each quiz or some game or some referrals we got some Learning $ which we can redeem later based on our Total Learning $. I got 105 $ which i was able to redeem and got a Microsoft Learning BagPack, 1 free Microsoft certification offer, a laptop light and an e-learning content activated. And after all these sessions and small events, we had something called Demo Extravaganza like I mentioned yesterday. This was a great funfilled event with lot of goodies for the attendees. There were some lucky draw which enabled 2 attendees to get Netbooks (Sponsored by Intel) and 1 attendee to get X-box (Sponsored by Citrix). After Choosing the raffle in the lucky draw they kept it on a device called Microsoft Surface which is a kind of big touch screen device and on putting the raffle on that it detected the code of the attendee and said intelligently how many sessions that person has attended and if he has attended more than 5 he got a Netbook and this was coded by a guy called Imran. Apart from they showed demos on : Research by 2 Tamilnadu students from Krishna Arts and Science college, taken 1200 photographs of their college from different angles and put that up in Bing maps using silverlight and linked with Photosynth, which showed a 3d view of their college based on the photos they uploaded Reasearch by Microsoft on Panaramic HD views of the images. One young guy from Microsoft Research showed a demo of this on Srivilliputhur Andal Temple, in Tamil Nadu and its history with a panoramic view of the temple and the near by places with narration of the historical information on the same and with the videos embedded in it with high definition images which we can zoom to a very detailed level. Some Demo on a business app with Silverlight, Business Intelligence (BI) and maps integrated. It showed the sales of a particular product across locations. Some kool demos by 2 geeks who used Robots to show their development talents. 2 Robots fought with each other 2 Robots danced in sync for the A.R. Rehman song Humma Humma... A dream home project by Raman. He is currently using the same in his home too. Robots are controlling his home currently. They showed a video on this. Here are the list of activities that Robot does for him When he reads a book, robot automatically scans that and shows that image of that person in the screen (TV or comp) in front of him. It shows a wikipedia about that person. It says that person is not in linked in. do you want to add him If he sees an IPL Match news in the book and smiles it understands he is interested in that and opens a website related to that and shows the current game and the scorecard. It cooks for him It cleans the room for him whenever he leaves the house when he is doing something if some intruder comes inside his house his computer automatically switches his screen showing the video of the person coming inside. When he wakes up it automatically opens up the system, loads his mails and the news by the side, etc. Some Demos on Microsoft Pivot. This was there in livelabs but it is now available in getpivot.com its a pivoting of the pictorial data based on some categories and filters on the searches that we do. And finally on filling up some feedback forms we got T-Shirts and Microsoft Visual Studio 2010 Training Kit CDs. Whats more on TechEd??? Stay tuned!!! Will update you soon on the other happenings!! PS : I typed a lot of content for more than a hour but I pressed a backspace and it went to the previous page and all my content were lost and I was not able to retrieve the same and I typed everything again.

  • Blog Buzz - Devoxx 2011

    - by Janice J. Heiss
    Some day I will make it to Devoxx – for now, I’m content to vicariously follow the blogs of attendees and pick up on what’s happening.  I’ve been doing more blog "fishing," looking for the best commentary on 2011 Devoxx. There’s plenty of food for thought – and the ideas are not half-baked.The bloggers are out in full, offering useful summaries and commentary on Devoxx goings-on.Constantin Partac, a Java developer and a member of Transylvania JUG, a community from Cluj-Napoca/Romania, offers an excellent summary of the Devoxx keynotes. Here’s a sample:“Oracle Opening Keynote and JDK 7, 8, and 9 Presentation•    Oracle is committed to Java and wants to provide support for it on any device.•    JSE 7 for Mac will be released next week.•    Oracle would like Java developers to be involved in JCP, to adopt a JSR and to attend local JUG meetings.•    JEE 7 will be released next year.•    JEE 7 is focused on cloud integration, some of the features are already implemented in glassfish 4 development branch.•    JSE 8 will be release in summer of 2013 due to “enterprise community request” as they can not keep the pace with an 18    month release cycle.•    The main features included in JSE8 are lambda support, project Jigsaw, new Date/Time API, project Coin++ and adding   support for sensors. JSE 9 probably will focus on some of these features:1.    self tuning JVM2.    improved native language integration3.    processing enhancement for big data4.    reification (adding runtime class type info for generic types)5.    unification of primitive and corresponding object classes6.    meta-object protocol in order to use type and methods define in other JVM languages7.    multi-tenancy8.    JVM resource management” Thanks Constantin! Ivan St. Ivanov, of SAP Labs Bulgaria, also commented on the keynotes with a different focus.  He summarizes Henrik Stahl’s look ahead to Java SE 8 and JavaFX 3.0; Cameron Purdy on Java EE and the cloud; celebrated Java Champion Josh Bloch on what’s good and bad about Java; Mark Reinhold’s quick look ahead to Java SE 9; and Brian Goetz on lambdas and default methods in Java SE 8. Here’s St. Ivanov’s account of Josh Bloch’s comments on the pluses of Java:“He started with the virtues of the platform. To name a few:    Tightly specified language primitives and evaluation order – int is always 32 bits and operations are executed always from left  to right, without compilers messing around    Dynamic linking – when you change a class, you need to recompile and rebuild just the jar that has it and not the whole application    Syntax  similarity with C/C++ – most existing developers at that time felt like at home    Object orientations – it was cool at that time as well as functional programming is today    It was statically typed language – helps in faster runtime, better IDE support, etc.    No operator overloading – well, I’m not sure why it is good. Scala has it for example and that’s why it is far better for defining DSLs. But I will not argue with Josh.”It’s worth checking out St. Ivanov’s summary of Bloch’s views on what’s not so great about Java as well. What's Coming in JAX-RS 2.0Marek Potociar, Principal Software Engineer at Oracle and currently specification lead of Java EE RESTful web services API (JAX-RS), blogged on his talk about what's coming in JAX-RS 2.0, scheduled for final release in mid-2012.  Here’s a taste:“Perhaps the most wanted addition to the JAX-RS is the Client API, that would complete the JAX-RS story, that is currently server-side only. In JAX-RS 2.0 we are adding a completely interface-based and fluent client API that blends nicely in with the existing fluent response builder pattern on the server-side. When we started with the client API, the first proposal contained around 30 classes. Thanks to the feedback from our Expert Group we managed to reduce the number of API classes to 14 (2 of them being exceptions)! The resulting is compact while at the same time we still managed to create an API that reflects the method invocation context flow (e.g. once you decide on the target URI and start setting headers on the request, your IDE will not try to offer you a URI setter in the code completion). This is a subtle but very important usability aspect of an API…” Obviously, Devoxx is a great Java conference, one that is hitting this year at a time when much is brewing in the platform and beginning to be anticipated.

  • Stumbling Through: Making a case for the K2 Case Management Framework

    I have recently attended a three-day training session on K2s Case Management Framework (CMF), a free framework built on top of K2s blackpearl workflow product, and I have come away with several different impressions for some of the different aspects of the framework.  Before we get into the details, what is the Case Management Framework?  It is essentially a suite of tools that, when used together, solve many common workflow scenarios.  The tool has been developed over time by K2 consultants that have realized they tend to solve the same problems over and over for various clients, so they attempted to package all of those common solutions into one framework.  Most of these common problems involve workflow process that arent necessarily direct and would tend to be difficult to model.  Such solutions could be achieved in blackpearl alone, but the workflows would be complex and difficult to follow and maintain over time.  CMF attempts to simplify such scenarios not so much by black-boxing the workflow processes, but by providing different points of entry to the processes allowing them to be simpler, moving the complexity to a middle layer.  It is not a solution in and of itself, development is still required to tie the pieces together. CMF is under continuous development, both a plus and a minus in that bugs are fixed quickly and features added regularly, but it may be difficult to know which versions are the most stable.  CMF is not an officially supported K2 product, which means you will not get technical support but you will get access to the source code. The example given of a business process that would fit well into CMF is that of a file cabinet, where each folder in said file cabinet is a case that contains all of the data associated with one complaint/customer/incident/etc. and various users can access that case at any time and take one of a set of pre-determined actions on it.  When I was given that example, my first thought was that any workflow I have ever developed in the past could be made to fit this model there must be more than just this model to help decide if CMF is the right solution.  As the training went on, we learned that one of the key features of CMF is SharePoint integration as each case gets a SharePoint site created for it, and there are a number of excellent web parts that can be used to design a portal for users to get at all the information on their cases.  While CMF does not require SharePoint, without it you will be missing out on a huge portion of functionality that CMF offers.  My opinion is that without SharePoint integration, you may as well write your workflows and other components the old fashioned way. When I heard that each case gets its own SharePoint site created for it, warning bells immediately went off in my head as I felt that depending on the data load, a CMF enabled solution could quickly overwhelm SharePoint with thousands of sites so we have yet another deciding factor for CMF:  Just how many cases will your solution be creating?  While it is not necessary to use the site-per-case model, it is one of the more useful parts of the framework.  Without it, you are losing a big chunk of what CMF has to offer. When it comes to developing on top of the Case Management Framework, it becomes a matter of configuring what makes up a case, what can be done to a case, where each action on a case should take the user, and then typing up actions to case statuses.  This last step is one that I immediately warmed up to, as just about every workflow Ive designed in the past needed some sort of mapping table to set the status of a work item based on the action being taken definitely one of those common solutions that it is good to see rolled up into a re-useable entity (and it gets a nice configuration UI to boot!).  This concept is a little different than traditional workflow design, in that you dont have to think of an end-to-end process around passing a case along a path, rather, you must envision the case as central object with workflow threads branching off of it and doing their own thing with the case data.  Certainly there can be certain workflow threads that get rather complex, but the idea is that they RELATE to the case, they dont BECOME the case (though it is still possible with action->status mappings to prevent certain actions in certain cases, so it isnt always a wide-open free for all of actions on a case). I realize that this description of the Case Management Framework merely scratches the surface on what the product actually can do, and I dont think Ive conclusively defined for what sort of business scenario you can make a case for Case Management Framework.  What I do hope to have accomplished with this post is to raise awareness of CMF there is a (free!) product out there that could potentially simplify a tangled workflow process and give (for free!) a very useful set of SharePoint web parts and a nice set of (free!) reports.  The best way to see if it will truly fit your needs is to give it a try did I mention it is FREE?  Er, ok, so it is free, but only obtainable at this time for K2 partnersDid you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

  • Productivity vs Security [closed]

    - by nerijus
    Really do not know is this right place to ask such a questions. But it is about programming in a different light. So, currently contracting with company witch pretends to be big corporation. Everyone is so important that all small issues like developers are ignored. Give you a sample: company VPN is configured so that if you have VPN then HTTP traffic is banned. Bearing this in mind can you imagine my workflow: Morning. Ok time to get latest source. Ups, no VPN. Let’s connect. Click-click. 3 sec. wait time. Ok getting source. Do I have emails? Ups. VPN is on, can’t check my emails. Need to wait for source to come up. Finally here it is! Ok Click-click VPN is gone. What is in my email. Someone reported a bug. Good, let’s track it down. It is in TFS already. Oh, dam, I need VPN. Click-click. Ok, there is description. Yea, I have seen this issue in stachoverflow.com. Let’s go there. Ups, no internet. Click-click. No internet. What? IPconfig… DHCP server kicked me out. Dam. Renew ip. 1..2..3. Ok internet is back. Google: site: stachoverflow.com 3 min. I have solution. Great I love stackoverflow.com. Don’t want to remember days where there was no stackoveflow.com. Ok. Copy paste this like to studio. Dam, studio is stalled, can’t reach files on TFS. Click-click. VPN is back. Get source out, paste my code. Grand. Let’s see what other comments about an issue in stackoverflow.com tells. Hmm.. There is a link. Click. Dammit! No internet. Click-click. No internet. DHCP kicked me out. Dammit. Now it is even worse: this happens 3-4 times a day. After certain amount of VPN connections open\closed my internet goes down solid. Only way to get internet back is reboot. All my browser tabs/SQL windows/studio will be gone. This happened just now when I am typing this. Back to issue I am solving right now: I am getting frustrated - I do not care about better solution for this issue. Let’s do it somehow and forget. This Click-click barrier between internet and TFS kills me… Sounds familiar? You could say there are VPN settings to change. No! This is company laptop, not allowed to do changes. I am very very lucky to have admin privileges on my machine. Most of developers don’t. So just learned to live with this frustration. It takes away 40-60 minutes daily. Tried to email company support, admins. They are too important ant too busy with something that just ignored my little man’s problem. Politely ignored. Question is: Is this normal in corporate world? (Have been in States, Canada, Germany. Never seen this.)

  • SQL SERVER – Curious Case of Disappearing Rows – ON UPDATE CASCADE and ON DELETE CASCADE – Part 1 of 2

    - by pinaldave
    Social media has created an Always Connected World for us. Recently I enrolled myself to learn new technologies as a student. I had decided to focus on learning and decided not to stay connected on the internet while I am in the learning session. On the second day of the event after the learning was over, I noticed lots of notification from my friend on my various social media handle. He had connected with me on Twitter, Facebook, Google+, LinkedIn, YouTube as well SMS, WhatsApp on the phone, Skype messages and not to forget with a few emails. I right away called him up. The problem was very unique – let us hear the problem in his own words. “Pinal – we are in big trouble we are not able to figure out what is going on. Our product details table is continuously loosing rows. Lots of rows have disappeared since morning and we are unable to find why the rows are getting deleted. We have made sure that there is no DELETE command executed on the table as well. The matter of the fact, we have removed every single place the code which is referencing the table. We have done so many crazy things out of desperation but no luck. The rows are continuously deleted in a random pattern. Do you think we have problems with intrusion or virus?” After describing the problems he had pasted few rants about why I was not available during the day. I think it will be not smart to post those exact words here (due to many reasons). Well, my immediate reaction was to get online with him. His problem was unique to him and his team was all out to fix the issue since morning. As he said he has done quite a lot out in desperation. I started asking questions from audit, policy management and profiling the data. Very soon I realize that I think this problem was not as advanced as it looked. There was no intrusion, SQL Injection or virus issue. Well, long story short first - It was a very simple issue of foreign key created with ON UPDATE CASCADE and ON DELETE CASCADE.  CASCADE allows deletions or updates of key values to cascade through the tables defined to have foreign key relationships that can be traced back to the table on which the modification is performed. ON DELETE CASCADE specifies that if an attempt is made to delete a row with a key referenced by foreign keys in existing rows in other tables, all rows containing those foreign keys are also deleted. ON UPDATE CASCADE specifies that if an attempt is made to update a key value in a row, where the key value is referenced by foreign keys in existing rows in other tables, all of the foreign key values are also updated to the new value specified for the key. (Reference: BOL) In simple words – due to ON DELETE CASCASE whenever is specified when the data from Table A is deleted and if it is referenced in another table using foreign key it will be deleted as well. In my friend’s case, they had two tables, Products and ProductDetails. They had created foreign key referential integrity of the product id between the table. Now the as fall was up they were updating their catalogue. When they were updating the catalogue they were deleting products which are no more available. As the changes were cascading the corresponding rows were also deleted from another table. This is CORRECT. The matter of the fact, there is no error or anything and SQL Server is behaving how it should be behaving. The problem was in the understanding and inappropriate implementations of business logic.  What they needed was Product Master Table, Current Product Catalogue, and Product Order Details History tables. However, they were using only two tables and without proper understanding the relation between them was build using foreign keys. If there were only two table, they should have used soft delete which will not actually delete the record but just hide it from the original product table. This workaround could have got them saved from cascading delete issues. I will be writing a detailed post on the design implications etc in my future post as in above three lines I cannot cover every issue related to designing and it is also not the scope of the blog post. More about designing in future blog posts. Once they learn their mistake, they were happy as there was no intrusion but trust me sometime we are our own enemy and this is a great example of it. In tomorrow’s blog post we will go over their code and workarounds. Feel free to share your opinions, experiences and comments.
