• SQL SERVER – SOS_SCHEDULER_YIELD – Wait Type – Day 8 of 28

  - by pinaldave

  This is a very interesting wait type and quite often seen as one of the top wait types. Let us discuss this today. From Book On-Line: Occurs when a task voluntarily yields the scheduler for other tasks to execute. During this wait the task is waiting for its quantum to be renewed. SOS_SCHEDULER_YIELD Explanation: SQL Server has multiple threads, and the basic working methodology for SQL Server is that SQL Server does not let any “runnable” thread to starve. Now let us assume SQL Server OS is very busy running threads on all the scheduler. There are always new threads coming up which are ready to run (in other words, runnable). Thread management of the SQL Server is decided by SQL Server and not the operating system. SQL Server runs on non-preemptive mode most of the time, meaning the threads are co-operative and can let other threads to run from time to time by yielding itself. When any thread yields itself for another thread, it creates this wait. If there are more threads, it clearly indicates that the CPU is under pressure. You can fun the following DMV to see how many runnable task counts there are in your system. SELECT scheduler_id, current_tasks_count, runnable_tasks_count, work_queue_count, pending_disk_io_count FROM sys.dm_os_schedulers WHERE scheduler_id < 255 GO If you notice a two-digit number in runnable_tasks_count continuously for long time (not once in a while), you will know that there is CPU pressure. The two-digit number is usually considered as a bad thing; you can read the description of the above DMV over here. Additionally, there are several other counters (%Processor Time and other processor related counters), through which you can refer to so you can validate CPU pressure along with the method explained above. Reducing SOS_SCHEDULER_YIELD wait: This is the trickiest part of this procedure. As discussed, this particular wait type relates to CPU pressure. Increasing more CPU is the solution in simple terms; however, it is not easy to implement this solution. There are other things that you can consider when this wait type is very high. Here is the query where you can find the most expensive query related to CPU from the cache Note: The query that used lots of resources but is not cached will not be caught here. SELECT SUBSTRING(qt.TEXT, (qs.statement_start_offset/2)+1, ((CASE qs.statement_end_offset WHEN -1 THEN DATALENGTH(qt.TEXT) ELSE qs.statement_end_offset END - qs.statement_start_offset)/2)+1), qs.execution_count, qs.total_logical_reads, qs.last_logical_reads, qs.total_logical_writes, qs.last_logical_writes, qs.total_worker_time, qs.last_worker_time, qs.total_elapsed_time/1000000 total_elapsed_time_in_S, qs.last_elapsed_time/1000000 last_elapsed_time_in_S, qs.last_execution_time, qp.query_plan FROM sys.dm_exec_query_stats qs CROSS APPLY sys.dm_exec_sql_text(qs.sql_handle) qt CROSS APPLY sys.dm_exec_query_plan(qs.plan_handle) qp ORDER BY qs.total_worker_time DESC -- CPU time You can find the most expensive queries that are utilizing lots of CPU (from the cache) and you can tune them accordingly. Moreover, you can find the longest running query and attempt to tune them if there is any processor offending code. Additionally, pay attention to total_worker_time because if that is also consistently higher, then  the CPU under too much pressure. You can also check perfmon counters of compilations as they tend to use good amount of CPU. Index rebuild is also a CPU intensive process but we should consider that main cause for this query because that is indeed needed on high transactions OLTP system utilized to reduce fragmentations. Note: The information presented here is from my experience and there is no way that I claim it to be accurate. I suggest reading Book OnLine for further clarification. All of the discussions of Wait Stats in this blog is generic and varies from system to system. It is recommended that you test this on a development server before implementing it to a production server.

• Exploring packages in code

  In my previous post Searching for tasks with code you can see how to explore the control flow side of packages, drilling down through containers, task, and event handlers, but it didn’t cover the data flow. I recently saw a post on the MSDN forum asking how to edit an existing package programmatically, and the sticking point was how to find the the data flow and the components inside. This post builds on some of the previous code and shows how you can explore all objects inside a package. I took the sample Task Search application I’d written previously, and came up with a totally pointless little console application that just walks through the package and writes out the basic type and name of every object it finds, starting with the package itself e.g. Package – MyPackage . The sample package we used last time showed nested objects as well an event handler; a OnPreExecute event tucked away on the task SQL In FEL. The output of this sample tool would look like this: PackageObjects v1.0.0.0 (1.0.0.26627) Copyright (C) 2009 Konesans Ltd Processing File - Z:\Users\Darren Green\Documents\Visual Studio 2005\Projects\SSISTestProject\EventsAndContainersWithExe cSQLForSearch.dtsx Package - EventsAndContainersWithExecSQLForSearch For Loop - FOR Counter Loop Task - SQL In Counter Loop Sequence Container - SEQ For Each Loop Wrapper For Each Loop - FEL Simple Loop Task - SQL In FEL Task - SQL On Pre Execute for FEL SQL Task Sequence Container - SEQ Top Level Sequence Container - SEQ Nested Lvl 1 Sequence Container - SEQ Nested Lvl 2 Task - SQL In Nested Lvl 2 Task - SQL In Nested Lvl 1 #1 Task - SQL In Nested Lvl 1 #2 Connection Manager – LocalHost The code is very similar to what we had previously, but there are a couple of extra bits to deal with connections and to look more closely at a task and see if it is a Data Flow task. For connections your just examine the package's Connections collection as shown in the abridged snippets below. First you can see the call to the ProcessConnections method, followed by the method itself. // Load the package file Application application = new Application(); using (Package package = application.LoadPackage(filename, null)) { // Write out the package name Console.WriteLine("Package - {0}", package.Name); ... More ... // Look and the connections ProcessConnections(package.Connections); } private static void ProcessConnections(Connections connections) { foreach (ConnectionManager connectionManager in connections) { Console.WriteLine("Connection Manager - {0}", connectionManager.Name); } } What we didn’t see in the sample output above was anything to do with the Data Flow, but rest assured the code now handles it too. The following snippet shows how each task is examined to see if it is a Data Flow task, and if so we can then loop through all of the components inside the data flow. private static void ProcessTaskHost(TaskHost taskHost) { if (taskHost == null) { return; } Console.WriteLine("Task - {0}", taskHost.Name); // Check if the task is a Data Flow task MainPipe pipeline = taskHost.InnerObject as MainPipe; if (pipeline != null) { ProcessPipeline(pipeline); } } private static void ProcessPipeline(MainPipe pipeline) { foreach (IDTSComponentMetaData90 componentMetadata in pipeline.ComponentMetaDataCollection) { Console.WriteLine("Pipeline Component - {0}", componentMetadata.Name); // If you wish to make changes to the component then you should really use the managed wrapper. // CManagedComponentWrapper wrapper = componentMetadata.Instantiate(); // wrapper.SetComponentProperty("PropertyName", "Value"); } } Hopefully you can see how we get a reference to the Data Flow task, and then use the ComponentMetaDataCollection to find out what components we have inside the pipeline. If you wanted to know more about the component you could look at the ObjectType or ComponentClassID properties. After that it gets a bit harder and you should get a reference to the wrapper object as the comment suggest and start using the properties, just like you would in the create packages samples, see our Code Development category for some for these examples.

• Updated Security Baseline (7u45) impacts Java 7u40 and before with High Security settings

  - by costlow

  The Java Security Baseline has been increased from 7u25 to 7u45.  For versions of Java below 7u45, this means unsigned Java applets or Java applets that depend on Javascript LiveConnect calls will be blocked when using the High Security setting in the Java Control Panel. This issue only affects Applets and Web Start applications. It does not affect other types of Java applications. The Short Answer Users upgrading to Java 7 update 45 will automatically fix this and is strongly recommended. The More Detailed Answer There are two items involved as described on the deployment flowchart: The Security Baseline – a dynamically updated attribute that checks to see which Java version contains the most recent security patches. The Security Slider – the user-controlled setting of when to prompt/run/block applets. The Security Baseline Java clients periodically check in to understand what version contains the most recent security patches. Versions are released in-between that contain bug fixes. For example: 7u25 (July 2013) was the previous secure baseline. 7u40 contained bug fixes. Because this did not contain security patches, users were not required to upgrade and were welcome to remain on 7u25. When 7u45 was released (October, 2013), this critical patch update contained security patches and raised the secure baseline. Users are required to upgrade from earlier versions. For users that are not regularly connected to the internet, there is a built in Expiration Date. Because of the pre-established quarterly critical patch updates, we are able to determine an approximate date of the next version. A critical patch released in July will have its successor released, at latest, in July + 3 months: October. The Security Slider The security slider is located within the Java control panel and determines which Applets & Web Start applications will prompt, which will run, and which will be blocked. One of the questions used to determine prompt/run/block is, “At or Above the Security Baseline.” The Combination JavaScript calls made from LiveConnect do not reside within signed JAR files, so they are considered to be unsigned code. This is correct within networked systems even if the domain uses HTTPS because signed JAR files represent signed "data at rest" whereas TLS (often called SSL) literally stands for "Transport Level Security" and secures the communication channel, not the contents/code within the channel. The resulting flow of users who click "update later" is: Is the browser plug-in registered and allowed to run? Yes. Does a rule exist for this RIA? No rules apply. Does the RIA have a valid signature? Yes and not revoked. Which security prompt is needed? JRE is below the baseline. This is because 7u45 is the baseline and the user, clicked "upgrade later." Under the default High setting, Unsigned code is set to "Don’t Run" so users see: Additional Notes End Users can control their own security slider within the control panel. System Administrators can customize the security slider during automated installations. As a reminder, in the future, Java 7u51 (January 2014) will block unsigned and self-signed Applets & Web Start applications by default.

• Framework 4 Features: Support for Timed Jobs

  - by Anthony Shorten

  One of the new features of the Oracle Utilities Application Framework V4 is the ability for the batch framework to support Timed Batch. Traditionally batch is associated with set processing in the background in a fixed time frame. For example, billing customers. Over the last few versions their has been functionality required by the products required a more monitoring style batch process. The monitor is a batch process that looks for specific business events based upon record status or other pieces of data. For example, the framework contains a fact monitor (F1-FCTRN) that can be configured to look for specific status's or other conditions. The batch process then uses the instructions on the object to determine what to do. To support monitor style processing, you need to run the process regularly a number of times a day (for example, every ten minutes). Traditional batch could support this but it was not as optimal as expected (if you are a site using the old Workflow subsystem, you understand what I mean). The Batch framework was extended to add additional facilities to support times (and continuous batch which is another new feature for another blog entry). The new facilities include: The batch control now defines the job as Timed or Not Timed. Non-Timed batch are traditional batch jobs. The timer interval (the interval between executions) can be specified The timer can be made active or inactive. Only active timers are executed. Setting the Timer Active to inactive will stop the job at the next time interval. Setting the Timer Active to Active will start the execution of the timed job. You can specify the credentials, language to view the messages and an email address to send the a summary of the execution to. The email address is optional and requires an email server to be specified in the relevant feature configuration. You can specify the thread limits and commit intervals to be sued for the multiple executions. Once a timer job is defined it will be executed automatically by the Business Application Server process if the DEFAULT threadpool is active. This threadpool can be started using the online batch daemon (for non-production) or externally using the threadpoolworker utility. At that time any batch process with the Timer Active set to Active and Batch Control Type of Timed will begin executing. As Timed jobs are executed automatically then they do not appear in any external schedule or are managed by an external scheduler (except via the DEFAULT threadpool itself of course). Now, if the job has no work to do as the timer interval is being reached then that instance of the job is stopped and the next instance started at the timer interval. If there is still work to complete when the interval interval is reached, the instance will continue processing till the work is complete, then the instance will be stopped and the next instance scheduled for the next timer interval. One of the key ways of optimizing this processing is to set the timer interval correctly for the expected workload. This is an interesting new feature of the batch framework and we anticipate it will come in handy for specific business situations with the monitor processes.

• Uncovering Compiler Errors in ASP.NET MVC Views

  - by Ben Griswold

  ASPX and ASCX files are compiled on the fly when they are requested on the web server. This means it’s possible that you aren’t catching compile errors associated with your views when you build your ASP.NET MVC project in Visual Studio.  Unless you’re willing to click through your entire application, rendering each view looking for errors, you application is left a little vulnerable to user issues.  Fortunately, there’s a work around.  Open up your MVC project file in notepad or within the Visual Studio IDE by unloading the project and then editing the .csproj file (both actions are available by right-clicking on the Project Node in Solution Explorer.)  Notice the MvcBuildViews option.  It’s probably set to false.  Flip the value to true and you’ll magically start compiling your views when you build your application. <MvcBuildViews>false</MvcBuildViews> Taking this action will slow down your builds a bit, but if you’re a hack like me, it’ll probably save your day in the long run. Now you’re probably thinking, “Neat trick – how’s it work?”  Scroll down toward the bottom of your csproj file and you will notice the AfterBuild target triggers the AspNetCompiler action if the MvcBuildViews option is set to true.  <Target Name="AfterBuild" Condition="'$(MvcBuildViews)'=='true'">   <AspNetCompiler VirtualPath="temp"                   PhysicalPath="$(ProjectDir)\..\$(ProjectName)" /> </Target> Great. One more thing. Let’s say you don’t want to slow down all of your builds, but you absolutely want to know if there are any compiler issues with your views before you commit your code to version control or deploy or whatever.  Here’s what you can do – change the AfterBuild condition to run if your configuration is set to Release mode.  <Target Name="AfterBuild" Condition="'$(Configuration)'=='Release'">   <!– Always pre-compile ASPX and ASCX in release mode –>   <AspNetCompiler VirtualPath="temp"                   PhysicalPath="$(ProjectDir)\..\$(ProjectName)" /> </Target> Now your debug mode builds will continue to be as fast as ever and you can quickly validate your views by building in release mode when you so choose.  There’s one little catch – this setup won’t consider the MvcBuildViews option whatsoever! So if you decide to go with this configuration, you might want to add a comment near the MvcBuildViews option letting other developers know they can change the MvcBuildViews option as much as they’d like but it’s not going to affect the AfterBuild action.  Or don’t include the comment and let your team members figure it out for themselves…

• POP Forums v9 Beta 1 for ASP.NET MVC 3 posted to CodePlex!

  - by Jeff

  As promised, I posted a beta build of my forum app for ASP.NET MVC 3. Get the new goodies here: http://popforums.codeplex.com/releases/view/58228 This is the first beta for the ASP.NET MVC 3 version of POP Forums. It is nearly feature complete, and ready for testing and feedback. For previous release notes, look here, here and here.Check out the live preview: http://preview.popforums.com/ForumsSetup instructions are on the home page of this project. The new hotness in the beta, or what has been done since the last preview: All views converted to use Razor E-mail subscription/notification of new posts New post indicators/mark read buttons Permalinks to posts Jump to newest post (from new post indicators) Recent topics Favorite topics Moderator functions for topics (pin/close/delete, plus move and rename) Search, ported from v8. Not a ton of optimization here, or new unit testing, but the old version worked pretty well User posts (topics the user posted in) Forgot password Vanity items (signatures and avatars) Hide vanity items per user preference Some minor data caching where appropriate A little bit of UI refinement Lots-o-bug fixes Lots-o-unit tests What's next? The plan between now and the next beta is as follows: Continue working through features/tasks, and fix bugs as they're reported Integrate the forum into a real, production site Refine the UI Refactor as much as possible... the code organization is not entirely logical in some places After the second beta, a release candidate will follow, with a real "final" release after that. Subsequent releases should come relatively frequently and without a lot of risk. The trick in building this thing has been that it mostly tossed the previous WebForms version, which was all full of crusties. The time table for this is a little harder to pin down, as day jobs and families will have their effect. Other notes Refactoring will be a priority. As the features of MVC have evolved, so have my desires to use it in a fashion that makes things clear and easy to follow. I don't even know if anyone will ever start mucking around in the code, but on the off chance they do, I'd like what they find to not suck. Other nice-to-haves are builds to target Windows Azure and SQL CE. A nice setup UI would be super too. I think the ASP.NET MVC world has gone long enough without a decent forum.The biggest challenge that I've found is making the forum something that can be dropped in any app. While it does rope its views into an area, areas are mostly just routing details. I haven't thought of a clever way yet to limit dependency injection, for example, to just the forum bits. I mean, everyone should be using Ninject, but how realistic is that? ;)How much time and effort should you spend on POP Forums in its current state? Change is inevitable, but at this point I'm reasonably committed to not changing the database schema. I really think it will stay as-is. All bets are off for the various interfaces throughout the app, but the data should generally resist change. It's not even that different from v8, which was one of the original goals because I didn't want to rewrite SQL or introduce a new ORM or whatever. My point is that if you wanted to build a site around this today, even though it's not entirely functional, I think it's low risk in terms of data loss. I can't vouch for whether or not you know what you're doing.I've been having some chats with people lately about quoting posts, and honestly there has to be something better and straight forward. That continues to be a holy grail of mine, and some day, I hope to find it.Enjoy... it's starting to feel more real every day!

• SQL SERVER – Data Pages in Buffer Pool – Data Stored in Memory Cache

  - by pinaldave

  This will drop all the clean buffers so we will be able to start again from there. Now, run the following script and check the execution plan of the query. Have you ever wondered what types of data are there in your cache? During SQL Server Trainings, I am usually asked if there is any way one can know how much data in a table is stored in the memory cache? The more detailed question I usually get is if there are multiple indexes on table (and used in a query), were the data of the single table stored multiple times in the memory cache or only for a single time? Here is a query you can run to figure out what kind of data is stored in the cache. USE AdventureWorks GO SELECT COUNT(*) AS cached_pages_count, name AS BaseTableName, IndexName, IndexTypeDesc FROM sys.dm_os_buffer_descriptors AS bd INNER JOIN ( SELECT s_obj.name, s_obj.index_id, s_obj.allocation_unit_id, s_obj.OBJECT_ID, i.name IndexName, i.type_desc IndexTypeDesc FROM ( SELECT OBJECT_NAME(OBJECT_ID) AS name, index_id ,allocation_unit_id, OBJECT_ID FROM sys.allocation_units AS au INNER JOIN sys.partitions AS p ON au.container_id = p.hobt_id AND (au.type = 1 OR au.type = 3) UNION ALL SELECT OBJECT_NAME(OBJECT_ID) AS name, index_id, allocation_unit_id, OBJECT_ID FROM sys.allocation_units AS au INNER JOIN sys.partitions AS p ON au.container_id = p.partition_id AND au.type = 2 ) AS s_obj LEFT JOIN sys.indexes i ON i.index_id = s_obj.index_id AND i.OBJECT_ID = s_obj.OBJECT_ID ) AS obj ON bd.allocation_unit_id = obj.allocation_unit_id WHERE database_id = DB_ID() GROUP BY name, index_id, IndexName, IndexTypeDesc ORDER BY cached_pages_count DESC; GO Now let us run the query above and observe the output of the same. We can see in the above query that there are four columns. Cached_Pages_Count lists the pages cached in the memory. BaseTableName lists the original base table from which data pages are cached. IndexName lists the name of the index from which pages are cached. IndexTypeDesc lists the type of index. Now, let us do one more experience here. Please note that you should not run this test on a production server as it can extremely reduce the performance of the database. DBCC DROPCLEANBUFFERS This will drop all the clean buffers and we will be able to start again from there. Now run following script and check the execution plan for the same. USE AdventureWorks GO SELECT UnitPrice, ModifiedDate FROM Sales.SalesOrderDetail WHERE SalesOrderDetailID BETWEEN 1 AND 100 GO The execution plans contain the usage of two different indexes. Now, let us run the script that checks the pages cached in SQL Server. It will give us the following output. It is clear from the Resultset that when more than one index is used, datapages related to both or all of the indexes are stored in Memory Cache separately. Let me know what you think of this article. I had a great pleasure while writing this article because I was able to write on this subject, which I like the most. In the next article, we will exactly see what data are cached and those that are not cached, using a few undocumented commands.

• SQL SERVER – A Picture is Worth a Thousand Words – A Collection of Inspiring and Funny Posts by Vinod Kumar

  - by pinaldave

  One of the most popular quotes is: A picture is worth a thousand words. Working on this concept I started a series over my blog called the “Picture Post”. Rather than rambling over tons of material over text, we are trying to give you a capsule mode of the blog in a quick glance. Some of the picture posts already available over my blog are: Correlation of Ego and Work: Ego and Pride most of the times become a hindrance when we work inside a team. Take this cue, the first ever Picture post was published. Simple and easy to understand concept. Would want to say, Ego is the biggest enemy to humans. Read Original Post. Success (Perception Vs Reality): Personally, have always thought success is not something the talented achieve with the opportunity presented to them, but success is developed using the opportunity in hand now. In this fast paced world where success is pre-defined and convoluted by metrics it is hard to understand how complex it can sometimes be. So I took a stab at this concept in a simple way. Read Original Post. Doing Vs Saying: As Einstein would describe, Insanity is doing the same thing over and over again and expecting different results. Given the amount of information we get, it is difficult to keep track, learn and implement the same. If you were ever reminded of your college days, there will always be 5-6 people doing different things and we naturally try to emulate what they are doing. This could be from competitive exams GMAT, GRE, CAT, Higher-Ed, B-School hunting etc. Rather than saying you are going to do, it is best to do and then say!!! Read Original Picture Post. Your View Vs Management View: Being in the corporate world can be really demanding and we keep asking this question – “Why me?” when the performance appraisal process ends. In this post I just want to ask you one frank opinion – “Are you really self-critical in your assessments?”. If that is the case there shouldn’t be any heartburns or surprises. If you had just one thing to take back, well forget what others are getting but invest time in making yourself better because that is going to take you longer and further in your career. Read Picture Post. Blogging lifecycle for majority: I am happy and fortunate to be in this blog post because this picture post surely doesn’t apply to SQLAuthority where consistency and persistence have been the hallmark of the blog. For the majority others, who have a tendency to start a blog, get into slumber for a while and write saying they want to get back to blogging, the picture post was specifically done for them. Paradox of being someone else: It is always a dream that we want to become somebody and in this process of doing so, we become nobody. In this constant tussle of lost identity we forget to enjoy the moment that is in front of us. I just depicted this using a simple analogy of our constant struggle to get to the other side, just to realize we missed the wonderful moments. Grass is not greener on the other side, but grass is greener where we water the surface. Read Picture Post. And on the lighter side… Reference: Pinal Dave (http://blog.SQLAuthority.com) Filed under: About Me, PostADay, SQL, SQL Authority, SQL Query, SQL Server, SQL Tips and Tricks, T SQL, Technology

• Create Music Playlists in Windows 7 Media Center

  - by DigitalGeekery

  One of the new features in Windows 7 Media Center is the ability to easily create music playlists without using Media Player. Today we’ll take a closer look at how to create them directly in Media Center. Create Manual Playlists Open Windows Media Center and select the Music Library. From within the Music Library, choose playlists from the top menu.   Then select Create Playlist. Give your new playlist a name, and select Next. Choose Music Library and select Next.    Select “songs” from the top menu, choose the songs for your playlist from your library, and select Next when finished. You can also click Select All to add all songs to your playlist, or clear all to remove them. Note: you can also sort by artist, album, genre, etc. from the top menu.   Now you can review and edit your playlist. Click the up and down pointers to move songs up and down in the playlist, or “X” to remove them. You can also go back and add additional songs by selecting Add More. Click Create when you are finished.   Auto Playlists Windows Media Center also allows you to create six different auto playlists. These are dynamic playlists based on pre-defined criteria. Auto Playlists include All Music, Music added in the last month, Music auto rated at 5 stars, Music played in the last month, Music played the most, and Music rated 4 or 5 stars. These Auto Playlists will change dynamically as your library and listening habits change. Your new music playlists can be found under playlists in the music library. Select play playlist to start the music. Now kick back and enjoy the music from your playlist. Conclusion While earlier versions of WMC allowed you to create playlists, you had to do it through Windows Media Player. This is a nice new feature for music lovers who use WMC and prefer to do everything with a remote. Do you already have playlists that you’ve created in Windows Media Player? Windows Media Center can play those too. If your playlists are in the default Music folder, Media Center will detect them automatically and add them to your Music Library. Plus, any playlists you create in Media Center are also available for Media Player. For more on creating Playlists in Media Player, check out our previous articles on how to create a custom playlist in Windows Media Player 12, and how to create auto playlists in WMP 12.

• Manage Your WordPress Blog Comments from Your Windows Desktop

  - by Matthew Guay

  Are you never more than a few steps away from your PC and want to keep up with comments on your blog?  Then here’s how you can stay on top of your WordPress comments right from your desktop. Wp-comment-notifier is a small free app for Windows that lets you easily view, approve, reply to, and delete comments from your WordPress blog.  Whether you have a free WordPress.com blog or are running WordPress on your own server, this tool can keep you connected to your comments.  Unfortunately it only lets you manage comments at one blog, so if manage multiple WordPress-powered sites you may find this a downside.  Otherwise, it works great and helps you stay on top of the conversation at your blog. Get notified with wp-comment-notifier Download the wp-comment-notifier (link below) and install as usual. Run it once it’s installed.  Enter your blog address, username, and password when prompted. Wp-comment-notifier will automatically setup your account and download recent comments. Finally, enter your blog’s name, and click Finish. Review Comments with wp-comment-notifier You can now review your comments directly by double-clicking the new WordPress icon in your system tray.  The window has 3 tabs…comments, pending, and spam.  Select a comment to reply, edit, spam, or delete it directly from your desktop. If you select Edit, then you can edit the HTML of the comment (including links) directly from within the notifier. You can approve or permanently delete any spam messages that are caught by your blog’s spam filter. Whenever new comments come in, you’ll see a tray popup letting you know how many comments are waiting to be approved or are in the spam folder.  Click the popup to open the editor. Now, you can directly approve that pending comment without going to your WordPress admin page.  When you’re done, just press Enter on your Keyboard to post the reply. Or, if you want to reply to the comment, click the reply link and enter your comment in the entry box at the bottom. If you ever want to double-check if there’s any new comments, just right-click on the tray icon and select refresh. Finally, you can change the settings from the Configuration link in the tray button or by clicking the gear button on the bottom of the review window.  You can change how often it checks for new comments, not to start the notifier at system startup, and edit your account information.

Register before July 1, 2012 to qualify for discounts. Visit the Registration page for details. The International SOA, Cloud + Service Technology Symposium is a yearly event that features the top experts and authors from around the world, providing a series of keynotes, talks, demonstrations, and panels, as well as training and certification workshops - all dedicated to empowering IT professionals to realize modern service technologies and practices in the real world. Click here for a two-page printable conference overview (PDF). Big Data with CEP and SOA - September 25, 2012 - 14:15 Speaker: Markus Zirn, Oracle and Baz Kuthi, Avocent The "Big Data" trend is driving new kinds of IT projects that process machine-generated data. Such projects store and mine using Hadoop/ Map Reduce, but they also analyze streaming data via event-driven patterns, which can be called "Fast Data" complementary to "Big Data". This session highlights how "Big Data" and "Fast Data" design patterns can be combined with SOA design principles into modern, event-driven architectures. We will describe specific architectures that combines CEP, Distributed Caching, Event-driven Network, SOA Composites, Application Development Framework, as well as Hadoop. Architecture patterns include pre-processing and filtering event streams as close as possible to the event source, in memory master data for event pattern matching, event-driven user interfaces as well as distributed event processing. Focus is on how "Fast Data" requirements are elegantly integrated into a traditional SOA architecture. Markus Zirn is Vice President of Product Management covering Oracle SOA Suite, SOA Governance, Application Integration Architecture, BPM, BPM Solutions, Complex Event Processing and UPK, an end user learning solution. He is the author of “The BPEL Cookbook” (rated best book on Services Oriented Architecture in 2007) as well as “Fusion Middleware Patterns”. Previously, he was a management consultant with Booz Allen & Hamilton’s High Tech practice in Duesseldorf as well as San Francisco and Vice President of Product Marketing at QUIQ. Mr. Zirn holds a Masters of Electrical Engineering from the University of Karlsruhe and is an alumnus of the Tripartite program, a joint European degree from the University of Karlsruhe, Germany, the University of Southampton, UK, and ESIEE, France.

• Customize Team Build 2010 – Part 12: How to debug my custom activities

  In the series the following parts have been published Part 1: Introduction Part 2: Add arguments and variables Part 3: Use more complex arguments Part 4: Create your own activity Part 5: Increase AssemblyVersion Part 6: Use custom type for an argument Part 7: How is the custom assembly found Part 8: Send information to the build log Part 9: Impersonate activities (run under other credentials) Part 10: Include Version Number in the Build Number Part 11: Speed up opening my build process template Part 12: How to debug my custom activities Part 13: Get control over the Build Output Part 14: Execute a PowerShell script Part 15: Fail a build based on the exit code of a console application       Developers are “spoilt” persons who expect to be able to have easy debugging experiences for every technique they work with. So they also expect it when developing custom activities for the build process template. This post describes how you can debug your custom activities without having to develop on the build server itself. Remote debugging prerequisites The prerequisite for these steps are to install the Microsoft Visual Studio Remote Debugging Monitor. You can find information how to install this at http://msdn.microsoft.com/en-us/library/bt727f1t.aspx. I chose for the option to run the remote debugger on the build server from a file share. Debugging symbols prerequisites To be able to start the debugging, you need to have the pdb files on the buildserver together with the assembly. The pdb must have been build with Full Debug Info. Steps In my setup I have a development machine and a build server. To setup the remote debugging, I performed the following steps Locate on your development machine the folder C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\Remote Debugger Create a share for the Remote Debugger folder. Make sure that the share (and the folder) has the correct permissions so the user on the build server has access to the share. On the build server go to the shared “Remote Debugger” folder Start msvsmon.exe which is located in the folder that represents the platform of the build server. This will open a winform application like   Go back to your development machine and open the BuildProcess solution. Start the Attach to process command (Ctrl+Alt+P) Type in the Qualifier the name of the build server. In my case the user account that has started the msvsmon is another user then the user on my development machine. In that case you have to type the qualifier in the format that is shown in the Remote Debugging Monitor (in my case LOCAL\Administrator@TFSLAB) and confirm it by pressing <Enter> Since the build service is running with other credentials, check the option “Show processes from all users”. Now the Attach to process dialog shows the TFSBuildServiceHost process Set the breakpoint in the activity you want to debug and kick of a build. Be aware that when you attach to the TFSBuildServiceHost that you debug every single build that is run by this windows service, so make sure you don’t debug the build server that is in production! You can download the full solution at BuildProcess.zip. It will include the sources of every part and will continue to evolve.

• Databases in Source Control

  - by Grant Fritchey

  I’ve been working as a database professional for quite a long time. But originally, I was a developer. And I loved being a developer. There was this constant feedback loop of a job well done, your code compiled and it ran. Every time this happened successfully, you’d check it into source control. These days you have to add another step; the code passed all the tests, unit, line, regression, qa, whatever, then into source control it goes. As a matter of fact, when I first made the jump from developer to DBA/database developer/database professional, source control was the one thing I couldn’t believe was missing from the DBA toolbox. Come to find out, source control was only the beginning of what was missing from your standard DBAs set of skills. Don’t get me wrong. I’m not disrespecting the DBA. They’re focused where they should be, on your production data. But there has to be a method for developing applications that include databases and the database side of that development and deployment process has long been lacking. This lack of development and deployment methodologies is a part of what has given rise to some of the wackier implementations of Object Relational Mapping tools, the NoSQL movement, and some of the other foul cursing that is directed towards databases, DBAs, and database development by application developers. Some of that is well earned. A lot isn’t. But it is a fact that database professionals, in general, do not have as sophisticated a model for managing development and deployment as application developers do. We could charge out and start trying to come up with our own standards and methods. I’m sure people have done exactly that. However, I’m lazy, and not terribly bright. Rather than try to invent a whole new process, I’m going to look to my developer roots and choose instead to emulate the developers. They’re sitting over there across the hall from me working with SCRUM/Agile/Waterfall/Object Driven/Feature Driven/Test Driven development processes that they’ve been polishing for years. What if I just started working on database development the same way they work on code development? Win! Ah, but now I have to have a mechanism for treating my database like application code. First, I need a method for getting it into source control. That’s where Red Gate’s SQL Source Control comes into the picture. SQL Source Control works within SQL Server Management Studio to connect your database objects up to the source control system of your choice. Right out of the box SQL Source Control can link to TFS, SVN or Vault. With a little work you can connect it to Git or just about any other source control system. With the ability to get my database into source control, a lot of possibilities for more direct integration with the application development teams open up.

• Outlook 2010 – My Top 9 features

  - by Daniel Moth

  Office 2010 has reached RTM. Here are my favorite Outlook features. Speed. It is faster than previous versions and hangs much less… Ignore Conversation (Ctrl+Del). Not interested in a conversation? Click this button on the new ribbon and you'll never receive another message on that thread (they all go to your Deleted folder). Calendar Preview. When receiving a Meeting Request, before deciding to accept or not you get to see a preview of your calendar for that day and where the new meeting would fit in. See full description on outlook team blog post. Quick Steps. See full description on outlook team blog post. I have created my own quick steps for filing conversations to folders, various pre-populated reply templates, creating calendar invites and creating TODOs from received emails. Search Interface. Many of us knew the magic keywords for making smart searches (e.g. from:Name), but it is great to learn many more through the search tools contextual ribbon tab. Next 7 days. Out of the many enhancements to the Calendar view, my favorite is to be able with  single click to view the next 7 days – that is now my default view. MailTips. See full description on outlook team blog post. The ones I particularly like are when composing a mail to someone that has their Out Of Office reply set, you get to read it before sending the mail (and hence can decide to postpone sending). when composing a mail to a distribution list, a message informs you of the number of recipients. Hopefully, senders will use that as a clue for narrowing down the recipient list or at least verifying that their mail should indeed be sent to so many people. "You are not responding to the latest message in this conversation. Click here to open it.". When composing a reply to a conversation and you have not picked the last message to reply to (don't you hate it when people split threads like that?), this is the inline message you see (under the MailTips area) and if you click on the message it opens the last mail in the conversation so you can reply to that. Rich "Conversation Settings" and in particular "Show Messages from Other Folders". For example, you can see in your inbox not only the message you received but also the reply you sent (it gets pulled in from the Sent folder). Another example: a conversation has been taking place on a distribution list (so your rules filed it to a folder) and they add you on the TO or CC line, so it appears in a different folder; regardless of which folder you open, you are able to see the entire conversation. Note that messages from other folders than the one you are browsing, appear in grey text so you can easily spot them. Reading them in one folder, obviously marks them as read in the other folder… If you haven't yet, when are you making the move to Outlook 2010? Comments about this post welcome at the original blog.

• NServiceBus Generic Host and mqsvc.exe high CPU

  - by Michael Stephenson

  We have been doing some work with NServiceBus recently and observed some unusual behaviour which was caused by our mistake and seemed worthy of a small post.   The Scenario In our solution we were doing some standard NServiceBus stuff by pushing a message to a queue using NServiceBus.  We had a direct send/receive scenario rather than a publish/subscribe one.   The background process which was meant to collect the message and then process it was a normal NServiceBus message handler.  We would run the NServiceBus.Host.exe which would find the handler and then do the usual NServiceBus magic.   The Problem In this solution we were creating some automated tests around this module of the integration process to ensure that it would work well.  We had two tests.   Test 1 This test would start NServiceBus.Host.exe using the Process object, then seed a message to the queue via our web service façade sitting above the queue which wrapped NServiceBus.  The background process would then process the message and the test would check the message had been processed fine.   If all was well then the NServiceBus.Host.exe process was stopped.   Test 2 In test 2 we would do a very similar thing except that instead of starting the process the test would install NServiceBus.Host.exe as a windows service and then start the service before the test and once the test was executed it would stop the test.   The Results of the Tests Test 1 worked really well, however in test 2 we found that it didn’t really work at all, instead of doing the background process we were finding that between mqsvc.exe and NServiceBus.Host.exe the CPU on the machine was maxed and nothing was really happening.   The Solution After trying a few things we found it was the permissions on the queue were not set correctly.  Once this was resolved it all worked fine and CPU was not excessive and ran just like the console application.   I think the couple of take aways from this are:   Make sure you set the windows service for NserviceBus Generic Host to the right credentials When you install the generic host as a windows service then by default it will use the default windows credentials.  For any production like scenario you should be using a domain account to run the process as via the windows service. Make sure you have the queue set with the right permissions For the credentials you have used to configure the generic host as a windows service you should ensure that this user has the appropriate permissions for any queues it will interact with. Make sure you turn on the right logging configuration in NServiceBus When this wasnt working correctly we didnt know there was an issue, we were just experiencing the high CPU condition.  I am a little surprised that there wasnt something logged and that the process didnt crash.  I guess this could be by design bearing in mind that the process could be monitoring many queues.  In this point Im just saying that originally we didnt have all of the log4net logging which is available from NServiceBus turned on.  Its probably a good idea to have this turned on and configured until you are happy your solution is working fine.   Thanks to Ahmed Hashmi on my team who got this working in the end.

• Using NServiceBus behind a custom web service

  - by Michael Stephenson

  In this post I'd like to talk about an architecture scenario we had recently and how we were able to utilise NServiceBus to help us address this problem. Scenario Cognos is a reporting system used by one of my clients. A while back we developed a web service façade to allow line of business applications to be able to access reports from Cognos to support their various functions. The service was intended to provide access to reports which were quick running reports or pre-generated reports which could be accessed real-time on demand. One of the key aims of the web service was to provide a simple generic interface to allow applications to get any report without needing to worry about the complex .net SDK for Cognos. The web service also supported multi-hop kerberos delegation so that report data could be accesses under the context of the end user. This service was working well for a period of time. The Problem The problem we encountered was that reports were now also required to be available to batch processes. The original design was optimised for low latency so users would enjoy a positive experience, however when the batch processes started to request 250+ concurrent reports over an extended period of time you can begin to imagine the sorts of problems that come into play. The key problems this new scenario caused are: Users may be affected and the latency of on demand reports was significantly slower The Cognos infrastructure was not scaled sufficiently to be able to cope with these long peaks of load From a cost perspective it just isn't feasible to scale the Cognos infrastructure to be able to handle the load when it is only for a couple of hour window each night. We really needed to introduce a second pattern for accessing this service which would support high through-put scenarios. We also had little control over the batch process in terms of being able to throttle its load. We could however make some changes to the way it accessed the reports. The Approach My idea was to introduce a throttling mechanism between the Web Service Façade and Cognos. This would allow the batch processes to push reports requests hard at the web service which we were confident the web service can handle. The web service would then queue these requests and process them behind the scenes and make a call back to the batch application to provide the report once it had been accessed. In terms of technology we had some limitations because we were not able to use WCF or IIS7 where the MSMQ-Activated WCF services could have helped, but we did have MSMQ as an option and I thought NServiceBus could do just the job to help us here. The flow of how this would work was as follows: The batch applications would send a request for a report to the web service The web service uses NServiceBus to send the message to a Queue The NServiceBus Generic Host is running as a windows service with a message handler which subscribes to these messages The message handler gets the message, accesses the report from Cognos The message handler calls back to the original batch application, this is decoupled because the calling application provides a call back url The report gets into the batch application and is processed as normal This approach looks something like the below diagram: The key points are an application wanting to take advantage of the batch driven reports needs to do the following: Implement our call back contract Make a call to the service providing a call back url Provide a correlation ID so it knows how to tie each response back to its request What does NServiceBus offer in this solution So this scenario is not the typical messaging service bus type of solution people implement with NServiceBus, but it did offer the following: Simplified interaction with MSMQ Offered the ability to configure the number of processes working through the queue so we could find a balance between load on Cognos versus the applications end to end processing time NServiceBus offers retries and a way to manage failed messages NServiceBus offers a high availability setup The simple thing is that NServiceBus gave us the platform to build the solution on. We just implemented a message handler which functionally processed a message and we could rely on NServiceBus to do all of the hard work around managing the queues and all of the lower level things that would have took ages to write to any kind of robust level. Conclusion With this approach we were able to deal with a fairly significant performance issue with out too much rework. Hopefully this write up gives people some insight into ideas on how to leverage the excellent NServiceBus framework to help solve integration and high through-put scenarios.

• Amazon Product Advertising API SOAP Namespace Changes

  - by Rick Strahl

  About two months ago (twowards the end of February 2012 I think) Amazon decided to change the namespace of the Product Advertising API. The error that would come up was: <ItemSearchResponse > was not expected. If you've used the Amazon Product Advertising API you probably know that Amazon has made it a habit to break the services every few years or so and I guess last month was about the time for another one. Basically the service namespace of the document has been changed and responses from the service just failed outright even though the rest of the schema looks fine. Now I looked around for a while trying to find a recent update to the Product Advertising API - something semi-official looking but everything is dated around 2009. Really??? And it's not just .NET - the newest thing on the sample/APIs is dated early 2011 and a handful of 2010 samples. There are newer full APIs for the 'cloud' offerings, but the Product Advertising API apparently isn't part of that. After searching for quite a bit trying to trace this down myself and trying some of the newer samples (which also failed) I found an obscure forum post that describes the solution of getting past the namespace issue. FWIW, I've been using an old version of the Product Advertising API using the old Microsoft WSE3 services (pre-WCF), which provides some of the WS* security features required by the Amazon service. The fix for this code is to explicitly override the namespace declaration on each of the imported service method signatures. The old service namespace (at least on my build) was: http://webservices.amazon.com/AWSECommerceService/2009-03-31 and it should be changed to: http://webservices.amazon.com/AWSECommerceService/2011-08-01 Change it on the class header:[Microsoft.Web.Services3.Messaging.SoapService("http://webservices.amazon.com/AWSECommerceService/2011-08-01")] [System.Xml.Serialization.XmlIncludeAttribute(typeof(Property[]))] [System.Xml.Serialization.XmlIncludeAttribute(typeof(BrowseNode[]))] [System.Xml.Serialization.XmlIncludeAttribute(typeof(TransactionItem[]))] public partial class AWSECommerceService : Microsoft.Web.Services3.Messaging.SoapClient { and on all method signatures:[Microsoft.Web.Services3.Messaging.SoapMethodAttribute("http://soap.amazon.com/ItemSearch")] [return: System.Xml.Serialization.XmlElementAttribute("ItemSearchResponse", Namespace="http://webservices.amazon.com/AWSECommerceService/2011-08-01")] public ItemSearchResponse ItemSearch(ItemSearch ItemSearch1) { Microsoft.Web.Services3.SoapEnvelope results = base.SendRequestResponse("ItemSearch", ItemSearch1); return ((ItemSearchResponse)(results.GetBodyObject(typeof(ItemSearchResponse), this.SoapServiceAttribute.TargetNamespace))); } It's easy to do with a Search and Replace on the above strings. Amazon Services <rant> FWIW, I've not been impressed by Amazon's service offerings. While the services work well, their documentation and tool support is absolutely horrendous. I was recently working with a customer on an old AWS application and their old API had been completely removed with a new API that wasn't even a close match. One old API call resulted in requiring three different APIs to perform the same functionality. We had to re-write the entire piece from scratch essentially. The documentation was downright wrong, and incomplete and so scattered it was next to impossible to follow. The examples weren't examples at all - they're mockups of real service calls with fake data that didn't even provide everything that was required to make same service calls work. Additionally there appears to be just about no public support from Amazon, only peer support which is sparse at best - and getting a hold of somebody at Amazon, even for pay seems to be mythical task. It's a terrible business model they have going. I can't see why anybody would put themselves through this sort of customer and development experience. Sad really, but an experience we see more and more these days. Nobody puts in the time to document anything anymore, leaving it to devs to figure this stuff out over and over again… </rant>© Rick Strahl, West Wind Technologies, 2005-2012Posted in CSharp  Web Services   Tweet !function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src="//platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs"); (function() { var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true; po.src = 'https://apis.google.com/js/plusone.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s); })();

• Do We Indeed Have a Future? George Takei on Star Wars.

  - by Bil Simser

  George Takei (rhymes with Okay), probably best known for playing Hikaru Sulu on the original Star Trek, has always had deep concerns for the present and the future. Whether on Earth or among the stars, he has the welfare of humanity very much at heart. I was digging through my old copies of Famous Monsters of Filmland, a great publication on monster and films that I grew up with, and came across this. This was his reaction to STAR WARS from issue 139 of Famous Monsters of Filmland and was written June 6, 1977. It is reprinted here without permission but I hope since the message is still valid to this day and has never been reprinted anywhere, nobody will mind me sharing it. STAR WARS is the most pre-posterously diverting galactic escape and at the same time the most hideously credible portent of the future yet.While I thrilled to the exploits that reminded me of the heroics of Errol Flynn as Robin Hood, Burt Lancaster as the Crimson Pirate and Buster Crabbe as Flash Gordon, I was at the same time aghast at the phantasmagoric violence technology can place at our disposal. STAR WARS raised in my mind the question - do we indeed have a future?It seems to me what George Lucas has done is to masterfully guide us on a journey through space and time and bring us back face to face with today's reality. STAR WARS is more than science fiction, I think it is science fictitious reality.Just yesterday, June 7, 1977, I read that the United States will embark on the production of a neutron bomb - a bomb that will kill people on a gigantic scale but will not destroy buildings. A few days before that, I read that the Pentagon is fearful that the Soviets may have developed a warhead that could neutralize ours that have a capacity for that irrational concept overkill to the nth power. Already, it seems we have the technology to realize the awesome special effects simulations that we saw in the film.The political scene of STAR WARS is that of government by force and power, of revolutions based on some unfathomable grievance, survival through a combination of cunning and luck and success by the harnessing of technology -  a picture not very much at variance from the political headlines that we read today.And most of all, look at the people; both the heroes in the film and the reaction of the audience. First, the heroes; Luke Skywalker is a pretty but easily led youth. Without any real philosophy to guide him, he easily falls under the influence of a mystical old man believed previously to be an eccentric hermit. Recognize a 1960's hippie or a 1970's moonie? Han Solo has a philosophy coupled with courage and skill. His philosophy is money. His proficiency comes for a price - the highest. Solo is a thoroughly avaricious mercenary. And the Princess, a decisive, strong, self-confident and chilly woman. The audience cheered when she wielded a gun. In all three, I missed qualities that could be called humane - love, kindness, yes, I missed sensuality. I also missed a sense of ideals and faith. In this regard the machines seemed more human. They demonstrated real affection for each other and an occasional poutiness. They exhibited a sense of fidelity and constancy. The machines were humanized and the humans conversely seemed mechanical.As a member of the audience, I was swept up by the sheer romantic escapsim of it all. The deering-dos, the rope swing escape across the pit, the ray gun battles and especially the swash buckle with the ray swords. Great fun!But I just hope that we weren't too intoxicated by the escapism to be able to focus on the recognizable. I hope the beauty of the effects didn't narcotize our sensitivity to violence. I hope the people see through the fantastically well done futuristic mirrors to the disquieting reflection of our own society. I hope they enjoy STAR WARS without being "purely entertained".

• Auto-cancel reason not found (6, 13906)

  - by Rajesh Sharma

  There are many errors in the application which are never invoked because of appropriate application configuration done at the time of implementation by the solution architects. So typically, as an application end user you would never stumble upon such errors. But what if the application administrator inadvertently changes the configuration/setup in the development, test, QA, or production environment? This is the time when you as an end user are introduced to a brand-new error for which you may not have a clue or understanding to what it means and neither the access/privilege to rectify it.    In this post we'll focus on one such error '6, 13906 - Auto-cancel reason not found'.   You get this error if you have not defined a Bill (Segment) Cancel Reason (Admin Menu, B, Bill Cancel Reason) code with System Default value of Turn off auto-cancel.   Consider a scenario when you are about to final bill an 'Account' for which the bill period's cut-off date you selected is falling on or after the Service Agreement's (SA) end/stop date (basically SA is Stopped with a date earlier than it was billed previously). And for the same 'Account' either: Bill segments exists that end after the SA's end date OR Non-closing bill segments exists that end on the SA's end date (OR closing bill segments that do not end on SA's end date or do not exist at all - remember closing/final bill segment is generated if the SA is in Stopped status).   CC&B detects such scenario and attempts to cancel all such violating bill segments automatically, but NOT if you are generating the bill Online. If online, the system assumes that you know what you are doing, and prompts you with error 2, 13716 - Bill segments that violate the SA (%1) End Date (%2) exist to take necessary action.   If in batch, system automatically cancels these kinds of bill segment(s).   Since this happens in the background, you have to define within the application which System Default Bill (Segment) cancellation reason code identified as Turn off auto-cancel, should be used by the process when it attempts to cancel any such violating bill segments (You already know that you cannot cancel a bill segment without giving a reason for cancellation).   So what exactly happens during batch billing?   Bill Segment generation routine at first determines billing eligibility of the service agreement being billed. One of the billing eligibility criteria is to check the SA's previous bill segments which have end dates greater than the current cut-off date/end date. Technically, the routine retrieves a count of such violating bill segments.     SELECT COUNT (*) FROM CI_BSEG WHERE SA_ID = :SA-ID AND BSEG_STAT_FLG = '50' -- Frozen AND END_DT IS NOT NULL AND (END_DT > '03-JUN-2010' -- Bill segment greater than SA's End Date OR OR (END_DT = '03-JUN-2010' AND CLOSING_BSEG_SW = 'N')) -- Non-closing bill segment ending on SA's end date   If the count is greater than zero, Bill segment generation routine executes another program to auto-cancel such bill segments. Auto-cancel program retrieves the 'Bill Cancel Reason' code which is identified as Turn off auto-cancel. Retrieved cancel reason code is then placed on the bill segments that are being cancelled automatically.   During this process if the routine fails to determine the bill cancel reason code having System Default Turn off auto-cancel because it was not been configured, you get a bill exception 6, 13906 - Auto-cancel reason not found.   Also note that duplicate or multiple System Default codes identified as Turn off auto-cancel are not allowed. CC&B would complain with an error 2, 54201.   Duplicate validation/check is also performed within Auto-cancel routine, if suppose for test purposes you executed a DML statement updating CI_BILL_CAN_RSN.BSCAN_SYS_DFLT_FLG with a value 'T'.

• Rotate a Video 90 degrees with VLC or Windows Live Movie Maker

  - by DigitalGeekery

  Have you ever captured video with your cell phone or camcorder only to discover when you play it back on your computer that the video is rotated 90 degrees? Or maybe you shot it that way on purpose because you preferred portrait style to a landscape view? Before you go straining your neck or flipping your monitor on it’s side to watch your video, we’ll show you a few easier methods. If you simply want to rotate the video while you watch it, we’ll show you how to accomplish that with VLC Media Player. If you want to convert the video so it is rotated permanently, we’ll show you how to do that with Windows Live Movie Maker and output your video as a WMV file. Rotate and Watch a Video in VLC Download, install, and run VLC Media Player. (See download link below)   Open your video file by going to Media  > Open File… and browsing for your file. Or, by just dragging and dropping your video onto the VLC player.   Choose Tools from the Menu bar and select Effects and Filters. On the Video Effects tab, tick the Transform checkbox and choose your degrees of rotation. The video is rotated counter-clockwise, so to rotate clockwise 90 degrees you’ll want to choose Rotate by 270 degrees.   Now you can enjoy your video the way it was intended to be viewed. Rotate and Convert the Video with Windows Live Movie Maker Starting with Windows 7, Windows Movie Maker no longer comes pre-installed with the OS. It’s now part of the Windows Live suite that is available as a separate, free download for Windows 7 and Vista. (Windows XP is not supported) You can find the link to our detailed instruction on how to install Windows Live at the end of the article. To add your video files to Windows Movie Maker, click on Add videos and photos on the Home tab, or drag and drop the video into the blank area on the right side of the application. Next, you’ll need to rotate the video. Staying on the Home tab, click on the Rotate right 90° or Rotate left 90°.   You’ll see your video is now oriented properly on the left.   To save and convert your video to WMV format, click the Movie Maker tab just to the left of the Home tab. Hover your cursor over Save movie, and then select your output settings. You also have the option to burn directly to DVD. Browse for a location to save it and rename the output file if you’d like. Click Save. You’ll be notified when the file is complete. Now you’ll have your video properly oriented in WMV file format.   These are two rather easy ways to accomplish rotating your video. Unfortunately, Windows Live Movie Maker doesn’t give you a lot of  options for output. If you want to output to a file, your only choice is WMV format or DVD. However, previous versions will also allow you to export to AVI. How-To Geek’s Install Windows Live Essentials In Windows 7 Article.

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

  - by Mysticgeek

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

• Dynamic Class Inheritance For PHP

  - by VirtuosiMedia

  I have a situation where I think I might need dynamic class inheritance in PHP 5.3, but the idea doesn't sit well and I'm looking for a different design pattern to solve my problem if it's possible. Use Case I have a set of DB abstraction layer classes that dynamically compiles SQL queries, with one DAL class for each DB type (MySQL, MsSQL, Oracle, etc.). Each table in the database has its own class that extends the appropriate DAL class. The idea is that you interact with the table classes, but never directly use the DAL class. If you want to support a different DB type for your app, you don't need to rewrite any queries or even any code, you simply change a setting that swaps one DAL class out for another...and that's it. To give you a better idea of how this is used, you can take a look at the DAL class, the table classes, and how they are used on this StackExchange Code Review page. To really understand what I'm trying to do, please take a look at my implementation first before suggesting a solution. Issues The strategy that I had used previously was to have all of the DAL classes share the same class name. This eliminated autoloading, so I had to manually load the appropriate DAL class in a switch statement. However, this approach presents some problems for testing and documentation purposes, so I'd like to find a different way to solve the problem of loading the correct DAL class more elegantly. Update to clarify the issue The problem basically boils down to inconsistencies in the class name (pre-PHP 5.3) or class namespace (PHP 5.3) and its location in the directory structure. At this point, all of my DAL classes have the same name, DBObject, but reside in different folders, MySQL, Oracle, etc. My table classes all extend DBObject, but which DBObject they extend varies depending on which one has been loaded. Basically, I'm trying to have my cake and eat it too. The table classes act as a stable API and extend a dynamic backend, the DAL (DBObject) classes. It works great, but I outsmarted myself and because of the inconsistencies with the class names and their locations, I can't autoload the DBObject, which makes running unit tests and generating API docs impossible for the DBObject classes because the tests and docs rely on auto-loading. Just loading the appropriate DBObject into memory using a factory method won't work because there will be times when I need to load multiple DBObjects for testing. Because the classes currently share a name, this causes a class is already defined error. I can make exceptions for the DBObjects in my test code, obviously, but I'm looking for something a little less hacky as there may future instances where something similar would need to be done. Solutions? Worst case scenario, I can continue my current strategy, but I don't like it very much, especially as I'll soon be converting my code to PHP 5.3. I suspect that I can use some sort of dynamic inheritance via either namespaces (preferred) or a dynamic class extension, but I haven't been able to find good examples of this implemented in the wild. In your answers, please suggest either an alternate pattern that would work for this use case or an example of dynamic inheritance done right. Please assume PHP 5.3 with namespaced code. Any code examples are greatly encouraged. The preferred constraints for the solution are: DAL class can be autoloaded. DAL classes don't share the same exact same namespace, but share the same class name. As an example, I would prefer to use classes named DbObject that use namespaces like Vm\Db\MySql and Vm\Db\Oracle. Table classes don't have to be rewritten with a change in DB type. The appropriate DB type is determined via a single setting only. That setting is the only thing that should need to change to interchange DB types. Ideally, the setting check should occur only once per page load, but I'm flexible on that.

• SQL SERVER – MSQL_XP – Wait Type – Day 20 of 28

  - by pinaldave

  In this blog post, I am going to discuss something from my field experience. While consultation, I have seen various wait typed, but one of my customers who has been using SQL Server for all his operations had an interesting issue with a particular wait type. Our customer had more than 100+ SQL Server instances running and the whole server had MSSQL_XP wait type as the most number of wait types. While running sp_who2 and other diagnosis queries, I could not immediately figure out what the issue was because the query with that kind of wait type was nowhere to be found. After a day of research, I was relieved that the solution was very easy to figure out. Let us continue discussing this wait type. From Book On-Line: ?MSQL_XP occurs when a task is waiting for an extended stored procedure to end. SQL Server uses this wait state to detect potential MARS application deadlocks. The wait stops when the extended stored procedure call ends. MSQL_XP Explanation: This wait type is created because of the extended stored procedure. Extended Stored Procedures are executed within SQL Server; however, SQL Server has no control over them. Unless you know what the code for the extended stored procedure is and what it is doing, it is impossible to understand why this wait type is coming up. Reducing MSQL_XP wait: As discussed, it is hard to understand the Extended Stored Procedure if the code for it is not available. In the scenario described at the beginning of this post, our client was using third-party backup tool. The third-party backup tool was using Extended Stored Procedure. After we learned that this wait type was coming from the extended stored procedure of the backup tool they were using, we contacted the tech team of its vendor. The vendor admitted that the code was not optimal at some places, and within that day they had provided the patch. Once the updated version was installed, the issue on this wait type disappeared. As viewed in the wait statistics of all the 100+ SQL Server, there was no more MSSQL_XP wait type found. In simpler terms, you must first identify which Extended Stored Procedure is creating the wait type of MSSQL_XP and see if you can get in touch with the creator of the SP so you can help them optimize the code. If you have encountered this MSSQL_XP wait type, I encourage all of you to write how you managed it. Please do not mention the name of the vendor in your comment as I will not approve it. The focus of this blog post is to understand the wait types; not talk about others. Read all the post in the Wait Types and Queue series. Note: The information presented here is from my experience and there is no way that I claim it to be accurate. I suggest reading Book OnLine for further clarification. All the discussion of Wait Stats in this blog is generic and varies from system to system. It is recommended that you test this on a development server before implementing it to a production server.
