UCM 11g is 4 days old!

- by kyle.hatlestad

Ok...so I missed posting a blog entry when UCM 11g and the entire ECM suite released on Tuesday. Hopefully you've already seen the announcements on any number of the Oracle ECM blogs out there such as ECM Alerts, Fusion ECM, bex huff, or C4. So I won't bore you with the same talking points like 179 million check-ins per day or 124 web site page hits per second. Instead, I thought I'd show some screenshots of the new features in UCM and URM 11g. WebLogic Server and Enterprise Manager So probably the biggest change in 11g is UCM and URM now run on top of the WebLogic Server application server. This is a huge step as ECM is now on a standard platform with the rest of Oracle Fusion Middleware which makes installation, configuration, and integration consistent among all the products. From a feature perspective, it's also beneficial because it's now integrated with Oracle Enterprise Manager. Enterprise Manager provides a lot of provisioning control over servers as well as performance monitoring and access to logs and debugging information. Desktop Integration Suite Desktop Integration Suite got a complete overhaul for 11g. It exposes a lot more features within Windows Explorer such as saved searches, workflow queue, and checked-out items. It also now support metadata pop-up screens to let users fill in additional metadata when they drag-n-drop files in! And the integration within Office applications has changed significantly by introducing a dedicated UCM menu to do open, save, compare, etc. Site Studio for External Applications In UCM Site Studio 10gR4, a major architectural shift was introduced which brought several new objects such as elements, region definitions, region templates, and placeholder definitions. This truly separated the content from the display and from the definition. It also allowed separation of the content from needing to be rendered on a complete Site Studio page. Well, the new Site Studio for External Applications takes advantage of that architecture and introduces pre-built tags and plug-ins to JDeveloper to allow to go from simply adding a content area to your web application page to building an entire web site, just like you would have done in Site Studio Designer. In addition to these changes, enhancements to the core Site Studio have been added as well. One of the big ones is called Designer Mode which allows power-users to bypass the standard rules defined by the placeholder definition or template and perform any number of additional actions. This reduces the need to go back to Site Studio Designer or JDeveloper to make more advanced changes to the site. Dashboards As part of the updated records management functionality in both UCM and URM, users can now set a dashboard view on their home page to surface common functions in a single view. It has pre-built "portlets" users can choose from to display and organize they way they want. Behind the scenes, these dashboards are stored as Content Folios. So the dashboards themselves are content items that can be revisioned and shared between users. And new dashboard portlets can be easily added (like the User Profile one in the screenshots) by getting a copy of an existing one, modifying the display, and then checking it in as a new one to select from. URM Interface Enhancements URM includes several new UI and usability enhancements in 11g. There is a new view for physical records, a place to configure "favorite" items to quickly get to, and new placement of the records management menu. BI Publisher Reports Records management in UCM and URM now offer reports generated through embedded BI Publisher. Templates are controlled by rich text files checked directly into the repository, so they can be easily modified. Other Features A new Inbound Refinery conversion option is available that does native Microsoft Office HTML conversion. If your IBR is on Windows and you have the native applications loaded, the IBR can use them to produce HTML. A new GUI template editor for Dynamic Converter is available. It's written in Java so is available through all the supported browsers and platforms. The original ActiveX based editor is also still available. The Component Manager interface has changed to help provide an easier and more descriptive way to enable core components that are installed along with UCM. All of the supported components are immediately available to turn on and do not have to be installed separately as in previous versions. My Downloads is located in the My Content Server menu and provides for easy download of client installs including Desktop Integration Suite and Site Studio Designer. Well, hopefully that gives you a taste for some of the new things in 11g. We're all pretty excited here at Oracle about all the new changes and enhancements. Over the next few months I hope to highlight some of these features more in-depth, so keep your eye out for those posts.

Error "exit signal Bus error (7)" How to continue after making a backtrace?

- by Mikel

I have a Centos Server in 1and1 with Apache, Magento, MagentoBooster and Xcache installed. The server usually (1-8 times per day) prints this error "exit signal Bus error (7)" and sometimes this causes Apache not to respond. I have made a backtrace with GDB, but I don't know how to continue. gdb /usr/sbin/httpd core.XXXX --batch --quiet -ex "thread apply all bt full" backtrace.log The backtrace: [New Thread 15312] [Thread debugging using libthread_db enabled] Core was generated by `/usr/sbin/httpd'.

Silverlight 5 Hosting :: Features in Silverlight 5 and Release Date

- by mbridge

Silverlight 5 is finally announced in the Silverlight FireStarter Event on the 2nd December, 2010. This new version of Silverlight which was earlier labeled as 'Future of Microsoft Silverlight' has now come much closer to go live as the first Silverlight 5 Beta version is expected to be shipped during the early months of 2011. However for the full fledged and the final release of Silverlight 5, we have to wait many more months as the same is likely to be made available within the Q3 2011. As would have been usually expected, this latest edition would feature many new capabilities thereby extending the developer productivity to a whole new dimension of premium media experience and feature-rich business applications. It comes along with many new feature updates as well as the inclusion of new technologies to improve the standard of the Silverlight applications which are now fine-tuned to produce next generation business and media solutions that is capable to meet the requirements of the advanced web-based app development. The Silverlight 5 is all set to replace the previous fourth version which now includes more than forty new features while also dropping various deprecated elements that was prevalent earlier. It has brought around some major performance enhancements and also included better support for various other tools and technologies. Following are some of the changes that are registered to be available under the Silverlight 5 Beta edition which is scheduled to be launched during the Q1 2011. Silverlight 5 : Premium Media Experiences The media features of Silverlight 5 has seen some major enhancements with a lot of optimizations being made to deliver richer solutions. It's capability has now been extended to make things easier, faster and capable of performing the desired tasks in the most efficient manner. The Silverlight media solutions has already been a part of many companies in the recent days where various on-demand Silverlight services were featured but with the arrival of the next generation premium media solution of Silverlight 5, it is expected to register new heights of success and global user acclamation for using it with many esteemed web-based projects and media solutions. - The most happening element in the new Silverlight 5 will be its support for utilizing the GPU based hardware acceleration which is intended to lower down the CPU load to a significant extent and thereby allowing faster rendering of media contents without consuming much resources. This feature is believed to be particularly helpful for low configured machines to run full HD media content without any lagging caused due to processor load. It will hence be one great feature to revolutionize the new generation high quality media contents to be available within the web in a more efficient manner with its hardware decoded video playback capabilities. - With the inclusion of hardware video decoding to minimize the processor load, the Silverlight 5 also comes with another optimization enhancement to also reduce the power consumption level by making new methods to deal with the power-saver settings. With this optimization in effect, the computer would be automatically allowed to switch to sleep mode while no video playback is in progress and also to prevent any screensavers to popup and cause annoyances during any video playback. There would also be other power saver options which will be made available to best suit the users requirements and purpose. - The Silverlight trickplay feature is another great way to tweak any silverlight powered media content as is used for many video tutorial sites or for dealing with any sort of presentations. This feature enables the user to modify the playback speed to either slowdown or speedup during the playback durations based on the requirements without compromising on the quality of output. Normally such manipulations always makes the content's audio to go off-pitch, but the same will not be the case with TrickPlay and the audio would seamlessly progress with the video without skipping any of its part. - In addition to all of the above, the new Silverlight 5 will be featuring wireless control of all the media contents by making use of remote controllers. With the use of such remote devices, it will be easier to handle the various media playback controls thereby providing more freedom while experiencing the premium media services. Silverlight 5 : Business Application Development The application development standard has been extended with more possibilities by bringing forth new and useful technologies and also reviving the existing methods to work better than what it was used to. From the UI improvements to advanced technical aspects, the Silverlight 5 scores high on all grounds to produce great next generation business delivered applications by putting in more creativity and resourceful touch to all the apps being produced with it. - The WPF feature of Silverlight is made more effective by introducing new standards of Databinding which is intended to improve the productivity standards of the Silverlight application developer. It brings in a lot of convenience in debugging the databinding components or expressions and hence making things work in a flawless manner. Some additional features related to databinding includes that of Ancestor RelativeSource, Implicit DataTemplates and Model View ViewModel (MVVM) support with DataContextChanged event and many other new features relating it. - It now comes with a refined text and printing service which facilitates better clarity of the text rendering and also many positive changes which are being applied to the layout pattern. New supports has been added to include OpenType font, multi-column text, linked-text containers and character leading support to name a few among the available features.This also includes some important printing aspects like that of Postscript Vector Printing API which allows to program our printing tasks in a user defined way and Pivot functionality for visualization concerns of informations. - The Graphics support is the key improvements being incorporated which now enables to utilize three dimensional graphics pattern using GPU acceleration. It can manage to provide some really cool visualizations being curved to provide media contents within the business apps with also the support for full HD contents at 1080p quality. - Silverlight 5 includes the support for 64-bit operating systems and relevant browsers and is also optimized to provide better performance. It can support the background thread for the networking which can reduce the latency of the network to a considerable extent. The Out-of-Browser functionality adds the support for utilizing various libraries and also the Win32 API. It also comes with testing support with VS 2010 which is mostly an automated procedure and has also enabled increased security aspects of all the Silverlight 5 developed applications by using the improved version of group policy support.

Using C# 4.0’s DynamicObject as a Stored Procedure Wrapper

- by EltonStoneman

[Source: http://geekswithblogs.net/EltonStoneman] Overview Ignoring the fashion, I still make a lot of use of DALs – typically when inheriting a codebase with an established database schema which is full of tried and trusted stored procedures. In the DAL a collection of base classes have all the scaffolding, so the usual pattern is to create a wrapper class for each stored procedure, giving typesafe access to parameter values and output. DAL calls then looks like instantiate wrapper-populate parameters-execute call: using (var sp = new uspGetManagerEmployees()) { sp.ManagerID = 16; using (var reader = sp.Execute()) { //map entities from the output } } Or rolling it all into a fluent DAL call – which is nicer to read and implicitly disposes the resources: This is fine, the wrapper classes are very simple to handwrite or generate. But as the codebase grows, you end up with a proliferation of very small wrapper classes: The wrappers don't add much other than encapsulating the stored procedure call and giving you typesafety for the parameters. With the dynamic extension in .NET 4.0 you have the option to build a single wrapper class, and get rid of the one-to-one stored procedure to wrapper class mapping. In the dynamic version, the call looks like this: dynamic getUser = new DynamicSqlStoredProcedure("uspGetManagerEmployees", Database.AdventureWorks); getUser.ManagerID = 16; var employees = Fluently.Load<List<Employee>>() .With<EmployeeMap>() .From(getUser); The important difference is that the ManagerId property doesn't exist in the DynamicSqlStoredProcedure class. Declaring the getUser object with the dynamic keyword allows you to dynamically add properties, and the DynamicSqlStoredProcedure class intercepts when properties are added and builds them as stored procedure parameters. When getUser.ManagerId = 16 is executed, the base class adds a parameter call (using the convention that parameter name is the property name prefixed by "@"), specifying the correct SQL Server data type (mapping it from the type of the value the property is set to), and setting the parameter value. Code Sample This is worked through in a sample project on github – Dynamic Stored Procedure Sample – which also includes a static version of the wrapper for comparison. (I'll upload this to the MSDN Code Gallery once my account has been resurrected). Points worth noting are: DynamicSP.Data – database-independent DAL that has all the data plumbing code. DynamicSP.Data.SqlServer – SQL Server DAL, thin layer on top of the generic DAL which adds SQL Server specific classes. Includes the DynamicSqlStoredProcedure base class. DynamicSqlStoredProcedure.TrySetMember. Invoked when a dynamic member is added. Assumes the property is a parameter named after the SP parameter name and infers the SqlDbType from the framework type. Adds a parameter to the internal stored procedure wrapper and sets its value. uspGetManagerEmployees – the static version of the wrapper. uspGetManagerEmployeesTest – test fixture which shows usage of the static and dynamic stored procedure wrappers. The sample uses stored procedures from the AdventureWorks database in the SQL Server 2008 Sample Databases. Discussion For this scenario, the dynamic option is very favourable. Assuming your DAL is itself wrapped by a higher layer, the stored procedure wrapper classes have very little reuse. Even if you're codegening the classes and test fixtures, it's still additional effort for very little value. The main consideration with dynamic classes is that the compiler ignores all the members you use, and evaluation only happens at runtime. In this case where scope is strictly limited that's not an issue – but you're relying on automated tests rather than the compiler to find errors, but that should just encourage better test coverage. Also you can codegen the dynamic calls at a higher level. Performance may be a consideration, as there is a first-time-use overhead when the dynamic members of an object are bound. For a single run, the dynamic wrapper took 0.2 seconds longer than the static wrapper. The framework does a good job of caching the effort though, so for 1,000 calls the dynamc version still only takes 0.2 seconds longer than the static: You don't get IntelliSense on dynamic objects, even for the declared members of the base class, and if you've been using class names as keys for configuration settings, you'll lose that option if you move to dynamics. The approach may make code more difficult to read, as you can't navigate through dynamic members, but you do still get full debugging support. var employees = Fluently.Load<List<Employee>>() .With<EmployeeMap>() .From<uspGetManagerEmployees> ( i => i.ManagerID = 16, x => x.Execute() );

Request Limit Length Limits for IIS’s requestFiltering Module

- by Rick Strahl

Today I updated my CodePaste.net site to MVC 3 and pushed an update to the site. The update of MVC went pretty smooth as well as most of the update process to the live site. Short of missing a web.config change in the /views folder that caused blank pages on the server, the process was relatively painless. However, one issue that kicked my ass for about an hour – and not foe the first time – was a problem with my OpenId authentication using DotNetOpenAuth. I tested the site operation fairly extensively locally and everything worked no problem, but on the server the OpenId returns resulted in a 404 response from IIS for a nice friendly OpenId return URL like this: http://codepaste.net/Account/OpenIdLogon?dnoa.userSuppliedIdentifier=http%3A%2F%2Frstrahl.myopenid.com%2F&dnoa.return_to_sig_handle=%7B634239223364590000%7D%7BjbHzkg%3D%3D%7D&dnoa.return_to_sig=7%2BcGhp7UUkcV2B8W29ibIDnZuoGoqzyS%2F%2FbF%2FhhYscgWzjg%2BB%2Fj10ZpNdBkUCu86dkTL6f4OK2zY5qHhCnJ2Dw%3D%3D&openid.assoc_handle=%7BHMAC-SHA256%7D%7B4cca49b2%7D%7BMVGByQ%3D%3D%7D&openid.claimed_id=http%3A%2F%2Frstrahl.myopenid.com%2F&openid.identity=http%3A%2F%2Frstrahl.myopenid.com%2F&openid.mode=id_res&openid.ns=http%3A%2F%2Fspecs.openid.net%2Fauth%2F2.0&openid.ns.sreg=http%3A%2F%2Fopenid.net%2Fextensions%2Fsreg%2F1.1&openid.op_endpoint=http%3A%2F%2Fwww.myopenid.com%2Fserver&openid.response_nonce=2010-10-29T04%3A12%3A53Zn5F4r5&openid.return_to=http%3A%2F%2Fcodepaste.net%2FAccount%2FOpenIdLogon%3Fdnoa.userSuppliedIdentifier%3Dhttp%253A%252F%252Frstrahl.myopenid.com%252F%26dnoa.return_to_sig_handle%3D%257B634239223364590000%257D%257BjbHzkg%253D%253D%257D%26dnoa.return_to_sig%3D7%252BcGhp7UUkcV2B8W29ibIDnZuoGoqzyS%252F%252FbF%252FhhYscgWzjg%252BB%252Fj10ZpNdBkUCu86dkTL6f4OK2zY5qHhCnJ2Dw%253D%253D&openid.sig=h1GCSBTDAn1on98sLA6cti%2Bj1M6RffNerdVEI80mnYE%3D&openid.signed=assoc_handle%2Cclaimed_id%2Cidentity%2Cmode%2Cns%2Cns.sreg%2Cop_endpoint%2Cresponse_nonce%2Creturn_to%2Csigned%2Csreg.email%2Csreg.fullname&openid.sreg.email=rstrahl%40host.com&openid.sreg.fullname=Rick+Strahl A 404 of course isn’t terribly helpful – normally a 404 is a resource not found error, but the resource is definitely there. So how the heck do you figure out what’s wrong? If you’re just interested in the solution, here’s the short version: IIS by default allows only for a 1024 byte query string, which is obviously exceeded by the above. The setting is controlled by the RequestFiltering module in IIS 6 and later which can be configured in ApplicationHost.config (in \%windir\system32\inetsvr\config). To set the value configure the requestLimits key like so: <configuration> <security> <requestFiltering> <requestLimits maxQueryString="2048"> </requestLimits> </requestFiltering> </security> </configuration> This fixed me right up and made the requests work. How do you find out about problems like this? Ah yes the troubles of an administrator? Read on and I’ll take you through a quick review of how I tracked this down. Finding the Problem The issue with the error returned is that IIS returns a 404 Resource not found error and doesn’t provide much information about it. If you’re lucky enough to be able to run your site from the localhost IIS is actually very helpful and gives you the right information immediately in a nicely detailed error page. The bottom of the page actually describes exactly what needs to be fixed. One problem with this easy way to find an error: You HAVE TO run localhost. On my server which has about 10 domains running localhost doesn’t point at the particular site I had problems with so I didn’t get the luxury of this nice error page. Using Failed Request Tracing to retrieve Error Info The first place I go with IIS errors is to turn on Failed Request Tracing in IIS to get more error information. If you have access to the server to make a configuration change you can enable Failed Request Tracing like this: Find the Failed Request Tracing Rules in the IIS Service Manager. Select the option and then Edit Site Tracing to enable tracing. Then add a rule for * (all content) and specify status codes from 100-999 to capture all errors. if you know exactly what error you’re looking for it might help to specify it exactly to keep the number of errors down. Then run your request and let it fail. IIS will throw error log files into a folder like this C:\inetpub\logs\FailedReqLogFiles\W3SVC5 where the last 5 is the instance ID of the site. These files are XML but they include an XSL stylesheet that provides some decent formatting. In this case it pointed me straight at the offending module: Ok, it’s the RequestFilteringModule. Request Filtering is built into IIS 6-7 and configured in ApplicationHost.config. This module defines a few basic rules about what paths and extensions are allowed in requests and among other things how long a query string is allowed to be. Most of these settings are pretty sensible but the query string value can easily become a problem especially if you’re dealing with OpenId since these return URLs are quite extensive. Debugging failed requests is never fun, but IIS 6 and forward at least provides us the tools that can help us point in the right direction. The error message the FRT report isn’t as nice as the IIS error message but it at least points at the offending module which gave me the clue I needed to look at request restrictions in ApplicationHost.config. This would still be a stretch if you’re not intimately familiar, but I think with some Google searches it would be easy to track this down with a few tries… Hope this was useful to some of you. Useful to me to put this out as a reminder – I’ve run into this issue before myself and totally forgot. Next time I got it, right?© Rick Strahl, West Wind Technologies, 2005-2010Posted in ASP.NET Security

Top 10 Tips & Tricks for Oracle SQL Developer

- by thatjeffsmith

Being a short week due to the holiday, and with everyone enjoying their Summer vacations (apologies Southern Hemispherians), I reckoned it was a great time to do one of those lazy recap-Top 10-Reader’s Digest type posts. I’ve been sharing 1-3 tips or ‘tricks’ a week since I started blogging about SQL Developer, and I have more than enough content to write a book. But since I’m lazy, I’m just going to compile a list of my favorite ‘must know’ tips instead. I always have to leave out a few tips when I do my presentations, so now I can refer back to this list to make sure I’m not forgetting anything. So without further ado… 1. Configure Your Preferences Yes, there are a LOT of options. But you don’t need to worry about all of them just yet. I do recommend you take a quick look at these ones in particular. Whether you’re new to the tool or have been using it for 5 years, don’t overlook these settings! 2. Disable Extensions You Aren’t Using If you’re not using Data Miner, or if you’re not working on a Migration – disable those extensions! SQL Developer will run leaner & meaner, plus the user interface will be a bit more simplified making the tool easier to navigate as well. 3. SQL Recall via Keyboard Access your history via the keyboard! Cycle through your recent SQL statements just using these magic key strokes! Ctrl+Up or Ctrl+Down. 4. Format Your Query Output Directly to CSV, XML, HTML, etc Have the query results pre-formatted in the format of your choice! Too lazy to run the Export wizard for your query result sets? Just add the SQL Developer output hints to your statement and have the output auto-magically formatted to the style of your choice! 5. Drag & Drop Multiple Tables to the Worksheet SQL Developer will auto-join the related objects. You can then toggle over to the Query Builder to toggle off the columns you don’t want to query. I guarantee this tip will save you time if you’re joining 3 or more tables! 6. Drag & Drop Multiple Tables to a Relational Model A pretty picture is worth a few dozen DDL scripts? SQL Developer does data modeling! If you ctrl-drag a table to a model, it will take that table and any related tables and reverse engineer them to a relational model! You can then print it out or export it to HTML, PDF, etc. 7. View Your PL/SQL Execution Output Automatically Function returns a refcursor? Procedure had 3 out parameters? When you run these programs via the Procedure Editor, we automatically capture the output and place them into one or more data grids for you to browse. 8. Disable Automatic Code Insight and Use It On-Demand Code Editor – Completion Insight – Enable Completion Auto-Popup (Keyword being Auto) Some folks really don’t like it when their IDEs or word-processors try to do ‘too much’ for them. Thankfully SQL Developer allows you to either increase the delay before it attempts to auto-complete your text OR to disable the automatic bit. Instead, you can invoke it on-demand. 9. Interactive Debugging – Change Your Variable Values as You Step Through Your PLSQL Watches aren’t just for watching. You can actually interact with your programs and ‘see what happens’ when X = 256 instead of 1. 10. Ditch the Tree View for the Schema Browser There’s nothing wrong with the Connection tree for browsing your database objects. But some folks just can’t seem to get comfortable with it. So, we built them a Schema Browser that uses a drop down control instead for changing up your schema and object types. Already Know This Stuff, Want More? Just check out my SQL Developer resource page, it’s one of the main links on the top of this page. Or if you can’t find something, just drop me a note in the form of a comment on this page and I’ll do my best to find it or write it for you.

Silverlight 5 – What’s New? (Including Screenshots & Code Snippets)

- by mbcrump

Silverlight 5 is coming next year (2011) and this blog post will tell you what you need to know before the beta ships. First, let me address people saying that it is dead after PDC 2010. I believe that it’s best to see what the market is doing, not the vendor. Below is a list of companies that are developing Silverlight 4 applications shown during the Silverlight Firestarter. Some of the companies have shipped and some haven’t. It’s just great to see the actual company names that are working on Silverlight instead of “people are developing for Silverlight”. The next thing that I wanted to point out was that HTML5, WPF and Silverlight can co-exist. In case you missed Scott Gutherie’s keynote, they actually had a slide with all three stacked together. This shows Microsoft will be heavily investing in each technology. Even I, a Silverlight developer, am reading Pro HTML5. Microsoft said that according to the Silverlight Feature Voting site, 21k votes were entered. Microsoft has implemented about 70% of these votes in Silverlight 5. That is an amazing number, and I am crossing my fingers that Microsoft bundles Silverlight with Windows 8. Let’s get started… what’s new in Silverlight 5? I am going to show you some great application and actual code shown during the Firestarter event. Media Hardware Video Decode – Instead of using CPU to decode, we will offload it to GPU. This will allow netbooks, etc to play videos. Trickplay – Variable Speed Playback – Pitch Correction (If you speed up someone talking they won’t sound like a chipmunk). Power Management – Less battery when playing video. Screensavers will no longer kick in if watching a video. If you pause a video then screensaver will kick in. Remote Control Support – This will allow users to control playback functions like Pause, Rewind and Fastforward. IIS Media Services 4 has shipped and now supports Azure. Data Binding Layout Transitions – Just with a few lines of XAML you can create a really rich experience that is not using Storyboards or animations. RelativeSource FindAncestor – Ancestor RelativeSource bindings make it much easier for a DataTemplate to bind to a property on a container control. Custom Markup Extensions – Markup extensions allow code to be run at XAML parse time for both properties and event handlers. This is great for MVVM support. Changing Styles during Runtime By Binding in Style Setters – Changing Styles at runtime used to be a real pain in Silverlight 4, now it’s much easier. Binding in style setters allows bindings to reference other properties. XAML Debugging – Below you can see that we set a breakpoint in XAML. This shows us exactly what is going on with our binding. WCF & RIA Services WS-Trust Support – Taken from Wikipedia: WS-Trust is a WS-* specification and OASIS standard that provides extensions to WS-Security, specifically dealing with the issuing, renewing, and validating of security tokens, as well as with ways to establish, assess the presence of, and broker trust relationships between participants in a secure message exchange. You can reduce network latency by using a background thread for networking. Supports Azure now. Text and Printing Improved text clarity that enables better text rendering. Multi-column text flow, Character tracking and leading support, and full OpenType font support. Includes a new Postscript Vector Printing API that provides control over what you print . Pivot functionality baked into Silverlight 5 SDK. Graphics Immediate mode graphics support that will enable you to use the GPU and 3D graphics supports. Take a look at what was shown in the demos below. 1) 3D view of the Earth – not really a real-world application though. A doctor’s portal. This demo really stood out for me as it shows what we can do with the 3D / GPU support. Out of Browser OOB applications can now create and manage childwindows as shown in the screenshot below. Trusted OOB applications can use P/Invoke to call Win32 APIs and unmanaged libraries. Enterprise Group Policy Support allow enterprises to lock down or up the sandbox capabilities of Silverlight 5 applications. In this demo, he tore the “notes” off of the application and it appeared in a new window. See the black arrow below. In this demo, he connected a USB Device which fired off a local Win32 application that provided the data off the USB stick to Silverlight. Another demo of a Silverlight 5 application exporting data right into Excel running inside of browser. Testing They demoed Coded UI, which is available now in the Visual Studio Feature Pack 2. This will allow you to create automated testing without writing any code manually. Performance: Microsoft has worked to improve the Silverlight startup time. Silverlight 5 provides 64-bit browser support. Silverlight 5 also provides IE9 Hardware acceleration. I am looking forward to Silverlight 5 and I hope you are too. Thanks for reading and I hope you visit again soon. Subscribe to my feed CodeProject

Above the Fold: Silverlight: "Asynchronous Callbacks with Rx" Jesse Liberty WP7: "Phoney Windows Phone 7 Project Now Available!" Shawn Wildermuth MVVM: "Validating our ViewModel" Mark Monster Shoutouts: Shawn Wildermuth has a video up of his FadingMessage class to show it off: Introducing Phoney's FadingMessage Class From SilverlightCream.com: Validating our ViewModel Mark Monster discusses Validation in his latest post... using INotifyDataErrorInfo and his own implementation of a ViewModel base that supports it and INPC. Getting ready for Microsoft Silverlight Exam 70-506 (Part 7) Gill Cleeren hits part 7 of his series at SilverlightShow on a great walk through Silverlight and getting ready for the exam. This is the final part and concentrates on deploying apps. Windows Phone 7–Creating Custom Keyboard Pencho Popadiyn has a post at SilverlightShow discussing problems with WP7 keyboards in his native Bulgaria, and his solution to the problem... create his own. 360 Degrees Feedback by Kevin Dockx Kevin Dockx produced a white paper for his company about an employee review solution they did in Silverlight. The white paper is available, and SilverlightShow interviewd Kevin to answer questions about the app. Extended Windows Phone 7 page for handling rotation, focused element updates and back key press Looks like Joost van Schaik has a few posts I've missed... and I'm not going to get to them all today! ... this one is about the base class he uses for WP7 apps... a bunch of utilities he uses... definitely worth a look (and a take). Asynchronous Callbacks with Rx Jesse Liberty has his 8th post in the Rx series up and this one's on Asynchronous Callbacks... if you haven't seen this before, you should definitely look into it... cool stuff, Jesse!

Microsoft Sql Server driver for Nodejs - Part 2

- by chanderdhall

Nodejs, Sql server and Json response with Rest This post is part 2 of Microsoft Sql Server driver for Node js.In this post we will look at the JSON responses from the Microsoft Sql Server driver for Node js. Pre-requisites: If you have read the Part 1 of the series, you should be good. We will be using a framework for Rest within Nodejs - Restify, but that would need no prior learning. Restify: Restify is a simple node module for building RESTful services. It is slimmer than Express. Express is a complete module that has all what you need to create a full-blown browser app. However, Restify does not have additional overhead of templating, rendering etc that would be needed if your app has views. So, as the name suggests it's an awesome framework for building RESTful services and is very light-weight. Set up - You can continue with the same directory or project structure we had in the previous post, or can start a new one. Install restify using npm and you are good to go. npm install restify Go to Server.js and include Restify in your solution. Then create the server object using restify.CreateServer() - SLICK - ha? var restify = require('restify'); var server = restify.createServer(); server.listen(8080, function () { console.log('%s listening at %s', server.name, server.url); }); Then make sure you provide a port for the Server to listen at. The call back function is optional but helps you for debugging purposes. Once you are done, save the file and then go to the command prompt and hit 'node server.js' and you should see the following: To test the server, go to your browser and type the address 'http://localhost:8080/' and oops you will see an error. Why is that? - Well because we haven't defined any routes. Let's go ahead and create a route. To begin with I'd like to return whatever is typed in the url after my name and the following code should do it. server.get('/ChanderDhall/:status', function respond(req, res, next) { res.end("hello " + req.params.name + "") }); You can also avoid writing call backs inline. Something like this. function respond(req, res, next) { res.end("Chander Dhall " + req.params.name + ""); } server.get('/hello/:name', respond); Now if you go ahead and type http://localhost:8080/ChanderDhall/LovesNode you will get the response 'Chander Dhall loves node'. NOTE: Make sure your url has the right case as it's case-sensitive. You could have also typed it in as 'server.get('/chanderdhall/:name', respond);' Stored procedure: We've talked a lot about Restify now, but keep in mind the post is about being able to use Sql server with Node and return JSON. To see this in action, let's go ahead and create another route to a list of Employees from a stored procedure. server.get('/Employees', Employees); The following code will return a JSON response. function Employees(req, res, next) { res.header("Content-Type: application/json"); //Need to specify the Content-Type which is //JSON in our case. sql.open(conn_str, function (err, conn) { if (err) { //Logs an error console.log("Error opening the database connection!"); return; } console.log("before query!"); conn.queryRaw("exec sp_GetEmployees", function (err, results) { if (err) { //Connection is open but an error occurs whileWhat else can be done? May be create a formatter or may be even come up with a hypermedia type but that may upset some pragmatists. Well, that's going to be a totally different discussion and is really not part of this series. Summary: We've discussed how to execute a stored procedure using Microsoft Sql Server driver for Node. Also, we have discussed how to format and send out a clean JSON to the app calling this API.

After some debugging, I was able to narrow it down to a few things. For some reason the sshd daemon is running as root:www-data (apache user) instead of root. My ftp connection works but ssh over terminal fails. I have no idea whether it is getting caused due to suPHP or not (because that is the only place where user permission's etc. change). I really need to narrow it down and fix it asap. Thanks a lot!

F# for the C# Programmer

- by mbcrump

Are you a C# Programmer and can’t make it past a day without seeing or hearing someone mention F#? Today, I’m going to walk you through your first F# application and give you a brief introduction to the language. Sit back this will only take about 20 minutes. Introduction Microsoft's F# programming language is a functional language for the .NET framework that was originally developed at Microsoft Research Cambridge by Don Syme. In October 2007, the senior vice president of the developer division at Microsoft announced that F# was being officially productized to become a fully supported .NET language and professional developers were hired to create a team of around ten people to build the product version. In September 2008, Microsoft released the first Community Technology Preview (CTP), an official beta release, of the F# distribution . In December 2008, Microsoft announced that the success of this CTP had encouraged them to escalate F# and it is now will now be shipped as one of the core languages in Visual Studio 2010 , alongside C++, C# 4.0 and VB. The F# programming language incorporates many state-of-the-art features from programming language research and ossifies them in an industrial strength implementation that promises to revolutionize interactive, parallel and concurrent programming. Advantages of F# F# is the world's first language to combine all of the following features: Type inference: types are inferred by the compiler and generic definitions are created automatically. Algebraic data types: a succinct way to represent trees. Pattern matching: a comprehensible and efficient way to dissect data structures. Active patterns: pattern matching over foreign data structures. Interactive sessions: as easy to use as Python and Mathematica. High performance JIT compilation to native code: as fast as C#. Rich data structures: lists and arrays built into the language with syntactic support. Functional programming: first-class functions and tail calls. Expressive static type system: finds bugs during compilation and provides machine-verified documentation. Sequence expressions: interrogate huge data sets efficiently. Asynchronous workflows: syntactic support for monadic style concurrent programming with cancellations. Industrial-strength IDE support: multithreaded debugging, and graphical throwback of inferred types and documentation. Commerce friendly design and a viable commercial market. Lets try a short program in C# then F# to understand the differences. Using C#: Create a variable and output the value to the console window: Sample Program. using System; namespace ConsoleApplication9 { class Program { static void Main(string[] args) { var a = 2; Console.WriteLine(a); Console.ReadLine(); } } } A breeze right? 14 Lines of code. We could have condensed it a bit by removing the “using” statment and tossing the namespace. But this is the typical C# program. Using F#: Create a variable and output the value to the console window: To start, open Visual Studio 2010 or Visual Studio 2008. Note: If using VS2008, then please download the SDK first before getting started. If you are using VS2010 then you are already setup and ready to go. So, click File-> New Project –> Other Languages –> Visual F# –> Windows –> F# Application. You will get the screen below. Go ahead and enter a name and click OK. Now, you will notice that the Solution Explorer contains the following: Double click the Program.fs and enter the following information. Hit F5 and it should run successfully. Sample Program. open System let a = 2 Console.WriteLine a As Shown below: Hmm, what? F# did the same thing in 3 lines of code. Show me the interactive evaluation that I keep hearing about. The F# development environment for Visual Studio 2010 provides two different modes of execution for F# code: Batch compilation to a .NET executable or DLL. (This was accomplished above). Interactive evaluation. (Demo is below) The interactive session provides a > prompt, requires a double semicolon ;; identifier at the end of a code snippet to force evaluation, and returns the names (if any) and types of resulting definitions and values. To access the F# prompt, in VS2010 Goto View –> Other Window then F# Interactive. Once you have the interactive window type in the following expression: 2+3;; as shown in the screenshot below: I hope this guide helps you get started with the language, please check out the following books for further information. F# Books for further reading Foundations of F# Author: Robert Pickering An introduction to functional programming with F#. Including many samples, this book walks through the features of the F# language and libraries, and covers many of the .NET Framework features which can be leveraged with F#. Functional Programming for the Real World: With Examples in F# and C# Authors: Tomas Petricek and Jon Skeet An introduction to functional programming for existing C# developers written by Tomas Petricek and Jon Skeet. This book explains the core principles using both C# and F#, shows how to use functional ideas when designing .NET applications and presents practical examples such as design of domain specific language, development of multi-core applications and programming of reactive applications.

Dual Boot Oracle Solaris 11/11 and Linux (Ubuntu 11.10/grub2)

- by HartmutStreppel

After having worked with Open Solaris on my laptop first, then with an upgrade to Oracle Solaris 11 Express, I finally did a fresh install of Oracle Solaris 11/11, when it became available. I am not a big fan of upgrades as I know that I am not the perfect administrator and my system gets spoiled with unclean configurations, outdated packages and wrong settings that cannot be reversed. So I prefer to start from scratch. Especially with Oracle Solaris 11 I wanted to have a system just like a customer would have it in production. The installation was smooth - more or less, if I had only read the documentation a bit better in advance. For a number of reasons I prefer a dual boot system. The most important one is, that especially with mobile devices you often run into network problems. And you have a hard time figuring out where the problem is: in your laptop hardware, in the OS you are running, or really within the network. If you have an alternate OS to boot, you can exclude the OS and your hardware. This makes you feel better. The second OS should be a Linux variant - and for some not so obvious reason I decided to go with the latest Ubuntu release (11.10). It replaced a very old Open Suse installation that had not been booted for a while. I knew that it was probably best to install Ubuntu first and then Oracle Solaris 11, as this would put the right boot information for Oracle Solaris into the MBR and onto the root partition. But then, how to enable dual boot with the 2 OSes. Searching the web one mainly finds information about dual boot of: Linux and Linux Linux and Windows I do not want to explain which wrong configurations I worked through, but I prefer to explain the final setup, which is extremely simple, and I am wondering why this is not covered as the easiest solution for most dual boot setups. I use chainloader from and to both OS'es, with the only disadvantage that I have to confirm two grub menus each time I want to boot the "other" OS. Still there were some hurdles to jump over: Ubuntu did not like getting its boot blocks being placed on the partition instead of the disk; I must admit that I do not fully understand why. But using the --force option you could get that done Ubuntu needs an active partition; that was easy to achieve grub2 uses a different numbering scheme for the partitions. That is in the docs, if you read them. BTW: The usual disclaimer is valid. There is no guarantee that what I describe works or works well. Please back up your data carefully before trying any of this. So, Oracle Solaris 11 is installed on the first partition and Ubuntu on the third. With Ubtuntu things initially were a bit more complicated, as I did not know how to boot it. And the live CD did not offer the capability to boot the on-disk image (at least I did not find it). So I booted the live CD, mounted the Ubuntu installation at /mnt and wrote the boot blocks into the partition. This is something that does not seem to be recommended, at least grub-install refrained from doing what I intended. After a bit more research I was bold enough to use the --force option and wrote the boot blocks to /dev/sda3 using grub-install --boot-directory=/mnt/boot --force --no-floppy /dev/sda3 So, I now had a system with the Solaris boot loader in the MBR, Solaris specific boot blocks on the Solaris root partition and Ubuntu specific boot blocks in the Ubuntu partition. I just had to chain them together and I was done. Oracle Solaris 11: I have added the following lines to /rpool/boot/grub/menu.lst (be aware of the /rpool!!!!) title Ubuntu 11.10root (hd0,2)makeactivechainloader +1boot The Ubuntu root file system sits on the third partition (/dev/sda3). Ubuntu: I have added the following lines to /etc/grub.d/40_custom: menuentry "Solaris 11/11" { set root=(hd0,1) chainloader +1} Two things need to be mentioned: a) grub2 starts numbering partitions with 1; so my /dev/sda1 is partition 1. b) Oracle Solaris boots without the partition being made active (btw: the command to make a partition active with grub2 is "parttool (hd0,1) boot+", which currently does not work for me). As debugging grub is a bit complicated, I used the grub CLI to perform some tests and also used a tool, that I found on sourceforge.net that was able to prepare a list of all boot loaders on all partitions. This told me that the basic setup was correct. Unfortunately I lost it in the live CD environment. I hope this is helpful for some of the readers.Hartmut

Do Not Optimize Without Measuring

- by Alois Kraus

Recently I had to do some performance work which included reading a lot of code. It is fascinating with what ideas people come up to solve a problem. Especially when there is no problem. When you look at other peoples code you will not be able to tell if it is well performing or not by reading it. You need to execute it with some sort of tracing or even better under a profiler. The first rule of the performance club is not to think and then to optimize but to measure, think and then optimize. The second rule is to do this do this in a loop to prevent slipping in bad things for too long into your code base. If you skip for some reason the measure step and optimize directly it is like changing the wave function in quantum mechanics. This has no observable effect in our world since it does represent only a probability distribution of all possible values. In quantum mechanics you need to let the wave function collapse to a single value. A collapsed wave function has therefore not many but one distinct value. This is what we physicists call a measurement. If you optimize your application without measuring it you are just changing the probability distribution of your potential performance values. Which performance your application actually has is still unknown. You only know that it will be within a specific range with a certain probability. As usual there are unlikely values within your distribution like a startup time of 20 minutes which should only happen once in 100 000 years. 100 000 years are a very short time when the first customer tries your heavily distributed networking application to run over a slow WIFI network… What is the point of this? Every programmer/architect has a mental performance model in his head. A model has always a set of explicit preconditions and a lot more implicit assumptions baked into it. When the model is good it will help you to think of good designs but it can also be the source of problems. In real world systems not all assumptions of your performance model (implicit or explicit) hold true any longer. The only way to connect your performance model and the real world is to measure it. In the WIFI example the model did assume a low latency high bandwidth LAN connection. If this assumption becomes wrong the system did have a drastic change in startup time. Lets look at a example. Lets assume we want to cache some expensive UI resource like fonts objects. For this undertaking we do create a Cache class with the UI themes we want to support. Since Fonts are expensive objects we do create it on demand the first time the theme is requested. A simple example of a Theme cache might look like this: using System; using System.Collections.Generic; using System.Drawing; struct Theme { public Color Color; public Font Font; } static class ThemeCache { static Dictionary<string, Theme> _Cache = new Dictionary<string, Theme> { {"Default", new Theme { Color = Color.AliceBlue }}, {"Theme12", new Theme { Color = Color.Aqua }}, }; public static Theme Get(string theme) { Theme cached = _Cache[theme]; if (cached.Font == null) { Console.WriteLine("Creating new font"); cached.Font = new Font("Arial", 8); } return cached; } } class Program { static void Main(string[] args) { Theme item = ThemeCache.Get("Theme12"); item = ThemeCache.Get("Theme12"); } } This cache does create font objects only once since on first retrieve of the Theme object the font is added to the Theme object. When we let the application run it should print “Creating new font” only once. Right? Wrong! The vigilant readers have spotted the issue already. The creator of this cache class wanted to get maximum performance. So he decided that the Theme object should be a value type (struct) to not put too much pressure on the garbage collector. The code Theme cached = _Cache[theme]; if (cached.Font == null) { Console.WriteLine("Creating new font"); cached.Font = new Font("Arial", 8); } does work with a copy of the value stored in the dictionary. This means we do mutate a copy of the Theme object and return it to our caller. But the original Theme object in the dictionary will have always null for the Font field! The solution is to change the declaration of struct Theme to class Theme or to update the theme object in the dictionary. Our cache as it is currently is actually a non caching cache. The funny thing was that I found out with a profiler by looking at which objects where finalized. I found way too many font objects to be finalized. After a bit debugging I found the allocation source for Font objects was this cache. Since this cache was there for years it means that the cache was never needed since I found no perf issue due to the creation of font objects. the cache was never profiled if it did bring any performance gain. to make the cache beneficial it needs to be accessed much more often. That was the story of the non caching cache. Next time I will write something something about measuring.

- by Laila

Win a .NET Reflector Pro license, a box of Red Gate goodies, and a t-shirt printed with your design! Red Gate likes t-shirts. Each of our teams has one. In fact, each individual person has one, numbered according to when they joined the company: Red Gate's 1st, 2nd, and so on right up to Red Gate's 170th, with the slogan "More than just a number". Those t-shirts are important, chiefly because they remind the people wearing them that they are important. But that isn't enough. What really makes us great are the people who choose to use our tools. So we'd like to extend our tradition of t-shirts to include you and put the design of our next shirt entirely in your hands. We'd like you to come up with a witty slogan or create an inventive or simply beautiful t-shirt design for .NET Reflector Pro, our add-in for Visual Studio, which allows you to step into decompiled assemblies whilst debugging in Visual Studio. When you're done, post your masterpiece to Twitter with the hash tag #reflectortees, and @redgate will take a look! We'll pick the best design, and the winner will get a licensed copy of .NET Reflector Pro and a box of Red Gate goodies - not to mention a copy of their t-shirt. The winning design will go into production and be worn and given out at tradeshows, conferences, and user group events across the world, proudly bearing the name of their designer. We'll also pick three runners-up who will receive licenses for .NET Reflector Pro. Red Gate goodie box Interested? If you're up for the challenge, then we've got some resources to get you started. Inside the .zip file you'll find high-quality versions of the following: T-shirt templates: don't forget to design the front and the back! Different versions of the .NET Reflector Pro logo and Red Gate logo. Colour sheets to give you an easy reference to the Red Gate colours, including hex and RGB values. You can create and send us as many designs as you like, and each of them will be considered for the prize. To submit your designs, simply tweet including the competition hash tag, #reflectortees, and a link to somewhere we can see your design: either an image hosting site such as Twitpic, Flickr or Picasa, or a personal blog. You will need to create a Twitter account (which is free), if you don't already have one. You only have three limits: The background colour of the t-shirt should be one of our brand colours (red, light/dark grey or black), though you're welcome to use other colours in the rest of the design. You need to make use of either the .NET Reflector Pro logo OR the Red Gate logo (please keep them as they are) If you include any text or slogan, stick with just one or two colors for it. Apart from that, go wild. Go and do whatever it is you do when you get creative: whether you walk barefoot on the grass with a pencil and paper, sit cross-legged on a pile of cushions with a laptop, or simply close your eyes and float through a mist of ideas, now is your chance.

Understanding each other in web development

- by Pete Hotchkin

During my career I have been lucky enough to work in several different roles within web development with many extremely talented people, from incredible designers who were passionate about the placement of every pixel right through to server administrators and DBAs who were always measuring the improvements they were making to their queries in the smallest possible unit. The problem I always faced was that more often than not I was stuck in the middle trying to mediate between these different functions and enable each side to understand the other’s point of view. The main areas of contention that there have always been between these functional groups in my experience have been at 2 key points: during the build phase and then when there is a problem post-build. During both of these times it is often easier for someone to pass the buck onto someone else than spend the time to understand the other person’s perspective. Below is a quick look at two upcoming tools that will not only speed up the build phase for each function, but also help when it comes to the issues faced once a site has been pushed live. In my experience a web project goes through several phases of development. The first of these is design, generally handled as Photoshop files which are then passed onto a front-end developer. This is the first point at which heated discussions can arise. One problem I’ve seen several times is that the designer doesn’t fully understand the platform constraints that need to be considered, and as a result has designed something that does not translate very well or is simply not possible. Working at Red Gate, I am lucky enough to be able to meet some amazing people and this happened just the other day when I was introduced to Neil Kinnish and Pete Nelson, the creators of what I believe could be a great asset in this designer-developer relationship, Mixture. Mixture allows the front end developer to quickly prototype a web page with built-in frameworks such as bootstrap. It’s not an IDE however, it just sits there in the background and monitors the project files in the background so every time you save a file from your favorite IDE, it will compile things like LESS, compact your JavaScript and the automatically refresh your test browser so you can see the changes instantly. I think one of the best parts of this however is a single button that pushes the changed files up to the web so the designer can instantly see how far the developer has got and the problem that he is facing at that time without the need to spend time setting up a remote server. I can see this being a real asset to remote teams where there needs to be a compromise between the designer and the front-end developer, or just to allow the designer to see how the build is progressing and suggest small alterations. Once the design has been built into the front end the designer’s job is generally done and there are no other points of contention between the designer and the other functions involved in building these web projects. As the project moves into the stage of integrating it into the back end and deploying it to the production server other functions start to be pulled in and other issues arise such as the back-end developer understanding the frameworks that they are using such as the routes that are in place in an MVC application or the number of database calls that the ORM layer is actually making. There are many tools out there that can actually help with these problems such as mini profiler that gives you a quick snapshot of what is going on directly in the browser. For a slightly more in-depth look at what is happening and to gain a deeper understanding of an application you may be working on though, you may want to consider Glimpse. Created by Nik and Anthony, it is an application that sits at the bottom of your browser (installed via NuGet) which can show you information about how your application is pieced together and how the information on screen is being delivered as it happens. With a wealth of community-built plugins such as one for nHibernate and linq2SQL (full list of plugins on NuGet). It can be customized directly to your own setup to truly delve into the code to see what is happening, and can help to reduce the number of confusing moments about whether it is your code that is going wrong or whether there is something more sinister happening directly on the server. All the tools that I have mentioned in this post help to do one thing above all, and that is to ease the barrier of understanding between the different functions that are involved in building and maintaining a web application. In my experience it is very easy to say “Well, that’s not my problem”, simply because the two functions involved don’t truly understand the other’s point of view. Software should not only be seen as a way to streamline our own working process or as a debugging tool but also a communication aid to improve the entire lifecycle of a web project. Glimpse is actually the project that I am the designer on and I would love to get your feedback if you do decide to try it out or if you would like to share your own experiences of working on web projects please fill in your details at https://www.surveymk.com/s/joinGlimpse or add a comment below and I will get in touch with you.

Windows Workflow Foundation (WF) and things I wish were more intuitive

- by pjohnson

I've started using Windows Workflow Foundation, and so far ran into a few things that aren't incredibly obvious. Microsoft did a good job of providing a ton of samples, which is handy because you need them to get anywhere with WF. The docs are thin, so I've been bouncing between samples and downloadable labs to figure out how to implement various activities in a workflow. Code separation or not? You can create a workflow and activity in Visual Studio with or without code separation, i.e. just a .cs "Component" style object with a Designer.cs file, or a .xoml XML markup file with code behind (beside?) it. Absence any obvious advantage to one or the other, I used code separation for workflows and any complex custom activities, and without code separation for custom activities that just inherit from the Activity class and thus don't have anything special in the designer. So far, so good. Workflow Activity Library project type - What's the point of this separate project type? So far I don't see much advantage to keeping your custom activities in a separate project. I prefer to have as few projects as needed (and no fewer). The Designer's Toolbox window seems to find your custom activities just fine no matter where they are, and the debugging experience doesn't seem to be any different. Designer Properties - This is about the designer, and not specific to WF, but nevertheless something that's hindered me a lot more in WF than in Windows Forms or elsewhere. The Properties window does a good job of showing you property values when you hover the mouse over the values. But they don't do the same to find out what a control's type is. So maybe if I named all my activities "x1" and "x2" instead of helpful self-documenting names like "listenForStatusUpdate", then I could easily see enough of the type to determine what it is, but any names longer than those and all I get of the type is "System.Workflow.Act" or "System.Workflow.Compone". Even hitting the dropdown doesn't expand any wider, like the debugger quick watch "smart tag" popups do when you scroll through members. The only way I've found around this in VS 2008 is to widen the Properties dialog, losing precious designer real estate, then shrink it back down when you're done to see what you were doing. Really? WF Designer - This is about the designer, and I believe is specific to WF. I should be able to edit the XML in a .xoml file, or drag and drop using the designer. With WPF (at least in VS 2010 Ultimate), these are side by side, and changes to one instantly update the other. With WF, I have to right-click on the .xoml file, choose Open With, and pick XML Editor to edit the text. It looks like this is one way where WF didn't get the same attention WPF got during .NET Fx 3.0 development. Service - In the WF world, this is simply a class that talks to the workflow about things outside the workflow, not to be confused with how the term "service" is used in every other context I've seen in the Windows and .NET world, i.e. an executable that waits for events or requests from a client and services them (Windows service, web service, WCF service, etc.). ListenActivity - Such a great concept, yet so unintuitive. It seems you need at least two branches (EventDrivenActivity instances), one for your positive condition and one for a timeout. The positive condition has a HandleExternalEventActivity, and the timeout has a DelayActivity followed by however you want to handle the delay, e.g. a ThrowActivity. The timeout is simple enough; wiring up the HandleExternalEventActivity is where things get fun. You need to create a service (see above), and an interface for that service (this seems more complex than should be necessary--why not have activities just wire to a service directly?). And you need to create a custom EventArgs class that inherits from ExternalDataEventArgs--you can't create an ExternalDataEventArgs event handler directly, even if you don't need to add any more information to the event args, despite ExternalDataEventArgs not being marked as an abstract class, nor a compiler error nor warning nor any other indication that you're doing something wrong, until you run it and find that it always times out and get to check every place mentioned here to see why. Your interface and service need an event that consumes your custom EventArgs class, and a method to fire that event. You need to call that method from somewhere. Then you get to hope that you did everything just right, or that you can step through code in the debugger before your Delay timeout expires. Yes, it's as much fun as it sounds. TransactionScopeActivity - I had the bright idea of putting one in as a placeholder, then filling in the database updates later. That caused this error: The workflow hosting environment does not have a persistence service as required by an operation on the workflow instance "[GUID]". ...which is about as helpful as "Object reference not set to an instance of an object" and even more fun to debug. Google led me to this Microsoft Forums hit, and from there I figured out it didn't like that the activity had no children. Again, a Validator on TransactionScopeActivity would have pointed this out to me at design time, rather than handing me a nearly useless error at runtime. Easily enough, I disabled the activity and that fixed it. I still see huge potential in my work where WF could make things easier and more flexible, but there are some seriously rough edges at the moment. Maybe I'm just spoiled by how much easier and more intuitive development elsewhere in the .NET Framework is.

WebCenter Content (WCC) Trace Sections

- by Kevin Smith

Kyle has a good post on how to modify the size and number of WebCenter Content (WCC) trace files. His post reminded me I have been meaning to write a post on WCC trace sections for a while. searchcache - Tells you if you query was found in the WCC search cache. searchquery - Shows the processing of the query as it is converted form what the user submitted to the end query that will be sent to the database. Shows conversion from the universal query syntax to the syntax specific to the search solution WCC is configured to use. services (verbose) - Lists the filters that are called for each service. This will let you know what filters are available for each service and will also tell you what filters are used by WCC add-on components and any custom components you have installed. The How To Component Sample has a list of filters, but it has not been updated since 7.5, so it is a little outdated now. With each new release WCC adds more filters. If you have a filter that has no code attached to it you will see output like this: services/6 09.25 06:40:26.270 IdcServer-423 Called filter event computeDocName with no filter plugins registered When a WCC add-on or custom component uses a filter you will see trace output like this: services/6 09.25 06:40:26.275 IdcServer-423 Calling filter event postValidateCheckinData on class collections.CollectionValidateCheckinData with parameter postValidateCheckinDataservices/6 09.25 06:40:26.275 IdcServer-423 Calling filter event postValidateCheckinData on class collections.CollectionFilters with parameter postValidateCheckinData As you can see from this sample output it is possible to have multiple code points using the same filter. systemdatabase - Dumps the database call AFTER it executes. This can be somewhat troublesome if you are trying to track down some weird database problems. We had a problem where WCC was getting into a deadlock situation. We turned on the systemdatabase trace section and thought we had the problem database call, but it turned out since it printed out the database call after it was executed we were looking at the database call BEFORE the one causing the deadlock. We ended up having to turn on tracing at the database level to see the database call WCC was making that was causing the deadlock. socketrequests (verbose) - dumps the actual messages received and sent over the socket connection by WCC for a service. If you have gzip enabled you will see junk on the response coming back from WCC. For debugging disable the gzip of the WCC response.Here is an example of the dump of the request for a GET_SEARCH_RESULTS service call. socketrequests/6 09.25 06:46:02.501 IdcServer-6 request: REMOTE_USER=sysadmin.USER-AGENT=Java;.Stel socketrequests/6 09.25 06:46:02.501 IdcServer-6 request: lent.CIS.11g.CONTENT_TYPE=text/html.HEADER socketrequests/6 09.25 06:46:02.501 IdcServer-6 request: _ENCODING=UTF-8.REQUEST_METHOD=POST.CONTEN socketrequests/6 09.25 06:46:02.501 IdcServer-6 request: T_LENGTH=270.HTTP_HOST=CIS.$$$$.NoHttpHead socketrequests/6 09.25 06:46:02.501 IdcServer-6 request: ers=0.IsJava=1.IdcService=GET_SEARCH_RESUL socketrequests/6 09.25 06:46:02.501 IdcServer-6 request: [email protected] socketrequests/6 09.25 06:46:02.501 IdcServer-6 request: calData.SortField=dDocName.ClientEncoding= socketrequests/6 09.25 06:46:02.501 IdcServer-6 request: UTF-8.IdcService=GET_SEARCH_RESULTS.UserTi socketrequests/6 09.25 06:46:02.501 IdcServer-6 request: meZone=UTC.UserDateFormat=iso8601.SortDesc socketrequests/6 09.25 06:46:02.501 IdcServer-6 request: =ASC.QueryText=dDocType..matches..`Documen socketrequests/6 09.25 06:46:02.501 IdcServer-6 request: t`.@end. userstorage, jps - Provides trace details for user authentication and authorization. Includes information on the determination of what roles and accounts a user has access to. In 11g a new trace section, jps, was added with the addition of the JpsUserProvider to communicate with WebLogic Server. The WCC developers decide when to use the verbose option for their trace output, so sometime you need to try verbose to see what different information you get. One of the things I would always have liked to see if the ability to turn on verbose output selectively for individual trace sections. When you turn on verbose output you get it for all trace sections you have enabled. This can quickly fill up your trace files with a lot of information if you have the socket trace section turned on.

A little primer on using TFS with a small team

- by johndoucette

The scenario; A small team of 3 developers mostly in maintenance mode with traditional ASP.net, classic ASP, .Net integration services and utilities with the company’s third party packages, and a bunch of java-based Coldfusion web applications all under Visual Source Safe (VSS). They are about to embark on a huge SharePoint 2010 new construction project and wanted to use subversion instead VSS. TFS was a foreign word and smelled of “high cost” and of an “over complicated process”. Since they had no preconditions about the old TFS versions (‘05 & ‘08), it was fun explaining how simple it was to install a TFS server and get the ball rolling, with or without all the heavy stuff one sometimes associates with such a huge and powerful application management lifecycle product. So, how does a small team begin using TFS? 1. Start by using source control and migrate current VSS source trees into TFS. You can take the latest version or migrate the entire version history. It’s up to you on whether you want a clean start or need quick access to all the version notes and history of the bits. 2. Since most shops are mainly in maintenance mode with existing applications, begin using bug workitems for everything. When you receive an issue/bug from your current tracking system, manually enter the workitem in TFS right through Visual Studio. You can automate the integration to the current tracking system later or replace it entirely. Believe me, this thing is powerful and can handle even the largest of help desks. 3. With new construction, begin work with requirements and task workitems and follow the traditional sprint-based development lifecycle. Obviously, some minor training will be needed, but don’t fear, this is very intuitive and MSDN has a ton of lesson based labs and videos. 4. For the java developers, use the new Team Explorer Everywhere 2010 plugin (recently known as Teamprise). There is a seamless interface in Eclipse, but also a good command-line utility for other environments such as Dreamweaver. 5. Wait to fully integrate the whole workitem/project management/testing process until your team is familiar with the integrated workitems for bugs and code. After a while, you will see the team wanting more transparency into the work they are all doing and naturally, everyone will want workitems to help them organize the chaos! 6. Management will be limited in the value of the reports until you have a fully blown implementation of project planning, construction, build, deployment and testing. However, there are some basic “bug rate” reports and current backlog listings that can provide good information. Some notable explanations of TFS; Work Item Tracking and Project Management - A workitem represents the unit of work within the system which enables tracking of all activities produced by a user, whether it is a developer, business user, project manager or tester. The properties of a workitem such as linked changesets (checked-in code), who updated the data and when, the states and reasons for change, are all transitioned to a data warehouse within TFS for reporting purposes. A workitem can be defines as a "bug", "requirement", test case", or a "change request". They drive the work effort by the individual assigned to it and also provide a key role in defining what needs to be done. Workitems are the things the team needs to do to accomplish a goal. Test Case Management - Starting with a workitem known as a "test case", a tester (or developer) can now author and manage test cases within a formal test plan subsystem. Although TFS supports the test case workitem type, there is a new product known as the VS Test Professional 2010 which allows a tester to facilitate manual tests including fast forwarding steps in the process to arrive at the assertion point quickly. This repeatable process provides quick regression tests and can be conducted by the business user to ensure completeness during UAT. In addition, developers no longer can provide a response to a bug with the line "cannot reproduce". With every test run, attachments including the recorded session, captured environment configurations and settings, screen shots, intellitrace (debugging history), and in some cases if the lab manager is being used, a snapshot of the tested environment is available. Version Control - A modern system allowing shared check-in/check-out, excellent merge conflict resolution, Shelvesets (personal check-ins), branching/merging visualization, public workspaces, gated check-ins, security hierarchy capabilities, and changeset/workitem tracking. Knowing what was done with the code by any developer has become much easier to picture and resolve issues. Team Build - Automate the compilation process whether you need it to be whenever a developer checks-in code, periodically such as nightly builds for testers in the morning, or manual builds to be deployed into production. Each build can run through pre-determined tests, perform code analysis to see if the developer conforms to the team standards, and reject the build if either fails. Project Portal & Reporting - Provide management with a dashboard with insight into the project(s). "Where are we" in each step of the way including past iterations and the current burndown rate. Enabling this feature is easy as it seamlessly interfaces with existing SharePoint implementations.

The first day of JavaOne is already over!

- by delabassee

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

Functional Adaptation

- by Charles Courchaine

In real life and OO programming we’re often faced with using adapters, DVI to VGA, 1/4” to 1/8” audio connections, 110V to 220V, wrapping an incompatible interface with a new one, and so on. Where the adapter pattern is generally considered for interfaces and classes a similar technique can be applied to method signatures. To be fair, this adaptation is generally used to reduce the number of parameters but I’m sure there are other clever possibilities to be had. As Jan questioned in the last post, how can we use a common method to execute an action if the action has a differing number of parameters, going back to the greeting example it was suggested having an AddName method that takes a first and last name as parameters. This is exactly what we’ll address in this post. Let’s set the stage with some review and some code changes. First, our method that handles the setup/tear-down infrastructure for our WCF service: 1: private static TResult ExecuteGreetingFunc<TResult>(Func<IGreeting, TResult> theGreetingFunc) 2: { 3: IGreeting aGreetingService = null; 4: try 5: { 6: aGreetingService = GetGreetingChannel(); 7: return theGreetingFunc(aGreetingService); 8: } 9: finally 10: { 11: CloseWCFChannel((IChannel)aGreetingService); 12: } 13: } Our original AddName method: 1: private static string AddName(string theName) 2: { 3: return ExecuteGreetingFunc<string>(theGreetingService => theGreetingService.AddName(theName)); 4: } Our new AddName method: 1: private static int AddName(string firstName, string lastName) 2: { 3: return ExecuteGreetingFunc<int>(theGreetingService => theGreetingService.AddName(firstName, lastName)); 4: } Let’s change the AddName method, just a little bit more for this example and have it take the greeting service as a parameter. 1: private static int AddName(IGreeting greetingService, string firstName, string lastName) 2: { 3: return greetingService.AddName(firstName, lastName); 4: } The new signature of AddName using the Func delegate is now Func<IGreeting, string, string, int>, which can’t be used with ExecuteGreetingFunc as is because it expects Func<IGreeting, TResult>. Somehow we have to eliminate the two string parameters before we can use this with our existing method. This is where we need to adapt AddName to match what ExecuteGreetingFunc expects, and we’ll do so in the following progression. 1: Func<IGreeting, string, string, int> -> Func<IGreeting, string, int> 2: Func<IGreeting, string, int> -> Func<IGreeting, int> For the first step, we’ll create a method using the lambda syntax that will “eliminate” the last name parameter: 1: string lastNameToAdd = "Smith"; 2: //Func<IGreeting, string, string, int> -> Func<IGreeting, string, int> 3: Func<IGreeting, string, int> addName = (greetingService, firstName) => AddName(greetingService, firstName, lastNameToAdd); The new addName method gets us one step close to the signature we need. Let’s say we’re going to call this in a loop to add several names, we’ll take the final step from Func<IGreeting, string, int> -> Func<IGreeting, int> in line as a lambda passed to ExecuteGreetingFunc like so: 1: List<string> firstNames = new List<string>() { "Bob", "John" }; 2: int aID; 3: foreach (string firstName in firstNames) 4: { 5: //Func<IGreeting, string, int> -> Func<IGreeting, int> 6: aID = ExecuteGreetingFunc<int>(greetingService => addName(greetingService, firstName)); 7: Console.WriteLine(GetGreeting(aID)); 8: } If for some reason you needed to break out the lambda on line 6 you could replace it with 1: aID = ExecuteGreetingFunc<int>(ApplyAddName(addName, firstName)); and use this method: 1: private static Func<IGreeting, int> ApplyAddName(Func<IGreeting, string, int> addName, string lastName) 2: { 3: return greetingService => addName(greetingService, lastName); 4: } Splitting out a lambda into its own method is useful both in this style of coding as well as LINQ queries to improve the debugging experience. It is not strictly necessary to break apart the steps & functions as was shown above; the lambda in line 6 (of the foreach example) could include both the last name and first name instead of being composed of two functions. The process demonstrated above is one of partially applying functions, this could have also been done with Currying (also see Dustin Campbell’s excellent post on Currying for the canonical curried add example). Matthew Podwysocki also has some good posts explaining both Currying and partial application and a follow up post that further clarifies the difference between Currying and partial application. In either technique the ultimate goal is to reduce the number of parameters passed to a function. Currying makes it a single parameter passed at each step, where partial application allows one to use multiple parameters at a time as we’ve done here. This technique isn’t for everyone or every problem, but can be extremely handy when you need to adapt a call to something you don’t control.

Google Analytics - Unable to get GA Tracking

- by Pure.Krome

We've been using GA for a few years with no probs. About 2-3 weeks ago we tried to clean up some of our tracking and on one of our profiles, it's not working anymore (since oct 10.) First, some context then some GA Debugging code. 1. Context. We have the following setup: different root domains AND different sub-domains on one of the root domains. www.website.com www.website.com.au www.anotherWebsite.com foo.website.com baa.website.com So what we're doing is the following: each root domain and each sub-domain get their own tracking code. This way we can allow separate people (from outside our company) to access only their own data. Eg. a manager for foo.website.com can only see data related to that domain .. and see data on the other domains. Have a last account which is the SUM of all the domains. this is for us. so we can see total numbers. So to do this, we have two trackers that fire off, on the page. the individual accounts all work fine - they seem to be tracking data ok. the 'global' account is not working and this gives us the = Tracking Not Installed error. This has been going on since oct 10. So the wait 24/48/72 hours thing is waaaaay over. 2. GA Debug code. Installing GA Debug chrome extension gives the following output. I've tried to hide anything that could be considered secret. UA-XXXXX34-1 == Global account (which isn't working any more).

Anyone have any suggestions to help?

Scripting Part 1

- by rbishop

Dynamic Scripting is a large topic, so let me get a couple of things out of the way first. If you aren't familiar with JavaScript, I can suggest CodeAcademy's JavaScript series. There are also many other websites and books that cover JavaScript from every possible angle.The second thing we need to deal with is JavaScript as a programming language versus a JavaScript environment running in a web browser. Many books, tutorials, and websites completely blur these two together but they are in fact completely separate. What does this really mean in relation to DRM? Since DRM isn't a web browser, there are no document, window, history, screen, or location objects. There are no events like mousedown or click. Trying to call alert('hello!') in DRM will just cause an error. Those concepts are all related to an HTML document (web page) and are part of the Browser Object Model or Document Object Model. DRM has its own object model that exposes DRM-related objects. In practice, feel free to use those sorts of tutorials or practice within your browser; Many of the concepts are directly translatable to writing scripts in DRM. Just don't try to call document.getElementById in your property definition!I think learning by example tends to work the best, so let's try getting a list of all the unique property values for a given node and its children. var uniqueValues = {}; var childEnumerator = node.GetChildEnumerator(); while(childEnumerator.MoveNext()) { var propValue = childEnumerator.GetCurrent().PropValue("Custom.testpropstr1"); print(propValue); if(propValue != null && propValue != '' && !uniqueValues[propValue]) uniqueValues[propValue] = true; } var result = ''; for(var value in uniqueValues){ result += "Found value " + value + ","; } return result; Now lets break this down piece by piece. var uniqueValues = {}; This declares a variable and initializes it as a new empty Object. You could also have written var uniqueValues = new Object(); Why use an object here? JavaScript objects can also function as a list of keys and we'll use that later to store each property value as a key on the object. var childEnumerator = node.GetChildEnumerator(); while(childEnumerator.MoveNext()) { This gets an enumerator for the node's children. The enumerator allows us to loop through the children one by one. If we wanted to get a filtered list of children, we would instead use ChildrenWith(). When we reach the end of the child list, the enumerator will return false for MoveNext() and that will stop the loop. var propValue = childEnumerator.GetCurrent().PropValue("Custom.testpropstr1"); print(propValue); if(propValue != null && propValue != '' && !uniqueValues[propValue]) uniqueValues[propValue] = true; } This gets the node the enumerator is currently pointing at, then calls PropValue() on it to get the value of a property. We then make sure the prop value isn't null or the empty string, then we make sure the value doesn't already exist as a key. Assuming it doesn't we add it as a key with a value (true in this case because it makes checking for an existing value faster when the value exists). A quick word on the print() function. When viewing the prop grid, running an export, or performing normal DRM operations it does nothing. If you have a lot of print() calls with complicated arguments it can slow your script down slightly, but otherwise has no effect. But when using the script editor, all the output of print() will be shown in the Warnings area. This gives you an extremely useful debugging tool to see what exactly a script is doing. var result = ''; for(var value in uniqueValues){ result += "Found value " + value + ","; } return result; Now we build a string by looping through all the keys in uniqueValues and adding that value to our string. The last step is to simply return the result. Hopefully this small example demonstrates some of the core Dynamic Scripting concepts. Next time, we can try checking for node references in other hierarchies to see if they are using duplicate property values.

If the volume of traffic by our demo pods is any indicator, this is a record year for attendance at OpenWorld. The DIS team have had tremendous number of people stop by our demo pods to learn about the latest product releases or to speak to one of our product managers. For Oracle GoldenGate, there has been a great deal of interest in Integrated Capture and the Oracle GoldenGate Monitor plug-in for Enterprise Manager. Our customer panels this year have been very well attended and on Tuesday we held the “Real World Operational Reporting with Oracle GoldenGate Customer Panel”. On this panel this year we had Michael Wells from Raymond James, Joy Mathew and Venki Govindarajan from Comcast, and Serkan Karatas from Turk Telekom. Our panelists have a great mix of experiences and all are passionate about using Oracle Data Integration products to solve very complex use cases. Each panelist was given a ten minute to overview their use of our product, followed by a barrage of questions from the audience. Michael Wells spoke about using Oracle GoldenGate for heterogeneous real time replication from HP (Tandem) NonStop to SQL Server and emphasized the need for using standard naming conventions for when customers configure GoldenGate, as the practices is immensely helpful when debugging a problem. Joy Mathew and Venkat Govindarajan from Comcast described how they have used GoldenGate for over a decade and their experiences of using the product for replicating data from HP nonstop to Terdata. Serkan Karatas from Turk Telekom dove into using Oracle GoldenGate and the value of archiving data in extremely large databases, which in Turk Telekoms case resulted in a 1 month ROI for the entire project. Thanks again to our panelist and audience participants for making the session interactive and informative. For Wednesday we have a number of sessions available to attendees plus two hands-on labs, which I have listed below. If you are unable to attend our hands-on lab for Oracle GoldenGate Veridata, it is available online at youtube.com.
