Oracle Retail Mobile POS offers wide ranging cost and efficiency benefits by allowing staff resource to be used more effectively whilst also reducing spend associated with fixed POS solutions. For retailers utilising Oracle Retail Stores Solutions, additional benefits can be realised. Oracle Retail Mobile POS works with these solutions to allow store personnel to check in-store inventory, access product information and specifications, and perform tasks such as the printing or emailing of receipts and the activation of gift cards.  As Oracle Retail Mobile POS is an extension of Oracle Retail Point-of-Service, retailers can benefit from seamless integration with existing systems, simple upgrade procedures and seamless delivery across the business. However, the solution’s scalable and flexible architecture also supports multiple mobile operators and systems, so retailers are not locked into particular vendors. As well as being popular with retailers, Mobile POS has also proved to be well liked by consumers as it facilitates improved customer service levels. Retail staff are able to spend more time with consumers on the shop floor, access requested inventory information, and perform tasks that would traditionally have needed to be completed at a fixed cash register. Additional information can be accessed on Oracle Retail Point-of-Service or read the press announcement Oracle Introduces Mobile Point-of-Service for Retailers.

• Multitenant Design for SQL Azure: White Paper Available

  - by Herve Roggero

  Cloud computing is about scaling out all your application tiers, from web application to the database layer. In fact, the whole promise of Azure is to pay for just what you need. You need more IIS servers? No problemo... just spin another web server. You expect to double your storage needs for Azure Tables? No problemo; you are covered there too... just pay for your storage needs. But what about the database tier, SQL Azure? How do you add new databases easily, and transparently, so that your application simply uses more of SQL Azure if its needs to? Without changing a single line of code? And what if you need to scale back down? Welcome to the world of database scalability. There are many terms that describe database scalability, including data federation, multitenant designs, and even NoSQL depending on the technical solution you are implementing.  Because SQL Azure is a transactional database system, NoSQL is not really an option. However data federation and multitenant designs offer some very interesting scalability options that are worth considering. Data federation, a feature of SQL Azure that will be offered in the future, offers very interesting capabilities available natively on the SQL Azure platform. More to come in a few weeks... Multitenant designs on the other hand are design practices and technologies designed to help you reach flexible scalability options not available otherwise. The first incarnation of such a method was made available on CodePlex as an open source project (http://enzosqlshard.codeplex.com).  This project was an attempt to provide a sharding library for educational purposes.  All that sounds really cool... and really esoteric... almost a form of database "voodoo"... However after being on multiple Azure projects I am starting to see a real need. Customers want to be able to free themselves from the database tier, so that if they have 10 new customers tomorrow, all they need to do is add 2 more SQL Azure instances. It's that simple. How you achieve this, and suggested application design guidelines, are available in a white paper I just published.  The white paper offers two primary sections. The first section describes the business and technical problem at hand, and how to classify it according to specific design patterns. For example, I discuss compressed shards through schema separation. The second section offers a method for addressing the needs of a multitenant design using a new library, the big bother of the codeplex project mentioned previously (that I created earlier this year), complete with management interface and such. A Beta of this platform will be made available within weeks; as soon as the documentation will be ready.   I would like to ask you to drop me a quick email at [email protected] if you are going to download the white paper. It's not required, but it would help me get in touch with you for feedback.  You can download this white paper here:   http://www.bluesyntax.net/files/EnzoFramework.pdf . Thank you, and I am looking for feedback, thoughts and implementation opportunities.

• How and when to ask for a pay raise?

  - by Nico

  When should one ask for a pay raise? Will I know when the time is right for a pay raise? or should I just think "I deserve a pay raise for X and Y." When would be a moment to ask for a pay grade? For instance, if you are in a company that outsources to others, could it be the right moment to ask when they move you to a different physical workplace? Maybe a few weeks/months after you started working as a consultant at the client? Should you ask for one after engaging new technologies or something you've never worked with before? In short, should you ask for a raise for a "business motive" (they move you, they assign you new responsibilities), a "professional motive" (you are required to learn new languages or technologies), or a "personal motive" (you are having twins, your mother died and you need to arrange the funeral), or are all of the above potentially valid motives? How should one ask for it? Asking for a pay raise can be difficult for some people, how you deal with this? Do you just walk up to your manager and tell him "I need more money", "I think I deserve a pay raise"? Do you suggest you might have other offers on the table? Couldn't this be counterproductive if you actually really want to stay in the company you are in (because you like the environment, made a few friends, and like all the features they give you besides your pay grade; say: free sodas, parties, after-offices that happen pretty often, a ps3 you can grab when you are tired or want to chill out, courses, english classes, football games, etc, etc. [these would be my reasons not to leave]). I mean, how would you ask for a pay raise, effectively, but without pretending to threaten to leave the company if you don't get it? Because you don't actually want to. How would you deal with their answer? If they tell you they don't think you deserve a raise, would you ask for their reasons, would you get furious and trash the room? If they give you their reasons why they think you don't deserve a pay raise yet, would you discuss this with them or just take their opinion as factual? What if they ask you how much more you think you deserve to be being paid? Should you have thought this before-hand, or expect them to set the new grade? If they do agree to a pay raise, should you expect extra work to be thrown your way, or should everything remain the same, except your pay grade?

• Why wearing Jeans is considered unprofessional?

  - by Gopinath

  When I started my career 9 years ago I use to wear casual wear to office – Jeans & T-Shirts all the 5 days. The environment at workplace during those days encouraged me to be casual and many of my colleagues use to come in Jeans. We just started our career those days it was perfectly fine to be in casual. As I grow up in the ladder, I started feeling the discomfort of wearing Jeans at work. During clients visits, senior managers meetings and consultations I was an odd man in the crowd as the rest of them are in formals. In order to be one among the professionals I’m forced change my dressing style and start wearing formals. But  the question of “Why wearing jeans to workplace is considered as unprofessional?” use in linger in my mind till today. I got the answer to my question from a discussion thread on Quora When they were invented, jeans were associated with blue-collar work. They were meant to get muddy and gross and take lots of abuse without falling apart, even if you wore the same pair every day. The people who bought them were the ones whose lives required durable clothing. And another commenter says… A professional image is critical to cementing business relationships, and part of that is, for right or wrong, how you dress. Jeans are typically associated with "kicking back", relaxation, leisure, informality,  and even a slightly rebellious flavor. The style and condition of the jeans are a consideration, as we often wear jeans into advanced states of being worn down, with tearing, etc.. that we generally do not do with other clothing items. I agree with this theory even though it may be centuries old. If you want to look like a professional and treated like a professional it’s better to be dress up in formals. These days I make a point to be in formals at workplace. Not everyone is Steve Jobs to wear a Jean & Turtle Neck T-shirt  right? CC Image credit flickr/exey

• Why a graduate program in South Africa?

  - by anca.rosu

  South Africa, like many other countries, is desperate for skills. Good, solid, technical skills – together with a get-up-and-go attitude – and the desire to work for a world-class organization that is leading the way! In addition, we have made a commitment in South Africa that we need to transform our organization and develop and empower Black individuals who historically have not had the opportunity to participate in the global economy. It is through this investment in our country's people that we contribute to the development of a nation capable of competing on the global stage. This makes for an exciting recipe! We have: Plenty of young and talented individuals who are eager to get stuck in and learn. Formal, recognized qualifications that form the basis for further development. A huge big global organization – Oracle – that is committed to developing these graduates and giving them an opportunity that is out of this world! Mix the above ‘ingredients’ together Tackle and remove potential “lumps & bumps” along the way as we learn and grow together Nurture and care for each other in a warm but tough environment What have we achieved? In most cases, the outcome is an awesome bunch of new talent that is well equipped to face the IT world. Where we have the opportunity and suitable headcount available to employ these graduates at Oracle we snap them up – alternatively our business partners and customers are always eager to recruit Oracle graduates into their organizations! These individuals go through real-life work place experience whilst at Oracle. In some cases they get to travel internationally. The excitement and buzz gets into their system and their blood becomes truly RED! Oracle RED! This is valuable talent and expertise to have in our eco-system and it’s an exciting program to be a part of not only as a graduate but as an Oracle employee too!   If you have any questions related to this article feel free to contact  [email protected].  You can find our job opportunities via http://campus.oracle.com.

• Failing report subscriptions

  - by DavidWimbush

  We had an interesting problem while I was on holiday. (Why doesn't this stuff ever happen when I'm there?) The sysadmin upgraded our Exchange server to Exchange 2010 and everone's subscriptions stopped. My Subscriptions showed an error message saying that the email address of one of the recipients is invalid. When you create a subscription, Reporting puts your Windows user name into the To field and most users have no permissions to edit it. By default, Reporting leaves it up to exchange to resolve that into an email address. This only works if Exchange is set up to translate aliases or 'short names' into email addresses. It turns out this leaves Exchange open to being used as a relay so it is disabled out of the box. You now have three options: Open up Exchange. That would be bad. Give all Reporting users the ability to edit the To field in a subscription. a) They shouldn't have to, it should just work. b) They don't really have any business subscribing anyone but themselves. Fix the report server to add the domain. This looks like the right choice and it works for us. See below for details. Pre-requisites: A single email domain name. A clear relationship between the Windows user name and the email address. eg. If the user name is joebloggs, then joebloggs@domainname needs to be the email address or an alias of it. Warning: Saving changes to the rsreportserver.config file will restart the Report Server service which effectively takes Reporting down for around 30 seconds. Time your action accordingly. Edit the file rsreportserver.config (most probably in the folder ..\Program Files[ (x86)]\Microsoft SQL Server\MSRS10_50[.instancename]\Reporting Services\ReportServer). There's a setting called DefaultHostName which is empty by default. Enter your email domain name without the leading '@'. Save the file. This domain name will be appended to any destination addresses that don't have a domain name of their own.

• Enterprise 2.0 Conference recap

  - by kellsey.ruppel

  We had a great week in Boston attending the Enterprise 2.0 Conference. We learned a lot from industry thought leaders and had a chance to speak with a lot of different folks about social and collaboration technologies and trends.  Of all the conferences we attend, this one definitely has a different “feel”. It seems like the attendees are younger, they dress hipper, and there is much more livelihood all around. A few of the sessions addressed this, as the "millenials" or Generation Y, have been using Web 2.0 tools, such as Facebook and Twitter for many years now, and as they are entering the workforce they are expecting similar tools to be a part of how they accomplish their job tasks. It's important to note that it's not just Millenials that are expecting these technologies, as workers young and old alike benefit from social and collaboration tools. I’ve highlighted some of the takeaways I had, as well as a reaction from John Brunswick, who helped us in staffing the booth. Giving your employees choices is empowering, but if there is no course of action or plan, it’s useless. There is no such thing as collaboration without a goal. In a few years, social will become a feature in the “platform”, a component of collaboration. Social will become part of the norm – just like email is expected when you start a job at a company, Social will be too. 1 in 3 of your employees are using tools your company doesn't sanction (how scary is this?!) 25,000 pieces of content are created every second. Context is king. Social tools help us navigate and manage the complexities we face with information overload. We need to design products for the way people work. Consumerization of the enterprise - bringing social tools like Facebook to the organization. From John Brunswick: "The conference had solid attendance, standing as a testament to organizations making a concerted effort to understand what social tools exist to support their businesses.  Many vendors were narrowly focused and people we pleasantly surprised at the breadth of capability provided by Oracle WebCenter.  People seemed to feel that it just made sense that social technology provides the most benefit when presented in the context of key business data." Did you attend the conference? What were some of your key takeaways?

• Restrict number of characters to be typed for af:autoSuggestBehavior

  - by Arunkumar Ramamoorthy

  When using AutoSuggestBehavior for a UI Component, the auto suggest list is displayed as soon as the user starts typing in the field. In this article, we will find how to restrict the autosuggest list to be displayed till the user types in couple of characters. This would be more useful in the low latency networks and also the autosuggest list is bigger. We could display a static message to let the user know that they need to type in more characters to get a list for picking a value from. Final output we would expect is like the below image Lets see how we can implement this. Assuming we have an input text for the users to enter the country name and an autosuggest behavior is added to it. <af:inputText label="Country" id="it1"> <af:autoSuggestBehavior /> </af:inputText> Also, assuming we have a VO (we'll name it as CountryView for this example), with a view criteria to filter out the VO based on the bind variable passed. Now, we would generate View Impl class from the java node (including bind variables) and then expose the setter method of the bind variable to client interface. In the View layer, we would create a tree binding for the VO and the method binding for the setter method of the bind variable exposed above, in the pagedef file As we've already added an input text and an autosuggestbehavior for the test, we would not need to build the suggested items for the autosuggest list.Let us add a method in the backing bean to return us List of select items to be bound to the autosuggest list. padding: 5px; background-color: #fbfbfb; min-height: 40px; width: 544px; height: 168px; overflow: auto;"> public List onSuggest(String searchTerm) { ArrayList<SelectItem> selectItems = new ArrayList<SelectItem>(); if(searchTerm.length()>1) { //get access to the binding context and binding container at runtime BindingContext bctx = BindingContext.getCurrent(); BindingContainer bindings = bctx.getCurrentBindingsEntry(); //set the bind variable value that is used to filter the View Object //query of the suggest list. The View Object instance has a View //Criteria assigned OperationBinding setVariable = (OperationBinding) bindings.get("setBind_CountryName"); setVariable.getParamsMap().put("value", searchTerm); setVariable.execute(); //the data in the suggest list is queried by a tree binding. JUCtrlHierBinding hierBinding = (JUCtrlHierBinding) bindings.get("CountryView1"); //re-query the list based on the new bind variable values hierBinding.executeQuery(); //The rangeSet, the list of queries entries, is of type //JUCtrlValueBndingRef. List<JUCtrlValueBindingRef> displayDataList = hierBinding.getRangeSet(); for (JUCtrlValueBindingRef displayData : displayDataList){ Row rw = displayData.getRow(); //populate the SelectItem list selectItems.add(new SelectItem( (String)rw.getAttribute("Name"), (String)rw.getAttribute("Name"))); } } else{ SelectItem a = new SelectItem("","Type in two or more characters..","",true); selectItems.add(a); } return selectItems; } So, what we are doing in the above method is, to check the length of the search term and if it is more than 1 (i.e 2 or more characters), the return the actual suggest list. Otherwise, create a read only select item new SelectItem("","Type in two or more characters..","",true); and add it to the list of suggested items to be displayed. The last parameter for the SelectItem (boolean) is to make it as readOnly, so that users would not be able to select this static message from the displayed list. Finally, bind this method to the input text's autosuggestbehavior's suggestedItems property. <af:inputText label="Country" id="it1"> <af:autoSuggestBehavior suggestedItems="#{AutoSuggestBean.onSuggest}"/> </af:inputText>

• Flow-Design Cheat Sheet &ndash; Part II, Translation

  - by Ralf Westphal

  In my previous post I summarized the notation for Flow-Design (FD) diagrams. Now is the time to show you how to translate those diagrams into code. Hopefully you feel how different this is from UML. UML leaves you alone with your sequence diagram or component diagram or activity diagram. They leave it to you how to translate your elaborate design into code. Or maybe UML thinks it´s so easy no further explanations are needed? I don´t know. I just know that, as soon as people stop designing with UML and start coding, things end up to be very different from the design. And that´s bad. That degrades graphical designs to just time waste on paper (or some designer). I even believe that´s the reason why most programmers view textual source code as the only and single source of truth. Design and code usually do not match. FD is trying to change that. It wants to make true design a first class method in every developers toolchest. For that the first prerequisite is to be able to easily translate any design into code. Mechanically, without thinking. Even a compiler could do it :-) (More of that in some other article.) Translating to Methods The first translation I want to show you is for small designs. When you start using FD you should translate your diagrams like this. Functional units become methods. That´s it. An input-pin becomes a method parameter, an output-pin becomes a return value: The above is a part. But a board can be translated likewise and calls the nested FUs in order: In any case be sure to keep the board method clear of any and all business logic. It should not contain any control structures like if, switch, or a loop. Boards do just one thing: calling nested functional units in proper sequence. What about multiple input-pins? Try to avoid them. Replace them with a join returning a tuple: What about multiple output-pins? Try to avoid them. Or return a tuple. Or use out-parameters: But as I said, this simple translation is for simple designs only. Splits and joins are easily done with method translation: All pretty straightforward, isn´t it. But what about wires, named pins, entry points, explicit dependencies? I suggest you don´t use this kind of translation when your designs need these features. Translating to methods is for small scale designs like you might do once you´re working on the implementation of a part of a larger design. Or maybe for a code kata you´re doing in your local coding dojo. Instead of doing TDD try doing FD and translate your design into methods. You´ll see that way it´s much easier to work collaboratively on designs, remember them more easily, keep them clean, and lessen the need for refactoring. Translating to Events [coming soon]

• Selectively Exposing Functionallity in .Net

  - by David V. Corbin

  Any developer should be aware of the principles of encapsulation, cross-tier isolation, and cross-functional separation of concerns. However, it seems the few take the time to consider the adage of "minimal yet complete"1 when developing the software. Consider the exposure of "business objects" to the user interface. Some common situations occur: Accessing a given element requires a compound set of calls that do not "make sense" to the User Interface. More information than absolutely required is exposed to the user interface It would be much cleaner if a custom interface was provided that exposed exactly (and only) the information that is required by the consumer. Achieving this using conventional techniques would require the creation (and maintenance!) of custom classes to filter and transpose the information into the ideal format. Determining the ROI on this approach can be very difficult to ascertain, and as a result it is often ignored completely. There is another approach, which is largely made practical by virtual of the Action and Func delegates. From a callers point of view, the following two samples can be used interchangeably:     interface ISomeInterface     {         void SampleMethod1(string param);         string SamepleMethod2(string param);     }       class ISomeInterface     {         public Action<string> SampleMethod1 {get; }         public Func<string,string> SamepleMethod2 {get; }     }   The capabilities this simple changes enable are significant (and remember it does not cange the syntax at the call site): The delegates can be initialized to directly call the proper method of any target class. The delegates can be dynamically updated based on the current state. The "interface" can NOT be cast to the concrete class (which often exposes more functionallity). This patterns By limiting the interface to the exact functionallity required, the reduced surface area will typically result in lower development, testing and maintenance costs. We are currently in the process of posting a project on CodePlex which illustrates this (and many other) techniques which have proven helpful in creating robust yet flexible solutions that are highly efficient2 and maintainable. This post will be updated as soon as the project is published. 1) Credit: Scott  Meyers, Effective C++, Addison-Wesley 1992 2) For those who read my previous post on performance it should be noted that the use of delegates is on the same order of magnitude (actually a tiny amount faster) as conventional interfaces.

• Isis Finally Rolls Out

  - by David Dorf

  Google has rolled their wallet out for several chains; I see the NFC readers in Walgreen's when I'm sent their for milk.  But Isis has been relatively quiet until now.  As of last week they have finally launched in their two test cities: Austin, and Salt Lake City.  Below are the supported carriers and phones as of now, but more phones will be added later. Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;} AT&T supports: HTC One™ X, LG Escape™, Samsung Galaxy Exhilarate™, Samsung Galaxy S® III, Samsung Galaxy Rugby Pro™ T-Mobile supports: Samsung Galaxy S® II, Samsung Galaxy S® III, Samsung Galaxy S® Relay 4G Verizon supports: Droid Incredible 4G LTE. Of course iPhone owners have no wallet since Apple didn't included an NFC chip. To start using Isis, you have to take your NFC-capable phone to your carrier's store to get the SIM replaced with a more sophisticated one that has a secure element configured for Isis.  The "secure element" is the cryptographic logic that secures mobile payments.  Carriers like the secure element in the SIM while non-carriers (like Google) prefer the secure element in the phone's electronics. (I'm not entirely sure if you could support both Isis and Google Wallet on the same phone.  Anybody know?) Then you can download the Isis app from Google Play and load your cards.  Most credit cards are supported, and there's a process to verify the credit cards are valid.  Then you can select from the list of participating retailers to "follow."  Selecting a retailer allows that retailer to give you offers via the app. The app is well done and easy to use.  You can select a default payment type and also switch between them easily.  When the phone is tapped on the reader, there are two exchanges of information.  The payment information is transferred, and then the Isis "SmartTap" information which includes optional loyalty number and digital coupons.  Of course the value of mobile wallets comes from the ease of handling all three data types (i.e. payment, loyalty, offers). There are several advertisements for Isis running now, and my favorite is below.

• Too Clever for My Own Good

  - by AjarnMark

  Yesterday I caught myself being a little too clever for my own good with some ASP.NET code.  It seems that I have forgotten some of my good old classic HTML and JavaScript skills, and become too dependent on the .NET Framework and WebControls to do the work for me.  Here’s the scenario… In order to improve the User Interface and better communicate to the user when something is happening that they need to wait for, we have started to modify some of our larger (slower) pages to display messages like Processing… or Reloading… while they are cycling through a postback.  (Yes, I understand this could be improved by using AJAX / Callbacks and so on, but even then, you need to let your user know that they need to wait for that section to be re-rendered, so for the moment these pages will continue to use good ol’ Postbacks.)  It’s a very simple trick, really.  All I want to do is when some control triggers a postback, first run a little client-side JavaScript to hide the main contents of the page (such as a GridView) and display the appropriate message.  This lets the user know, “Hey, we’re doing something, don’t click another link or scroll and try to take action right now.” The first places I hooked this up were easy.  Most common cause of a postback:  Buttons.  And when you’re writing the markup or declarative code for an ASP:Button control, there is the handy OnClientClick property which is designed for just this purpose…to run client-side JavaScript before the postback occurs.  This is distinguished from the OnClick property which tells the control what Server-side code to run.  Great!  Done!  Easy! But then there are other controls like DropDownLists and CheckBoxes that we use on our pages with the AutoPostback=True setting which cause postbacks.  And these don’t have OnClientClick or OnClientSelectedIndexChanged events.  So I started getting creative, using an ASP:CustomValidator control in conjunction with setting the CausesValidation and ValidationGroup settings on these controls, which basically caused the action on the control to fire the Custom Validator, which was defined with a Client Side validation function which then did the hide content/show message code (and return a meaningless IsValid setting).  This also caused me to define a different ValidationGroup setting for my real data entry validator controls so that I could control them separately and only have them fire when I really wanted validation, and not just my show/hide trick. For a little while I was pretty proud of myself for coming up with this clever approach to get around what I considered to be a serious oversight on the DropDownList and CheckBox controls declarative syntax.  Then, in the midst of my smugness, just as I was about to commit my changes to the source code repository, it dawned on me that there is a much simpler and much more appropriate way to accomplish this.  All that I really needed to do was to put in my server-side code (I used the Page_Init section) a call to MyControl.Attributes.Add(“onClick”, “myJavaScriptFunctionName()”) for the checkboxes, and for the DropDownLists (which become select tags) use “onChange” instead of “onClick”.  This is exactly the type of thing that the Attributes collection is there for…so you can add attributes to be rendered with the control that you would have otherwise stuck right into the HTML markup if you had been doing this by hand in the first place. Ugh!  A few hours wasted on clever tricks that I ended up completely removing, but I did learn a lot more about custom validators and validation groups in the process.  And got a good reminder that all that stuff (HTML, JavaScript, and CSS) I learned back when I wrote classic ASP pages is still valuable today.  Oh, and one more thing…don’t get lulled into too much reliance on the the whiz-bang tool to do it for you.  After all, WebControls are just another layer of abstraction, and sometimes you need to dig down through the layers and get a little closer to the native language.

• What is new in Oracle SOA Suite 11g R1 PS6? by Shanny Anoep

  - by JuergenKress

  Oracle has released a new version 11.1.1.7.0 for their Oracle Fusion Middleware product line. This version includes Patch Set #6 (PS6) for Oracle SOA Suite 11g R1, with a big list of improvements and fixes for each component in that suite. In this post we will highlight some of the interesting updates with regards to troubleshooting, performance, reliability and scalability. Infrastructure/Purging scripts Database growth is a common problem for large-scale Oracle SOA Suite deployments. Oracle already provides multiple purging strategies for the SOA Suite runtime database. This patch set includes two new scripts for purging most of the runtime data: Table Recreation Script (TRS): This script can be used to reclaim as much database space as possible, while still retaining the open instances. It can be used as a corrective action for databases that grew excessively, for example when purging was not performed at all. This should be used as a single corrective action only; the script does not replace the normal purging scripts. Truncate script: Remove all records from the SOA Suite runtime tables without dropping the tables. This script can be used for cloning SOA Suite environments without copying the instance data, or for recreating test scenarios by cleaning all the runtime data. The Oracle SOA Suite Administrator's guide contains a table with the available purging strategies. Diagnostic dumps Using WLST you could already dump diagnostic information about various components of the SOA Suite. This version adds support to retrieve more information on BPEL and Adapters from the command-line. Diagnostic dumps for BPEL New diagnostic dumps are available for BPEL to get information on thread pools, average processing time for BPEL components, and average waiting times for asynchronous instances. This information can be very useful for performance analysis or troubleshooting. With WLST this information can be retrieved from the command-line and included for monitoring or reporting.

• Agile PLM Highlights from Oracle OpenWorld 2012

  - by Kerrie Foy

  Thank you to everyone who joined us at Oracle OpenWorld this year, either in person or virtually (thanks for tweeting #oowplm)!  From customer presentations to after-hours networking opportunities, there was a lot to see and do during the entire conference. Sessions It was our pleasure to feature several customer speakers during our PLM sessions at OpenWorld from such companies as Starbucks, Coca-Cola, Facebook, Eli Lilly, and many more.  Each had a unique perspective to share and fascinating insight into how they successfully leverage Agile PLM to facilitate profitable innovation, protect brand integrity, streamline operations, manage compliance, launch faster, etc.  For example, during the Product Value Chain keynote session, CIO Chris Bedi of JDSU shared how they implemented Agile PLM to support business imperatives around rapid innovation, centralizing product information, collaboration, and eliminate the “Excel gymnastics” required to obtain global portfolio visibility. In just 120 days after implementing, JDSU employees reported significant improvements around product record management, new product introduction, engineering collaboration and more, which created a better work environment to enable critical innovation. I could write on and on about the almost 20 sessions! So to spare yourselves, please visit launch.oracle.com/?plmopenworld2012; it’s a curated selection of PLM presentations from the OpenWorld Content Catalog and available on-demand. Enjoy! Agile Innovation Management During OpenWorld, we announced an exciting new addition to the Agile PLM applications called Innovation Management that redefines the industry’s scope of product lifecycle management.  Our broad vision of complete enterprise PLM for the entire Product Value Chain already broke new ground by helping organizations extend PLM disciplines downstream by connecting product design to commercialization processes; now we are helping executives look farther upstream in the early innovation phases to ultimately close the gap between strategy and execution that so commonly nags innovation initiatives.  More on this coming soon so stay tuned! Unique Networking Opportunities  We know it can be challenging during OpenWorld to find time to productively connect and network with your industry peers, so we hosted an Agile PLM “Birds of a Feather” networking brunch for the second year in a row.  At a fine restaurant close to Moscone we hosted nine tables, each with only ten seats to encourage active conversation.  Furthermore, guests could select from a list of predetermined table topics sponsored by a specialized PLM partner to guarantee – even more so – that they were seated with like-minded company and optimizing their time at the conference.  Everyone enjoyed the opportunity to easily connect with other PLM users during OpenWorld in a more casual setting. What’s Next? Thank you again to all who joined us!  If you haven't yet, mark your calendar to join us for the next Oracle Agile PLM conference at the Value Chain Summit in San Francisco, February 4-6 in 2013!  We’ll have 40 sessions of PLM content in four tracks. Don’t miss it! You can sign up to be notified when official registration opens by visiting www.oracle.com/goto/vcs.

• SQLAuthority News – Download Whitepaper – SQL Server Analysis Services to Hive

  - by pinaldave

  The SQL Server Analysis Service is a very interesting subject and I always have enjoyed learning about it. You can read my earlier article over here. Big Data is my new interest and I have been exploring it recently. During this weekend this blog post caught my attention and I enjoyed reading it. Big Data is the next big thing. The growth is predicted to be 60% per year till 2016. There is no single solution to the growing need of the big data available in the market right now as well there is no one solution in the business intelligence eco-system available as well. However, the need of the solution is ever increasing. I am personally Klout user. You can see my Klout profile over. I do understand what Klout is trying to achieve – a single place to measure the influence of the person. However, it works a bit mysteriously. There are plenty of social media available currently in the internet world. The biggest problem all the social media faces is that everybody opens an account but hardly people logs back in. To overcome this issue and have returned visitors Klout has come up with the system where visitors can give 5/10 K+ to other users in a particular area. Looking at all the activities Klout is doing it is indeed big consumer of the Big Data as well it is early adopter of the big data and Hadoop based system.  Klout has to 1 trillion rows of data to be analyzed as well have nearly thousand terabyte warehouse. Hive the language used for Big Data supports Ad-Hoc Queries using HiveQL there are always better solutions. The alternate solution would be using SQL Server Analysis Services (SSAS) along with HiveQL. As there is no direct method to achieve there are few common workarounds already in place. A new ODBC driver from Klout has broken through the limitation and SQL Server Relation Engine can be used as an intermediate stage before SSAS. In this white paper the same solutions have been discussed in the depth. The white paper discusses following important concepts. The Klout Big Data solution Big Data Analytics based on Analysis Services Hadoop/Hive and Analysis Services integration Limitations of direct connectivity Pass-through queries to linked servers Best practices and lessons learned This white paper discussed all the important concepts which have enabled Klout to go go to the next level with all the offerings as well helped efficiency by offering a few out of the box solutions. I personally enjoy reading this white paper and I encourage all of you to do so.

• Redgate ANTS Performance Profiler

  - by Jon Canning

  Seemingly forever I've been working on a business idea, it's a REST API delivering content to mobiles, and I've never really had much idea about its performance. Yes, I have a suite of unit tests and integration tests, but these only tell me that it works, not how well it works. I was also about to embark on a major refactor, swapping the database from MongoDB to RavenDB, and was curious to see if that impacted performance at all, so I needed a profiler that supported IIS Express that I can run my integration tests against, and Google gave me:   http://www.red-gate.com/supportcenter/content/ANTS_Performance_Profiler/help/7.4/app_iise   Excellent. Following the above guide an instance of IIS Express and is launched, as is Internet Explorer. The latter eventually becomes annoying, I would like to decide whether I want a browser opened, but thankfully the guide is wrong in that it can be closed and profiling will continue. So I ran my tests, stopped profiling, and was presented with a call tree listing the endpoints called and allowing me to drill down to the source code beneath.     Although useful and fascinating this wasn't what I was expecting to see, I was after the method timings from the entire test suite. Switching Show to Methods Grid presented me with a list of my methods, with the slowest lit up in red at the top. Marvellous.     I did find that if you switch to Methods Grid before Call tree has loaded, you do not get the red warnings.   StructureMap was very busy, and next on the list was a request filter that I didn't expect to be so overworked. Highlighting it, the source code was presented to me in the bottom window with timings and a nice red indicator to show me where to look. Oh horror, that reflection hack I put in months ago, I'd forgotten all about it. It was calling Validate<T>() which in turn was resolving a validator from StructureMap. Note to self, use //TODO: when leaving smelly code lying around.     Before refactoring, remember to Save Profile Results from the File menu. Annoyingly you are not prompted to save your results when exiting, and using Save Project will only leave you thankful that you have version control and can go back in time to run your tests again.   Having implemented StructureMap’s ForGenericType, I ran my tests again and:     Win, thankyou ANTS (What does ANTS stand for BTW?)   There's definitely room in my toolbox for a profiler; what started out as idle curiosity actually solved a potential problem. When presented with a new codebase I can see enormous benefit from getting an overview of the pipeline from the call tree before drilling into the code, and as a sanity check before release it gives a little more reassurance that you've done your best, and shows you exactly where to look if you haven’t.   Next I’m going to profile a load test.

• VirtualBox image SOA Suite &amp; BPM Suite 11.1.1.6.0 & Your feedback?

  - by JuergenKress

  The integration PM team is very pleased to announce the release of a new version of our pre-configured SOA/BPM VirtualBox image for testing and evaluation. This VirtualBox appliance contains a fully configured, ready-to-use SOA/BPM/Webcenter 11.1.1.6.0 installation. All you need is to install Oracle VM VirtualBox on your desktop/laptop and import the SOA/BPM appliance and you are ready to try out SOA Suite and BPM Suite -- no installation and configuration required! The following software is installed in this VritualBox image: Oracle Enterprise Linux (64-bit) EL 5 Update 5 Oracle XE Database 11.2.0 Oracle SOA Suite 11.1.1.6.0 (includes Service Bus) Oracle BPM Suite 11.1.1.6.0 Oracle Webcenter Content (Enterprise Content Management) 11.1.1.6.0 Oracle Webcenter Suite 11.1.1.6.0 Oracle JDeveloper 11.1.1.6.0 JRockit R28.2.0-79-146777-1.6.0_29s Sun Java SDK 1.6.0_29-b11 If you want to try it out, please go to the Pre-built Virtual Machine for SOA Suite and BPM Suite 11g OTN page for detailed instructions on downloading and importing the VirtualBox image. Jon Petter Hjulstad published the first impression at his blog Twitter & LinkedIn We have been waiting for the new VirtualBox Image for a long time, and finally it is here. The appliance has improved in many ways since last release, so it has been worth waiting for. Both the appliance itself and the documentation is excellent. It is evident that Oracle has listened to feedback on the previous release, and I think the developer VMs are useful. Especially the adoption of new patchsets and versions (ex when 12c will be available) will gain a lot from quick getting hands-on experiences. This VirtualBox appliance is a multipurpose image which can be used in different domain configurations. The image has a number of pre-configured domains that you can use depending on your need. The image can be set up so that it requires use of as few resources as possible, you can for instance easily disable B2B if you do not need it, or you can shut down the desktop console and save 600MB. It is important to say that this image is not for production purposes.

• So, what&rsquo;s your blog URL?

  - by johndoucette

  Asked by many of my colleagues often enough, I decided to take the plunge and begin blogging. After many attempts to start and long discussions about what I should write about, I decided to give my “buddies” a series of lessons and tidbits to help them understand what it takes to manage a software development project in the real world. Stories of success and failure to keep hope alive. I am formally trained as a developer (BS/CS) and have scattered my code throughout the matrix since 1985 (officially working for the man). As I moved from job-to-job over my career, I have had good managers, bad ones, and ones who were – well, just sitting in the corner office. It wasn't until I began the transition and commitment to the role of project management that I began to take real software development management seriously. A boss once told me “put down the code. Start managing the people and process.” That was a scary time in my career. I loved solving really cool problems with a blank sheet of paper. It was an adrenaline rush to get an opportunity to start from scratch and write an application solution people would actually use and help them in their work/business. I felt that moving into “management” would remove me from the thrill and ownership I felt as a developer. It was a hard step to take, and one which I believe is hard for any developer. Well, I am here to help you through this transition. For those of you wanting to read my stories or learn about the tools and techniques I use on a daily basis, you too might just learn something you would have never thought of as an architect/developer. I am currently a Sr. Consultant at Magenic with the Boston branch office and primarily work with clients in the New England area. I am typically engaged as the lead project manager on our engagements, but also perform Application Lifecycle Management (ALM) assessments for development organizations as well as augment the Technical Evangelists for Microsoft and perform many Team Foundation Server (TFS) demos, installs and “get started” engagements. I have spoken at the New England Code Camp, our most recent CodeMastery event in Boston, and have written several whitepapers.   I am looking forward to helping you “Put down the code.” John Doucette

• Windows Desktop Virtualization Gets Easier

  - by andrewbrust

  This past Thursday, Microsoft announced that Windows (7) Virtual PC (WVPC) and its XP Mode feature would no longer require hardware assisted virtualization (HAV).  That means any PC running Windows 7 Pro, or higher, can now run this software.  And that’s a great thing because, as I noted in a post almost five month ago, determining whether a given PC you might be planning to buy actually offers HAV can be extremely difficult.  That meant even dedicated, sophisticated PC users, with a budget for new hardware, might be blocked from using this technology.  And that was just plain silly. One of the features offered by WVPC, and utilized heavily by XP Mode, is the concept of virtual applications: apps within a guest VM that can actually run within the host’s desktop environment.  I find this feature so powerful that my February Redmond Review column entertained the notion of a future version of Windows that runs all applications in this manner. The elimination of the HAV requirement for XP Mode and WVPC was just one of many virtualization-related announcements Microsoft made on Thursday.  And, interestingly, most of the others were also desktop-related, rather than server-related.  This is a welcome change from the multi-year period in which Microsoft enhanced its server virtualization lineup (in Hyper-V) and let the desktop platform fester.  Microsoft now seems to understand desktop virtualization is in high-demand and strengthens the Windows franchise.  As I explained in the column, even cloud computing can have a desktop spin if desktop virtualization is part of the equation. One company that knows this well is Citrix, and a closer alliance between Microsoft and Citrix was one of the many announcements from Thursday.  In fact, there’s a whole Web site dedicated to the alliance at http://www.citrixandmicrosoft.com/. I’d love to see virtual applications and entire virtual desktops offered as Azure-branded services.  This could allow me to run, for example, the full Office client on a variety of desktops I might use, and for large organizations it could easily reduce the expense, burden and duration of the deployment cycle for new versions of Office.  Business Intelligence providers, including my own firm, twentysix New York, would find great relief in enabling their customers to run the newest version of Excel, with the latest BI capabilities, instead of having to wait the requisite two to three years it takes for many Fortune 500 customers to upgrade. Microsoft should do more, and faster.  WVPC still does not support 64-bit guest images, even on 64-bit hosts.  That needs to be fixed.  File access from the guest to the host needs to be improved (right now, it’s done through Terminal Services/Remote Desktop file sharing, and it’s slow) and VM load times need to be significantly reduced before virtualized apps can become the norm.  (I suppose the advance of solid state drive technology will help there.) I do think these improvements will come, because Microsoft is focused on the virtual desktop now.  And that’s a smart focus to have.

• 302: this blog will be closed

  - by preishuber

  After nearly 7 years I will discontinue blogging on this site. My resources are limited. You can reach my German blog which is used to support my customers. Looking back to a long an interesting journey ASP.NET by ScottGu That was the reason to attend this site and support Microsoft as much as I can. For that I was honored as ASP.NET MVP- thanks again. Meet Scoot several times. Great guy! Forums I have left NNTP forums a few years ago and now Microsoft closed it- It was my idea ;-) AJAX Was the wrong way- JQuery won the game IIS7 That is really a great plattform and the IIS team rules. I am sad that is so silent around that topic. ASP.NET after 2.0 Is no longer my world. I love ASP.NET and ASP.NET Server controls. I hate the discussion about how to follow the holy rules of MVC. Microsoft have dropped the goal to bring ASP.NET to #1 and accepted PHP is it. Facebook & Twittering Microblogging takes over a part of the blogging business. Shorter faster cheaper- or as SteveB mentioned - do more with less. Google Google is taking over the web. I am using Bing every time as I can but Google have more options. Sorry Microsoft you will loose that game. Apple That is not the biggest problem of Microsoft. the Ixxx takes over a small part but big money of the market, but the customers are not strongly linked. New wave new hype- Game over Apple. Silverlight My new home. I can reuse a lot of my skills and love the possibilitys. Silverligth will passing WPF-and strike Flash Windows phone 7 Also my skills fit. I just will use it for fun. I am not really satisfied about what I have heard from MIX. Guys from Redmond, I am sad to say you have been the best Smartphone OS and lost everything. The ADO vNext Story That will be the next mystic point. WCF, REST, JSON, ATOM and now OData. Nothing about SQL commands. LINQ, ORM is also not the final solution for multilayered disconnected async scenarios. Personally I prefere the OData idea and dislike the Swiss Army Knife (German Eierlegende Wollmilchsau) WCF. I am still in INETA Speakers board and I am glad to come to your user group. In all other cases you can hire me over ppedv AG. Good by and have good live.

• What's wrong with this turn to face algorithm?

  - by Chan

  I implement a torpedo object that chases a rotating planet. Specifically, it will turn toward the planet each update. Initially my implement was: void move() { vector3<float> to_target = target - get_position(); to_target.normalize(); position += (to_target * speed); } which works perfectly for torpedo that is a solid sphere. Now my torpedo is actually a model, which has a forward vector, so using this method looks odd because it doesn't actually turn toward but jump toward. So I revised it a bit to get, double get_rotation_angle(vector3<float> u, vector3<float> v) const { u.normalize(); v.normalize(); double cosine_theta = u.dot(v); // domain of arccosine is [-1, 1] if (cosine_theta > 1) { cosine_theta = 1; } if (cosine_theta < -1) { cosine_theta = -1; } return math3d::to_degree(acos(cosine_theta)); } vector3<float> get_rotation_axis(vector3<float> u, vector3<float> v) const { u.normalize(); v.normalize(); // fix linear case if (u == v || u == -v) { v[0] += 0.05; v[1] += 0.0; v[2] += 0.05; v.normalize(); } vector3<float> axis = u.cross(v); return axis.normal(); } void turn_to_face() { vector3<float> to_target = (target - position); vector3<float> axis = get_rotation_axis(get_forward(), to_target); double angle = get_rotation_angle(get_forward(), to_target); double distance = math3d::distance(position, target); gl_matrix_mode(GL_MODELVIEW); gl_push_matrix(); { gl_load_identity(); gl_translate_f(position.get_x(), position.get_y(), position.get_z()); gl_rotate_f(angle, axis.get_x(), axis.get_y(), axis.get_z()); gl_get_float_v(GL_MODELVIEW_MATRIX, OM); } gl_pop_matrix(); move(); } void move() { vector3<float> to_target = target - get_position(); to_target.normalize(); position += (get_forward() * speed); } The logic is simple, I find the rotation axis by cross product, the angle to rotate by dot product, then turn toward the target position each update. Unfortunately, it looks extremely odds since the rotation happens too fast that it always turns back and forth. The forward vector for torpedo is from the ModelView matrix, the third column A: MODELVIEW MATRIX -------------------------------------------------- R U A T -------------------------------------------------- 1 0 0 0 0 1 0 0 0 0 1 0 0 0 0 1 -------------------------------------------------- Any suggestion or idea would be greatly appreciated.
