  - by John Alexander

  From a message from Brian Keller: “Back in December we posted a set of virtual machines pre-configured with Visual Studio 2010 Beta 2, Visual Studio Team Foundation Server 2010 Beta 2, and 7 hands-on-labs. I am pleased to announce that today we have shipped an updated virtual machine using the Visual Studio 2010 Release Candidate bits, a brand new sample application, and 9 hands-on-labs. This VM is customer-ready and includes everything you need to learn and/or deliver demonstrations of many of my favorite application lifecycle management (ALM) capabilities in Visual Studio 2010. This VM is available in the virtualization platform of your choice (Hyper-V, Virtual PC 2007 SP1, and Windows [7] Virtual PC). Hyper-V is highly recommended because of the performance benefits and snapshotting capabilities. Tailspin Toys The sample application we are using in this virtual machine is a simple ASP.NET MVC 2 storefront called Tailspin Toys. Tailspin Toys sells model airplanes and relies on the application lifecycle management capabilities of Visual Studio 2010 to help them build, test, and maintain their storefront. Major kudos go to Dan Massey for building out this great application for us. Hands-on-Labs / Demo Scripts The 9 hands-on-labs / demo scripts which accompany this virtual machine cover several of the core capabilities of conducting application lifecycle management with Visual Studio 2010. Each document can be used by an individual in a hands-on-lab capacity, to learn how to perform a given set of tasks, or used by a presenter to deliver a demonstration or classroom-style training. Unlike the beta 2 release, 100% of these labs target Tailspin Toys to help ensure a consistent storytelling experience.

• Requirement refinement between two levels of specification

  - by user107149

  I am currently working on the definition of the documentation architecture of a system, from customers needs to software/hardware requirements. I encounter a big problem with the level of refinement of requirements. The classic architecture is : PTS -- SSS -- SSDD -- SRS/HRS with PTS : Purshaser Technical Specification SSS : Supplier System Specification SSDD : System Segment Design Description SRS / HRS : Software / Hardware Requirement Specification. Requirements from PTS are reworked in SSS, this document only expressed the needs (no design requirements are defined at this level). Then, the system design is described in SSDD : we allocate requirements from the SSS to functions from the design and functions are then allocated to component (Software or hardware) (we are still at the SSDD level). Finally, for each component, we write one SRS or one HRS. Requirements in SRS or HRS are refinement of requirements from SSS (and traceability matrix are made between these two levels). My problem is the following one : Our system is a complex one, and some of the requirements in the SSS needs to be refined twice to be at the right level in the SRS (means that software people can understand the requirement to make their coding). But, with this document architecture, I can only refine once the requirements from the SSS. The second problem is that only a part of the requirements from the SSS needs to be refined twice. The other part only need one refinement. On the picture below, the green boxes are requirements at the right level for SRS or HRS. And purple boxes are intermediate requirements which can not be included in SSS since they are design requirements. Where can I put these purple requirements ?? Is there someone who has already encountered this problem ? Should I write two documents at SRS level ? Should I include intermediate requirements in SSDD ? Should I includes the two refinement levels (purple and green) in the same SRS document (not sure that's possible since a SRS is only for one component) ??? Thanks for your help and expertise ;-)

• Investigation: Can different combinations of components effect Dataflow performance?

  - by jamiet

  Introduction The Dataflow task is one of the core components (if not the core component) of SQL Server Integration Services (SSIS) and often the most misunderstood. This is not surprising, its an incredibly complicated beast and we’re abstracted away from that complexity via some boxes that go yellow red or green and that have some lines drawn between them. Example dataflow In this blog post I intend to look under that facade and get into some of the nuts and bolts of the Dataflow Task by investigating how the decisions we make when building our packages can affect performance. I will do this by comparing the performance of three dataflows that all have the same input, all produce the same output, but which all operate slightly differently by way of having different transformation components. I also want to use this blog post to challenge a common held opinion that I see perpetuated over and over again on the SSIS forum. That is, that people assume adding components to a dataflow will be detrimental to overall performance. Its not surprising that people think this –it is intuitive to think that more components means more work- however this is not a view that I share. I have always been of the opinion that there are many factors affecting dataflow duration and the number of components is actually one of the less important ones; having said that I have never proven that assertion and that is one reason for this investigation. I have actually seen evidence that some people think dataflow duration is simply a function of number of rows and number of components. I’ll happily call that one out as a myth even without any investigation!  The Setup I have a 2GB datafile which is a list of 4731904 (~4.7million) customer records with various attributes against them and it contains 2 columns that I am going to use for categorisation: [YearlyIncome] [BirthDate] The data file is a SSIS raw format file which I chose to use because it is the quickest way of getting data into a dataflow and given that I am testing the transformations, not the source or destination adapters, I want to minimise external influences as much as possible. In the test I will split the customers according to month of birth (12 of those) and whether or not their yearly income is above or below 50000 (2 of those); in other words I will be splitting them into 24 discrete categories and in order to do it I shall be using different combinations of SSIS’ Conditional Split and Derived Column transformation components. The 24 datapaths that occur will each input to a rowcount component, again because this is the least resource intensive means of terminating a datapath. The test is being carried out on a Dell XPS Studio laptop with a quad core (8 logical Procs) Intel Core i7 at 1.73GHz and Samsung SSD hard drive. Its running SQL Server 2008 R2 on Windows 7. The Variables Here are the three combinations of components that I am going to test:     One Conditional Split - A single Conditional Split component CSPL Split by Month of Birth and income category that will use expressions on [YearlyIncome] & [BirthDate] to send each row to one of 24 outputs. This next screenshot displays the expression logic in use: Derived Column & Conditional Split - A Derived Column component DER Income Category that adds a new column [IncomeCategory] which will contain one of two possible text values {“LessThan50000”,”GreaterThan50000”} and uses [YearlyIncome] to determine which value each row should get. A Conditional Split component CSPL Split by Month of Birth and Income Category then uses that new column in conjunction with [BirthDate] to determine which of the same 24 outputs to send each row to. Put more simply, I am separating the Conditional Split of #1 into a Derived Column and a Conditional Split. The next screenshots display the expression logic in use: DER Income Category         CSPL Split by Month of Birth and Income Category       Three Conditional Splits - A Conditional Split component that produces two outputs based on [YearlyIncome], one for each Income Category. Each of those outputs will go to a further Conditional Split that splits the input into 12 outputs, one for each month of birth (identical logic in each). In this case then I am separating the single Conditional Split of #1 into three Conditional Split components. The next screenshots display the expression logic in use: CSPL Split by Income Category         CSPL Split by Month of Birth 1& 2       Each of these combinations will provide an input to one of the 24 rowcount components, just the same as before. For illustration here is a screenshot of the dataflow containing three Conditional Split components: As you can these dataflows have a fair bit of work to do and remember that they’re doing that work for 4.7million rows. I will execute each dataflow 10 times and use the average for comparison. I foresee three possible outcomes: The dataflow containing just one Conditional Split (i.e. #1) will be quicker There is no significant difference between any of them One of the two dataflows containing multiple transformation components will be quicker Regardless of which of those outcomes come to pass we will have learnt something and that makes this an interesting test to carry out. Note that I will be executing the dataflows using dtexec.exe rather than hitting F5 within BIDS. The Results and Analysis The table below shows all of the executions, 10 for each dataflow. It also shows the average for each along with a standard deviation. All durations are in seconds. I’m pasting a screenshot because I frankly can’t be bothered with the faffing about needed to make a presentable HTML table. It is plain to see from the average that the dataflow containing three conditional splits is significantly faster, the other two taking 43% and 52% longer respectively. This seems strange though, right? Why does the dataflow containing the most components outperform the other two by such a big margin? The answer is actually quite logical when you put some thought into it and I’ll explain that below. Before progressing, a side note. The standard deviation for the “Three Conditional Splits” dataflow is orders of magnitude smaller – indicating that performance for this dataflow can be predicted with much greater confidence too. The Explanation I refer you to the screenshot above that shows how CSPL Split by Month of Birth and salary category in the first dataflow is setup. Observe that there is a case for each combination of Month Of Date and Income Category – 24 in total. These expressions get evaluated in the order that they appear and hence if we assume that Month of Date and Income Category are uniformly distributed in the dataset we can deduce that the expected number of expression evaluations for each row is 12.5 i.e. 1 (the minimum) + 24 (the maximum) divided by 2 = 12.5. Now take a look at the screenshots for the second dataflow. We are doing one expression evaluation in DER Income Category and we have the same 24 cases in CSPL Split by Month of Birth and Income Category as we had before, only the expression differs slightly. In this case then we have 1 + 12.5 = 13.5 expected evaluations for each row – that would account for the slightly longer average execution time for this dataflow. Now onto the third dataflow, the quick one. CSPL Split by Income Category does a maximum of 2 expression evaluations thus the expected number of evaluations per row is 1.5. CSPL Split by Month of Birth 1 & CSPL Split by Month of Birth 2 both have less work to do than the previous Conditional Split components because they only have 12 cases to test for thus the expected number of expression evaluations is 6.5 There are two of them so total expected number of expression evaluations for this dataflow is 6.5 + 6.5 + 1.5 = 14.5. 14.5 is still more than 12.5 & 13.5 though so why is the third dataflow so much quicker? Simple, the conditional expressions in the first two dataflows have two boolean predicates to evaluate – one for Income Category and one for Month of Birth; the expressions in the Conditional Split in the third dataflow however only have one predicate thus they are doing a lot less work. To sum up, the difference in execution times can be attributed to the difference between: MONTH(BirthDate) == 1 && YearlyIncome <= 50000 and MONTH(BirthDate) == 1 In the first two dataflows YearlyIncome <= 50000 gets evaluated an average of 12.5 times for every row whereas in the third dataflow it is evaluated once and once only. Multiply those 11.5 extra operations by 4.7million rows and you get a significant amount of extra CPU cycles – that’s where our duration difference comes from. The Wrap-up The obvious point here is that adding new components to a dataflow isn’t necessarily going to make it go any slower, moreover you may be able to achieve significant improvements by splitting logic over multiple components rather than one. Performance tuning is all about reducing the amount of work that needs to be done and that doesn’t necessarily mean use less components, indeed sometimes you may be able to reduce workload in ways that aren’t immediately obvious as I think I have proven here. Of course there are many variables in play here and your mileage will most definitely vary. I encourage you to download the package and see if you get similar results – let me know in the comments. The package contains all three dataflows plus a fourth dataflow that will create the 2GB raw file for you (you will also need the [AdventureWorksDW2008] sample database from which to source the data); simply disable all dataflows except the one you want to test before executing the package and remember, execute using dtexec, not within BIDS. If you want to explore dataflow performance tuning in more detail then here are some links you might want to check out: Inequality joins, Asynchronous transformations and Lookups Destination Adapter Comparison Don’t turn the dataflow into a cursor SSIS Dataflow – Designing for performance (webinar) Any comments? Let me know! @Jamiet

• Instructor Insight: Using the Container Database in Oracle Database 12 c

  - by Breanne Cooley

  The first time I examined the Oracle Database 12c architecture, I wasn’t quite sure what I thought about the Container Database (CDB). In the current release of the Oracle RDBMS, the administrator now has a choice of whether or not to employ a CDB. Bundling Databases Inside One Container In today’s IT industry, consolidation is a common challenge. With potentially hundreds of databases to manage and maintain, an administrator will require a great deal of time and resources to upgrade and patch software. Why not consider deploying a container database to streamline this activity? By “bundling” several databases together inside one container, in the form of a pluggable database, we can save on overhead process resources and CPU time. Furthermore, we can reduce the human effort required for periodically patching and maintaining the software. Minimizing Storage Most IT professionals understand the concept of storage, as in solid state or non-rotating. Let’s take one-to-many databases and “plug” them into ONE designated container database. We can minimize many redundant pieces that would otherwise require separate storage and architecture, as was the case in previous releases of the Oracle RDBMS. The data dictionary can be housed and shared in one CDB, with individual metadata content for each pluggable database. We also won’t need as many background processes either, thus reducing the overhead cost of the CPU resource. Improve Security Levels within Each Pluggable Database  We can now segregate the CDB-administrator role from that of the pluggable-database administrator as well, achieving improved security levels within each pluggable database and within the CDB. And if the administrator chooses to use the non-CDB architecture, everything is backwards compatible, too.  The bottom line: it's a good idea to at least consider using a CDB. -Christopher Andrews, Senior Principal Instructor, Oracle University

• JavaServer Faces 2.0 for the Cloud

  - by Janice J. Heiss

  A new article now up on otn/java by Deepak Vohra titled “JSF 2.0 for the Cloud, Part One,” shows how JavaServer Faces 2.0 provides features ideally suited for the virtualized computing resources of the cloud. The article focuses on @ManagedBean annotation, implicit navigation, and resource handling. Vohra illustrates how the container-based model found in Java EE 7, which allows portable applications to target single machines as well as large clusters, is well suited to the cloud architecture. From the article-- “Cloud services might not have been a factor when JavaServer Faces 2.0 (JSF 2.0) was developed, but JSF 2.0 provides features ideally suited for the cloud, for example:•    The path-based resource handling in JSF 2.0 makes handling virtualized resources much easier and provides scalability with composite components.•    REST-style GET requests and bookmarkable URLs in JSF 2.0 support the cloud architecture. Representational State Transfer (REST) software architecture is based on transferring the representation of resources identified by URIs. A RESTful resource or service is made available as a URI path. Resources can be accessed in various formats, such as XML, HTML, plain text, PDF, JPEG, and JSON, among others. REST offers the advantages of being simple, lightweight, and fast.•    Ajax support in JSF 2.0 is integrable with Software as a Service (SaaS) by providing interactive browser-based Web applications.” In Part Two of the series, Vohra will examine features such as Ajax support, view parameters, preemptive navigation, event handling, and bookmarkable URLs.Have a look at the article here.

• How important do you find exception safety to be in your C++ code?

  - by Kai

  Every time I consider making my code strongly exception safe, I justify not doing it because it would be so time consuming. Consider this relatively simple snippet: Level::Entity* entity = new Level::Entity(); entity->id = GetNextId(); entity->AddComponent(new Component::Position(x, y)); entity->AddComponent(new Component::Movement()); entity->AddComponent(new Component::Render()); allEntities.push_back(entity); // std::vector entityById[entity->id] = entity; // std::map return entity; To implement a basic exception guarantee, I could use a scoped pointer on the new calls. This would prevent memory leaks if any of the calls were to throw an exception. However, let's say I want to implement a strong exception guarantee. At the least, I would need to implement a shared pointer for my containers (I'm not using Boost), a nothrow Entity::Swap for adding the components atomically, and some sort of idiom for atomically adding to both the Vector and Map. Not only would these be time consuming to implement, but they would be expensive since it involves a lot more copying than the exception unsafe solution. Ultimately, it feels to me like that time spent doing all of that wouldn't be justified just so that the a simple CreateEntity function is strongly exception safe. I probably just want the game to display an error and close at that point anyway. How far do you take this in your own game projects? Is it generally acceptable to write exception unsafe code for a program that can just crash when there is an exception?

I think that problem will be in architecture becase: liblwjgl.so: /home/zrebec/.minecraft/bin/natives/liblwjgl.so: wrong ELF class: ELFCLASS32 (Possible cause: architecture word width mismatch) Any idea please? I know, maybe this one is off topic because maybe its not Ubuntu problem maybe but in 64-bit works all perfectly and I think that accepted answer can help to many users and can make better playing games under linux. Really. Thank you very much for any idea.

• Migrating BizTalk 2006 R2 to BizTalk 2010 XLANGs Issue

  - by SURESH GIRIRAJAN

  When we migrate some BizTalk apps from BizTalk 2006 R2 to BizTalk 2010, and we ran into issue when a .net component called inside the orchestration. In the .net component we are trying to retrieve some promoted property and we also checked in the BizTalk group hub to validate it was promoted, no issues there.  Only when we try to access the data into the .net component we had issue. We just moved all the assembly what we had in BizTalk 2006 R2 to BizTalk 2010, didn’t recompile anything in BizTalk 2010 environment. But looking further there is couple of new namespace added to the Microsoft.XLANGs… in BizTalk 2010 compared to BizTalk 2006 R2 caused the issue. So all we did to fix the issue is recompile the project in 2010 environment and it worked fine. So it looks like some backward compatibility issue.  public static void Load(XLANGMessage msg) {  try  {      // get the process id from context.       object ctxVal = msg.GetPropertyValue(typeof(ProcessID)); … } BizTalk 2010: Error Message in the event viewer:  The service instance will remain suspended until administratively resumed or terminated. If resumed the instance will continue from its last persisted state and may re-throw the same unexpected exception.

• The current state of a MERGE Destination for SSIS

  - by jamiet

  Hugo Tap asked me on Twitter earlier today whether or not there existed a SSIS Dataflow Destination component that enabled one to MERGE data into a table rather than INSERT it. Its a common request so I thought it might be useful to summarise the current state of play as regards a MERGE destination for SSIS. Firstly, there is no MERGE destination component in the box; that is, when you install SSIS no MERGE Destination will be available. That being said the SSIS team have made available a MERGE destination component via Codeplex which you can get from http://sqlsrvintegrationsrv.codeplex.com/releases/view/19048. I have never used it so cannot vouch for its usefulness although judging by some of the reviews you might not want to set your expectations too high. Your mileage may vary.   In the past it has occurred to me that a built-in way to provide MERGE from the SSIS pipeline would be highly valuable. I assume that this would have to be provided by the database into which you were merging hence in March 2010 I submitted the following two requests to Connect: BULK MERGE (111 votes at the time of writing) [SSIS] BULK MERGE Destination (15 votes) If you think these would be useful feel free to vote them up and add a comment. Lastly, this one is nothing to do with SSIS but if you want to perform a minimally logged MERGE using T-SQL Sunil Agarwal has explained how at Minimal logging and MERGE statement. @Jamiet

• Gotcha when using JavaScript in ADF Regions

  - by Frank Nimphius

  You use the ADF Faces af:resource tag to add or reference JavaScript on a page. However, adding the af:resource tag to a page fragment my not produce the desired result if the script is added as shown below <?xml version='1.0' encoding='UTF-8'?> <jsp:root xmlns:jsp="http://java.sun.com/JSP/Page" version="2.1" xmlns:af="http://xmlns.oracle.com/adf/faces/rich"> <af:resource type="javascript">   function yourMethod(evt){ ... } </af:resource> Adding scripts to a page fragment like this will see the script added for the first page fragment loaded by an ADF region but not for any subsequent fragment navigated to within the context of task flow navigation. The cause of this problem is caching as the af:resource tag is a JSP element and not a lazy loaded JSF component, which makes it a candidate for caching. To solve the problem, move the af:resource tag into a container component like af:panelFormLayout so the script is added when the component is instantiated and added to the page.  <?xml version='1.0' encoding='UTF-8'?> <jsp:root xmlns:jsp="http://java.sun.com/JSP/Page" version="2.1" xmlns:af="http://xmlns.oracle.com/adf/faces/rich"> <af:panelFormLayout> <af:resource type="javascript">   function yourMethod(evt){ ... } </af:resource> </af:panelFormLayout> Magically this then works and prevents browser caching of the script when using page fragments.
