  • Red Gate's on the road in 2012 - Will you catch us?

    - by RedAndTheCommunity
    Annabel Bradford, our Communities and Events Manager, tells all about her experience of our 1st SQL Saturday of the year. The first stop this year was SQL Saturday #104 Colorado Springs, back in early January. I made the trip across from the UK just for this SQL Saturday event, and I'm so glad I did. I picked up Max from Red Gate's Pasadena office and we flew into Colorado Springs airport late on Friday evening to be greeted by freezing temperatures, which was quite a shock after the California sunshine. Rising before the sun, we arrived at Mr Biggs, the venue for the event, in the darkness. It was great to see so many smiling attendees so bright and early on a Saturday morning. Everyone was eager to learn more about SQL Server, and hundreds of people came and chatted with us at the table, saw demos and learnt more about Red Gate tools. The event highlights for the attendees were definitely the unlimited lazer quest, bowling and pool available during the break times. For Max, Grant Fritchey and I on the Red Gate table, the highlights have to be meeting customers and getting the opportunity to meet attendees who'd heard of, but wanted to know more about, Red Gate. We were delighted to hear lots of valuable feedback that we took back to share with the team. As a thank you for sharing insights about their work lives and how they use SQL Server and Red Gate tools, attendees are able to take away Red Gate SQL Server books. We aim to have a range of titles available when we exhibit, so that attendees can choose a book that's going to be most interesting to them, and that they can use as a reference back at the office. Every time I meet a Red Gate user or a member of the SQL community, I'm always overwhelmed by the enthusiasm they have for their industry. Everyone who gives up their time to learn more about their job should be rewarded, and at Red Gate we like to do just that. Red Gate has long supported the SQL community through sponsorship to facilitate user group meetings and community events, but it's only though face-to-face contact that we really get a chance to see the impact of our support. I hope we'll have the chance to see you on the road at some point this year. We'll be at a range of events, including free SQL Saturdays, one day free events 'the Red Gate way', two-day Rallys, and full-week conferences. Next stop is SQL Saturday #109 Silicon Valley on March 3rd where you'll meet Jeff and Arneh, two of our US-based SQL team members. Be sure to ask them any questions you've got about the Red Gate tools, as these guys will be delighted to hear your questions, show you the options, and will make a note of your feedback to send through to the development team. Until the next time. Happy learning! Annabel                         Grant, Max and Annabel at SQL Saturday #104 Colorado Springs

  • Why SQL Developer Rocks for the Advanced User Too

    - by thatjeffsmith
    While SQL Developer may be ‘perfect for Oracle beginners,’ that doesn’t preclude advanced and intermediate users from getting their fair share of toys! I’ve been working with Oracle since the 7.3.4 days, and I think it’s pretty safe to say that the WAY an ‘old timer’ uses a tool like SQL Developer is radically different than the ‘beginner.’ If you’ve been reluctant to use SQL Developer because it’s a GUI, give me a few minutes to try to convince you it’s worth a second (or third) look. 1. Help when you want it, and only when you want it One of the biggest gripes any user has with a piece of software is when said software can’t get out of it’s own way. When you’re typing in a word processor, sometimes you can do without the grammar and spelling checks, the offer to auto-complete your words, and all of the additional mark-up. This drives folks to programs like Notepad++ and vi. You can disable the code insight feature so you can type unmolested by SQL Developer’s attempt to auto-complete your object names. Now, if you happen to come across a long or hard to spell object name, you can still invoke the feature on demand using Ctrl+Spacebar Code Editor – Completion Insight – Enable Completion Auto-Popup (Keyword being Auto) 2. Automatic File Tracking SQL*Minus is nice. Vi is cool. Notepad++ has a lot of features I like. But not too many editors offer automatic logging of changes to your files without having to setup a source control system. I was doing some work on my login.sql. I’m not doing anything crazy, but seeing what I had done in previous iterations was helpful. Now imagine how nice it would be to have this available for your l,000+ line scripts! Track your scripts as they change, no setup required! 3. Extend the Functionality Know SQL and XML? Wish SQL Developer did JUST a little bit more? Build your own extensions. You can have custom context menus and object pages in just a few minutes. This is an example of lazy developers writing code that write code. 4. Get Your Money’s Worth You’ve licensed Enterprise Edition. You got your Diagnostic and Tuning packs. Now start using them! Not everyone has access to Enterprise Manager, especially developers. But that doesn’t mean they don’t need help with troubleshooting and optimizing poorly performing SQL statements. ASH, AWR, Real-Time SQL Monitoring and the SQL Tuning Advisor are built into the Reports and Worksheet. Yes you could make the package calls, but that’s a whole lot of typing, and I’d rather just get to the results. 5. Profile, Debug, & Unit Testing PLSQL An Interactive Development Environment (IDE) built by the same folks that own the programming language (Hello – Oracle PLSQL!) should be complete. It should ‘hug’ the developer and empower them to churn out programs that work, run fast, and are easy to maintain. Write it, test it, debug it, and tune it. When you’re running your programs and you just want to see the data that’s returned, that shouldn’t require any special settings or workaround to make it happen either. Magic! And a whole lot more… I could go on and talk about the support for things like DataPump, RMAN, and DBMS_SCHEDULER, but you’re experts and you’re plenty busy. If you think SQL Developer is falling short somewhere, I want you to let us know about it.

  • AdventureWorks2012 now available for all on SQL Azure

    - by jamiet
    Three days ago I tweeted this: Idea. MSFT could host read-only copies of all the [AdventureWorks] DBs up on #sqlazure for the SQL community to use. RT if agree #sqlfamily — Jamie Thomson (@jamiet) March 24, 2012 Evidently I wasn't the only one that thought this was a good idea because as you can see from the screenshot that tweet has, so far, been retweeted more than fifty times. Clearly there is a desire to see the AdventureWorks databases made available for the community to noodle around on so I am pleased to announce that as of today you can do just that - [AdventureWorks2012] now resides on SQL Azure and is available for anyone, absolutely anyone, to connect to and use* for their own means. *By use I mean "issue some SELECT statements". You don't have permission to issue INSERTs, UPDATEs, DELETEs or EXECUTEs I'm afraid - if you want to do that then you can get the bits and host it yourself. This database is free for you to use but SQL Azure is of course not free so before I give you the credentials please lend me your ears eyes for a short while longer. AdventureWorks on Azure is being provided for the SQL Server community to use and so I am hoping that that same community will rally around to support this effort by making a voluntary donation to support the upkeep which, going on current pricing, is going to be $119.88 per year. If you would like to contribute to keep AdventureWorks on Azure up and running for that full year please donate via PayPal to [email protected]: Any amount, no matter how small, will help. If those 50+ people that retweeted me beforehand all contributed $2 then that would just about be enough to keep this up for a year. If the community contributes more that we need then there are a number of additional things that could be done: Host additional databases (Northwind anyone??) Host in more datacentres (this first one is in Western Europe) Make a charitable donation That last one, a charitable donation, is something I would really like to do. The SQL Community have proved before that they can make a significant contribution to charitable orgnisations through purchasing the SQL Server MVP Deep Dives book and I harbour hopes that AdventureWorks on Azure can continue in that vein. So please, if you think AdventureWorks on Azure is something that is worth supporting please make a contribution. OK, with the prickly subject of begging for cash out of the way let me share the details that you need to connect to [AdventureWorks2012] on SQL Azure: Server mhknbn2kdz.database.windows.net  Database AdventureWorks2012 User sqlfamily Password sqlf@m1ly That user sqlfamily has all the permissions required to enable you to query away to your heart's content. Here is the code that I used to set it up: CREATE USER sqlfamily FOR LOGIN sqlfamily;CREATE ROLE sqlfamilyrole;EXEC sp_addrolemember 'sqlfamilyrole','sqlfamily';GRANT VIEW DEFINITION ON Database::AdventureWorks2012 TO sqlfamilyrole;GRANT VIEW DATABASE STATE ON Database::AdventureWorks2012 TO sqlfamilyrole;GRANT SHOWPLAN TO sqlfamilyrole;EXEC sp_addrolemember 'db_datareader','sqlfamilyrole'; You can connect to the database using SQL Server Management Studio (instructions to do that are provided at Walkthrough: Connecting to SQL Azure via the SSMS) or you can use the web interface at https://mhknbn2kdz.database.windows.net: Lastly, just for a bit of fun I created a table up there called [dbo].[SqlFamily] into which you can leave a small calling card. Simply execute the following SQL statement (changing the values of course): INSERT [dbo].[SqlFamily]([Name],[Message],[TwitterHandle],[BlogURI])VALUES ('Your name here','Some Message','your twitter handle (optional)','Blog URI (optional)'); [Id] is an IDENTITY field and there is a default constraint on [DT] hence there is no need to supply a value for those. Note that you only have INSERT permissions, not UPDATE or DELETE so make sure you get it right first time! Any offensive or distasteful remarks will of course be deleted :) Thank you for reading this far and have fun using AdventureWorks on Azure. I hope it proves to be useful for some of you. @jamiet AdventureWorks on Azure - Provided by the SQL Server community, for the SQL Server community!

  • Who Makes a Good Product Owner

    - by Robert May
    In general, the best product owners are those that care passionately about the customer of the product.  Note that I didn’t say about the product itself.  Actually, people that only care about the product, generally do not make good product owners.  Products only matter in relationship to their customers.  If a product doesn’t provide value to the customer, then the product has no value, no matter what a person might think of the product, and no matter what cool technologies exist inside of the product. A good product owner is also a good negotiator.  They recognize that many different priorities exist inside of a corporation, but that there can be only one list that developers work from.  A good product owner recognizes that its their job to help others around them prioritize (perhaps with a Product Council), but also understand that they alone have the final say about priorities and are willing to make the tough decisions required.  Deciding the priority between two perfectly valid stories is very difficult, especially when the stories are from two different departments! A good product owner is deeply interested in helping the team be successful.  They don’t seek to control the team, but instead seek to understand what the team can do and then work with the team to get the best product possible for the Customer.  A good product owner is never denigrating to team members, ever.  They recognize that such behavior would damage the trust that needs to be present between team members and product owners and will avoid it at all costs. In general, technical people (i.e. former or current developers) make poor product owners.  In their minds, they can’t separate implementation details from user functionality, so their stories end up sounding like implementation details.  For example, “The user enters their username on the password screen” is something that a technical product owner would write.  The proper wording for that story is “A user supplies the system with their credentials.”  Because technical people think different from the rest of the population, they are generally not a good fit. A good product owner is also a good writer.  Writing good stories demands good writing.  The art of persuasion, descriptiveness and just general good grammar are all required.  A good Product Owner must also be well spoken, since most of what will be conveyed will be conveyed with the spoken word, not just written word. A good product owner is a “People Person.”  They like talking to people and are very patient.  They don’t mind having questions repeated or fielding many questions, because they want to make sure that the ideas they’re conveying are properly understood so the customer gets the best product possible.  They are happy to answer any questions a team member may have and invite feedback and criticism of designs and stories, since they want a good product.  They really have little ego that gets in the way of building a great product. All of these qualities can be hard to find, but if you look close enough, you’ll find the right person in your organization.  Product owners can be found anywhere, not just in upper management.  Some of the best product owners are those that are very close to the customer.  In fact, check your customer support staff.  I’d bet that several great product owners are lurking there. Final note about what makes a good product owner.  You’re probably NOT going to find a good product owner in a manager, especially if they consider themselves a “Manager.”  Product owners don’t manage anything but the backlog, so be especially careful if the person you’re selecting for Product Owner is a manager. Up Next, “Messing with the Team.” Technorati Tags: Scrum,Product Owner

  • Knowledge Management Feedback

    - by Robert Schweighardt
    Did you know that you can provide feedback on Knowledge Management (KM) articles? It's nice to read a technical article that is well-written, the grammar and spelling are correct, the information is up to date, concise, to the point, easy to understand and it flows from one paragraph to another.  And though we always strive for a well-written article, it doesn't always come out that way. Knowledge Management articles are written by Oracle Support Engineers and we welcome your feedback.  Providing feedback helps to improve Oracle's Knowledge Base.  If you're reading a KM article and you have a comment, please let us know about it.  Maybe it's just to fix a spelling or grammatical error.  Maybe there's a broken link that needs to be fixed.  Maybe it's a suggestion to provide additional information.  Maybe the article contains incorrect information.  Maybe some information in the article is outdated.  Maybe something is not clear in the article.  Whatever it is, we want to hear about it.  We value your input! When you provide feedback it goes directly to the owner of the article.  The owner carefully reviews the comment and decides whether or not to implement it.  Most comments are implemented and we strive to implement them within a week!  For those comments that are not implemented, there is normally a good reason.  It may not be feasible to implement the suggestion or the suggestion may not be correct.  We don't take the decision lightly! So how do you provide feedback? Providing feedback on a KM article depends on whether you're a customer or an Oracle Employee. Customer 1. In the upper right hand corner of the article, click on the little +/- Rate this document icon: Note: The grayed out Comments (0) link will only show a number when there are open comments that are still being evaluated. 2. In the Article Rating window, complete as many of the following optional fields as you like and then click the Send Rating button: Rate the article as Excellent, Good or Poor Specify whether the article helped you or not Specify the ease of finding the article Provide whatever comments you have Employee The interface for Oracle Employees is a little bit different, there are more options. 1. The +/- Rate this document icon is also available to employees and is identical to what the customers have.  Please see Customer section above. 2. The Show document comments link shows all comments that have ever been submitted for the article 3. Employees have an additional way to submit a comment.  Click on the little + Add Comment icon: 4.

  • When is your interview?

    - by Rob Farley
    Sometimes it’s tough to evaluate someone – to figure out if you think they’d be worth hiring. These days, since starting LobsterPot Solutions, I have my share of interviews, on both sides of the desk. Sometimes I’m checking out potential staff members; sometimes I’m persuading someone else to get us on board for a project. Regardless of who is on which side of the desk, we’re both checking each other out. The world is not how it was some years ago. I’m pretty sure that every time I walk into a room for an interview, I’ve searched for them online, and they’ve searched for me. I suspect they usually have the easier time finding me, although there are obviously other Rob Farleys in the world. They may have even checked out some of my presentations from conferences, read my blog posts, maybe even heard me tell jokes or sing. I know some people need me to explain who I am, but for the most part, I think they’ve done plenty of research long before I’ve walked in the room. I remember when this was different (as it could be for you still). I remember a time when I dealt with recruitment agents, looking for work. I remember sitting in rooms having been giving a test designed to find out if I knew my stuff or not, and then being pulled into interviews with managers who had to find out if I could communicate effectively. I’d need to explain who I was, what kind of person I was, what my value-system involved, and so on. I’m sure you understand what I’m getting at. (Oh, and in case you hadn’t realised, it’s a T-SQL Tuesday post, this month about interviews.) At TechEd Australia some years ago (either 2009 or 2010 – I forget which), I remember hearing a comment made during the ‘locknote’, the closing session. The presenter described a conversation he’d heard between two girls, discussing a guy that one of them had just started dating. The other girl expressed horror at the fact that her friend had met this guy in person, rather than through an online dating agency. The presenter pointed out that people realise that there’s a certain level of safety provided through the checks that those sites do. I’m not sure I completely trust this, but I’m sure it’s true for people’s technical profiles. If I interview someone, I hope they have a profile. I hope I can look at what they already know. I hope I can get samples of their work, and see how they communicate. I hope I can get a feel for their sense of humour. I hope I already know exactly what kind of person they are – their value system, their beliefs, their passions. Even their grammar. I can work out if the person is a good risk or not from who they are online. If they don’t have an online presence, then I don’t have this information, and the risk is higher. So if you’re interviewing with me, your interview started long before the conversation. I hope it started before I’d ever heard of you. I know the interview in which I’m being assessed started before I even knew there was a product called SQL Server. It’s reflected in what I write. It’s in the way I present. I have spent my life becoming me – so let’s talk! @rob_farley

  • Jersey non blocking client

    - by Pavel Bucek
    Although Jersey already have support for making asynchronous requests, it is implemented by standard blocking way - every asynchronous request is handled by one thread and that thread is released only after request is completely processed. That is OK for lots of cases, but imagine how that will work when you need to do lots of parallel requests. Of course you can limit (and its really wise thing to do, you do want control your resources) number of threads used for asynchronous requests, but you'll get another maybe not pleasant consequence - obviously processing time will incerase. There are few projects which are trying to deal with that problem, commonly named as async http clients. I didn't want to "re-implement a wheel" and I decided I'll use AHC - Async Http Client made by Jeanfrancois Arcand. There is also interesting implementation from Apache - HttpAsyncClient, but it is still in "very early stages of development" and others haven't been in similar or better shape as AHC. How this works? Non-blocking clients allow users to make same asynchronous requests as we can do with standard approach but implementation is different - threads are better utilized, they don't spend most of time in idle state. Simply described - when you make a request (send it over the network), you are waiting for reply from other side. And there comes main advantage of non-blocking approach - it uses these threads for further work, like making other requests or processing responses etc.. Idle time is minimized and your resources (threads) will be far better used. Who should consider using this? Everyone who is making lots of asynchronous requests. I haven't done proper benchmark yet, but some simple dumb tests are showing huge improvement in cases where lots of concurrent asynchronous requests are made in short period. Last but not least - this module is still experimental, so if you don't like something or if you have ideas for improvements/any feedback, feel free to comment this blog post, send mail to [email protected] or contact me personally. All feedback is greatly appreciated! maven dependency (will be present in java.net maven 2 repo by the end of the day): link: http://download.java.net/maven/2/com/sun/jersey/experimental/jersey-non-blocking-client <dependency> <groupId>com.sun.jersey.experimental</groupId> <artifactId>jersey-non-blocking-client</artifactId> <version>1.9-SNAPSHOT</version> </dependency> code snippet: ClientConfig cc = new DefaultNonBlockingClientConfig(); cc.getProperties().put(NonBlockingClientConfig.PROPERTY_THREADPOOL_SIZE, 10); // default value, feel free to change Client c = NonBlockingClient.create(cc); AsyncWebResource awr = c.asyncResource("http://oracle.com"); Future<ClientResponse> responseFuture = awr.get(ClientResponse.class); // or awr.get(new TypeListener<ClientResponse>(ClientResponse.class) { @Override public void onComplete(Future<ClientResponse> f) throws InterruptedException { ... } }); javadoc (temporary location, won't be updated): http://anise.cz/~paja/jersey-non-blocking-client/

  • Getting Started with StreamInsight 2.1

    - by Roman Schindlauer
    If you're just beginning to get familiar with StreamInsight, you may be looking for a way to get started. What are the basics? How can I get my first StreamInsight application running so I can see how it works? Where is the 'front door' that will get me going? If that describes you, then this blog entry might be just what you need. If you're already a StreamInsight wiz, keep reading anyway - you may find some helpful links here that you weren't aware of. But here's what we'd like from you experienced readers in particular: if you know of other good resources that we missed, please feel free to add them in the comments below. We appreciate you sharing your expertise. The Book The basic documentation for StreamInsight is located in the MSDN Library (Microsoft StreamInsight 2.1). You'll notice that previous versions of StreamInsight are still there (1.2 and 2.0), but if you're just getting started you can stick to the 2.1 section. The documentation has been organized to function as reference material, which is fine after you're familiar with the technology. But if you're trying to learn the basics, you might want to take a different path instead of just starting at the top. The following is one map you can use. What Is StreamInsight? Here is a sequence of topics that should give you a good overview of what StreamInsight is and how it works: Overview answers the question, "what is it?"

    Originally posted on: http://geekswithblogs.net/Wchrabaszcz/archive/2014/08/02/azure---stairway-to-heaven.aspx  Before you’ll start reading please start to play this song.   OK boys and girls, time get familiar with clouds. Time to become a meteorologist. To be honest I don’t know how to start. Is cloud better or worse than on campus resources … hmm … it is just different. I think for successful adoption in cloud world IT Dinosaurs need to forget some “Private Cloud” virtualization bad habits, and learn new way of thinking. Take a look: - I don’t need any  tapes or  CDs  (Physical Kingdom of Windows XP and 2000) - I don’t need any locally stored MP3s (CD virtualization :-) - I can just stream music to your computer no matter whether my on-site infrastructure is powered on. Why not to do exactly the same with WebServer, SQL, or just rented for a while Windows server ? Let’s go, to the other side of the mirror. 1st  - register yourself for free one month trial, as happy MSDN subscriber you’ve got monthly budget to spent. In addition in default setting your limit protects you against loosing real money, if your toys will consume too much traffic and space. http://azure.microsoft.com/en-us/pricing/free-trial/ Once your account is ready forget WebPortal, we are PowerShell knights. http://go.microsoft.com/?linkid=9811175&clcid=0x409 #Authenticate yourself in Azure Add-AzureAccount #download once your settings file Get-AzurePublishSettingsFile #Import it to your PowerShell Module Import-AzurePublishSettingsFile "C:\Azure\[filename].publishsettings" #validation Get-AzureAccount Get-AzureSubscription #where are Azure datacenters Get-AzureLocation #You will need it Update-Help #storage account is related to physical location, there are two datacenters on each continent, try nearest to you # all your VMs will store VHD files on your storage account #your storage account must be unique globally, so I assume that words account or server are already used New-AzureStorageAccount -StorageAccountName "[YOUR_STORAGE_ACCOUNT]" -Label "AzureTwo" -Location "West Europe" Get-AzureStorageAccount #it looks like you are ready to deploy first VM, what templates we can use Get-AzureVMImage | Select ImageName #what a mess, let’s choose Server 2012 $ImageName = (Get-AzureVMImage)[74].ImageName $cloudSvcName = '[YOUR_STORAGE_ACCOUNT]' $AdminUsername = "[YOUR-ADMIN]" $adminPassword = '[YOUR_PA$$W0RD]' $MediaLocation = "West Europe" $vmnameDC = 'DC01' #burn baby burn !!! $vmDC01 = New-AzureVMConfig -Name $vmnameDC -InstanceSize "Small" -ImageName $ImageName   `     | Add-AzureProvisioningConfig -Windows -Password $adminPassword -AdminUsername $AdminUsername   `     | New-AzureVM -ServiceName $cloudSvcName #ice, ice baby … Get-AzureVM Get-AzureRemoteDesktopFile -ServiceName "[YOUR_STORAGE_ACCOUNT]" -Name "DC01" -LocalPath "c:\AZURE\DC01.rdp" As you can see it is not just a new-VM, you need to associate your VM with AzureVMConfig (it sets your template), AzureProvisioningConfig (it sets your customizations), and Storage account. In next releases you’ll need to put this machine in specific subnet, attach a HDD and many more. After second reading I found that I am using the same name for STORAGE and SERVICE account, please be aware of it if you need to split these values. Conclusions: - pipe rules ! - at the beginning it is hard to change your mind and agree with fact that it is easier to remove and recreate a VM than move it to different subnet - by default everything is firewalled, limited access to DNS, but NATed outside on custom ports. It is good to check these translations sometimes on the webportal. - if you remove your VMs your harddrives remains on storage and MS will charge you . Remove-AzureVM -DeleteVHD For me AZURE it is a lot of fun, once again I can be newbie and learn every page. For me Azure offers real freedom in deployment of VMs without arguing with NetAdmins, WinAdmins, DBAs, PMs and other Change Managers.

  • ORACLE is WEB 2.0

    - by anca.rosu
    You never know what to expect in life, where it can take you and what kind of fulfillment it can offer you. It’s just like an amazing lottery with millions of winning tickets. My name is Paula, I am an Online Marketing Specialist at Oracle University and this is my story. Having graduated from a technical profile college, it seemed almost normal to follow the same career path. But I said no. I wanted to try something else, so I took an Advertising Masters Program and I really became in love with this entire industry. Advertising and the new impact of the Internet through social networking is my current fascination. I knew I had to work to incorporate both my skills intro one dream job. I want to believe that I have come to work at Oracle as part of a great plan that life has for me. It’s not the most glamorous job in advertising or in the fashion industry, but it’s everything you need to start investing in your development and to build relationships. A normal day at work begins at 9.30 at our Oracle Office in Bucharest. After a short chit-chat, coffee and some conference calls, marketing gets to work! Some of the members of my team are working besides me but others are based all over Europe. This is extremely useful when coordinating the EMEA Marketing for Oracle University, because this way it’s easier to keep an eye on these various locations. Even though it’s a team play, you need to speak up and make your mark. I am the kind of person that never stands-by and waits to be given directions, I am curious and intuitive. This makes things easier. In Oracle you really need to find your own way and to discover how to organize your time and how to get involved with people. People to people, this is the focus. But everything is up to you and it strongly depends on the type of personality that you have. I try to get involved in various activities, participate in Oracle Days Events, interact and meet all kinds of people. For those who are newly graduates or interns, Oracle has lots of trainings and webcasts you can attend to help you develop your career shape and to understand better the way the business works. You can also be awarded for ideas and setting the trends so that makes it worth it. What I like most about my job is the fact that I can come with ideas and bring them to life. For example Oracle University has a special seminar program called “Celebrity Seminars” where top industry speakers teach 1-day or 2-day condensed seminars. We thought of creating something exclusive and a video was the best idea. So my colleague and I became reporters for a day and interviewed this well-known speaker regarding his seminar. I think this is a good way to market this business. Live footage is a very good marketing tool so we are planning to use the video to target our online audiences via Facebook, Twitter or LinkedIn. This can even go in the newsletters that marketing sends regarding the Celebrity Seminars. This is what I meant when I said Oracle is a free spirited organization and you can surely find your place here among us. The best way to describe my job is WEB 2.0. The modern online approach comes to life while we are trying to sell our business. We need to be out there and we are responsible of spreading the buzz regarding our training offerings and our official courseware materials. There are so many new ways to interact with the target audience nowadays and I am so eager to discover the best online techniques! 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 Technorati Tags: WEB 2.0,Online Marketing,Oracle University,Bucharest,events,graduates,interns,training,webcast,seminar,newsletters,business,Facebook,Twitter,LinkedIn

  • Access Music from Amie Street in Boxee

    - by Mysticgeek
    One of our favorite sites for discovering new music is Amie Street. Today we take a look at the Amie Street app for Boxee that allows you to access your favorite tunes from the Boxee interface. Amie Street is a cool site that allows you to discover a lot of cool music from independent artists. What makes Amie Street unique is that most of the music starts out free, then the price goes up incrementally as its popularity grows. The Amie Street App for Boxee let’s you access music and playlists you’ve created on the site, with more features are on the way. For this example we’re using the mouse and keyboard, but of course you can also get to each section using your remote if you have one. Or you can turn your iPod touch into a Boxee remote too. Amie Street in Boxee To access the Amie Street app, launch Boxee and click on Apps from the main menu. Under the Search Sidebar type in Amie Street and select it from the results field.   Then you can add it to the My Apps section…and double-click on the icon. Click on Start to begin using it. You’ll be be presented with a Welcome screen where you can sign into your account. If you don’t have an account yet, there is also an option to go to the Amie Street site and create one. Enter in your account credentials… Now you’ll be able to access your Library, Playlists, Search for new tunes, and check out your Recommended bands and artists. Hover the pointer over an album to get a bit more info about it such as the music genre. You’ll be able to play the songs from the playlists you created on the Amie Street site. You can browse through the history of the music you’ve played as well. Not all the features of this app seem to work as you’d expect them to, and some of the features are not yet available like the Browse feature.   Conclusion At the time of this writing we weren’t able to purchase music or get additional information about the artists. As development continues on Boxee and this app, you can expect more of a full user experience and the ability to purchase music. Even though some of the features are a bit buggy or not available, if you’re a Boxee user and a fan of Amie Street, this is cool app to add to your collection.

  • SQL SERVER – Puzzle #1 – Querying Pattern Ranges and Wild Cards

    - by Pinal Dave
    Note: Read at the end of the blog post how you can get five Joes 2 Pros Book #1 and a surprise gift. I have been blogging for almost 7 years and every other day I receive questions about Querying Pattern Ranges. The most common way to solve the problem is to use Wild Cards. However, not everyone knows how to use wild card properly. SQL Queries 2012 Joes 2 Pros Volume 1 – The SQL Queries 2012 Hands-On Tutorial for Beginners Book On Amazon | Book On Flipkart Learn SQL Server get all the five parts combo kit Kit on Amazon | Kit on Flipkart Many people know wildcards are great for finding patterns in character data. There are also some special sequences with wildcards that can give you even more power. This series from SQL Queries 2012 Joes 2 Pros® Volume 1 will show you some of these cool tricks. All supporting files are available with a free download from the www.Joes2Pros.com web site. This example is from the SQL 2012 series Volume 1 in the file SQLQueries2012Vol1Chapter2.2Setup.sql. If you need help setting up then look in the “Free Videos” section on Joes2Pros under “Getting Started” called “How to install your labs” Querying Pattern Ranges The % wildcard character represents any number of characters of any length. Let’s find all first names that end in the letter ‘A’. By using the percentage ‘%’ sign with the letter ‘A’, we achieve this goal using the code sample below: SELECT * FROM Employee WHERE FirstName LIKE '%A' To find all FirstName values beginning with the letters ‘A’ or ‘B’ we can use two predicates in our WHERE clause, by separating them with the OR statement. Finding names beginning with an ‘A’ or ‘B’ is easy and this works fine until we want a larger range of letters as in the example below for ‘A’ thru ‘K’: SELECT * FROM Employee WHERE FirstName LIKE 'A%' OR FirstName LIKE 'B%' OR FirstName LIKE 'C%' OR FirstName LIKE 'D%' OR FirstName LIKE 'E%' OR FirstName LIKE 'F%' OR FirstName LIKE 'G%' OR FirstName LIKE 'H%' OR FirstName LIKE 'I%' OR FirstName LIKE 'J%' OR FirstName LIKE 'K%' The previous query does find FirstName values beginning with the letters ‘A’ thru ‘K’. However, when a query requires a large range of letters, the LIKE operator has an even better option. Since the first letter of the FirstName field can be ‘A’, ‘B’, ‘C’, ‘D’, ‘E’, ‘F’, ‘G’, ‘H’, ‘I’, ‘J’ or ‘K’, simply list all these choices inside a set of square brackets followed by the ‘%’ wildcard, as in the example below: SELECT * FROM Employee WHERE FirstName LIKE '[ABCDEFGHIJK]%' A more elegant example of this technique recognizes that all these letters are in a continuous range, so we really only need to list the first and last letter of the range inside the square brackets, followed by the ‘%’ wildcard allowing for any number of characters after the first letter in the range. Note: A predicate that uses a range will not work with the ‘=’ operator (equals sign). It will neither raise an error, nor produce a result set. --Bad query (will not error or return any records) SELECT * FROM Employee WHERE FirstName = '[A-K]%' Question: You want to find all first names that start with the letters A-M in your Customer table and end with the letter Z. Which SQL code would you use? a. SELECT * FROM Customer WHERE FirstName LIKE 'm%z' b. SELECT * FROM Customer WHERE FirstName LIKE 'a-m%z' c. SELECT * FROM Customer WHERE FirstName LIKE 'a-m%z' d. SELECT * FROM Customer WHERE FirstName LIKE '[a-m]%z' e. SELECT * FROM Customer WHERE FirstName LIKE '[a-m]z%' f. SELECT * FROM Customer WHERE FirstName LIKE '[a-m]%z' g. SELECT * FROM Customer WHERE FirstName LIKE '[a-m]z%' Contest Leave a valid answer before June 18, 2013 in the comment section. 5 winners will be selected from all the valid answers and will receive Joes 2 Pros Book #1. 1 Lucky person will get a surprise gift from Joes 2 Pros. The contest is open for all the countries where Amazon ships the book (USA, UK, Canada, India and many others).

  • App Stores&ndash;In All Things, Its Quality Over Quantity

    - by D'Arcy Lussier
    Everybody has an opinion about Windows 8. People love it, people hate it, people are meh about it, people are apparently buying it from Microsoft stores in NYC as if it was water before a natural disaster…if there’s one thing that Microsoft product launches do well, its the ability to bring out strong emotional responses. Over at eweek.com, Don Reisinger wrote about 5 good and bad things about Windows 8. Yes, another opinion piece on WIndows 8. I figured since this one had good and bad it might be worthwhile to read. I then came across #10 on his list, and figured “What the hell…might as well post a bit of a rant on Windows 8 myself!” Here’s #10: 10. Bad: Too few apps Unfortunately, Microsoft wasn’t able to get too many developers to start producing applications for its Windows 8 Store. Microsoft hasn’t yet released official numbers, but some have said that the marketplace has less than 8,000 programs. Considering Apple’s App Store has 100 times that, it’s about time Microsoft starts leaning on developers to get more programs into its store. Believe me, Microsoft *has* been leaning on developers to get apps into the store. I’ve been asked at least 5 or 6 times from 5 or 6 different friends at Microsoft about whether I was going to write a Windows 8 app. I think Microsoft felt they had to try and address the number of apps available in their marketplace, since some people (like Don) would draw comparisons to the number of apps in the Apple marketplace. I feel for Microsoft in this, since the number of apps in a marketplace are an empty stat. Quality of Quantity I have an iPad that my family (wife, 10yo daughter, 3yo daughter) use. We all have our own apps installed on it. In addition, my wife has an iPhone 4S that she also installs apps on. As someone who gets asked by his kids often whether they can buy/download an app, the vast majority of the vast catalogue of iOS marketplace apps are crap! Do you realize how many “free” games are out there, only to really be not-free because you have to purchase in-game content to make the game actually playable? And how about searching – with such a vast array of apps and such high numbers of craptastic ones, trying to find something is incredibly difficult and can be frustrating. I would rather see that Microsoft has 8000 high quality apps in their store at launch, instead of 800000 that were mostly junk. Too Few Apps?! And seriously, 8000 is not a small number. How many iOS apps have I actually bought between the iPad and iPhone? I’ll be generous and say 30…heck, let’s round it up to 40. It’s not like I have 10,000 apps installed on my iPad, nor will that ever happen! So if people have, at the *launch* of a new platform ecosystem, EIGHT THOUSAND apps to choose from, I don’t see that as a fail at all! It should be noted that most of the most common apps (Netflix, Skype, etc.) are available for Windows 8 at launch – I guess I’ll have to wait a few weeks for My Pony Ranch and all its clones to start showing up; pity. Let’s Check Back in a Year So look, let’s check back in a year’s time and see what the app store looks like. My hope is that Microsoft doesn’t continue to push quantity over quality. Even knowing the optics that # of apps in the store carries and the pressure to catch Apple and Android marketplaces, I hope Microsoft avoids the scenario where there’s a good percentage of apps in the Windows Store that are utter rubbish and finding the gems will be cumbersome. But if that happens, we can thank guys like Dan who raised the false issue of app count at the launch for it.

  • Live Event: OTN Architect Day: Cloud Computing - Two weeks and counting

    - by Bob Rhubart
    In just two weeks architects and others will gather at the Oracle Conference Center in Redwood Shores, CA for the first Oracle Technology Network Architect Day event of 2013. This event focuses on Cloud Computing, and features sessions specifically focused on real-world examples of the implementation of cloud computing. When: Tuesday July 9, 2013              8:30am - 12:30pm Where: Oracle Conference Center              350 Oracle Pkwy              Redwood City, CA 94065 Register now. It's free! Here's the agenda: 8:30am - 9:00am Registration and Continental Breakfast 9:00am - 9:45am Keynote 21st Century IT | Dr. James Baty VP, Global Enterprise Architecture Program, Oracle Imagine a time long, long ago. A time when servers were certified and dedicated to specific applications, when anything posted on an enterprise web site was from restricted, approved channels, and when we tried to limit the growth of 'dirty' data and storage. Today, applications are services running in the muti-tenant hybrid cloud. Companies beg their customers to tweet them, friend them, and publicly rate their products. And constantly analyzing a deluge of Internet, social and sensor data is the key to creating the next super-successful product, or capturing an evil terrorist. The old IT architecture was planned, dedicated, stable, controlled, with separate and well-defined roles. The new architecture is shared, dynamic, continuous, XaaS, DevOps. This keynote session describes the challenges and opportunities that the new business / IT paradigms present to the IT architecture and architects. 9:45am - 10:30am Technical Session Oracle Cloud: A Case Study in Building a Cloud | Anbu Krishnaswami Enterprise Architect, Oracle Building a Cloud can be challenging thanks to the complex requirements unique to Cloud computing and the massive scale typically associated with Cloud. Cloud providers can take an Infrastructure as a Service (IaaS) approach and build a cloud on virtualized commodity hardware, or they can take the Platform as a Service (PaaS) path, a service-oriented approach based on pre-configured, integrated, engineered systems. This presentation uses the Oracle Cloud itself as a case study in the use of engineered systems, demonstrating how the technical design of engineered systems is leveraged for building PaaS and SaaS Cloud services and a Cloud management infrastructure. The presentation will also explore the principles, patterns, best practices, and architecture views provided in Oracle's Cloud reference architecture. 10:30 am -10:45 am Break 10:45am-11:30am Technical Session Database as a Service | Michael Timpanaro-Perrotta Director, Product Management, Oracle Database Cloud New applications are now commonly built in a Cloud model, where the database is consumed as a service, and many established business processes are beginning to migrate to database as a service (DBaaS). This adoption of DBaaS is made possible by the availability of new capabilities in the database that enable resource pooling, dynamic resource management, model-based provisioning, metered use, and effective quality-of-service controls. This session will examine the catalog of database services at a large commercial bank to understand how these capabilities are enabling DBaaS for a wide range of needs within the enterprise. 11:30 am - 12:00 pm Panel Q&A Dr. James Baty, Anbu Krishnaswami, and Michael Timpanaro-Perrotta respond to audience questions. Registration is free, but seating is limited, so register now.

  • 65536% Autogrowth!

    - by Tara Kizer
    Twice a year, we move our production systems to our disaster recovery site.  Last Saturday night was one of those days.  There are about 50 SQL Server databases to be moved to the DR site, which is done via database mirroring.  It takes only a few seconds to failover, but some databases have a bit more involved work such as setting up replication.  Everything went relatively smooth, but we encountered a weird bug on our most mission critical system.  After everything was successfully failed over to the DR site, it was noticed that mirroring was in a suspended state on one of the databases.  We thought we had run into a SQL Server 2005 bug that we had been encountering and were working with Microsoft on a fix.  Microsoft did fix it in both SQL Server 2005 service pack 3 cumulative update package 13 and service pack 4 cumulative update package 2, however SP3 CU13 and SP4 both recently failed on this system so we were not patched yet with the bug fix.  As the suspended state was causing us issues with replication, we dropped mirroring.  We then noticed we had 10MB of free disk space on the mount point where the principal’s data files are stored.  I knew something went amiss as this system should have at least 150GB free on that mount point.  I immediately checked the main database’s data file and was shocked to see an autgrowth size of 65536%.  The data file autogrew right before mirroring went into the suspended state. 65536%! I didn’t have a lot of time to research if this autgrowth problem was a known SQL Server bug, so I deferred that research to today.  A quick Google search yielded no results but emphasis on “quick”.  I checked our performance system, which was recently restored with a copy of the affected production database, and found the autogrowth setting to be 512MB.  So this autogrowth bug was encountered sometime in the last two weeks.  On February 26th, we had attempted to install SQL 2005 SP4 on production, however it had failed (PSS case open with Microsoft).  I suspected that the SP4 failure was somehow related to this autgrowth bug although that turned out not to be the case. I then tweeted (@TaraKizer) about this problem to see if the SQL Server community (#sqlhelp) had any insights.  It seems several people have either heard of this bug or encountered it.  Aaron Bertrand (blog|twitter) referred me to this Connect item. Our affected database originated on SQL Server 2000 and was upgraded to SQL Server 2005 in 2007.  Back on SQL Server 2000, we were using the default file growth setting which was a percentage.  Sometime after the 2005 upgrade is when we changed it to 512MB.  Our situation seemed to fit the bug Aaron referred to me, so now the question was whether Microsoft had fixed it yet. I received a reply to my tweet from Amit Banerjee (twitter) that it had been fixed in SP3 CU1 (KB958004).  My affected system is SP3 CU8, so I was initially confused why we had encountered the bug.  Because I don’t read things fully, I had missed that there are additional steps you have to follow after applying the bug fix.  Amit set me straight.  Although you can read this information in the KB article, I will also copy it here in case you are as lazy as me and miss the most important section of it (although if you are as lazy as me, you won’t have read this far down my blog post): This hotfix will prevent only future occurrences of this problem. For example, if you restore a database from SQL Server 2000 to a SQL Server 2005 instance that contains this hotfix, this problem will not occur. However, if you already have a database that is affected by this problem, you must follow these steps to resolve this problem manually: Apply this hotfix. Set the file growth settings for the affected files to percentage settings, and then set the settings back to megabyte settings. Take the database offline, and then bring it back online. Verify that the values of the is_percent_growth column are correct in the sys.database_files system table and in the sys.master_files system table.

  • Updated SOA Documents now available in ITSO Reference Library

    - by Bob Rhubart
    Nine documents within the IT Strategies from Oracle (ITSO) reference library have recently been updated. (Access to the ITSO collection is free to registered Oracle.com members -- and that membership is free.) All nine documents fall within the Service Oriented Architecture section of the ITSO collection, and cover the following topics: SOA Practitioner Guides Creating an SOA Roadmap (PDF, 54 pages, published: February 2012) The secret to successful SOA is to build a roadmap that can be successfully executed. SOA offers an opportunity to adopt an iterative technique to deliver solutions incrementally. This document offers a structured, iterative methodology to help you stay focused on business results, mitigate technology and organizational risk, and deliver successful SOA projects. A Framework for SOA Governance (PDF, 58 pages, published: February 2012) Successful SOA requires a strong governance strategy that designs-in measurement, management, and enforcement procedures. Enterprise SOA adoption introduces new assets, processes, technologies, standards, roles, etc. which require application of appropriate governance policies and procedures. This document offers a framework for defining and building a proper SOA governance model. Determining ROI of SOA through Reuse (PDF, 28 pages, published: February 2012) SOA offers the opportunity to save millions of dollars annually through reuse. Sharing common services intuitively reduces workload, increases developer productivity, and decreases maintenance costs. This document provides an approach for estimating the reuse value of the various software assets contained in a typical portfolio. Identifying and Discovering Services (PDF, 64 pages, published: March 2012) What services should we build? How can we promote the reuse of existing services? A sound approach to answer these questions is a primary measure for the success of a SOA initiative. This document describes a pragmatic approach for collecting the necessary information for identifying proper services and facilitating service reuse. Software Engineering in an SOA Environment (PDF, 66 pages, published: March 2012) Traditional software delivery methods are too narrowly focused and need to be adjusted to enable SOA. This document describes an engineering approach for delivering projects within an SOA environment. It identifies the unique software engineering challenges faced by enterprises adopting SOA and provides a framework to remove the hurdles and improve the efficiency of the SOA initiative. SOA Reference Architectures SOA Foundation (PDF, 70 pages, published: February 2012) This document describes they key tenets for SOA design, development, and execution environments. Topics include: service definition, service layering, service types, the service model, composite applications, invocation patterns, and standards. SOA Infrastructure (PDF, 86 pages, published: February 2012) Properly architected, SOA provides a robust and manageable infrastructure that enables faster solution delivery. This document describes the role of infrastructure and its capabilities. Topics include: logical architecture, deployment views, and Oracle product mapping. SOA White Papers and Data Sheets Oracle's Approach to SOA (white paper) (PDF, 14 pages, published: February 2012) Oracle has developed a pragmatic, holistic approach, based on years of experience with numerous companies to help customers successfully adopt SOA and realize measureable business benefits. This executive datasheet and whitepaper describe Oracle's proven approach to SOA. Oracle's Approach to SOA (data sheet) (PDF, 3 pages, published: March 2012) SOA adoption is complex and success is far from assured. This is why Oracle has developed a pragmatic, holistic approach, based on years of experience with numerous companies, to help customers successfully adopt SOA and realize measurable business benefits. This data sheet provides an executive overview of Oracle's proven approach to SOA.

  • Launch 7:Windows Phone 7 Style Live Tiles On Android Mobiles

    - by Gopinath
    Android is a great mobile OS but one thought that lingers in the mind of few Android owners is: Am I using a cheap iPhone? This is valid thought for many low end Android users as their phones runs sluggish and the user interface of Android looks like an imitation of iOS. When it comes to Windows Phone 7 users, even though their operating system features are not as great as iPhone/Android but it has its unique user interface; Windows Phone 7 user interface is a very intuitive and fresh, it’s constantly updating Live Tiles show all the required information on the home screen. Android has best mobile operating system features except UI and Windows Phone 7 has excellent user interface. How about porting Windows Phone 7 Tiles interface on an Android? That should be great. Launch 7 app brings the best of Windows Phone 7 look and feel to Android OS. Once the Launcher 7 app is installed and activated, it brings Live Tiles or constantly updating controls that show information on Android home screen. Apart from simple and smooth tiles, there are handful of customization options provided. Users can change colour of the tiles, add new tiles, enable/disable transitions. The reviews on Android Market are on the positive side with 4.4 stars by 10,000 + reviewers. Here are few user reviews 1. Does what it says. only issue for me is that the app drawer doesn’t rotate. And I would like the UI to rotate when my KB is opened. HTC desire z – Jonathan 2. Works great on atrix.Kudos to developers. Awesome. Though needs: Better notification bar More stock images of tiles Better fitting of widgets on tiles – Manny 3. Looks really good like it much more than I thought I would runs real smooth running royal ginger 2.1 – Jay 4. Omg amazing i am definetly keeping it as my default best of android and windows – Devon 5. Man! An update every week! Very very responsive developer! – Andrew You can read more reviews on Android Market here.  There is no doubt that this application is receiving rave reviews. After scanning a while through the reviews, few complaints throw light on the negative side: Battery drains a bit faster & Low end mobile run a bit sluggish. The application is available in two versions – an ad supported free version and $1.41 ad free version.

  • 2013 Predictions for Retail

    - by David Dorf
    Its that time of year to roll out the predictions for next year.  I can't say I've really nailed it in the past, but feel free to look back at my 2012, 2011, and 2010 predictions.  I'm not expecting anything earth-shattering this year; just continued maturation of several technologies that are finally taking hold. 1. Next day delivery -- Amazon finally decided it wasn't worth fighting state taxes and instead decided to place distribution centers everywhere so they can potentially offer next-day deliveries.  Not to be outdone, Walmart is looking to leverage its huge physical presence to offer the same.  Clubs like ShopRunner are pushing delivery barriers as well, so the norm is shifting to free shipping in a few days or relatively cheap shipping overnight.  Retailers need be thinking about how to ship from physical stores. 2. Bring your own device -- Earlier this year Intuit bought AisleBuyer, a mobile self-checkout start-up, at least somewhat validating the BYOD approach.  Grocery stores, especially in Europe, have been supporting in-aisle self-scanning for a while and I'm betting it will find a home in certain verticals in the US too.  There's also the BYOD concept for employees.  Some retailers are considering issuing mobile devices at hiring along side the shirt and name-tag.  Employees become responsible for the hardware until they leave. 3. TV shopping -- Will Apple finally release a TV product in 2013?  Who knows?  But the industry isn't standing still. Companies like QVC and HSN are already successfully combining the TV and online experiences for shopping.  Comcast is partnering with Tivo to allow viewers to interact with ads with Paypal handing payment.  This will be a slow maturation, but expect TVs to get smarter and eventually become a new selling channel (pun intended) for retailers. 4. Privacy backlash -- It only takes one big incident to stir the public, and I'm betting we have one in 2013.  Facebook, Google, or Apple will test the boundaries of what the public is willing to accept.  It could involve a retailer using geo-location technology, or possibly video analytics.  And as is always the case, the offender will apologize, temporarily remove the technology, and wait 2-3 years for it to be generally accepted.  Privacy is a moving target. 5. More NFC -- I've come to the conclusion that adoption of any banking technology is going to be slow.  It was slow for credit cards, ATMs, and online billpay so why should it be any different for NFC?  Maybe, just maybe the iPhone 5S will have an NFC chip, but we're not going to see mainstream uptake for years.  Next year we'll continue to see incremental improvements from Isis, Google, and Paypal and a plethora of new startups, but don't toss your magstripe cards just yet. 6. In-store location -- The technologies for tracking people inside stores is really improving.  Retailers can track people using video cameras, infrared, and by the WiFi radios in mobile phones.  We're getting closer to the point where accuracy could be a shelf-facing, which will help retailers understand how people shop, where they spend time, and what displays attract them.  Expect CPG companies to get involved and partner with retailers, since the data benefits both parties.  Consumers will benefit by being directed right to the products they seek.  (In 2013 ARTS is forming a workteam to develop new standards in this area.) 7. M&A -- Looking back at 2012 there were some really big deals involving IBM, Oracle, JDA, and NCR and I expect that trend will likely continue as vendors add assets to bolster their portfolios.  Many retailers are due for an IT transformation to support anywhere, anytime shoppers, and one-stop-vendors can minimize complexity and costs.
