• Last GUID used up - new ScottGuID unique ID to replace it

  - by Eilon

  You might have heard in recent news that the last ever GUID was used up. The GUID {FFFFFFFF-FFFF-FFFF-FFFF-FFFFFFFFFFFF} was just consumed by a soon to be released project at Microsoft. Immediately after the GUID's creation the word spread around the Microsoft campuses around the globe. Microsoft's approximately 100,000 worldwide employees then started blogging, tweeting, and facebooking about the dubious "achievement." The following screenshot shows GUIDGEN (the Windows tool for creating GUIDs) with the last ever GUID. All GUIDs created by projects at Microsoft must be registered in a central repository for record keeping. This allows quick-fix engineers, security engineers, anti-malware developers, and testers to do a quick look up of an unknown GUID and find out if it belongs to Microsoft. The following screenshot shows the Microsoft GUID Tracker internal application and the last few GUIDs being used up by various Microsoft projects. What is perhaps more interesting than the news about the GUID is the project that used that last GUID. The recent announcements regarding the development experience for the Windows Phone 7 Series (WP7S) all involve free editions of Visual Studio 2010. One of the lesser known developer tools is based on a resurrected project that many of you are probably familiar with, but have never used. The tool is in fact Microsoft Bob 7 Series (MB7S). MB7S is an agent-based approach for mobile phone app development. The UI incorporates both natural language interfaces and motion gesture behaviors, similar to the Windows Phone 7 Series “Metro” interface. If it works, it will help to expand the breadth of mobile app developers. After the GUID: The ScottGuID It came as no big surprise that eventually the last GUID would be used up. Knowing this, a group of engineers at Microsoft has designed, implemented, and tested a replacement to the GUID: The ScottGuID. There are several core principles of the ScottGuID: 1. The concepts used in ScottGuIDs must be easily understood by a developer who is already familiar with GUIDs 2. There must exist a compatibility layer between ScottGuIDs and GUIDs 3. A ScottGuID must be usable in a practical manner in non-computing environments 4. There must exist ScottGuID APIs for all common platforms: Win32/Win64/WinCE, .NET (incl. Silverlight), Linux, FreeBSD, MacOS (incl. iPhone OS), Symbian, RIM BlackBerry, Google Android, etc. 5. ScottGuIDs must never run out ScottGuID use cases One of the more subtle principles of the ScottGuID is principle #3. While technically a GUID could be used in any environment, it was not practical to do so in terms of data entry and error detection. In order to have the ScottGuID be a true universal ID it must be usable in non-computing environments. Prior to the announcement of the ScottGuID there have been a number of until-now confidential projects. One of the tools that will soon become public is ScottGuIDGen, which is in essence an updated version of GUIDGEN that can create ScottGuIDs. The following screenshot shows a sample ScottGuID. To demonstrate the various applications of the ScottGuID there were test deployments around the globe. The following examples are a small showcase of the applications that have already been prototyped. Log in to Hotmail: Pay for gas: Sign in to Twitter: Dispense cat food: Conclusion I hope that this brief introduction to the ScottGuID shows how technology can continue to move forward, even when it appears there is a point that cannot be passed. With a small number of principles, a team of smart engineers, and a passion for "getting it right" the ScottGuID should last well past our lifetimes. In the coming months expect further announcements regarding additional developer tools, samples, whitepapers, podcasts, and videos. Please leave a comment on this post if you have any questions about the ScottGuID or what you would like to see us do with it. With ScottGuID, the possibilities are nearly endless and we want to stretch their reach as far as possible.

• Tuxedo 11gR1 Client Server Affinity

  - by todd.little

  One of the major new features in Oracle Tuxedo 11gR1 is the ability to define an affinity between clients and servers. In previous releases of Tuxedo, the only way to ensure that multiple requests from a client went to the same server was to establish a conversation with tpconnect() and then use tpsend() and tprecv(). Although this works it has some drawbacks. First for single-threaded servers, the server is tied up for the entire duration of the conversation and cannot service other clients, an obvious scalability issue. I believe the more significant drawback is that the application programmer has to switch from the simple request/response model provided by tpcall() to the half duplex tpsend() and tprecv() calls used with conversations. Switching between the two typically requires a fair amount of redesign and recoding. The Client Server Affinity feature in Tuxedo 11gR1 allows by way of configuration an application to define affinities that can exist between clients and servers. This is done in the *SERVICES section of the UBBCONFIG file. Using new parameters for services defined in the *SERVICES section, customers can determine when an affinity session is created or deleted, the scope of the affinity, and whether requests can be routed outside the affinity scope. The AFFINITYSCOPE parameter can be MACHINE, GROUP, or SERVER, meaning that while the affinity session is in place, all requests from the client will be routed to the same MACHINE, GROUP, or SERVER. The creation and deletion of affinity is defined by the SESSIONROLE parameter and a service can be defined as either BEGIN, END, or NONE, where BEGIN starts an affinity session, END deletes the affinity session, and NONE does not impact the affinity session. Finally customers can define how strictly they want the affinity scope adhered to using the AFFINITYSTRICT parameter. If set to MANDATORY, all requests made during an affinity session will be routed to a server in the affinity scope. Thus if the affinity scope is SERVER, all subsequent tpcall() requests will be sent to the same server the affinity scope was established with. If the server doesn't offer that service, even though other servers do offer the service, the call will fail with TPNOENT. Setting AFFINITYSTRICT to PRECEDENT tells Tuxedo to try and route the request to a server in the affinity scope, but if that's not possible, then Tuxedo can try to route the request to servers out of scope. All of this begs the question, why? Why have this feature? There many uses for this capability, but the most common is when there is state that is maintained in a server, group of servers, or in a machine and subsequent requests from a client must be routed to where that state is maintained. This might be something as simple as a database cursor maintained by a server on behalf of a client. Alternatively it might be that the server has a connection to an external system and subsequent requests need to go back to the server that has that connection. A more sophisticated case is where a group of servers maintains some sort of cache in shared memory and subsequent requests need to be routed to where the cache is maintained. Although this last case might be able to be handled by data dependent routing, using client server affinity allows the cache to be partitioned dynamically instead of statically.

• Managing User & Role Security with Oracle SQL Developer

  - by thatjeffsmith

  With the advent of SQL Developer v3.0, users have had access to some powerful database administration features. Version 3.1 introduced more powerful features such as an interface to Data Pump and RMAN. Today I want to talk about some very simple but frequently ran tasks that SQL Developer can assist with, like: identifying privs granted to users managing role privs assigning new roles and privs to users & roles Before getting started, you’ll need a connection to the database with the proper privileges. The common ROLE used to accomplish this is the ‘DBA‘ role. Curious as to what the DBA role is actually comprised of? Let’s find out! Open the DBA Console First make sure you’re connected to the database you want to manage security on with a privileged administrator account. Then open the View menu and select ‘DBA.’ Accessing the DBA panel ‘Create’ a Connection Click on the green ‘+’ button in the DBA panel. It will ask you to choose a previously defined SQL Developer connection. Defining a DBA connection in Oracle SQL Developer Once connected you will see a tree list of DBA features you can start interacting with. Expand the ‘Security’ Tree Node As you click on an object in the DBA panel, the ‘viewer’ will open on the right-hand-side, just like you are accustomed to seeing when clicking on a table or stored procedure. Accessing the DBA role If I’m a newly hired Oracle DBA, the first thing I might want to do is become very familiar with the DBA role. People will be asking you to grant them this role or a subset of its privileges. Once you see what the role can do, you will become VERY protective of it. My favorite 3-letter 4-letter word is ‘ANY’ and the DBA role is littered with privileges like this: ANY TABLE privs granted to DBA role So if this doesn’t freak you out, then maybe you should re-consider your career path. Or in other words, don’t be granting this role to ANYONE you don’t completely trust to take care of your database. If I’m just assigned a new database to manage, the first thing I might want to look at is just WHO has been assigned the DBA role. SQL Developer makes this easy to ascertain, just click on the ‘User Grantees’ panel. Who has the keys to your car? Making Changes to Roles and Users If you mouse-right-click on a user in the Tree, you can do individual tasks like grant a sys priv or expire an account. But, you can also use the ‘Edit User’ dialog to do a lot of work in one pass. As you click through options in these dialogs, it will build the ‘ALTER USER’ script in the SQL panel, which can then be executed or copied to the worksheet or to your .SQL file to be ran at your discretion. A Few Clicks vs a Lot of Typing These dialogs won’t make you a DBA, but if you’re pressed for time and you’re already in SQL Developer, they can sure help you make up for lost time in just a few clicks!

• You Are Hiring But Do Candidate&rsquo;s Want to Work For You

  - by david.talamelli

  So here you are – it has happened, you are now interviewing for that position that you have either applied for or maybe were called about. Whether you are an “active” candidate looking for a job or a “passive” candidate who was contacted about the opportunity, it doesn’t matter now. Regardless of the circumstances of how you got to the interview stage, how you and your new potential manager connect with each other at interview will play a part in whether you are successful in landing that job. The best manager/employee relationships I think tend to be the ones where both the manager and employee have a common goal that they are both working towards and they work together in unison to achieve these goals. Candidates – when you are interviewing for a role, remember that an interview is a two way process. An interview shouldn’t be just a case of a company interviewing you to see if you are a good fit for a certain role. Don’t forget in an interview process it is equally important that you take the opportunity to similarly interview the company to see if that role/company are the right place for you to move to as the next step in your career. I think an interview should not only be a chance for a Hiring Manager to get to better know a candidate and asses his capability and cultural fit for a team/company but it should also be a chance for the candidate to similarly assess a company or manager about whether they are someone that they want to work with. Managers – I know Recruiters have been talking about the “war for talent” since before many of you were managers, but there is no denying it – it exists. You are not only competing with other companies for talented individuals but you are also competing with the existing companies that those talented individuals are working at. Companies are not going to let the people they have identified as superstars resign without a fight (this is the classic Counter Offer scenario which may be another blog post in itself). So how do we get these great people – their current employer will do all they can to keep them, everyone else wants them – does this mean all hope is lost? No, absolutely not. The same reasons that have always existed on why candidates are interested in other opportunities is still there: it could be that someone is looking for career advancement, or they want the chance to work with new technology or maybe you have an opportunity that is exactly what that person is looking to do. As a Hiring Manager don’t just conduct your interviews in question/answer mode. You should talk to that individual to work out what it is they are looking for and you can then relate how your role addresses that. It is potentially going to be the two of you working together so you two are the ones who have to be most comfortable with each other. Don’t oversell the role – set realistic expectations of what that candidate can expect working in your team – give them the good, the bad and the ugly so they can make an informed decision. Manager’s think back to when you last were looking for a job and put yourself in the candidate’s shoes. When you were looking for a job, what was it that you wanted to know about Oracle, or what was it that you wanted more information about. There are some great Business Leaders that work here at Oracle – if you are one of them it is likely that you already are doing all these things anyway. The good news for you is that you are also likely raising yourself head and shoulders above what many interviewers do – that in itself gives you a competitive advantage in this ‘war for talent’ but as a great Business Leader you already know that

• SQL SERVER – Puzzle – Statistics are not Updated but are Created Once

  - by pinaldave

  After having excellent response to my quiz – Why SELECT * throws an error but SELECT COUNT(*) does not?I have decided to ask another puzzling question to all of you. I am running this test on SQL Server 2008 R2. Here is the quick scenario about my setup. Create Table Insert 1000 Records Check the Statistics Now insert 10 times more 10,000 indexes Check the Statistics – it will be NOT updated Note: Auto Update Statistics and Auto Create Statistics for database is TRUE Expected Result – Statistics should be updated – SQL SERVER – When are Statistics Updated – What triggers Statistics to Update Now the question is why the statistics are not updated? The common answer is – we can update the statistics ourselves using UPDATE STATISTICS TableName WITH FULLSCAN, ALL However, the solution I am looking is where statistics should be updated automatically based on algorithm mentioned here.

• Beginner Geek: Scan a Document or Picture in Windows 7

  - by Mysticgeek

  There may come a time when you want to digitize your priceless old pictures, or need to scan a receipts and documents for your company. Today we look at how to scan a picture or document in Windows 7. Scanning Your Document In this example we’re using an HP PSC 1500 All-In-One printer connected to a Windows 7 Home Premium 32-bit system. Different scanners will vary, however the process is essentially the same. The scanning process has changed a bit since the XP days. To scan a document in Windows 7, place the document or picture in the scanner, click on Start, and go to Devices and Printers.   When the Devices and Printers window opens, find your scanning device and double-click on it to get the manufacturers Printer Actions menu. For our HP PSC 1500 we have a few different options like printing, device setup, and scanner actions. Here we’ll click on the Scan a document or photo hyperlink. The New Scan window opens and from here you can adjust the quality of the scanned image and choose the output file type. Then click the Preview button to get an idea of what the image will look like.   If you’re not happy with the preview, then you can go back and make any adjustments to the quality of the document or photo. Once everything looks good, click on the Scan button. The scanning process will start. The amount of time it takes will depend on your scanner type, and the quality of the settings you choose. The higher the quality…the more time it will take. You will have the option to tag the picture if you want to… Now you can view your scanned document or photo inside Windows Photo Viewer. If you’re happy with the look of the document, you can send it off in an email, put it on an network drive, FTP it… whatever you need to do with it. Another method is to place the document of photo you wish to scan in the scanner, open up Devices and Printers, then right-click on the scanning device and select Start Scan from the context menu. This should bypass the manufacturer screen and go directly into the New Scan window, where you can start the scan process. From the Context Menu you can also choose Scan Properties. This will allow you to test the scanner if you’re having problems with it and change some of its settings. Or you can choose Scan Profiles which allows you to use pre-selected settings, create your own, or set one as the default. Although scanning documents and photos isn’t a common occurrence as it was a few years ago, Windows 7 still includes the feature. When you need to scan a document or photo in Windows 7, this should get you started.

• Changing the action of a hyperlink in a Silverlight RichTextArea

  - by Marc Schluper

  The title of this post could also have been "Move over Hyperlink, here comes Actionlink" or "Creating interactive text in Silverlight." But alas, there can be only one. Hyperlinks are very useful. However, they are also limited because their action is fixed: browse to a URL. This may have been adequate at the start of the Internet, but nowadays, in web applications, the one thing we do not want to happen is a complete change of context. In applications we typically like a hyperlink selection to initiate an action that updates a part of the screen. For instance, if my application has a map displayed with some text next to it, the map would react to a selection of a hyperlink in the text, e.g. by zooming in on a location and displaying additional locational information in a popup. In this way, the text becomes interactive text. It is quite common that one company creates and maintains websites for many client companies. To keep maintenance cost low, it is important that the content of these websites can be updated by the client companies themselves, without the need to involve a software engineer. To accommodate this scenario, we want the author of the interactive text to configure all hyperlinks (without writing any code). In a Silverlight RichTextArea, the default action of a Hyperlink is the same as a traditional hyperlink, but it can be changed: if the Command property has a value then upon a click event this command is called with the value of the CommandParameter as parameter. How can we let the author of the text specify a command for each hyperlink in the text, and how can we let an application react properly to a hyperlink selection event? We are talking about any command here. Obviously, the application would recognize only a specific set of commands, with well defined parameters, but the approach we take here is generic in the sense that it pertains to the RichTextArea and any command. So what do we require? We wish that: As a text author, I can configure the action of a hyperlink in a (rich) text without writing code; As a text author, I can persist the action of a hyperlink with the text; As a reader of persisted text, I can click a hyperlink and the configured action will happen; As an application developer, I can configure a control to use my application specific commands. In an excellent introduction to the RichTextArea, John Papa shows (among other things) how to persist a text created using this control. To meet our requirements, we can create a subclass of RichTextArea that uses John's code and allows plugging in two command specific components: one to prompt for a command definition, and one to execute the command. Since both of these plugins are application specific, our RichTextArea subclass should not assume anything about them except their interface. public interface IDefineCommand { void Prompt(string content, // the link content Action<string, object> callback); // the method called to convey the link definition } public interface IPerformCommand : ICommand {} The IDefineCommand plugin receives the content of the link (the text visible to the reader) and displays some kind of control that allows the author to define the link. When that's done, this (possibly changed) content string is conveyed back to the RichTextArea, together with an object that defines the command to execute when the link is clicked by the reader of the published text. The IPerformCommand plugin simply implements System.Windows.Input.ICommand. Let's use MEF to load the proper plugins. In the example solution there is a project that contains rudimentary implementations of these. The IDefineCommand plugin simply prompts for a command string (cf. a command line or query string), and the IPerformCommand plugin displays a MessageBox showing this command string. An actual application using this extended RichTextArea would have its own set of commands, each having their own parameters, and hence would provide more user friendly application specific plugins. Nonetheless, in any case a command can be persisted as a string and hence the two interfaces defined above suffice. For a Visual Studio 2010 solution, see my article on The Code Project.

• They may block off Howard Street—but Oracle OpenWorld is a two-way street.

  - by Oracle Accelerate for Midsize Companies

  Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 by Jim Lein, Sr. Director, Oracle Accelerate for Midsize Companies “Engineered to Inform and Inspire”—that’s the theme of Oracle OpenWorld 2012. In early October, tens of thousands of attendees will descend on the streets of San Francisco because they share one thing in common: the desire to learn more about Oracle. You might think that’s the way we, Oracle employees, look at this event—as just another opportunity for attendees to learn about what we do. But it’s really a two way street. Every year I’m amazed by how informed and inspired I am by our customers and their companies. Midsize companies buy Oracle to grow. As part of the Oracle Accelerate for Midsize Companies team I get to talk with our partners and business leaders at growing companies almost every day, usually via phone. Oracle OpenWorld presents the perfect opportunity to meet some of them in person, in an informal setting, and in one of the most beautiful cities in the world. The stories our customers tell me about their businesses provide vivid examples of how they have overcome the challenges of managing increasingly complex global operations and growing during uncertain economic conditions. It’s no secret that my favorite session at Oracle OpenWorld (besides Larry Ellison’s keynotes and the Customer Appreciation Event, of course) is the Oracle Accelerate Customer Panel. This year we’re featuring executives from three companies who deployed Oracle ERP rapidly to support their company’s growth: Chris Powell, VP and Corporate Controller of Beats by Dr. Dre, a California based designer and manufacturer of premium headphones (sorry, no free samples), Iñaki Zuazo, CIO of Industrias Juno, a building materials provider based in Spain, Kamran Moosa, Project Coordinator for Spartan Engineering, a provider of engineering and construction support services for an LPG storage project in Texas, and That’s a pretty diverse lineup and it will be interesting to hear the perspectives of both IT and financial project stakeholders. The session, “Oracle Accelerate Customer Case Studies: Rapid Deployment of Oracle Applications”, is at 3:30 pm on Wednesday, October 3, in the Concert room at the Palace Hotel. Oracle loves our hometown of San Francisco and it’s a great place to host Oracle OpenWorld. It’s now San Francisco’s largest conference and the city closes off Howard Street to better accommodate the attendees. Some Bay Area commuters may be inconvenienced for a few days by this closure but the conference brings about $100 million into the local economy. Now that’s a two-way street.

• Your Job Search Should be More Than Just a New Year's Resolution

  - by david.talamelli

  I love the beginning of a new year, it is a great chance to refocus and either re-evaluate goals you are working to or even set new ones. I don't have any statistics to measure this but I am sure that one of the more popular new year's resolutions in the general workforce is to either get a new job or work to further develop one's career. I think this is a good idea, in today's competitive work force people should have a plan of what they want to do, what role they are after and how to get there. One common mistake I think many people make though is that a career plan shouldn't be a once a year thought. When people finish with the holiday season with their new year's resolution to find a new job fresh in their mind, you can see the enthusiasm and motivation a person has to make something happen. Emails are sent, calls are made, applications are made, networking is happening, etc..... Finding the right role that you are after however can be difficult, while it would be great if that dream role was available just at the time you happened to be looking for it - in reality this is not always the case. Job Seekers need to keep reminding themselves that while sometimes that dream job they are after is available at the same time they are looking, that also a Job search can be a difficult and long process. Many people who set out with the best of intentions in January to find a new job can soon lose interest in a job search if they do not immediately find a role. Just like the Christmas decorations are put away and the photos from New Year's are stored away - a Job Seeker's motivation may slowly decrease until that person finds themselves 12 months later in the same situation in same role and looking for that new opportunity again. Rather than just "going for it" and looking for a role in the month of January, a person's job search or career plan should be an ongoing activity and thought process that is constantly updated and evaluated over the course of the year. It can be hard to stay motivated over an extended period of time, especially when you are newly motivated and ready for that new role and the results are not immediate. Rather than letting your job search fall down the priority list and into the "too hard basket" a few ideas that may keep your enthusiasm fresh Update your resume every 6 months, even if you are not looking for a job - it is easy to forget what you have accomplished if you don't keep your details updated. Also it is good to be prepared and have a resume ready to go in case you do get an unexpected phone call for that 'dream job' you have been hoping for. Work out what you want out of your next role before you begin your job search - rather than aimlessly searching job ads or talking to people - think of the organisations or type of role you would like before you search. If you know what you are looking for it will be much easier to work out how to get there than if you do not know what you want. Don't expect immediate results once you decide to look for another job, things don't always fall into place. Timing and delivery can be important pieces of being selected for a role, companies don't hire every role in January. Have an open mind - people you meet or talk to may not result in immediate results for your job search but every connection may help you get a bit closer to what you are after . These actions will not guarantee a positive result, but in today's competitive work force every little of extra preparation and planning helps. All the best for 2011 and I hope your career plan whatever it may be is a success.

• Oracle Social Network Developer Challenge: TEAM Informatics

  - by Kellsey Ruppel

  Originally posted by Jake Kuramoto on The Apps Lab blog. Here comes another Oracle Social Network Developer Challenge entry, this one courtesy of TEAM Informatics (@teaminformatics). As their name suggests, their entry was a true team effort, featuring the work of Jon Chartrand, Deepthi Sanikommu, Dmitry Shtulman, Raghavendra Joshi, and Daniel Stitely with Wayne Boerger doing the presentation honors. Speaking of the presentation, Wayne’s laptop wouldn’t project onto the plasma we had in the OTN Lounge, but luckily, Noel (@noelportugal) had his iPad and VGA dongle in his backpack of goodies, so they were able to improvise by using the iPad camera to capture Wayne’s demo and project the video to the plasma. Code will find a way. Anyway, TEAM built Do Over, an integration with Atlassian’s JIRA, coincidentally something I’ve chatted with Rich (@rmanalan) about in the past. The basic idea is simple; integrate JIRA issues with Oracle Social Network to expand and centralize the conversation around issue resolution. In Dmitry’s words: We were able to put together a team on fairly short notice and, after batting a few ideas around, decided to pursue an integration with JIRA, an issue and project tracking tool used in-house at TEAM.  After getting to know WebCenter Social, we saw immediate benefits that a JIRA integration could bring, primarily due to the fact that JIRA only allows assignment of an issue to one person at a time.  Integrating Social would allow collaboration and issue resolution to happen right from the JIRA Issue interface. TEAM tackled a very common pain point among developers, i.e. including everyone who needs to be involved in issue resolution into a single thread. If you’ve ever fixed bugs or participated in that process, you’ll know that not everyone has access to the issue resolution system, which makes consolidating discussion time-consuming and fragmented. Why? Because we typically use email as the tool for collaboration. Oracle Social Network allows for all parties involved to work in a single, private and secure conversation, and through its RESTful Public API, information from external systems like JIRA can be brought in for context. TEAM only had time to address half the solution, but given more time, I’m sure they would have made the integration bidirectional, allowing for relevant commentary to be pushed back to JIRA, closing the loop. Here are some screenshot of their integration. #gallery-1 { margin: auto; } #gallery-1 .gallery-item { float: left; margin-top: 10px; text-align: center; width: 33%; } #gallery-1 img { border: 2px solid #cfcfcf; } #gallery-1 .gallery-caption { margin-left: 0; } When Oracle Social Network is released, TEAM will have something they use internally to work on issues, and maybe they’ll even productize their work and add it to the Atlassian Marketplace so that other JIRA users can benefit from the combination of Oracle Social Network and JIRA. Thanks to everyone at TEAM for participating in our challenge. We hope they had a good experience. Look for the details of the other entries this week. Be sure to check out a full recap from Dmitry over on the TEAM blog.

• SQL SERVER – DQS Error – Cannot connect to server – A .NET Framework error occurred during execution of user-defined routine or aggregate “SetDataQualitySessions” – SetDataQualitySessionPhaseTwo

  - by pinaldave

  Earlier I wrote a blog post about how to install DQS in SQL Server 2012. Today I decided to write a second part of this series where I explain how to use DQS, however, as soon as I started the DQS client, I encountered an error that will not let me pass through and connect with DQS client. It was a bit strange to me as everything was functioning very well when I left it last time.  The error was very big but here are the first few words of it. Cannot connect to server. A .NET Framework error occurred during execution of user-defined routine or aggregate “SetDataQualitySessions”: System.Data.SqlClient.SqlException (0×80131904): A .NET Framework error occurred during execution of user-defined routine or aggregate “SetDataQualitySessionPhaseTwo”: The error continues – here is the quick screenshot of the error. As my initial attempts could not fix the error I decided to search online and I finally received a wonderful solution from Microsoft Site. The error has happened due to latest update I had installed on .NET Framework 4. There was a  mismatch between the Module Version IDs (MVIDs) of the SQL Common Language Runtime (SQLCLR) assemblies in the SQL Server 2012 database and the Global Assembly Cache (GAC). This mismatch was to be resolved for the DQS to work properly. The workaround is specified here in detail. Scroll to subtopic 4.23 Some .NET Framework 4 Updates Might Cause DQS to Fail. The script was very much straight forward. Here are the few things to not to miss while applying workaround. Make sure DQS client is properly closed The NETAssemblies is based on your OS. NETAssemblies for 64 bit machine – which is my machine is “c:\windows\Microsoft.NET\Framework64\v4.0.30319″. If you have Winodws installed on any other drive other than c:\windows do not forget to change that in the above path. Additionally if you have 32 bit version installed on c:\windows you should use path as ”c:\windows\Microsoft.NET\Framework\v4.0.30319″ Make sure that you execute the script specified in 4.23 sections in this article in the database DQS_MAIN. Do not run this in the master database as this will not fix your error. Do not forget to restart your SQL Services once above script has been executed. Once you open the client it will work this time. Here is the script which I have bit modified from original script. I strongly suggest that you use original script mentioned 4.23 sections. However, this one is customized my own machine. /* Original source: http://bit.ly/PXX4NE (Technet) Modifications: -- Added Database context -- Added environment variable @NETAssemblies -- Main script modified to use @NETAssemblies */ USE DQS_MAIN GO BEGIN -- Set your environment variable -- assumption - Windows is installed in c:\windows folder DECLARE @NETAssemblies NVARCHAR(200) -- For 64 bit uncomment following line SET @NETAssemblies = 'c:\windows\Microsoft.NET\Framework64\v4.0.30319\' -- For 32 bit uncomment following line -- SET @NETAssemblies = 'c:\windows\Microsoft.NET\Framework\v4.0.30319\' DECLARE @AssemblyName NVARCHAR(200), @RefreshCmd NVARCHAR(200), @ErrMsg NVARCHAR(200) DECLARE ASSEMBLY_CURSOR CURSOR FOR SELECT name AS NAME FROM sys.assemblies WHERE name NOT LIKE '%ssdqs%' AND name NOT LIKE '%microsoft.sqlserver.types%' AND name NOT LIKE '%practices%' AND name NOT LIKE '%office%' AND name NOT LIKE '%stdole%' AND name NOT LIKE '%Microsoft.Vbe.Interop%' OPEN ASSEMBLY_CURSOR FETCH NEXT FROM ASSEMBLY_CURSOR INTO @AssemblyName WHILE @@FETCH_STATUS = 0 BEGIN BEGIN TRY SET @RefreshCmd = 'ALTER ASSEMBLY [' + @AssemblyName + '] FROM ''' + @NETAssemblies + @AssemblyName + '.dll' + ''' WITH PERMISSION_SET = UNSAFE' EXEC sp_executesql @RefreshCmd PRINT 'Successfully upgraded assembly ''' + @AssemblyName + '''' END TRY BEGIN CATCH IF ERROR_NUMBER() != 6285 BEGIN SET @ErrMsg = ERROR_MESSAGE() PRINT 'Failed refreshing assembly ' + @AssemblyName + '.

• C# 4.0: COM Interop Improvements

  - by Paulo Morgado

  Dynamic resolution as well as named and optional arguments greatly improve the experience of interoperating with COM APIs such as Office Automation Primary Interop Assemblies (PIAs). But, in order to alleviate even more COM Interop development, a few COM-specific features were also added to C# 4.0. Ommiting ref Because of a different programming model, many COM APIs contain a lot of reference parameters. These parameters are typically not meant to mutate a passed-in argument, but are simply another way of passing value parameters. Specifically for COM methods, the compiler allows to declare the method call passing the arguments by value and will automatically generate the necessary temporary variables to hold the values in order to pass them by reference and will discard their values after the call returns. From the point of view of the programmer, the arguments are being passed by value. This method call: object fileName = "Test.docx"; object missing = Missing.Value; document.SaveAs(ref fileName, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing); can now be written like this: document.SaveAs("Test.docx", Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value); And because all parameters that are receiving the Missing.Value value have that value as its default value, the declaration of the method call can even be reduced to this: document.SaveAs("Test.docx"); Dynamic Import Many COM methods accept and return variant types, which are represented in the PIAs as object. In the vast majority of cases, a programmer calling these methods already knows the static type of a returned object form the context of the call, but has to explicitly perform a cast on the returned values to make use of that knowledge. These casts are so common that they constitute a major nuisance. To make the developer’s life easier, it is now possible to import the COM APIs in such a way that variants are instead represented using the type dynamic which means that COM signatures have now occurrences of dynamic instead of object. This means that members of a returned object can now be easily accessed or assigned into a strongly typed variable without having to cast. Instead of this code: ((Excel.Range)(excel.Cells[1, 1])).Value2 = "Hello World!"; this code can now be used: excel.Cells[1, 1] = "Hello World!"; And instead of this: Excel.Range range = (Excel.Range)(excel.Cells[1, 1]); this can be used: Excel.Range range = excel.Cells[1, 1]; Indexed And Default Properties A few COM interface features are still not available in C#. On the top of the list are indexed properties and default properties. As mentioned above, these will be possible if the COM interface is accessed dynamically, but will not be recognized by statically typed C# code. No PIAs – Type Equivalence And Type Embedding For assemblies indentified with PrimaryInteropAssemblyAttribute, the compiler will create equivalent types (interfaces, structs, enumerations and delegates) and embed them in the generated assembly. To reduce the final size of the generated assembly, only the used types and their used members will be generated and embedded. Although this makes development and deployment of applications using the COM components easier because there’s no need to deploy the PIAs, COM component developers are still required to build the PIAs.

• Kanban Tools Review

  - by GeekAgilistMercenary

  The first two sessions on Sunday were Collaboration and why it is so hard and the following, which was a perfect following session was on Kanban.  While in that second session two online Saas Style Tools were mentioned; AgileZen and Leankit.  I decided right then and there that I would throw together some first impressions and setup some sample projects.  I did this by setting up an account and creating the projects. Agile Zen Account Creation Setting up the initial account required an e-mail verification, which is understandable.  Within a few seconds it was mailed out and I was logged in. Setting Up the Kanban Board The initial setup of the board was pretty easy.  I maybe clicked around an extra few times, but overall everything I needed to use the tool was immediately available.  The representation of everything was very similar to what one expects in a real Kanban Board too.  This is a HUGE plus, especially if a team is smart and places this tool in a centrally viewable area to allow for visibility. Each of the board items is just like a post it, being blue, grey, green, pink, or one of another few colors.  Dragging them onto each swim lane on the board was flawless, making changes through the work super easy and intuitive. The other thing I really liked about AgileZen is that the Kanban Board had the swim lanes setup immediately.  One can change them, but when you know you immediately need a Ready Lane, Working Lane, and a Complete Lane it is nice to just have them right in front of you in the interface.  In addition, the Backlog is simply a little tab on the left hand side.  This is perfect for the Backlog Queue.  Out of the way, with the focus on the primary items. Once  I got the items onto the board I was easily able to get back to the actual work at hand versus playing around with the tool.  The fact that it was so easy to use, fast and easy UX, and overall a great layout put me back to work on things I needed to do versus sitting a playing with the tool.  That, in the end is the key to using these tools. LeanKit Kanban Account Creation Setting up the account got me straight into the online tool.  This I thought was pretty cool. Setting Up the Kanban Board Setting up the Kanban Board within Leankit was a bit of trouble.  There were multiple UX issues in regard to process and intuitiveness.  The Leankit basically forces one to design the whole board first, making no assumptions about how the board should look.  The swim lanes in my humble opinion should be setup immediately without any manipulation with the most common lanes;  ready, working, and complete. The other UX hiccup that I had a problem with is that as soon as I managed to get the swim lanes into place, I wanted to remove the redundant Backlog Lane.  The Backlog Lane, or Backlog Bucket should be somewhere that I accidentally added as a lane.  Then on top of that I screwed up and added an item inside the lane, which then prevented me from deleting the lane.  I had to go back out of the lane manipulation, remove the item, and then remove the excess lane.  Summary Leankit wasn't a bad interface, it just wasn't as good as AgileZen.  The AgileZen interface was just better UX design overall.  AgileZen also presents a much better user interface graphical design all together.  It is much closer to what the Kanban Board would look like if it were a physical Kanban Board.  Since one of the HUGE reasons for Kanban is to increase visibility, the fact the design is similar to what a real Kanban Board is actually a pretty big deal. This is an image (click for larger) that shows the two Kanban Boards side by side.  The one on the left is AgileZen and the right is Leankit. Original Entry

• From NaN to Infinity...and Beyond!

  - by Tony Davis

  It is hard to believe that it was once possible to corrupt a SQL Server Database by storing perfectly normal data values into a table; but it is true. In SQL Server 2000 and before, one could inadvertently load invalid data values into certain data types via RPC calls or bulk insert methods rather than DML. In the particular case of the FLOAT data type, this meant that common 'special values' for this type, namely NaN (not-a-number) and +/- infinity, could be quite happily plugged into the database from an application and stored as 'out-of-range' values. This was like a time-bomb. When one then tried to query this data; the values were unsupported and so data pages containing them were flagged as being corrupt. Any query that needed to read a column containing the special value could fail or return unpredictable results. Microsoft even had to issue a hotfix to deal with failures in the automatic recovery process, caused by the presence of these NaN values, which rendered the whole database inaccessible! This problem is history for those of us on more current versions of SQL Server, but its ghost still haunts us. Recently, for example, a developer on Red Gate’s SQL Response team reported a strange problem when attempting to load historical monitoring data into a SQL Server 2005 database via the C# ADO.NET provider. The ratios used in some of their reporting calculations occasionally threw out NaN or infinity values, and the subsequent attempts to load these values resulted in a nasty error. It turns out to be a different manifestation of the same problem. SQL Server 2005 still does not fully support the IEEE 754 standard for floating point numbers, in that the FLOAT data type still cannot handle NaN or infinity values. Instead, they just added validation checks that prevent the 'invalid' values from being loaded in the first place. For people migrating from SQL Server 2000 databases that contained out-of-range FLOAT (or DATETIME etc.) data, to SQL Server 2005, Microsoft have added to the latter's version of the DBCC CHECKDB (or CHECKTABLE) command a DATA_PURITY clause. When enabled, this will seek out the corrupt data, but won’t fix it. You have to do this yourself in what can often be a slow, painful manual process. Our development team, after a quizzical shrug of the shoulders, simply decided to represent NaN and infinity values as NULL, and move on, accepting the minor inconvenience of not being able to tell them apart. However, what of scientific, engineering and other applications that really would like the luxury of being able to both store and access these perfectly-reasonable floating point data values? The sticking point seems to be the stipulation in the IEEE 754 standard that, when NaN is compared to any other value including itself, the answer is "unequal" (i.e. FALSE). This is clearly different from normal number comparisons and has repercussions for such things as indexing operations. Even so, this hardly applies to infinity values, which are single definite values. In fact, there is some encouraging talk in the Connect note on this issue that they might be supported 'in the SQL Server 2008 timeframe'. If didn't happen; SQL 2008 doesn't support NaN or infinity values, though one could be forgiven for thinking otherwise, based on the MSDN documentation for the FLOAT type, which states that "The behavior of float and real follows the IEEE 754 specification on approximate numeric data types". However, the truth is revealed in the XPath documentation, which states that "…float (53) is not exactly IEEE 754. For example, neither NaN (Not-a-Number) nor infinity is used…". Is it really so hard to fix this problem the right way, and properly support in SQL Server the IEEE 754 standard for the floating point data type, NaNs, infinities and all? Oracle seems to have managed it quite nicely with its BINARY_FLOAT and BINARY_DOUBLE types, so it is technically possible. We have an enterprise-class database that is marketed as being part of an 'integrated' Windows platform. Absurdly, we have .NET and XPath libraries that fully support the standard for floating point numbers, and we can't even properly store these values, let alone query them, in the SQL Server database! Cheers, Tony.

• What’s the use of code reuse?

  - by Tony Davis

  All great developers write reusable code, don’t they? Well, maybe, but as with all statements regarding what “great” developers do or don’t do, it’s probably an over-simplification. A novice programmer, in particular, will encounter in the literature a general assumption of the importance of code reusability. They spend time worrying about DRY (don’t repeat yourself), moving logic into specific “helper” modules that they can then reuse, agonizing about the minutiae of the class structure, inheritance and interface design that will promote easy reuse. Unfortunately, writing code specifically for reuse often leads to complicated object hierarchies and inheritance models that are anything but reusable. If, instead, one strives to write simple code units that are highly maintainable and perform a single function, in a concise, isolated fashion then the potential for reuse simply “drops out” as a natural by-product. Programmers, of course, care about these principles, about encapsulation and clean interfaces that don’t expose inner workings and allow easy pluggability. This is great when it helps with the maintenance and development of code but how often, in practice, do we actually reuse our code? Most DBAs and database developers are familiar with the practical reasons for the limited opportunities to reuse database code and its potential downsides. However, surely elsewhere in our code base, reuse happens often. After all, we can all name examples, such as date/time handling modules, which if we write with enough care we can plug in to many places. I spoke to a developer just yesterday who looked me in the eye and told me that in 30+ years as a developer (a successful one, I’d add), he’d never once reused his own code. As I sat blinking in disbelief, he explained that, of course, he always thought he would reuse it. He’d often agonized over its design, certain that he was creating code of great significance that he and other generations would reuse, with grateful tears misting their eyes. In fact, it never happened. He had in his head, most of the algorithms he needed and would simply write the code from scratch each time, refining the algorithms and tailoring the code to meet the specific requirements. It was, he said, simply quicker to do that than dig out the old code, check it, correct the mistakes, and adapt it. Is this a common experience, or just a strange anomaly? Viewed in a certain light, building code with a focus on reusability seems to hark to a past age where people built cars and music systems with the idea that someone else could and would replace and reuse the parts. Technology advances so rapidly that the next time you need the “same” code, it’s likely a new technique, or a whole new language, has emerged in the meantime, better equipped to tackle the task. Maybe we should be less fearful of the idea that we could write code well suited to the system requirements, but with little regard for reuse potential, and then rewrite a better version from scratch the next time.

• Logging WebSocket Frames using Chrome Developer Tools, Net-internals and Wireshark (TOTD #184)

  - by arungupta

  TOTD #183 explained how to build a WebSocket-driven application using GlassFish 4. This Tip Of The Day (TOTD) will explain how do view/debug on-the-wire messages, or frames as they are called in WebSocket parlance, over this upgraded connection. This blog will use the application built in TOTD #183. First of all, make sure you are using a browser that supports WebSocket. If you recall from TOTD #183 then WebSocket is combination of Protocol and JavaScript API. A browser supporting WebSocket, or not, means they understand your web pages with the WebSocket JavaScript. caniuse.com/websockets provide a current status of WebSocket support in different browsers. Most of the major browsers such as Chrome, Firefox, Safari already support WebSocket for the past few versions. As of this writing, IE still does not support WebSocket however its planned for a future release. Viewing WebSocket farmes require special settings because all the communication happens over an upgraded HTTP connection over a single TCP connection. If you are building your application using Java, then there are two common ways to debug WebSocket messages today. Other language libraries provide different mechanisms to log the messages. Lets get started! Chrome Developer Tools provide information about the initial handshake only. This can be viewed in the Network tab and selecting the endpoint hosting the WebSocket endpoint. You can also click on "WebSockets" on the bottom-right to show only the WebSocket endpoints. Click on "Frames" in the right panel to view the actual frames being exchanged between the client and server. The frames are not refreshed when new messages are sent or received. You need to refresh the panel by clicking on the endpoint again. To see more detailed information about the WebSocket frames, you need to type "chrome://net-internals" in a new tab. Click on "Sockets" in the left navigation bar and then on "View live sockets" to see the page. Select the box with the address to your WebSocket endpoint and see some basic information about connection and bytes exchanged between the client and the endpoint. Clicking on the blue text "source dependency ..." shows more details about the handshake. If you are interested in viewing the exact payload of WebSocket messages then you need a network sniffer. These tools are used to snoop network traffic and provide a lot more details about the raw messages exchanged over the network. However because they provide lot more information so they need to be configured in order to view the relevant information. Wireshark (nee Ethereal) is a pretty standard tool for sniffing network traffic and will be used here. For this blog purpose, we'll assume that the WebSocket endpoint is hosted on the local machine. These tools do allow to sniff traffic across the network though. Wireshark is quite a comprehensive tool and we'll capture traffic on the loopback address. Start wireshark, select "loopback" and click on "Start". By default, all traffic information on the loopback address is displayed. That includes tons of TCP protocol messages, applications running on your local machines (like GlassFish or Dropbox on mine), and many others. Specify "http" as the filter in the top-left. Invoke the application built in TOTD #183 and click on "Say Hello" button once. The output in wireshark looks like Here is a description of the messages exchanged: Message #4: Initial HTTP request of the JSP page Message #6: Response returning the JSP page Message #16: HTTP Upgrade request Message #18: Upgrade request accepted Message #20: Request favicon Message #22: Responding with favicon not found Message #24: Browser making a WebSocket request to the endpoint Message #26: WebSocket endpoint responding back You can also use Fiddler to debug your WebSocket messages. How are you viewing your WebSocket messages ? Here are some references for you: JSR 356: Java API for WebSocket - Specification (Early Draft) and Implementation (already integrated in GlassFish 4 promoted builds) TOTD #183 - Getting Started with WebSocket in GlassFish Subsequent blogs will discuss the following topics (not necessary in that order) ...

• Bancassurers Seek IT Solutions to Support Distribution Model

  - by [email protected]

  Oracle Insurance's director of marketing for EMEA, John Sinclair, attended the third annual Bancassurance Forum in Vienna last month. He reports that the outlook for bancassurance in EMEA remains positive, despite changing market conditions that have led a number of bancassurers to re-examine their business models. Vienna is at the crossroads between mature Western European markets, where bancassurance is now an established best practice, and more recently tapped Eastern European markets that offer the greatest growth potential. Attendance at the Bancassurance Forum was good, with 87 bancassurance attendees, most in very senior positions in the industry. The conference provided the chance for a lively discussion among bancassurers looking to keep abreast of the latest trends in one of Europe's most successful distribution models for insurance. Even under normal business conditions, there is a great demand for best practice sharing within the industry as there is no standard formula for success.  Each company has to chart its own course and choose the strategies for sales, products development and the structure of ownership that make sense for their business, and as soon as they get it right bancassurers need to adapt the mix to keep up with ever changing regulations, completion and economic conditions.  To optimize the overall relationship between banking and insurance for mutual benefit, a balance needs to be struck between potentially conflicting interests. The banking side of the house is looking for greater wallet share from its customers and the ability to increase profitability by bundling insurance products with higher margins - especially in light of the recent economic crisis, where margins for traditional banking products are low and completion high. The insurance side of the house seeks access to new customers through a complementary distribution channel that is efficient and cost effective. To make the relationship work, it is important that both sides of the same house forge strategic and long term relationships - irrespective of whether the underlying business model is supported by a distribution agreement, cross-ownership or other forms of capital structure. However, this third annual conference was not held under normal business conditions. The conference took place in challenging, yet interesting times. ING's forced spinoff of its insurance operations under pressure by the EU Commission and the troubling losses suffered by Allianz as a result of the Dresdner bank sale were fresh in everyone's mind. One year after markets crashed, there is now enough hindsight to better understand the implications for bancassurance and best practices that are emerging to deal with them. The loan-driven business that has been crucial to bancassurance up till now evaporated during the crisis, leaving bancassurers grappling with how to change their overall strategy from a loan-driven to a more diversified model.  Attendees came to the conference to learn what strategies were working - not only to cope with the market shift, but to take advantage of it as markets pick up. Over the course of 14 customer case studies and numerous analyst presentations, topical issues ranging from getting the business model right to the impact on capital structuring of Solvency II were debated openly. Many speakers alluded to the need to specifically design insurance products with the banking distribution channel in mind, which brings with it specific requirements such as a high degree of standardization to achieve efficiency and reduce training costs. Moreover, products must be engineered to suit end consumers who consider banks a one-stop shop. The importance of IT to the successful implementation of bancassurance strategies was a theme that surfaced regularly throughout the conference.  The cross-selling opportunity - that will ultimately determine the success or failure of any bancassurance model - can only be fully realized through a flexible IT architecture that enables banking and insurance processes to be integrated and presented to front-line staff through a common interface. However, the reality is that most bancassurers have legacy IT systems, which constrain the businesses' ability to implement new strategies to maintaining competitiveness in turbulent times. My colleague Glenn Lottering, who chaired the conference, believes that the primary opportunities for bancassurers to extract value from their IT infrastructure investments lie in distribution management, risk management with the advent of Solvency II, and achieving operational excellence. "Oracle is ideally suited to meet the needs of bancassurance," Glenn noted, "supplying market-leading software for both banking and insurance. Oracle provides adaptive systems that let customers easily integrate hybrid business processes from both worlds while leveraging existing IT infrastructure." Overall, the consensus at the conference was that the outlook for bancassurance in EMEA remains positive, despite changing market conditions that have led a number of bancassurers to re-examine their business models. John Sinclair is marketing director for Oracle Insurance in EMEA. He has more than 20 years of experience in insurance and financial services.

• Converting an Oracle VM VirtualBox VM into an Oracle VM Server image

  - by wim.coekaerts

  As we are working on tighter seemless moving of VM's between the 2 products, here are a few simple steps to convert an existing Oracle VM VirtualBox image over. Steps involved to make it easy/straightforward : (1) When creating a VM in Virtualbox, using Oracle Linux as an example, make sure that /etc/fstab only uses labels. Do not use hardcoded device names. instead of an entry /dev/sda1 /u01 ext3 defaults 1 1 use LABEL=foo /u01 ext3 defaults 1 1 for more info on labels : man e2label or use a logical volume /dev/VolGroup00/LVfoo /u01 ext3 defaults 1 1 Doing so will make it easier to have an OS boot up on a different hypervisor with potentially different device names. For instance, the VirtualBox VM might expose a scsi driver while in Oracle VM Server you might end up with an ide disk, this then changes /dev/sda to /dev/hda. (2) If you have a VM created that you want to convert, then shut down the VM in VirtualBox and convert the image files : go the the directory that contains your HardDisk image files (.VirtualBox/HardDisks/* as an example) for each of the virtual disks run the following command : VBoxManage clonehd virtualdiskfilename.vdi system.img --format raw where virtualdiskfilename.vdi is the original VBox VM file (this can also be a vmdk file) and system.img is the name of the virtualdisk for Oracle VM. this can be any filename as well, I typically use system.img to specify the boot disk (as is common for Oracle VM template creation) (3) create a vm.cfg To run a VM converted from VirtualBox, you have to create a vm.cfg for Oracle VM server that creates an HVM guest. The easiest is to use a simple hvm vm.cfg and change it for your vm. I have an example here : acpi = 1 apic = 1 builder = 'hvm' device_model = '/usr/lib/xen/bin/qemu-dm' disk = ['file:system.img,hda,w', 'file:oracle.img,hdb,w',',hdc:cdrom,r',] kernel = '/usr/lib/xen/boot/hvmloader' memory = '1024' name = 'vmname' on_crash = 'restart' on_reboot = 'restart' pae = 1 serial = 'pty' timer_mode = '0' usbdevice = 'tablet' vcpus = 1 vif = ['bridge=xenbr0,type=ioemu'] vif_other_config = [] vnc = 1 vncconsole = 1 vnclisten = '0.0.0.0' vncpasswd = '' vncunused = 1 If you take the above vm.cfg, all you need to do - modify disk = (add your virtual disks in there) - modify memory = (amount of memory your VM needs) - modify name = (enter a name for your VM here) - modify vif = (might want to replace bridge=xenbr0 to the bridge you want to use) if you want more than 1 vcpu or other changes of course you have to make those as well. (4) copy this set of files onto your Oracle VM server or onto a webserver in a subdirectory and import the template through Oracle VM Manager. You can also just start the vm using xm create vm.cfg if you like. And that's it. As I said, we are working on automation around all this but it is relatively trivial to convert VM's over as long as you take the basic issues into account. Primarily the set up of the filesystems and the use of labels in /etc/fstab. There are other potential things to look at, such as network config. If you want to make that part clean then prior to shutting down the VM change /etc/modprobe.conf and/or add the mac address of the VM into the vm.cfg in the vifs line. The good thing, at least with Linux, is that even tho the virtual hardware changes, Linux will deal with it just fine (e1000 vs 8139 realtek, ide vs scsi etc). hope this helps.

• Know Your Audience, And/Or Your Customer

  - by steve.diamond

  Yesterday I gave an internal presentation to about 20 Oracle employees on "messaging," not messaging technology, but embarking on the process of building messages. One of the elements I covered was the importance of really knowing and understanding your audience. As a humorous reference I included two side-by-side photos of Oakland A's fans and Oakland Raiders fans. The Oakland A's fans looked like happy-go-lucky drunk types. The Oakland Raiders fans looked like angry extras from a low budget horror flick. I then asked my presentation attendees what these two groups had in common. Here's what I heard. --They're human (at least I THINK they're human). --They're from Oakland. --They're sports fans. After that, it was anyone's guess. A few days earlier we were putting the finishing touches on a sales presentation for one of our product lines. We had included an upfront "lead in" addressing how the economy is improving, yet that doesn't mean sales executives will have any more resources to add to their teams, invest in technology, etc. This "lead in" included miscellaneous news article headlines and statistics validating the slowly improving economy. When we subjected this presentation to internal review two days ago, this upfront section in particular was scrutinized. "Is the economy really getting better? I (exclamation point) don't think it's really getting better. Haven't you seen the headlines coming out of Greece and Europe?" Then the question TO ME became, "Who will actually be in the audience that sees and hears this presentation? Will s/he be someone like me? Or will s/he be someone like the critic who didn't like our lead-in?" We took the safe route and removed that lead in. After all, why start a "pitch" with a component that is arguably subjective? What if many of our audience members are individuals at organizations still facing a strong headwind? For reasons I won't go into here, it was the right decision to make. The moral of the story: Make sure you really know your audience. Harness the wisdom of the information your organization's CRM systems collect to get that fully informed "customer view." Conduct formal research. Conduct INFORMAL research. Ask lots of questions. Study industries and scenarios that have nothing to do with yours to see "how they do it." Stop strangers in coffee shops and on the street...seriously. Last week I caught up with an old friend from high school who recently retired from a 25 year career with the USMC. He said, "I can learn something from every single person I come into contact with." What a great way of approaching the world. Then, think about and write down what YOU like and dislike as a customer. But also remember that when it comes to your company's products, you are most likely NOT the customer, so don't go overboard in superimposing your own world view. Approaching the study of customers this way adds rhyme, reason and CONTEXT to lengthy blog posts like this one. Know your audience.

• Three Easy Ways of Providing Feedback to the Oracle AutoVue Team

  - by Celine Beck

  Customer feedback is essential in helping us deliver best-in-class Enterprise Visualization solutions which are centered around real-world usage. As the Oracle AutoVue Product Management team is busy prioritizing the next round of improvements, enhancements and new innovation to the AutoVue platform, I thought it would be a good idea to provide our blog-readers with a recap of how best to provide product feedback to the AutoVue Product Management team. This gives you the opportunity to help shape our future agenda and make our solutions better for you. Enterprise Visualization Special Interest Group (EV SIG): the AutoVue EV SIG is a customer-driven initiative that has recently been created to share knowledge and information between members and discuss common and best practices around Enterprise Visualization. The EV SIG also serves as a mechanism for establishing and communicating to AutoVue Product Management users’ collective priorities for the future development, direction and enhancement of the AutoVue product family with the objective of ensuring their continuous improvement. Essentially, EV SIG members meet in order to share and prioritize feedback and use this input to begin dialog with the AutoVue Product Management team on what they deem to be the most important improvements to Enterprise Visualization solutions. The AutoVue EV SIG is by far the best platform for sharing and relaying feedback to our Product Strategy / Management team regarding general product enhancements, industry-specific scenarios, new use cases, usability, support, deployability, etc, and helping us shape the future direction of Enterprise Visualization solutions. We strongly encourage ALL our customers to sign up for the SIG;  here is how you can do so: Sign up for the EVSIG mailing list b.    Visit the group’s website c.    Contact Dennis Walker at Harris Corporation directly should you have any questions: dwalke22-AT-harris-DOT-com Customer / Partner Advisory Boards: The AutoVue Product Strategy / Management team also periodically runs Customer and Partner Advisory Boards. These invitation-only events bring together individuals chosen from Oracle AutoVue’s top customers that are using AutoVue at the enterprise level, as well as strategic partners.  The idea here is to establish open lines of communication between top customers and partners and the Oracle AutoVue Product Strategy team, help us communicate AutoVue’s product direction, share perspectives on today and tomorrow’s challenges and needs for Enterprise Visualization, and validate that proposed additions to the product are valid industry solutions. Our next Customer / Partner Advisory Board will be held in San Francisco during Oracle Open World, please contact your account manager to find out more about the CAB Members’ nomination process. Enhancement Requests:  Enhancement requests are request logged by customers or partners with Product Development for a feature that is not currently available in Oracle AutoVue. Enhancement requests (ER) can be logged easily via the My Oracle Support portal. This is the best way to share feedback with us at the functionality level; for instance if you would like to see a new format supported in AutoVue or make suggestions as per how certain functionality can be improved or should behave. Once the ER is logged, it is then evaluated by Product Management based on feasibility, product adequation and business justification. Product Management then decides whether to consider this ER for future release or not. What helps accelerate the process is hearing from a large number of customers who urgently need a particular feature or configuration. Hence the importance of logging Metalink Service Requests, and describing in details your business expectations. You can include key milestones dates and justifications as to why this request is important and the benefits your organization stands to gain should this request be accepted. Again, feedback from customers and partners is critical to ensure we offer solutions that have the biggest impact on customers’ business processes and day-to-day operations. All feedback is welcome,. So please don’t be shy!

• Clone a Hard Drive Using an Ubuntu Live CD

  - by Trevor Bekolay

  Whether you’re setting up multiple computers or doing a full backup, cloning hard drives is a common maintenance task. Don’t bother burning a new boot CD or paying for new software – you can do it easily with your Ubuntu Live CD. Not only can you do this with your Ubuntu Live CD, you can do it right out of the box – no additional software needed! The program we’ll use is called dd, and it’s included with pretty much all Linux distributions. dd is a utility used to do low-level copying – rather than working with files, it works directly on the raw data on a storage device. Note: dd gets a bad rap, because like many other Linux utilities, if misused it can be very destructive. If you’re not sure what you’re doing, you can easily wipe out an entire hard drive, in an unrecoverable way. Of course, the flip side of that is that dd is extremely powerful, and can do very complex tasks with little user effort. If you’re careful, and follow these instructions closely, you can clone your hard drive with one command. We’re going to take a small hard drive that we’ve been using and copy it to a new hard drive, which hasn’t been formatted yet. To make sure that we’re working with the right drives, we’ll open up a terminal (Applications > Accessories > Terminal) and enter in the following command sudo fdisk –l We have two small drives, /dev/sda, which has two partitions, and /dev/sdc, which is completely unformatted. We want to copy the data from /dev/sda to /dev/sdc. Note: while you can copy a smaller drive to a larger one, you can’t copy a larger drive to a smaller one with the method described below. Now the fun part: using dd. The invocation we’ll use is: sudo dd if=/dev/sda of=/dev/sdc In this case, we’re telling dd that the input file (“if”) is /dev/sda, and the output file (“of”) is /dev/sdc. If your drives are quite large, this can take some time, but in our case it took just less than a minute. If we do sudo fdisk –l again, we can see that, despite not formatting /dev/sdc at all, it now has the same partitions as /dev/sda.  Additionally, if we mount all of the partitions, we can see that all of the data on /dev/sdc is now the same as on /dev/sda. Note: you may have to restart your computer to be able to mount the newly cloned drive. And that’s it…If you exercise caution and make sure that you’re using the right drives as the input file and output file, dd isn’t anything to be scared of. Unlike other utilities, dd copies absolutely everything from one drive to another – that means that you can even recover files deleted from the original drive in the clone!

• Building vs. Buying a Master Data Management Solution

  - by david.butler(at)oracle.com

  Many organizations prefer to build their own MDM solutions. The argument is that they know their data quality issues and their data better than anyone. Plus a focused solution will cost less in the long run then a vendor supplied general purpose product. This is not unreasonable if you think of MDM as a point solution for a particular data quality problem. But this approach carries significant risk. We now know that organizations achieve significant competitive advantages when they deploy MDM as a strategic enterprise wide solution: with the most common best practice being to deploy a tactical MDM solution and grow it into a full information architecture. A build your own approach most certainly will not scale to a larger architecture unless it is done correctly with the larger solution in mind. It is possible to build a home grown point MDM solution in such a way that it will dovetail into broader MDM architectures. A very good place to start is to use the same basic technologies that Oracle uses to build its own MDM solutions. Start with the Oracle 11g database to create a flexible, extensible and open data model to hold the master data and all needed attributes. The Oracle database is the most flexible, highly available and scalable database system on the market. With its Real Application Clusters (RAC) it can even support the mixed OLTP and BI workloads that represent typical MDM data access profiles. Use Oracle Data Integration (ODI) for batch data movement between applications, MDM data stores, and the BI layer. Use Oracle Golden Gate for more real-time data movement. Use Oracle's SOA Suite for application integration with its: BPEL Process Manager to orchestrate MDM connections to business processes; Identity Management for managing users; WS Manager for managing web services; Business Intelligence Enterprise Edition for analytics; and JDeveloper for creating or extending the MDM management application. Oracle utilizes these technologies to build its MDM Hubs.  Customers who build their own MDM solution using these components will easily migrate to Oracle provided MDM solutions when the home grown solution runs out of gas. But, even with a full stack of open flexible MDM technologies, creating a robust MDM application can be a daunting task. For example, a basic MDM solution will need: a set of data access methods that support master data as a service as well as direct real time access as well as batch loads and extracts; a data migration service for initial loads and periodic updates; a metadata management capability for items such as business entity matrixed relationships and hierarchies; a source system management capability to fully cross-reference business objects and to satisfy seemingly conflicting data ownership requirements; a data quality function that can find and eliminate duplicate data while insuring correct data attribute survivorship; a set of data quality functions that can manage structured and unstructured data; a data quality interface to assist with preventing new errors from entering the system even when data entry is outside the MDM application itself; a continuing data cleansing function to keep the data up to date; an internal triggering mechanism to create and deploy change information to all connected systems; a comprehensive role based data security system to control and monitor data access, update rights, and maintain change history; a flexible business rules engine for managing master data processes such as privacy and data movement; a user interface to support casual users and data stewards; a business intelligence structure to support profiling, compliance, and business performance indicators; and an analytical foundation for directly analyzing master data. Oracle's pre-built MDM Hub solutions are full-featured 3-tier Internet applications designed to participate in the full Oracle technology stack or to run independently in other open IT SOA environments. Building MDM solutions from scratch can take years. Oracle's pre-built MDM solutions can bring quality data to the enterprise in a matter of months. But if you must build, at lease build with the world's best technology stack in a way that simplifies the eventual upgrade to Oracle MDM and to the full enterprise wide information architecture that it enables.

• SQL SERVER – Understanding XML – Contest Win Joes 2 Pros Combo (USD 198) – Day 5 of 5

  - by pinaldave

  August 2011 we ran a contest where every day we give away one book for an entire month. The contest had extreme success. Lots of people participated and lots of give away. I have received lots of questions if we are doing something similar this month. Absolutely, instead of running a contest a month long we are doing something more interesting. We are giving away USD 198 worth gift every day for this week. We are giving away Joes 2 Pros 5 Volumes (BOOK) SQL 2008 Development Certification Training Kit every day. One copy in India and One in USA. Total 2 of the giveaway (worth USD 198). All the gifts are sponsored from the Koenig Training Solution and Joes 2 Pros. The books are available here Amazon | Flipkart | Indiaplaza How to Win: Read the Question Read the Hints Answer the Quiz in Contact Form in following format Question Answer Name of the country (The contest is open for USA and India residents only) 2 Winners will be randomly selected announced on August 20th. Question of the Day: Is following XML a well formed XML Document? <?xml version=”1.0″?> <address> <firstname>Pinal</firstname> <lastname>Dave</lastname> <title>Founder</title> <company>SQLAuthority.com</company> </address> a) Yes b) No c) I do not know Query Hints: BIG HINT POST A common observation by people seeing an XML file for the first time is that it looks like just a bunch of data inside a text file. XML files are text-based documents, which makes them easy to read.  All of the data is literally spelled out in the document and relies on a just a few characters (<, >, =) to convey relationships and structure of the data.  XML files can be used by any commonly available text editor, like Notepad. Much like a book’s Table of Contents, your first glance at well-formed XML will tell you the subject matter of the data and its general structure. Hints appearing within the data help you to quickly identify the main theme (similar to book’s subject), its headers (similar to chapter titles or sections of a book), data elements (similar to a book’s characters or chief topics), and so forth. We’ll learn to recognize and use the structural “hints,” which are XML’s markup components (e.g., XML tags, root elements). The XML Raw and Auto modes are great for displaying data as all attributes or all elements – but not both at once. If you want your XML stream to have some of its data shown in attributes and some shown as elements, then you can use the XML Path mode. If you are using an XML Path stream, then by default all values will be shown as elements. However, it is possible to pick one or more elements to be shown with an attribute(s) as well. Additional Hints: I have previously discussed various concepts from SQL Server Joes 2 Pros Volume 5. SQL Joes 2 Pros Development Series – OpenXML Options SQL Joes 2 Pros Development Series – Preparing XML in Memory SQL Joes 2 Pros Development Series – Shredding XML SQL Joes 2 Pros Development Series – Using Root With Auto XML Mode SQL Joes 2 Pros Development Series – Using Root With Auto XML Mode SQL Joes 2 Pros Development Series – What is XML?

• SQL SERVER – #TechEdIn – Presenting Tomorrow on SQL Server Misconception and Resolution with Vinod Kumar at TechEd India 2012

  - by pinaldave

  I am excited AND nervous at the same time. I am going to present a very interesting topic tomorrow at an SQL Server track in India. This will be my fourth time presenting at TechEd India. So far, I have received so much feedback about this one session. It seems like every single person out there has their own wishes and requests. I am sure that it is going to very challenging experience to satisfy everyone who attends the event through my presentation. Surprise Element Here is the good news: I am going to co-present this session with Vinod Kumar, my long time friend and co-worker. We have known each other for almost four years now, but this is the very first time that we are going to present together on the big stage of TechEd.  When there are more than two presenters, the usual trick is to practice the session multiple times and know exactly what each other is going to present and talk about. However, there’s a catch – we decided to make it different this time and have shared nothing to each other regarding what exactly we are going to present. This makes everything extremely interesting as each of us will be as clueless as the audience when other person is going to talk. Action Item Here are a few of the action items for all of those who are going to attend this session. Vinod and I will be present at the venue 15 minutes before the session. Do come in early and talk with us. We would be glad to talk with you and see if either of us can accommodate your suggestion in our session. If we do, we will give a surprise gift for you. As discussed, this session is going to be a unique two-presenter session. You will have chance to take a side with one speaker and stump the other speaker. Come early to decide which speaker you want to cheer during the session. Quiz and Goodies By now, you must have figured out that this session is going to be an extremely interactive session. We need your support through your active participation. We will have some really brain-twisting quiz line up just for you. You will have to take part and win surprises from us! Trust me. If you get it right, we will give you something which can help you learn more! We will have a quiz on Twitter as well. We will ask a question in person and you will be able to participate on Twitter. 10 – Demos As I said, both of us do not know what each other is going to present, but there are few things which we know very well. We have 10 demos and 6 slides. I think this is going to be an exciting demo marathon. Trust me, you will love it and the taste of this session will be in your mouth till the next TechEd. Session Details Title: SQL Server Misconceptions and Resolution – A Practical Perspective (Add to Calendar) Abstract: “The earth is flat”! – An ancient common misconception, which has been proven incorrect as we progressed in modern times. In this session, we will see various database misconceptions prevailing and their resolutions with the aid of the demos. In this unique session, the audience will be a part of the conversation and resolution. Date and Time: March 21, 2012, 15:15 to 16:15 Location: Hotel Lalit Ashok - Kumara Krupa High Grounds, Bengaluru – 560001, Karnataka, India.
