• ODI 11g – Insight to the SDK

  - by David Allan

  This post is a useful index into the ODI SDK that cross references the type names from the user interface with the SDK class and also the finder for how to get a handle on the object or objects. The volume of content in the SDK might seem a little ominous, there is a lot there, but there is a general pattern to the SDK that I will describe here. Also I will illustrate some basic CRUD operations so you can see how the SDK usage pattern works. The examples are written in groovy, you can simply run from the groovy console in ODI 11.1.1.6. Entry to the Platform   Object Finder SDK odiInstance odiInstance (groovy variable for console) OdiInstance Topology Objects Object Finder SDK Technology IOdiTechnologyFinder OdiTechnology Context IOdiContextFinder OdiContext Logical Schema IOdiLogicalSchemaFinder OdiLogicalSchema Data Server IOdiDataServerFinder OdiDataServer Physical Schema IOdiPhysicalSchemaFinder OdiPhysicalSchema Logical Schema to Physical Mapping IOdiContextualSchemaMappingFinder OdiContextualSchemaMapping Logical Agent IOdiLogicalAgentFinder OdiLogicalAgent Physical Agent IOdiPhysicalAgentFinder OdiPhysicalAgent Logical Agent to Physical Mapping IOdiContextualAgentMappingFinder OdiContextualAgentMapping Master Repository IOdiMasterRepositoryInfoFinder OdiMasterRepositoryInfo Work Repository IOdiWorkRepositoryInfoFinder OdiWorkRepositoryInfo Project Objects Object Finder SDK Project IOdiProjectFinder OdiProject Folder IOdiFolderFinder OdiFolder Interface IOdiInterfaceFinder OdiInterface Package IOdiPackageFinder OdiPackage Procedure IOdiUserProcedureFinder OdiUserProcedure User Function IOdiUserFunctionFinder OdiUserFunction Variable IOdiVariableFinder OdiVariable Sequence IOdiSequenceFinder OdiSequence KM IOdiKMFinder OdiKM Load Plans and Scenarios   Object Finder SDK Load Plan IOdiLoadPlanFinder OdiLoadPlan Load Plan and Scenario Folder IOdiScenarioFolderFinder OdiScenarioFolder Model Objects Object Finder SDK Model IOdiModelFinder OdiModel Sub Model IOdiSubModel OdiSubModel DataStore IOdiDataStoreFinder OdiDataStore Column IOdiColumnFinder OdiColumn Key IOdiKeyFinder OdiKey Condition IOdiConditionFinder OdiCondition Operator Objects   Object Finder SDK Session Folder IOdiSessionFolderFinder OdiSessionFolder Session IOdiSessionFinder OdiSession Schedule OdiSchedule How to Create an Object? Here is a simple example to create a project, it uses IOdiEntityManager.persist to persist the object. import oracle.odi.domain.project.OdiProject; import oracle.odi.core.persistence.transaction.support.DefaultTransactionDefinition; txnDef = new DefaultTransactionDefinition(); tm = odiInstance.getTransactionManager() txnStatus = tm.getTransaction(txnDef) project = new OdiProject("Project For Demo", "PROJECT_DEMO") odiInstance.getTransactionalEntityManager().persist(project) tm.commit(txnStatus) How to Update an Object? This update example uses the methods on the OdiProject object to change the project’s name that was created above, it is then persisted. import oracle.odi.domain.project.OdiProject; import oracle.odi.domain.project.finder.IOdiProjectFinder; import oracle.odi.core.persistence.transaction.support.DefaultTransactionDefinition; txnDef = new DefaultTransactionDefinition(); tm = odiInstance.getTransactionManager() txnStatus = tm.getTransaction(txnDef) prjFinder = (IOdiProjectFinder)odiInstance.getTransactionalEntityManager().getFinder(OdiProject.class); project = prjFinder.findByCode("PROJECT_DEMO"); project.setName("A Demo Project"); odiInstance.getTransactionalEntityManager().persist(project) tm.commit(txnStatus) How to Delete an Object? Here is a simple example to delete all of the sessions, it uses IOdiEntityManager.remove to delete the object. import oracle.odi.domain.runtime.session.finder.IOdiSessionFinder; import oracle.odi.domain.runtime.session.OdiSession; import oracle.odi.core.persistence.transaction.support.DefaultTransactionDefinition; txnDef = new DefaultTransactionDefinition(); tm = odiInstance.getTransactionManager() txnStatus = tm.getTransaction(txnDef) sessFinder = (IOdiSessionFinder)odiInstance.getTransactionalEntityManager().getFinder(OdiSession.class); sessc = sessFinder.findAll(); sessItr = sessc.iterator() while (sessItr.hasNext()) {   sess = (OdiSession) sessItr.next()   odiInstance.getTransactionalEntityManager().remove(sess) } tm.commit(txnStatus) This isn't an all encompassing summary of the SDK, but covers a lot of the content to give you a good handle on the objects and how they work. For details of how specific complex objects are created via the SDK, its best to look at postings such as the interface builder posting here. Have fun, happy coding!

• How to deploy Document Set using CAML in SharePoint2010 solution package

  - by ybbest

  In my last post, I showed you how to use Document Set using SharePoint UI in the browser. In this post, I’d like to show you how to create the same Document Set using CAML and SharePoint solution package. You can download the complete solution here. 1. Create the Application Number site column using the SharePoint empty element item template in VS2010 <?xml version="1.0" encoding="utf-8"?> <Elements xmlns="http://schemas.microsoft.com/sharepoint/"> <Field Type="Text" DisplayName="ApplicationNumber" Required="FALSE" EnforceUniqueValues="FALSE" Indexed="FALSE" MaxLength="255" Group="YBBEST" ID="{916bf3af-5ec1-4441-acd8-88ff62ab1b7e}" Name="ApplicationNumber" ></Field> </Elements> 2. Create the Loan Application Form and Loan Contract Form content types. <?xml version="1.0" encoding="utf-8"?> <Elements xmlns="http://schemas.microsoft.com/sharepoint/"> <!-- Parent ContentType: Document (0x0101) --> <ContentType ID="0x0101005dfbf820ce3c49f69c73a00e0e0e53f6" Name="Loan Contract Form" Group="YBBEST" Description="Loan Contract Form" Inherits="TRUE" Version="0"> <FieldRefs> <FieldRef ID="916bf3af-5ec1-4441-acd8-88ff62ab1b7e" Name="ApplicationNumber" DisplayName="ApplicationNumber" /> </FieldRefs> </ContentType> <!-- Parent ContentType: Document (0x0101) --> <ContentType ID="0x010100f3016e3d03454b93bc4d6ab63941c0d2" Name="Loan Application Form" Group="YBBEST" Description="Loan Application Form" Inherits="TRUE" Version="0"> <FieldRefs> <FieldRef ID="916bf3af-5ec1-4441-acd8-88ff62ab1b7e" Name="ApplicationNumber" DisplayName="ApplicationNumber" /> </FieldRefs> </ContentType> </Elements> 3. Create the Loan Application Document Set. 4. Create the Document Set Welcome Page using the SharePoint Module item template. Notes: 1.When creating document set content type , you need to set the  Inherits=”FALSE”  or remove the  Inherits=”TRUE” from the content type definition (default is  Inherits=”FALSE”) . This is the Document Set limitation in the current version of SharePoint2010. Because of this , you also need to manually  attach the event receiver and  Document Set welcome page to your custom Document Set Content Type. 2. Shared Fields are push down only: 3. Not available in SharePoint foundation (only SharePoint Server 2010). 4. You can’t have folders within document sets (you can place document sets in folders though). For a complete limitation and considerations , you can see the references for details. References: Document Set Limitations and Considerations in SharePoint 2010 1 Document Set Limitations and Considerations in SharePoint 2010 2 Document Sets planning (SharePoint Server 2010) Import Document Sets Issue http://msdn.microsoft.com/en-us/library/gg581064.aspx http://channel9.msdn.com/Events/TechEd/NorthAmerica/2010/OSP305 DocumentSet Class

• How to use crontab, .netrc, and git push?

  - by Jon

  Hi all, I am in the process of automating the backups from various servers to a central point then pushing those config changes into a git repo so i can track any changes over time. The rest of the scripts are working well, I can copy / rsync the files across the network to a central point. The last script is to get the config files to be put into / updated in repository. The script is as follows: #!/bin/bash clear SERVERNAME="betty" SCRIPTDIR="/home/jon" GITROOT="/tmp/git" TEMPROOT="/tmp/backups" BACKUPROOTDIR="/mnt/backups" echo " - running as user: $UID" echo "backingup git config on $SERVERNAME" echo "" # check to see if root backup folder exists, otherwise create it. if [ -d $GITROOT ]; then rm -rf $GITROOT fi mkdir $GITROOT cd $GITROOT echo " - testing if home is where I think it should be!" echo $HOME echo " - testing if it can see netrc" tail $HOME/.netrc git clone http://192.168.10.97:8000/repositories/HOH-config-backups.git cd HOH-config-backups echo " - copy Configuration Folders across" cp -r $BACKUPROOTDIR/Configuration/* $GITROOT/HOH-config-backups/ cp -r $BACKUPROOTDIR/scripts $GITROOT/HOH-config-backups/ git add . git commit -a -m "committing any new configuration changes!" git push origin master echo "" echo "Git repo updated" echo "" echo " - backing up this script" FIREWIGSCRIPTLOC="$BACKUPROOTDIR/scripts/$SERVERNAME" if [ ! -d $FIREWIGSCRIPTLOC ]; then mkdir $FIREWIGSCRIPTLOC fi cp /home/jon/gitConfig.sh $FIREWIGSCRIPTLOC The git repo is on a different machine in the network using Apache and HTTP-backend.exe (smart HTTP protocol). If I run this script as me "jon" it works. If I run it in crontab it fails. git uses the /home/jon/.netrc file for authentication: machine 192.168.10.97 login gitconfig password 1234579 The log from crontab is: TERM environment variable not set. - running as user: 1000 backingup git config on betty - testing if home is where I think it should be! /home/jon - testing if it can see netrc machine 192.168.10.97 login gitconfig password 1234579 got 08de5bc2b27b4940d9412256e76d5e3c3d9dbcdd walk 08de5bc2b27b4940d9412256e76d5e3c3d9dbcdd got be880f2d306778a538d592e7a02eb19f416612f7 got bd387e8def9f77aafa798bf53e80d949aba443e8 got 1bc1a59e12775841d4c59d77c63b8a73823138c2 walk bd387e8def9f77aafa798bf53e80d949aba443e8 Getting alternates list for http://192.168.10.97:8000/repositories/HOH-config-backups.git got 030512237bca72faf211e0e8ec2906164eac34f6 got 9bc2f575240bc1f61ff7d69777ce1a165d06b184 got b8400f7f01429104a9d4786a6bb1a16d293e37c1 got 2403b5bf611010e0b401f776f0e23b09ce744838 got 1a27944c48269ef3608a8f2466e43402d06faac0 got b686f45b7d57af4fa8ca0d528bb85216d6247e19 Getting pack list for http://192.168.10.97:8000/repositories/HOH-config-backups.git Getting index for pack ae881957c0f0e8c22eb6cc889a22ef78eb4ce6ff Getting pack ae881957c0f0e8c22eb6cc889a22ef78eb4ce6ff which contains ff84d6d48e9326066438d167a10251218d612b3d walk b686f45b7d57af4fa8ca0d528bb85216d6247e19 got 364e30daec17814073e668f490bb84af891fe1f7 got 23f6497e7f9b80e0d90adad73bd0407a0e5ac6ce got 9e77c47574b5e23ea669afe0c23ab235e4917ee1 got 6654e0d328a216b3783e98c47206cb2d01b3353d got 28821ffd437d2689ffb82c6e4b9c3f5372c95c4b got 8c384a24f645389e4d4b08013c79e9e73a658342 got d203be0123736ee025ce20c081f1489098648dfc got 1852603bf7709e71417d8ccec02390279d533642 got fb753a26b20b04694419fce8ecdaa8dbec105cf1 got 736028997cd84dd1c135f57e9d246674b9cd0b9d got 7af836249e20096d0476a548d5be702a071cdd4b got 240dc39d9db50df63073fc7927b2d002dfa0f54c got 93abd36e3935a01011eb753b635a1a0e984bf31e got c6269e28fecf4d8d0d98b9358aecb3acff02df44 got b0aa29432f73e64032682a351d436c24b14078ab walk 240dc39d9db50df63073fc7927b2d002dfa0f54c got 58fb66d9f35f8a5e32ff4683309c5f0c2a3a03c5 got 0da2def4de0565483cdbe6b87418ee2beb122e58 got 0f6a86c6f87ed52ad2ed01e5c6edd661d364930c got 437a93d27b5bb89c739a0564a34a616e832c3ebe got fe0385abe5c0acd8462268dac330bae00e934f1b got 24259f8f5c5c9ee974a75fe3d1e07c02e3e20fe9 got d29f624bf1a5eceedaa86c10fee35f62747c7d04 got 0154e4c987132585ea7a92b77d02dba285512d6b got eda8bf526567c25ee70addb2ad3c3c6aa57eac77 got 9f3d9d7262d66f9fa4f6a13b7c86199953f4bc4e got 8e20881e19667aa22245d0598646991067455a4d got abb1123145689b35eb19519952c71253ee45fa98 got dfeff593c79b4156ce2ce1adf043d0e80356488c got e20c5b48b1d360e0bcf34189e3f3d2bbf23e92cc got b13eb81cc274780322ecf786372320343926bec9 walk 8de83868b3fac748b0a55eba16c8f668ec852abb got b5961421bbc42afe7a07cc1c8b615aba26ba74d7 got 2650ba819019df4193b482733e29ca79b29f3f2c got b3111e1be8103e91803a97a817ed81f28025aca1 got b060be934d709684f5eb5dad3c03932a3589e864 got cf70d2043f081d7a4438e9d5a290a9f986c84060 got 80bf0f1cc836feab86d6935bb7968d8555a8d531 got da318d167920e34bc6573e4fc236249ccbbee316 got d82ac853d387b760149599e6e1ab96403f6ec672 got 0005f691d1f46550fdb4e56025f52e30a5b18cc2 Initialized empty Git repository in /tmp/git/HOH-config-backups/.git/ - copy Configuration Folders across Created commit 424df2f: committing any new configuration changes! 3 files changed, 55 insertions(+), 1 deletions(-) create mode 100755 scripts/betty/gitConfig.sh error: Cannot access URL http://192.168.10.97:8000/repositories/HOH-config-backups.git/, return code 22 error: failed to push some refs to 'http://192.168.10.97:8000/repositories/HOH-config-backups.git' Git repo updated - backing up this script cp: cannot create regular file `/mnt/backups/scripts/betty/gitConfig.sh': Permission denied my crontab is: # m h dom mon dow command 04 * * * * /home/jon/gitConfig.sh > /tmp/gitconfig.log 2>&1 I open it by doing: $crontab -e i.e. not as root.

• What's new in ASP.Net 4.5 and VS 2012 - part 2

  - by nikolaosk

  This is the second post in a series of posts titled "What's new in ASP.Net 4.5 and VS 2012".You can have a look at the first post in this series, here. Please find all my posts regarding VS 2012, here. In this post I will be looking into the various new features available in ASP.Net 4.5 and VS 2012.I will be looking into the enhancements in the HTML Editor,CSS Editor and Javascript Editor.In order to follow along this post you must have Visual Studio 2012 and .Net Framework 4.5 installed in your machine.Download and install VS 2012 using this link.My machine runs on Windows 8 and Visual Studio 2012 works just fine.I will work fine in Windows 7 as well so do not worry if you do not have the latest Microsoft operating system.1) Launch VS 2012 and create a new Web Forms application by going to File - >New Web Site - > ASP.Net Web Forms Site.2) Choose an appropriate name for your web site.3) I would like to point out the new enhancements in the CSS editor in VS 2012. In the Solution Explorer in the Content folder and open the Site.cssThen when I try to change the background-color property of the html element, I get a brand new handy color-picker. Have a look at the picture below  Please note that the color-picker shows all the colors that have been used in this website. Then you can expand the color-picker by clicking on the arrows. Opacity is also supported. Have a look at the picture below4) There are also mobile styles in the Site.css .These are based on media queries.Please have a look at another post of mine on CSS3 media queries. Have a look at the picture below In this case when the maximum width of the screen is less than 850px there will be a new layout that will be dictated by these new rules. Also CSS snippets are supported. Have a look at the picture below I am writing a new CSS rule for an image element. I write the property transform and hit tab and then I have cross-browser CSS handling all of the major vendors.Then I simply add the value rotate and it is applied to all the cross browser options.Have a look at the picture below.  I am sure you realise how productive you can become with all these CSS snippets. 5) Now let's have a look at the new HTML editor enhancements in VS 2012You can drag and drop a GridView web server control from the Toolbox in the Site.master file.You will see a smart tag (that was only available in the Design View) that you can expand and add fields, format the web server control.Have a look at the picture below 6) We also have available code snippets. I type <video and then press tab twice.By doing that I have the rest of the HTML 5 markup completed.Have a look at the picture below 7) I have new support for the input tag including all the HTML 5 types and all the new accessibility features.Have a look at the picture below   8) Another interesting feature is the new Intellisense capabilities. When I change the DocType to 4.01 and the type <audio>,<video> HTML 5 tags, Intellisense does not recognise them and add squiggly lines.Have a look at the picture below All these features support ASP.Net Web forms, ASP.Net MVC applications and Web Pages. 9) Finally I would like to show you the enhanced support that we have for Javascript in VS 2012. I have full Intellisense support and code snippets support.I create a sample javascript file. I type If and press tab. I type while and press tab.I type for and press tab.In all three cases code snippet support kicks in and completes the code stack. Have a look at the picture below We also have full Intellisense support.Have a look at the picture below I am creating a simple function and then type some sort of XML like comments for the input parameters. Have a look at the picture below. Then when I call this function, Intellisense has picked up the XML comments and shows the variables data types.Have a look at the picture below Hope it helps!!!

• MySQL Connect 8 Days Away - Replication Sessions

  - by Mat Keep

  Following on from my post about MySQL Cluster sessions at the forthcoming Connect conference, its now the turn of MySQL Replication - another technology at the heart of scaling and high availability for MySQL. Unless you've only just returned from a 6-month alien abduction, you will know that MySQL 5.6 includes the largest set of replication enhancements ever packaged into a single new release: - Global Transaction IDs + HA utilities for self-healing cluster..(yes both automatic failover and manual switchover available!) - Crash-safe slaves and binlog - Binlog Group Commit and Multi-Threaded Slaves for high performance - Replication Event Checksums and Time-Delayed replication - and many more There are a number of sessions dedicated to learn more about these important new enhancements, delivered by the same engineers who developed them. Here is a summary Saturday 29th, 13.00 Replication Tips and Tricks, Mats Kindahl In this session, the developers of MySQL Replication present a bag of useful tips and tricks related to the MySQL 5.5 GA and MySQL 5.6 development milestone releases, including multisource replication, using logs for auditing, handling filtering, examining the binary log, using relay slaves, splitting the replication stream, and handling failover. Saturday 29th, 17.30 Enabling the New Generation of Web and Cloud Services with MySQL 5.6 Replication, Lars Thalmann This session showcases the new replication features, including • High performance (group commit, multithreaded slave) • High availability (crash-safe slaves, failover utilities) • Flexibility and usability (global transaction identifiers, annotated row-based replication [RBR]) • Data integrity (event checksums) Saturday 29th, 1900 MySQL Replication Birds of a Feather In this session, the MySQL Replication engineers discuss all the goodies, including global transaction identifiers (GTIDs) with autofailover; multithreaded, crash-safe slaves; checksums; and more. The team discusses the design behind these enhancements and how to get started with them. You will get the opportunity to present your feedback on how these can be further enhanced and can share any additional replication requirements you have to further scale your critical MySQL-based workloads. Sunday 30th, 10.15 Hands-On Lab, MySQL Replication, Luis Soares and Sven Sandberg But how do you get started, how does it work, and what are the best practices and tools? During this hands-on lab, you will learn how to get started with replication, how it works, architecture, replication prerequisites, setting up a simple topology, and advanced replication configurations. The session also covers some of the new features in the MySQL 5.6 development milestone releases. Sunday 30th, 13.15 Hands-On Lab, MySQL Utilities, Chuck Bell Would you like to learn how to more effectively manage a host of MySQL servers and manage high-availability features such as replication? This hands-on lab addresses these areas and more. Participants will get familiar with all of the MySQL utilities, using each of them with a variety of options to configure and manage MySQL servers. Sunday 30th, 14.45 Eliminating Downtime with MySQL Replication, Luis Soares The presentation takes a deep dive into new replication features such as global transaction identifiers and crash-safe slaves. It also showcases a range of Python utilities that, combined with the Release 5.6 feature set, results in a self-healing data infrastructure. By the end of the session, attendees will be familiar with the new high-availability features in the whole MySQL 5.6 release and how to make use of them to protect and grow their business. Sunday 30th, 17.45 Scaling for the Web and the Cloud with MySQL Replication, Luis Soares In a Replication topology, high performance directly translates into improving read consistency from slaves and reducing the risk of data loss if a master fails. MySQL 5.6 introduces several new replication features to enhance performance. In this session, you will learn about these new features, how they work, and how you can leverage them in your applications. In addition, you will learn about some other best practices that can be used to improve performance. So how can you make sure you don't miss out - the good news is that registration is still open ;-) And just to whet your appetite, listen to the On-Demand webinar that presents an overview of MySQL 5.6 Replication.

• Invariant code contracts – using class-wide contracts

  - by DigiMortal

  It is possible to define invariant code contracts for classes. Invariant contracts should always hold true whatever member of class is called. In this posting I will show you how to use invariant code contracts so you understand how they work and how they should be tested. This is my randomizer class I am using to demonstrate code contracts. I added one method for invariant code contracts. Currently there is one contract that makes sure that random number generator is not null. public class Randomizer {     private IRandomGenerator _generator;       private Randomizer() { }       public Randomizer(IRandomGenerator generator)     {         _generator = generator;     }       public int GetRandomFromRangeContracted(int min, int max)     {         Contract.Requires<ArgumentOutOfRangeException>(             min < max,             "Min must be less than max"         );           Contract.Ensures(             Contract.Result<int>() >= min &&             Contract.Result<int>() <= max,             "Return value is out of range"         );           return _generator.Next(min, max);     }       [ContractInvariantMethod]     private void ObjectInvariant()     {         Contract.Invariant(_generator != null);     } } Invariant code contracts are define in methods that have ContractInvariantMethod attribute. Some notes: It is good idea to define invariant methods as private. Don’t call invariant methods from your code because code contracts system does not allow it. Invariant methods are defined only as place where you can keep invariant contracts. Invariant methods are called only when call to some class member is made! The last note means that having invariant method and creating Randomizer object with null as argument does not automatically generate exception. We have to call at least one method from Randomizer class. Here is the test for generator. You can find more about contracted code testing from my posting Code Contracts: Unit testing contracted code. There is also explained why the exception handling in test is like it is. [TestMethod] [ExpectedException(typeof(Exception))] public void Should_fail_if_generator_is_null() {     try     {         var randomizer = new Randomizer(null);         randomizer.GetRandomFromRangeContracted(1, 4);     }     catch (Exception ex)     {         throw new Exception(ex.Message, ex);     } } Try out this code – with unit tests or with test application to see that invariant contracts are checked as soon as you call some member of Randomizer class.

• Excel Template Teaser

  - by Tim Dexter

  In lieu of some official documentation I'm in the process of putting together some posts on the new 10.1.3.4.1 Excel templates. No more HTML, maskerading as Excel; far more flexibility than Excel Analyzer and no need to write complex XSL templates to create the same output. Multi sheet outputs with macros and embeddable XSL commands are here. Their capabilities are pretty extensive and I have not worked on them for a few years since I helped put them together for EBS FSG users, so Im back on the learning curve. Let me say up front, there is no template builder, its a completely manual process to build them but, the results can be fantastic and provide yet another 'superstar' opportunity for you. The templates can take hierarchical XML data and walk the structure much like an RTF template. They use named cells/ranges and a hidden sheet to provide the rendering engine the hooks to drop the data in. As a taster heres the data and output I worked with on my first effort: <EMPLOYEES> <LIST_G_DEPT> <G_DEPT> <DEPARTMENT_ID>10</DEPARTMENT_ID> <DEPARTMENT_NAME>Administration</DEPARTMENT_NAME> <LIST_G_EMP> <G_EMP> <EMPLOYEE_ID>200</EMPLOYEE_ID> <EMP_NAME>Jennifer Whalen</EMP_NAME> <EMAIL>JWHALEN</EMAIL> <PHONE_NUMBER>515.123.4444</PHONE_NUMBER> <HIRE_DATE>1987-09-17T00:00:00.000-06:00</HIRE_DATE> <SALARY>4400</SALARY> </G_EMP> </LIST_G_EMP> <TOTAL_EMPS>1</TOTAL_EMPS> <TOTAL_SALARY>4400</TOTAL_SALARY> <AVG_SALARY>4400</AVG_SALARY> <MAX_SALARY>4400</MAX_SALARY> <MIN_SALARY>4400</MIN_SALARY> </G_DEPT> ... </LIST_G_DEPT> </EMPLOYEES> Structured XML coming from a data template, check out the data template progression post. I can then generate the following binary XLS file. There are few cool things to notice in this output. DEPARTMENT-EMPLOYEE master detail output. Not easy to do in the Excel analyzer. Date formatting - this is using an Excel function. Remember BIP generates XML dates in the canonical format. I have formatted the other data in the template using native Excel functionality Salary Total - although in the data I have calculated this in the template Conditional formatting - this is handled by Excel based on the incoming data Bursting department data across sheets and using the department name for the sheet name. This alone is worth the wait! there's more, but this is surely enough to whet your appetite. These new templates are already tucked away in EBS R12 under controlled release by the GL team and have now come to the BIEE and standalone releases in the 10.1.3.4.1+ rollup patch. For the rest of you, its going to be a bit of a waiting game for the relevant teams to uptake the latest BIP release. Look out for more soon with some explanation of how they work and how to put them together!

• Agile Testing Days 2012 – Day 1 – The birth of the #unicorn…

  - by Chris George

  Still riding the high from the tutorial day, I arrived at the conference venue eager to get cracking with the days talks. The opening Keynote was “Disciplined Agile Delivery: The Foundation for Scaling Agile” presented by Scott Ambler. The general ideas behind the methodology such as not re-inventing the wheel, and being goal driven, not prescriptive in how you work certainly struck chords with how we are trying to work in my team. Scott made some interesting observations about how scrum is quite prescriptive and is this really agile? I agreed with quite a few of his points on how what works for one team may not work for another. How a team works should be driven by context and reflection, not process and prescription. However was somewhat dubious about some of the statistics he rolled out towards the end. However, out of this keynote was born something that was to transcend this one presentation. During the talk, Scott mentioned on more than one occasion “In the real world”, and at one point made reference to people living in the land of unicorns and rainbows. The challenge was then laid down on twitter for all speakers to include a unicorn in their presentations… and for the most part this happened! It became an identity for this years conference, and I’m sure something that any attendee will always associate with Agile Testing Days 2012! Following this keynote, I attended “Going agile with Automated GUI Testing – Some personal insights” by Jan Zdunek from codecentric on the vendor track. My speciality is test automation, and in particular GUI testing, so this drew me to this talk more than the others. Thankfully, it was made clear from the very start that this was not peddling any particular product (even though it was on the vendor track), and Jan faithfully stuck to that. Most of the content was not new to me, but it was really comforting to hear someone else with very similar experiences to my own. In particular, things like how GUI testing is hard and is not a silver bullet; how record & replay is NOT a good thing to do (which drew a somewhat inflammatory tweet from an automation company when I tweeted that!). Something that I have started hearing around the place, and has certainly been murmuring at work is to push more of the automation coding onto the developers. After all they are the coding experts. I agree with this to a degree, but I personally enjoy coding and find it very rewarding doing so, therefore I’d be reluctant to give it up. I think there are some better alternatives such as pairing with a developer. Lastly, Jan mentioned, almost in passing, that we should consider virtualisation for gui testing for covering configuration combinations. On my project we’ve been running our win32/.NET GUI tests in cloud virtualisation for a couple of years now… I really should write about that! After lunch the second keynote of the day was by Lisa Crispin and Janet Gregory,”Myths about Agile Testing, De-Bunked”. It started off well… with the two ladies donning Medusa style head bands whilst they disbanding several myths about agile testing! I got the impression that it was perhaps not as slick as they would have liked, but then Janet was suffering with a very sore throat so kept losing her voice. Nevertheless, the presentation was captivating, and they debunked several myths such as : “Testing is dead”, “Testers must write code”, “Agile teams always deliver faster”. I didn’t take many notes for this because it was being recorded, but unfortunately the recordings have not been posted yet so I’ll write more about this when they are. The TestLab was held during a somewhat free for all time during most of the afternoon. It looked intriguing and proved to be one of the surprising experiences of the conference for me. Run by James Lyndsay and Bart Knaack, it consisted of a number of ‘stations’ that offered different testing problems. I opted for testing a mathematical drawing app call Geogebra, the task being to pair up and exploratory test it. After an allotted time, we discussed issues we’d found and decided if we wanted to continue ‘playing’ to which we all agreed! It was fun! The last track talk of the day was “Developers Exploratory Testing – Raising the bar” by Sigge Birgisson. One of the teams at Red Gate have tried Dev or Team exploratory testing a couple of times, and I was really interested to go to the presentation that prompted that. I was not disappointed! Sigge gave a first class presentation, and not only explained what DET was all about, but also how to go about implementing it. Little tips like calling it a ‘workshop’ rather than ‘testing’ I can really see working! Monday evening saw the presentation of the award for the Most Influential Agile Testing Professional Person go to a much deserved Lisa Crispin. The evening was great, with acrobatics, magic and music. My Takeaway Triple from Day 1:  Some of the cool stuff that was suggested in the GUI Testing talk, we are already doing. I should write about that! Testing is not dead! Perhaps testing will become more of a skill than a specific role, but it is certainly not dead. Team/Developer exploratory testing… seems like a no-brainer assuming you have a team who is willing.  Day 2 – Coming soon…

• ISO Files to USB &ndash; The Cheap and Easy Way

  - by RonGarlit

  (DISCLAIMER: Yes there are lots of more elegant ISO software beside the free Microsoft one I’m about to show. But free is free and it has been tested and works for me for making advance bootable USB drives. That is another story. Look up Windows 8 Developer Preview for that one on BING.) For those of use that work with new technology all the time we accumulate a lot of ISO files and have to burn them to CD/DVD’s quite often. But we now have machines without burner in the corporate environment. We have personally Netbooks and light wait highly mobile laptops that do not have DVD burner. USB ports are all the rage and now we have USB 3.0 which is way faster than the 2.0 we are used to. Just looking at the technology, space saving and the cost issues alone is a reason to buy these answer to the DVD’s. So what is special about USB 2.0 and USB 3.0? USB 2 has a maximum speed of 480 Mbps... (That is Megabits per SECOND!!) Now look at the storage that we have with USB thumb drives that are now up to 64 GB in size, cell phone and PDAs that have a lots of internal storage built in well above the 16 Gig range. At the MAX USB 2.0 speed of 480 Mbps a full transfer of data in between devices can take a long time. Time is money right. Every back up a iPhone? Don’t get me started. So at least the engineers have been planning ahead with USB 3.0 which offers a maximum transfer speed of 4.8 Gbps... (That is Giga bits per SECOND!!) That speed is almost 10 times faster than USB 2.0 …. We don’t need to do the math on that one do we? But for now I'm thrilled with USB 2.0 and the fact I can get these little 4 Gig USB drives for $4.00 each at Staples on sale. Well that is a no brainer don’t you think. But what can you do with them to replace that DVD. Simply and cheaply put………. THIS! First let’s get an ISO file like the Visual Studio 2010 Ultimate DVD ISO from MSDN to demonstrate with. I develop on several computers so this is a good choice for me. So we downloaded the ISO file and put it in a folder somewhere like this. Next we go download to the Windows 7 USB/DVD Download Tool site and read about the tool. http://www.microsoftstore.com/store/msstore/html/pbPage.Help_Win7_usbdvd_dwnTool And click this like to get the tool and install it. Once it is installed you go to the Start, Programs menu, Windows 7 USB DVD Download Tool folder. And then click the tool to open it up. As you will see it is a sweet, simple tool that was originally designed to put the ISO for Windows 7 which is designed to be bootable on a USB or DVD for us geeks to play with. It is now being used for the Windows 8 Developer Preview by many developers for that for the same purpose it was built for in the past. But for now we will use it to put a NON Bootable ISO on a USB. Hey it does the job and I’m reusing a left over program. Why buy the fancy one or a free trial and clutter up my machine. We will click the BROWSE button and navigate to where we put our ISO file we want to put on the USB drive. Obviously we are going to click NEXT and continue to select a USB Device (you can guess what the DVD button is for). Next we select the USB that we have plugged into one of our laptops USB ports. Then we click the BEGIN COPYING button and the first thing the program does is format our USB drive. Then it starts copying out files out of the ISO and constructing the USB as if it was a DVD. So now that the files are copying to the drive I’m going to warn you. We will error out here. This program was design for bootable ISO’s of which this one is NOT. No problem because what fails it the writing of the bootable data to the drive that isn’t there. No biggie…. Forget the STARTOVER button is even there and click the dialog’s CLOSE button and exit the program. Now go to Windows Explorer and navigate to the USB Device. You can now access everything and even add stuff to the drive. But for me I want to keep this drive for one purpose and that is to install VS2010 on various machines. So the only stuff I’ll add to this is a folder of notes on things on visual studio that I might want to put on other machines I’m installing VS2010 on to. So that is it. Have a nice day! The Ron

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

  - by pinaldave

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

• Silverlight 5 &ndash; What&rsquo;s New? (Including Screenshots &amp; Code Snippets)

  - by mbcrump

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

• SQL SERVER – Weekly Series – Memory Lane – #005

  - by pinaldave

  Here is the list of curetted articles of SQLAuthority.com across all these years. Instead of just listing all the articles I have selected a few of my most favorite articles and have listed them here with additional notes below it. Let me know which one of the following is your favorite article from memory lane. 2006 SQL SERVER – Cursor to Kill All Process in Database I indeed wrote this cursor and when I often look back, I wonder how naive I was to write this. The reason for writing this cursor was to free up my database from any existing connection so I can do database operation. This worked fine but there can be a potentially big issue if there was any important transaction was killed by this process. There is another way to to achieve the same thing where we can use ALTER syntax to take database in single user mode. Read more about that over here and here. 2007 Rules of Third Normal Form and Normalization Advantage – 3NF The rules of 3NF are mentioned here Make a separate table for each set of related attributes, and give each table a primary key. If an attribute depends on only part of a multi-valued key, remove it to a separate table If attributes do not contribute to a description of the key, remove them to a separate table. Correct Syntax for Stored Procedure SP Sometime a simple question is the most important question. I often see in industry incorrectly written Stored Procedure. Few writes code after the most outer BEGIN…END and few writes code after the GO Statement. In this brief blog post, I have attempted to explain the same. 2008 Switch Between Result Pan and Query Pan – SQL Shortcut Many times when I am writing query I have to scroll the result displayed in the result set. Most of the developer uses the mouse to switch between and Query Pane and Result Pane. There are few developers who are crazy about Keyboard shortcuts. F6 is the keyword which can be used to switch between query pane and tabs of the result pane. Interesting Observation – Use of Index and Execution Plan Query Optimization is a complex game and it has its own rules. From the example in the article we have discovered that Query Optimizer does not use clustered index to retrieve data, sometime non clustered index provides optimal performance for retrieving Primary Key. When all the rows and columns are selected Primary Key should be used to select data as it provides optimal performance. 2009 Interesting Observation – TOP 100 PERCENT and ORDER BY If you pull up any application or system where there are more than 100 SQL Server Views are created – I am very confident that at one or two places you will notice the scenario wherein View the ORDER BY clause is used with TOP 100 PERCENT. SQL Server 2008 VIEW with ORDER BY clause does not throw an error; moreover, it does not acknowledge the presence of it as well. In this article we have taken three perfect examples and demonstrated which clause we should use when. Comma Separated Values (CSV) from Table Column A Very common question – How to create comma separated values from a table in the database? The answer is also very common if we use XML. Check out this article for quick learning on the same subject. Azure Start Guide – Step by Step Installation Guide Though Azure portal has changed a quite bit since I wrote this article, the concept used in this article are not old. They are still valid and many of the functions are still working as mentioned in the article. I believe this one article will put you on the track to use Azure! Size of Index Table for Each Index – Solution Earlier I have posted a small question on this blog and requested help from readers to participate here and provide a solution. The puzzle was to write a query that will return the size for each index that is on any particular table. We need a query that will return an additional column in the above listed query and it should contain the size of the index. This article presents two of the best solutions from the puzzle. 2010 Well, this week in 2010 was the week of puzzles as I posted three interesting puzzles. Till today I am noticing pretty good interesting in the puzzles. They are tricky but for sure brings a great value if you are a database developer for a long time. I suggest you go over this puzzles and their answers. Did you really know all of the answers? I am confident that reading following three blog post will for sure help you enhance the experience with T-SQL. SQL SERVER – Challenge – Puzzle – Usage of FAST Hint SQL SERVER – Puzzle – Challenge – Error While Converting Money to Decimal SQL SERVER – Challenge – Puzzle – Why does RIGHT JOIN Exists 2011 DVM sys.dm_os_sys_info Column Name Changed in SQL Server 2012 Have you ever faced a situation where something does not work? When you try to fix it - you enjoy fixing it and started to appreciate the breaking changes. Well, this was exactly I felt yesterday. Before I begin my story, I want to candidly state that I do not encourage anybody to use * in the SELECT statement. Now the disclaimer is over – I suggest you read the original story – you will love it! Get Directory Structure using Extended Stored Procedure xp_dirtree Here is the question to you – why would you do something in SQL Server where you can do the same task in command prompt much easily. Well, the answer is sometime there are real use cases when we have to do such thing. This is a similar example where I have demonstrated how in SQL Server 2012 we can use extended stored procedure to retrieve directory structure.

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

  - by pinaldave

  Earlier I wrote a blog post about how to install DQS in SQL Server 2012. Today I decided to write a second part of this series where I explain how to use DQS, however, as soon as I started the DQS client, I encountered an error that will not let me pass through and connect with DQS client. It was a bit strange to me as everything was functioning very well when I left it last time.  The error was very big but here are the first few words of it. Cannot connect to server. A .NET Framework error occurred during execution of user-defined routine or aggregate “SetDataQualitySessions”: System.Data.SqlClient.SqlException (0×80131904): A .NET Framework error occurred during execution of user-defined routine or aggregate “SetDataQualitySessionPhaseTwo”: The error continues – here is the quick screenshot of the error. As my initial attempts could not fix the error I decided to search online and I finally received a wonderful solution from Microsoft Site. The error has happened due to latest update I had installed on .NET Framework 4. There was a  mismatch between the Module Version IDs (MVIDs) of the SQL Common Language Runtime (SQLCLR) assemblies in the SQL Server 2012 database and the Global Assembly Cache (GAC). This mismatch was to be resolved for the DQS to work properly. The workaround is specified here in detail. Scroll to subtopic 4.23 Some .NET Framework 4 Updates Might Cause DQS to Fail. The script was very much straight forward. Here are the few things to not to miss while applying workaround. Make sure DQS client is properly closed The NETAssemblies is based on your OS. NETAssemblies for 64 bit machine – which is my machine is “c:\windows\Microsoft.NET\Framework64\v4.0.30319″. If you have Winodws installed on any other drive other than c:\windows do not forget to change that in the above path. Additionally if you have 32 bit version installed on c:\windows you should use path as ”c:\windows\Microsoft.NET\Framework\v4.0.30319″ Make sure that you execute the script specified in 4.23 sections in this article in the database DQS_MAIN.

• Upgrading to Oracle Enterprise Manager 12c Release 2: Top Tips One Must Know

  - by AnkurGupta

  Recently Oracle announced incremental release of Enterprise Manager 12c called Enterprise Manager 12c Release 2 (EM12c R2) which includes several new exciting features (Press announcement). Right before the official release, we upgraded an internal production site from EM 12c R1 to EM 12c R2 and had an extremely pleasant experience. Let me share few key takeaways as well as few tips from this upgrade exercise. I - Why Should You Upgrade To Enterprise Manager 12c Release 2 While an upgrade is usually recommended primarily to take benefit of the latest features (which is valid for this upgrade as well), I found several other compelling reasons purely from deployment perspective. Standardize your EM deployment:  Enterprise Manager comprises of several different components (OMS, agents, plug-ins, etc) and it might be possible that these are at varied patch levels in your environment. For instance, in case of an environment containing Bundle Patch 1 (customer announcement), there is a good chance that you may not have all the components up-to-date. There are two possible reasons. Bundle Patch 1 involved patching different components (OMS, agents, plug-ins) with multiple one-off patches which may not have been applied to all components yet. Bundle Patch 1 for different platforms were not released together. Which means you may not have got the chance to patch all the components on different platforms. Note: BP1 patches are not mandatory to upgrade to EM12c R2 release EM 12c R2 provides an excellent opportunity to standardize your Cloud Control environment (OMS, repository and agents) and plug-ins to latest versions in single shot. All platform releases are made available simultaneously: For the very first time in the history of EM release, all the platforms were released on day one itself, which means you do not need to wait for platform specific binaries for EM OMS or Agent to perform install or upgrades in a heterogeneous environment. Highly refined and automated process – Upgrade process is by far the smoothest and the cleanest as compared to previous releases of Enterprise manager. Following are the ones that stand out. Automatic Plug-in management – Plug-in upgrade along with new plug-in deployment is supported in upgrade installer wizard which means bulk of the updates to OMS and repository can be done in the same workflow. Saves time and minimizes user inputs. Plug-in Upgrade or Migrate Auto Update: While doing the OMS and repository upgrade, you can use Auto Update screen in Oracle Universal Installer to check for any updates/patches. That will help you to avoid the know issues and will make sure that your upgrade is successful. Allows mass upgrade of EM Agents – A new dedicated menu has been added in the EM console for agent upgrade. Agent upgrade workflow is extremely simple that requires agent name as the only input. ADM / JVMD Manager/Agent upgrade – complete process is supported via UI screens. EM12c R2 Upgrade Guide is much simpler to follow as compared to those for earlier releases. This is attributed to the simpler upgrade process. Robust and Performing Platform: EM12c R2 release not only includes several new features, but also provides a more stable platform which incorporates several fixes and enhancements in the Enterprise Manager framework. II - Few Tips To Remember In my last post (blog link) I shared few tips and tricks from my experience applying the Bundle Patch. Recently I upgraded the same site to EM 12c R2 and found few points that you must take note of, while planning this upgrade. The tips below are also applicable to EM 12c R1 environments that do not have Bundle Patch 1 patches applied. Verify the monitored application certification – Specific targets like E-Business Suite have not yet been certified as managed target in EM 12c R2. Therefore make sure to recheck the Enterprise Manager certification Matrix on My Oracle Support before planning the upgrade. Plan downtime – Because EM 12c R2 is an incremental release of EM 12c, for EM 12c R1 to EM 12c R2 upgrade supports only 1-system upgrade approach, which mean there will be downtime. OMS name change after upgrade – In case of multi OMS environments, additional OMS is renamed after upgrade, which has few implications when you upgrade JVMD and ADP agents on OMS. This is well documented in upgrade guide but make sure you read through all the notes. Upgrading BI Publisher– EM12c R2 is certified with BI Publisher 11.1.1.6.0 only. Therefore in case you are using EM 12c R1 which is integrated with BI Publisher 11.1.1.5.0, you must upgrade the BI Publisher to 11.1.1.6.0. Follow the steps from Advanced Installation and Configuration Guide here. Perform Post upgrade Tasks – Make sure to perform post upgrade steps mentioned in documentation here. These include critical changes that must be done right after upgrade to get the right configuration. For instance Database plug-in should be upgraded to Revision 3 (12.1.0.2.0 [u120804]). Delete old OMS Home – EM12c R1 to EM12c R2 is an out of place upgrade, which means it creates a new oracle home for OMS, plug-ins, etc. Therefore please ensure that You have sufficient extra space for new OMS before starting the upgrade process. You clean up the old OMS home after the upgrade process. Steps are available here. DO NOT remove the agent home on OMS host, because agent is upgraded in-place. If you have standby OMS setup then do look into the steps to upgrade the standby OMS from the upgrade guide before going ahead. Read the right documentation – Make sure to follow the Upgrade guide which provides the most comprehensive information on EM12c R2 upgrade process. Additionally you can refer other resources to get familiar with upgrade concepts. Recorded webcast - Oracle Enterprise Manager Cloud Control 12c Release 2 Installation and Upgrade Overview Presentation - Understanding Enterprise Manager 12.1.0.2 Upgrade We are very excited about this latest release and will look forward to hear back any feedback from your upgrade experience!

• How to Automate your Database Documentation

  - by Jonathan Hickford

  In my previous post, “Automating Deployments with SQL Compare command line” I looked at how teams can automate the deployment and post deployment validation of SQL Server databases using the command line versions of Red Gate tools. In this post I’m looking at another use for the command line tools, namely using them to generate up-to-date documentation with every database change. There are many reasons why up-to-date documentation is valuable. For example when somebody new has to work on or administer a database for the first time, or when a new database comes into service. Having database documentation reduces the risks of making incorrect decisions when making changes. Documentation is very useful to business intelligence analysts when writing reports, for example in SSRS. There are a couple of great examples talking about why up to date documentation is valuable on this site:  Database Documentation – Lands of Trolls: Why and How? and Database Documentation Using SQL Doc. The short answer is that it can save you time and reduce risk when you need that most! SQL Doc is a fast simple tool that automatically generates database documentation. It can create documents in HTML, Word or pdf files. The documentation contains information about object definitions and dependencies, along with any other information you want to associate with each object. The SQL Doc GUI, which is included in Red Gate’s SQL Developer Bundle and SQL Toolbelt, allows you to add additional notes to objects, and customise which objects are shown in the docs.  These settings can be saved as a .sqldoc project file. The SQL Doc command line can use this project file to automatically update the documentation every time the database is changed, ensuring that documentation that is always up to date. The simplest way to keep documentation up to date is probably to use a scheduled task to run a script every day. However if you have a source controlled database, or are using a Continuous Integration (CI) server or a build server, it may make more sense to use that instead. If  you’re using SQL Source Control or SSDT Database Projects to help version control your database, you can automatically update the documentation after each change is made to the source control repository that contains your database. To get this automation in place,  you can use the functionality of a Continuous Integration (CI) server, which can trigger commands to run when a source control repository has changed. A CI server will also capture and save the documentation that is created as an artifact, so you can always find the exact documentation for a specific version of the database. This forms an always up to date data dictionary. If you don’t already have a CI server in place there are several you can use, such as the free open source Jenkins or the free starter editions of TeamCity. I won’t cover setting these up in this article, but there is information about using CI servers for automating database tasks on the Red Gate Database Delivery webpage. You may be interested in Red Gate’s SQL CI utility (part of the SQL Automation Pack) which is an easy way to update a database with the latest changes from source control. The PowerShell example below shows how to create the documentation from a database. That database might be your integration database or a shared development database that is always up to date with the latest changes. $serverName = "server\instance" $databaseName = "databaseName" # If you want to document multiple databases use a comma separated list $userName = "username" $password = "password" # Path to SQLDoc.exe $SQLDocPath = "C:\Program Files (x86)\Red Gate\SQL Doc 3\SQLDoc.exe" $arguments = @( "/server:$($serverName)", "/database:$($databaseName)", "/username:$($userName)", "/password:$($password)", "/filetype:html", "/outputfolder:.", # "/project:$args[0]", # If you already have a .sqldoc project file you can pass it as an argument to this script. Values in the project will be overridden with any options set on the command line "/name:$databaseName Report", "/copyrightauthor:$([Environment]::UserName)" ) write-host $arguments & $SQLDocPath $arguments There are several options you can set on the command line to vary how your documentation is created. For example, you can document multiple databases or exclude certain types of objects. In the example above, we set the name of the report to match the database name, and use the current Windows user as the documentation author. For more examples of how you can customise the report from the command line please see the SQL Doc command line documentation If you already have a .sqldoc project file, or wish to further customise the report by including or excluding specific objects, you can use this project on the command line. Any settings you specify on the command line will override the defaults in the project. For details of what you can customise in the project please see the SQL Doc project documentation. In the example above, the line to use a project is commented out, but you can uncomment this line and then pass a path to a .sqldoc project file as an argument to this script.  Conclusion Keeping documentation about your databases up to date is very easy to set up using SQL Doc and PowerShell. By using a CI server to run this process you can trigger the documentation to be run on every change to a source controlled database, and keep historic documentation available. If you are considering more advanced database automation, e.g. database unit testing, change script generation, deploying to large numbers of targets and backup/verification, please email me at [email protected] for further script samples or if you have any questions.

• Team Leaders & Authors - Manage and Report Workflow using "Print an Outline" in UPK

  - by [email protected]

  Did you know you can "print an outline?" You can print any outline or portion of an outline. Why might you want to "print an outline" in UPK... Have you ever wondered how many topics you have recorded, how many of your topics are ready for review, or even better, how many topics are complete! Do you need to report your project status to management? Maybe you just like to have a copy of your outline to refer to during development. Included in this output is the outline structure as well as the layout defined in the Details View of the Outline Editor. To print an outline, you must open either a module or section in the Outline Editor. A set of default data columns is automatically included in the output; however, you can configure which columns you want to appear in the report by switching to the Details view and customizing the columns. (To learn more about customizing your columns refer to the Add and Remove Columns section of the Content Development.pdf guide) To print an outline from the Outline Editor: 1. Open a module or section document in the Outline Editor. 2. Expand the documents to display the details that you want included in the report. 3. On the File menu, choose Print and use the toolbar icons to print, view, or save the report to a file. Personally, I opt to save my outline in Microsoft Excel. Using the delivered features of Microsoft Excel you can add columns of information, such as development notes, to your outline or you can graph and chart your Project status. As mentioned above you can configure what columns you want to appear in the outline. When utilizing the Print an Outline feature in conjunction with the Managing Workflow features of the UPK Multi-user instance you as a Team Lead or Author can better report project status. Read more about Managing Workflow below. Managing Workflow: The Properties toolpane contains special properties that allow authors to track document status or State as well as assign Document Ownership. Assign Content State The State property is an editable property for communicating the status of a document. This is particularly helpful when collaborating with other authors in a development team. Authors can assign a state to documents from the master list defined by the administrator. The default list of States includes (blank), Not Started, Draft, In Review, and Final. Administrators can customize the list by adding, deleting or renaming the values. To assign a State value to a document: 1. Make sure you are working online. 2. Display the Properties toolpane. 3. Select the document(s) to which you want to assign a state. Note: You can select multiple documents using the standard Windows selection keys (CTRL+click and SHIFT+click). 4. In the Workflow category, click in the State cell. 5. Select a value from the list. Assign Document Ownership In many enterprises, multiple authors often work together developing content in a team environment. Team leaders typically handle large projects by assigning specific development responsibilities to authors. The Owner property allows team leaders and authors to assign documents to themselves and other authors to track who is responsible for a specific document. You view and change document assignments for a document using the Owner property in the Properties toolpane. To assign a document owner: 1. Make sure you are working online. 2. On the View menu, choose Properties. 3. Select the document(s) to which you want to assign document responsibility. Note: You can select multiple documents using the standard Windows selection keys (CTRL+click and SHIFT+click). 4. In the Workflow category, click in the Owner cell. 5. Select a name from the list. Is anyone out there already using this feature? Share your ideas with the group. Those of you new to this feature, give it a test drive and let us know what you think. - Kathryn Lustenberger, Oracle UPK & Tutor Outbound Product Management

• Sound vs. Valid Argument

  - by MarkPearl

  Today I spent some time reviewing my Formal Logic course for my up coming exam. I came across a section that I have never really explored in any proper depth… the difference between a valid argument and a sound argument. Here go some notes I made… What is an argument? In this case we are not referring to a verbal fight, but more what we call a set of premise followed by a conclusion. Before we go further we need to understand what a premise is… a premise is a statement that an argument claims will induce or justify a conclusion. Think of a premise as an assumption that something is true. So, an argument can consist of one or more premises and a conclusion… When is an argument valid? An argument can be either valid or invalid. An argument is valid if, and only if, it is impossible for there to be a situation in which all it's premises are TRUE and it's conclusion is FALSE. It is generally easier to determine if an argument is invalid. Do this by applying the following… Assume that all the premises are true, then ask yourself if it is now possible for the conclusion to be false. If the answer is "yes," the argument is invalid. If it's "no," the argument is valid. Example 1… P1 – Mark is Tall P2 – Mark is a boy C –  Mark is a tall boy Walkthrough 1… Assume Mark is Tall is true and also assume that Mark is a boy. Based on these two premises, the conclusion is also true – Mark is a tall boy, thus the it is a valid argument. Let’s make this an invalid argument…   Example 2… P1 – Mark is Tall P2 – Mark is a boy C – Mark is a short boy Walkthrough 2… This would be an invalid argument, since from the premises we assume that Mark is tall and he is a boy, and then the conclusion goes against this by saying that Mark is short. Thus an invalid argument.   When is an argument sound? An argument is said to be sound when it is valid and all the premises are indeed true (not just assumed to be true). Rephrased, an argument is said to be sound when the conclusion will follow from the premises and the premises are indeed true in real life. In example 1 we were referring to a specific person, if we generalized it a bit we could come up with the following example.   Example 3 P1 – All people called Mark are tall P2 – I know a specific person called Mark C – He is a tall person   In this instance, it is a valid argument (we assume the premises are true, which leads to the conclusion being true), but the argument is NOT sound. In the real world there must be at least one person called Mark who is not tall. Something also to note, all invalid arguments are also unsound – this makes sense, if an argument is not valid, how on earth can it be true in the real world.   What happens when the premises contradict themselves? This is an interesting one… An argument is valid if, and only if, it is impossible for there to be a situation in which all it's premises are TRUE and it's conclusion is FALSE. When premises are contradictory, the argument is always valid because it is impossible for all the premises to be true at one time. Lets look at an example.. P1 - Elvis is dead P2 – Elvis is alive C – Laura is a woolly mammoth This is a valid argument, but not a sound one. Think about it. Is it possible to have a situation in which the premises are true and the conclusion is false? Sure, it's possible to have a situation in which the conclusion is false, but for the argument to be invalid, it has to be possible for the premises to all be true at the same time the conclusion is false. So if the premises can't all be true, the argument is valid. (If you still think the argument is invalid, draw a picture in which the premises are all true and the conclusion is false. Remember, there's only one Elvis, and you can't be both dead and alive.) For more info on this I suggest reading the following blog post.

• BPM Suite 11gR1 Released

  - by Manoj Das

  This morning (April 27th, 2010), Oracle BPM Suite 11gR1 became available for download from OTN and eDelivery. If you have been following our plans in this area, you know that this is the release unifying BEA ALBPM product, which became Oracle BPM10gR3, with the Oracle stack. Some of the highlights of this release are: BPMN 2.0 modeling and simulation Web based Process Composer for BPMN and Rules authoring Zero-code environment with full access to Oracle SOA Suite’s rich set of application and other adapters Process Spaces – Out-of-box integration with Web Center Suite Process Analytics – Native process cubes as well as integration with Oracle BAM You can learn more about this release from the documentation. Notes about downloading and installing Please note that Oracle BPM Suite 11gR1 is delivered and installed as part of SOA 11.1.1.3.0, which is a sparse release (only incremental patch). To install: Download and install SOA 11.1.1.2.0, which is a full release (you can find the bits at the above location) Download and install SOA 11.1.1.3.0 During configure step (using the Fusion Middleware configuration wizard), use the Oracle Business Process Management template supplied with the SOA Suite11g (11.1.1.3.0) If you plan to use Process Spaces, also install Web Center 11.1.1.3.0, which also is delivered as a sparse release and needs to be installed on top of Web Center 11.1.1.2.0 Some early feedback We have been receiving very encouraging feedback on this release. Some quotes from partners are included below: “I just attended a preview workshop on BPM Studio, Oracle's BPMN 2.0 tool, held by Clemens Utschig Utschig from Oracle HQ. The usability and ease to get started are impressive. In the business view analysts can intuitively start modeling, then developers refine in their own, more technical view. The BPM Studio sets itself apart from pure play BPMN 2.0 tools by being seamlessly integrated inside a holistic SOA / BPM toolset: BPMN models are placed in SCA-Composites in SOA Suite 11g. This allows to abstract away the complexities of SOA integration aspects from business process aspects. For UIs in BPMN tasks, you have the richness of ADF 11g based Frontends. With BPM Studio we architects have a new modeling and development IDE that gives us interesting design challenges to grasp and elaborate, since many things BPMN 2.0 are different from good ol' BPEL. For example, for simple transformations, you don't use BPEL "assign" any more, but add the transformation directly to the service call. There is much less XPath involved. And, there is no translation from model to BPEL code anymore, so the awkward process model to BPEL roundtrip, which never really worked as well as it looked on marketing slides, is obsolete: With BPMN 2.0 "the model is the code". Now, these are great times to start the journey into BPM! Some tips: Start Projects smoothly, with initial processes being not overly complex and not using the more esoteric areas of BPMN, to manage the learning path and to stay successful with each iteration. Verify non functional requirements by conducting performance and load tests early. As mentioned above, separate all technical integration logic into SOA Suite or Oracle Service Bus. And - share your experience!” Hajo Normann, SOA Architect - Oracle ACE Director - Co-Leader DOAG SIG SOA   "Reuse of components across the Oracle 11G Fusion Middleware stack, like for instance a Database Adapter, is essential. It improves stability and predictability of the solution. BPM just is one of the components plugging into the stack and reuses all other components." Mr. Leon Smiers, Oracle Solution Architect, Capgemini   “I had the opportunity to follow a hands-on workshop held by Clemens for Oracle partners and I was really impressed of the overall offering of BPM11g. BPM11g allows the execution of BPMN 2.0 processes, without having to transform/translate them first to BPEL in order to be executable. The fact that BPMN uses the same underlying service infrastructure of SOA Suite 11g has a lot of benefits for us already familiar with SOA Suite 11g. BPMN is just another SCA component within a SCA composite and can (re)use all the existing components like Rules, Human Workflow, Adapters and Mediator. I also like the fact that BPMN runs on the same service engine as BPEL. By that all known best practices for making a BPEL  process reliable are valid for BPMN processes as well. Last but not least, BPMN is integrated into the superior end-to-end tracing of SOA Suite 11g. With BPM11g, Oracle offers a very competitive product which will have a big effect on the IT market. Clemens and Jürgen: Thanks for the great workshop! I’m really looking forward to my first project using Oracle BPM11g!” Guido Schmutz, Technology Manager / Oracle ACE Director for Fusion Middleware and SOA, Company:  Trivadis Some earlier feedback were summarized in this post.

• Using the Static Code Analysis feature of Visual Studio (Premium/Ultimate) to find memory leakage problems

  - by terje

  Memory for managed code is handled by the garbage collector, but if you use any kind of unmanaged code, like native resources of any kind, open files, streams and window handles, your application may leak memory if these are not properly handled.  To handle such resources the classes that own these in your application should implement the IDisposable interface, and preferably implement it according to the pattern described for that interface. When you suspect a memory leak, the immediate impulse would be to start up a memory profiler and start digging into that.   However, before you follow that impulse, do a Static Code Analysis run with a ruleset tuned to finding possible memory leaks in your code.  If you get any warnings from this, fix them before you go on with the profiling. How to use a ruleset In Visual Studio 2010 (Premium and Ultimate editions) you can define your own rulesets containing a list of Static Code Analysis checks.   I have defined the memory checks as shown in the lists below as ruleset files, which can be downloaded – see bottom of this post.  When you get them, you can easily attach them to every project in your solution using the Solution Properties dialog. Right click the solution, and choose Properties at the bottom, or use the Analyze menu and choose “Configure Code Analysis for Solution”: In this dialog you can now choose the Memorycheck ruleset for every project you want to investigate.  Pressing Apply or Ok opens every project file and changes the projects code analysis ruleset to the one we have specified here. How to define your own ruleset  (skip this if you just download my predefined rulesets) If you want to define the ruleset yourself, open the properties on any project, choose Code Analysis tab near the bottom, choose any ruleset in the drop box and press Open Clear out all the rules by selecting “Source Rule Sets” in the Group By box, and unselect the box Change the Group By box to ID, and select the checks you want to include from the lists below. Note that you can change the action for each check to either warning, error or none, none being the same as unchecking the check.   Now go to the properties window and set a new name and description for your ruleset. Then save (File/Save as) the ruleset using the new name as its name, and use it for your projects as detailed above. It can also be wise to add the ruleset to your solution as a solution item. That way it’s there if you want to enable Code Analysis in some of your TFS builds.   Running the code analysis In Visual Studio 2010 you can either do your code analysis project by project using the context menu in the solution explorer and choose “Run Code Analysis”, you can define a new solution configuration, call it for example Debug (Code Analysis), in for each project here enable the Enable Code Analysis on Build   In Visual Studio Dev-11 it is all much simpler, just go to the Solution root in the Solution explorer, right click and choose “Run code analysis on solution”.     The ruleset checks The following list is the essential and critical memory checks.  CheckID Message Can be ignored ?

• jQuery Selector Tester and Cheat Sheet

  - by SGWellens

  I've always appreciated these tools: Expresso and XPath Builder. They make designing regular expressions and XPath selectors almost fun! Did I say fun? I meant less painful. Being able to paste/load text and then interactively play with the search criteria is infinitely better than the code/compile/run/test cycle. It's faster and you get a much better feel for how the expressions work. So, I decided to make my own interactive tool to test jQuery selectors:  jQuery Selector Tester.   Here's a sneak peek: Note: There are some existing tools you may like better: http://www.woods.iki.fi/interactive-jquery-tester.html http://www.w3schools.com/jquery/trysel.asp?filename=trysel_basic&jqsel=p.intro,%23choose My tool is different: It is one page. You can save it and run it locally without a Web Server. It shows the results as a list of iterated objects instead of highlighted html. A cheat sheet is on the same page as the tester which is handy. I couldn't upload an .htm or .html file to this site so I hosted it on my personal site here: jQuery Selector Tester. Design Highlights: To make the interactive search work, I added a hidden div to the page: <!--Hidden div holds DOM elements for jQuery to search--><div id="HiddenDiv" style="display: none"></div> When ready to search, the searchable html text is copied into the hidden div…this renders the DOM tree in the hidden div: // get the html to search, insert it to the hidden divvar Html = $("#TextAreaHTML").val();$("#HiddenDiv").html(Html); When doing a search, I modify the search pattern to look only in the HiddenDiv. To do that, I put a space between the patterns.  The space is the Ancestor operator (see the Cheat Sheet): // modify search string to only search in our// hidden div and do the searchvar SearchString = "#HiddenDiv " + SearchPattern;try{    var $FoundItems = $(SearchString);}   Big Fat Stinking Faux Pas: I was about to publish this article when I made a big mistake: I tested the tool with Mozilla FireFox. It blowed up…it blowed up real good. In the past I’ve only had to target IE so this was quite a revelation. When I started to learn JavaScript, I was disgusted to see all the browser dependent code. Who wants to spend their time testing against different browsers and versions of browsers? Adding a bunch of ‘if-else’ code is a tedious and thankless task. I avoided client code as much as I could. Then jQuery came along and all was good. It was browser independent and freed us from the tedium of worrying about version N of the Acme browser. Right? Wrong! I had used outerHTML to display the selected elements. The problem is Mozilla FireFox doesn’t implement outerHTML. I replaced this: // encode the html markupvar OuterHtml = $('<div/>').text(this.outerHTML).html(); With this: // encode the html markupvar Html = $('<div>').append(this).html();var OuterHtml = $('<div/>').text(Html).html(); Another problem was that Mozilla FireFox doesn’t implement srcElement. I replaced this: var Row = e.srcElement.parentNode;  With this: var Row = e.target.parentNode; Another problem was the indexing. The browsers have different ways of indexing. I replaced this: // this cell has the search pattern  var Cell = Row.childNodes[1];   // put the pattern in the search box and search                    $("#TextSearchPattern").val(Cell.innerText);  With this: // get the correct cell and the text in the cell// place the text in the seach box and serachvar Cell = $(Row).find("TD:nth-child(2)");var CellText = Cell.text();$("#TextSearchPattern").val(CellText);   So much for the myth of browser independence. Was I overly optimistic and gullible? I don’t think so. And when I get my millions from the deposed Nigerian prince I sent money to, you’ll see that having faith is not futile. Notes: My goal was to have a single standalone file. I tried to keep the features and CSS to a minimum–adding only enough to make it useful and visually pleasing. When testing, I often thought there was a problem with the jQuery selector. Invariable it was invalid html code. If your results aren't what you expect, don't assume it's the jQuery selector pattern: The html may be invalid. To help in development and testing, I added a double-click handler to the rows in the Cheat Sheet table. If you double-click a row, the search pattern is put in the search box, a search is performed and the page is scrolled so you can see the results. I left the test html and code in the page. If you are using a CDN (non-local) version of the jQuery libraray, the designer in Visual Studio becomes extremely slow.  That's why there are two version of the library in the header and one is commented out. For reference, here is the jQuery documentation on selectors: http://api.jquery.com/category/selectors/ Here is a much more comprehensive list of CSS selectors (which jQuery uses): http://www.w3.org/TR/CSS2/selector.html I hope someone finds this useful.

• Task-It Webinar - Source Code

  Last week I presented a webinar called "Building a real-world application with RadControls for Silverlight 4". For those that didn't get to see the webinar, you can view it here: Building a read-world application with RadControls for Silverlight 4 Since the webinar I've received several requests asking if I could post the source code for the simple application I showed demonstrating some of the techniques used in the development of Task-It, such as MVVM, Commands and Internationalization. This source code is now available for downloadhere. After downloading the source: Extract it to the location of your choice on your hard-drive Open the solution Right-click ModuleProject.Web and selecte 'Set as StartUp Project'. Right-click ProjectTestPage.aspx and selected 'Set as Start Page' Create a database in SQL Server called WebinarProject. Navigate to the Database folder under the WebinarProject directory and run the .sql script against your WebinarProject database. The last two steps are necessary only for the Tasks page to work properly (using WCF RIA Services). Now some notes about each page: Code-behind This is not the way I recommend coding a line-of-business application in Silverlight, but simply wanted to show how the code-behind approach would look. Command This page introduces MVVM and Commands. You'll notice in the XAML that the Command property of theRadMenuItem and the Button are both bound to a SaveCommand. That comes from the view model. If you look in the code- behind of the user control you'll see that an instance of a CommandViewModel is instantiated and set as the DataContext of the UserControl.There is also a listener for the view model's SaveCompleted event. When this is fired, it tells the view (UserControl) to display the MessageBox. Internationalization This sample is similar to the previous one, but instead of using hard-coded strings in the UI, the strings are obtained via binding toview model properties. The view model gets the strings from the .resx files (Strings.resx or Strings.de.resx) under Assets/Resources. If you uncomment the call to ShowGerman() in App.xaml.cs's Application_Startup method and re-run the application, you will see the UI in German. Note that this code, which sets the CurrentCulture and CurrentUICulture on the current thread to "de" (German) is for testing purposes only. RadWindow Once again, very similar to the previous example.The difference is that we are now using a RadWindow to display the 'Saved' message instead of a MessageBox. The advantage here is that we do not have to hold on to a reference to the view model in our code behind so that we can get the 'Saved' message from it. The RadWindow's DataContext is now also bound to the view model, so within its XAML we can bind directly to properties in the view model. Much nicer, and cleaner. One other thing I introduced in this example is the use of spacer Rectangles. Rather than setting a width and/or height on the rectangles for spacing, I am now referencing a style in my ResourceDictionary called StandardSpacerStyle. I like doing this better than using margins or padding because now I have a reusable way to create space between elements, the Rectangle does not show (because I have not set its Fill color), and I can change my spacing throughout the user interface in one place if I'd like. Tasks This page is quite a bit different than the other four. It is a very simple, stripped-down version of the Tasks page in the Task-It application. The Tasks.xaml UserControl has a ContentControl, and the Content of that control is set based on whether we are looking at the list of tasks or editing a task. So it displays one of two child UserControls, which are called List and Details. List has the RadGridView, Details has the form. In the code-behind of the Tasks UserControl I am once again setting its DataContext to a view model class. The nice thing is, whichever child UserControl is being displayed (List or Details) inherits its DataContext from its parent control (Tasks), so I do not have to explicitly set it. The List UserControl simply displays a RadGridView whose ItemsSource is bound to a property in the view model called Tasks, and its SelectedItem property is bound to a property in the view model called SelectedItem. The SelectedItem binding must be TwoWay so that the view is notified when the SelectedItem changes in the view model, and the view model is notified when something changes in the view (like when a user changes the Name and/or DueDate in the form). You'll also notice that the form's TextBox and RadDatePicker are also TwoWay bound to the SelectedItem property in the view model. You can experiment with the binding by removing TwoWay and see how changes in the form do not show up in the RadGridView. So here we have an example of two different views (List and Details) that are both bound to the same view model...and actually, so is the Tasks UserControl, so it is really three views. WCF RIA Services By the way, I am using WCF RIA Services to retrieve data for the RadGridView and save the data when the user clicks the Save button in the form. I created a really simple ADO.NET Entity Data Model in WebinarProject.Web called DataModel.edmx. I also created a simple Domain Data Service called DataService that has methods for retrieving data, inserting, updating and deleting. However I am only using the retrieval and update methods in this sample. Note that I do not currently have any validation in place on the form, as I wanted to keep the sample as simple as possible. Wrap up Technically, I should move the calls to WCF RIA Services out of the view model and put them into a separate layer, but this works for now, and that is a topic for another day! Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• Microsoft ReportViewer SetParameters continuous refresh issue

  - by Ilya Verbitskiy

  Originally posted on: http://geekswithblogs.net/ilich/archive/2013/10/16/microsoft-reportviewer-setparameters-continuous-refresh-issue.aspxI am a big fun of using ASP.NET MVC for building web-applications. It allows us to create simple, robust and testable solutions. However, .NET world is not perfect. There is tons of code written in ASP.NET web-forms. You cannot simply ignore it, even if you want to. Sometimes ASP.NET web-forms controls bring us non-obvious issues. The good example is Microsoft ReportViewer control. I have an example for you. 1: <%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %> 2: <%@ Register Assembly="Microsoft.ReportViewer.WebForms, Version=11.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91" Namespace="Microsoft.Reporting.WebForms" TagPrefix="rsweb" %> 3:   4: <!DOCTYPE html> 5:   6: <html xmlns="http://www.w3.org/1999/xhtml"> 7: <head runat="server"> 8: <title>Report Viewer Continiuse Resfresh Issue Example</title> 9: </head> 10: <body> 11: <form id="form1" runat="server"> 12: <div> 13: <asp:ScriptManager runat="server"></asp:ScriptManager> 14: <rsweb:ReportViewer ID="_reportViewer" runat="server" Width="100%" Height="100%"></rsweb:ReportViewer> 15: </div> 16: </form> 17: </body> 18: </html>   The back-end code is simple as well. I want to show a report with some parameters to a user. 1: protected void Page_Load(object sender, EventArgs e) 2: { 3: _reportViewer.ProcessingMode = ProcessingMode.Remote; 4: _reportViewer.ShowParameterPrompts = false; 5:   6: var serverReport = _reportViewer.ServerReport; 7: serverReport.ReportServerUrl = new Uri("http://localhost/ReportServer_SQLEXPRESS"); 8: serverReport.ReportPath = "/Reports/TestReport"; 9:   10: var reportParameter1 = new ReportParameter("Parameter1"); 11: reportParameter1.Values.Add("Hello World!"); 12:   13: var reportParameter2 = new ReportParameter("Parameter2"); 14: reportParameter2.Values.Add("10/16/2013"); 15:   16: var reportParameter3 = new ReportParameter("Parameter3"); 17: reportParameter3.Values.Add("10"); 18:   19: serverReport.SetParameters(new[] { reportParameter1, reportParameter2, reportParameter3 }); 20: }   I set ShowParametersPrompts to false because I do not want user to refine the search. It looks good until you run the report. The report will refresh itself all the time. The problem caused by ServerReport.SetParameters method in Page_Load. The method cause ReportViewer control to execute the report on the NEXT post back. That is why the page has continuous post-backs. The fix is very simple: do nothing if Page_Load method executed during post-back. 1: protected void Page_Load(object sender, EventArgs e) 2: { 3: if (IsPostBack) 4: { 5: return; 6: } 7:   8: _reportViewer.ProcessingMode = ProcessingMode.Remote; 9: _reportViewer.ShowParameterPrompts = false; 10:   11: var serverReport = _reportViewer.ServerReport; 12: serverReport.ReportServerUrl = new Uri("http://localhost/ReportServer_SQLEXPRESS"); 13: serverReport.ReportPath = "/Reports/TestReport"; 14:   15: var reportParameter1 = new ReportParameter("Parameter1"); 16: reportParameter1.Values.Add("Hello World!"); 17:   18: var reportParameter2 = new ReportParameter("Parameter2"); 19: reportParameter2.Values.Add("10/16/2013"); 20:   21: var reportParameter3 = new ReportParameter("Parameter3"); 22: reportParameter3.Values.Add("10"); 23:   24: serverReport.SetParameters(new[] { reportParameter1, reportParameter2, reportParameter3 }); 25: } You can download sample code from GitHub - https://github.com/ilich/Examples/tree/master/ReportViewerContinuousRefresh

• Data Mining Resources

  - by Dejan Sarka

  There are many different types of analyses, each one with its own pros and cons. Relational reports have a predefined structure, and end users cannot change it. They are simple to use for end users. Reports can use real-time data and snapshots of data to show the state of a report at specific points in time. One of the drawbacks is that report authoring is limited to IT pros and advanced users. Any kind of dynamic restructuring is very limited. If real-time data is used for a report, the report has a negative impact on the performance of the source system. Processing of the reports might be slow because the data comes from relational database management systems, which are not optimized for reporting only. If you create a semantic model of your data, your end users can create ad-hoc report structures. However, the development is more complex because a developer is needed to create these semantic models. For OLAP, you typically use specialized database management systems. You get lightning speed of analyses. End users can use rich and thin clients to interactively change the structure of the report. Typically, they do it graphically. However, the development of an OLAP system is many times quite complex. It involves the preparation and maintenance of an enterprise data warehouse and OLAP cubes. In order to exploit the possibility of real-time restructuring of reports, the users must be both active and educated. The data is usually stale, as it is loaded into data warehouses and OLAP cubes with a scheduled process. With data mining, a structure is not selected in advance; it searches for the structure. As a result, data mining can give you the most valuable results because you can discover patterns you did not expect. A data mining model structure is limited only by the attributes that you use to train the model. One of the drawbacks is that a lot of knowledge is needed for a successful data mining project. End users have to understand the results. Subject matter experts and IT professionals need to understand business problem thoroughly. The development might be sometimes even more complex than the development of OLAP cubes. Each type of analysis has its own place in an enterprise system. SQL Server has tools for all kinds of analyses. However, data mining is the most advanced way of analyzing the data; this is the “I” in BI. In order to get the most out of it, you need to learn quite a lot. In this blog post, I am gathering together resources for learning, including forthcoming events. Books Multiple authors: SQL Server MVP Deep Dives – I wrote an introductory data mining chapter there. Erik Veerman, Teo Lachev and Dejan Sarka: MCTS Self-Paced Training Kit (Exam 70-448): Microsoft SQL Server 2008 - Business Intelligence Development and Maintenance – you can find a good overview of a complete BI solution, including data mining, in this book. Jamie MacLennan, ZhaoHui Tang, and Bogdan Crivat: Data Mining with Microsoft SQL Server 2008 – can’t miss this book if you want to mine your data with SQL Server tools. Michael Berry, Gordon Linoff: Mastering Data Mining: The Art and Science of Customer Relationship Management – data mining from both, business and technical perspective. Dorian Pyle: Data Preparation for Data Mining – an in-depth book about data preparation. Thomas and Ronald Wonnacott: Introductory Statistics – if you thought that you could get away without statistics, then you are not serious about data mining. Jiawei Han and Micheline Kamber: Data Mining Concepts and Techniques – in-depth explanation of the most popular data mining algorithms. Michael Berry and Gordon Linoff: Data Mining Techniques – another book that explains data mining algorithms, more fro a business perspective. Paolo Guidici: Applied Data Mining – very mathematical book, only if you enjoy statistics and mathematics in general. Forthcoming presentations I am presenting two data mining related sessions during the PASS Summit in Charlotte, NC: Wednesday, October 16th, 2013 - Fraud Detection: Notes from the Field – I am showing how to use data mining for a specific business problem. The presentation is based on real-life projects. Friday, October 18th: Excel 2013 Advanced Analytics – I am focusing on Excel Data Mining Add-ins, and how to use them together with Power Pivot and other add-ins. This is the most you can get out of Excel. Sinergija 2013, Belgrade, Serbia Tuesday, October 22nd: Excel 2013 Analytics to the Max – another presentation focusing on the most advanced analytics you can get in Excel. SQL Rally Amsterdam, Netherlands Thursday, November 7th: Advanced Analytics in Excel 2013 – and again I am presenting about data mining in Excel. Why three different titles for the same presentation? I don’t know, I guess I forgot the name I proposed every time right after I sent the proposal. Courses Data Mining with SQL Server 2012 – I wrote a 3-day course for SolidQ. If you are interested in this course, which I could also deliver in a shorter seminar way, you can contact your closes SolidQ subsidiary, or, of course, me directly on addresses [email protected] or [email protected]. This course could also complement the existing courseware portfolio of training providers, which are welcome to contact me as well. OK, now you know: no more excuses, start learning data mining, get the most out of your data

• Big Data – Beginning Big Data – Day 1 of 21

  - by Pinal Dave

  What is Big Data? I want to learn Big Data. I have no clue where and how to start learning about it. Does Big Data really means data is big? What are the tools and software I need to know to learn Big Data? I often receive questions which I mentioned above. They are good questions and honestly when we search online, it is hard to find authoritative and authentic answers. I have been working with Big Data and NoSQL for a while and I have decided that I will attempt to discuss this subject over here in the blog. In the next 21 days we will understand what is so big about Big Data. Big Data – Big Thing! Big Data is becoming one of the most talked about technology trends nowadays. The real challenge with the big organization is to get maximum out of the data already available and predict what kind of data to collect in the future. How to take the existing data and make it meaningful that it provides us accurate insight in the past data is one of the key discussion points in many of the executive meetings in organizations. With the explosion of the data the challenge has gone to the next level and now a Big Data is becoming the reality in many organizations. Big Data – A Rubik’s Cube I like to compare big data with the Rubik’s cube. I believe they have many similarities. Just like a Rubik’s cube it has many different solutions. Let us visualize a Rubik’s cube solving challenge where there are many experts participating. If you take five Rubik’s cube and mix up the same way and give it to five different expert to solve it. It is quite possible that all the five people will solve the Rubik’s cube in fractions of the seconds but if you pay attention to the same closely, you will notice that even though the final outcome is the same, the route taken to solve the Rubik’s cube is not the same. Every expert will start at a different place and will try to resolve it with different methods. Some will solve one color first and others will solve another color first. Even though they follow the same kind of algorithm to solve the puzzle they will start and end at a different place and their moves will be different at many occasions. It is  nearly impossible to have a exact same route taken by two experts. Big Market and Multiple Solutions Big Data is exactly like a Rubik’s cube – even though the goal of every organization and expert is same to get maximum out of the data, the route and the starting point are different for each organization and expert. As organizations are evaluating and architecting big data solutions they are also learning the ways and opportunities which are related to Big Data. There is not a single solution to big data as well there is not a single vendor which can claim to know all about Big Data. Honestly, Big Data is too big a concept and there are many players – different architectures, different vendors and different technology. What is Next? In this 31 days series we will be exploring many essential topics related to big data. I do not claim that you will be master of the subject after 31 days but I claim that I will be covering following topics in easy to understand language. Architecture of Big Data Big Data a Management and Implementation Different Technologies – Hadoop, Mapreduce Real World Conversations Best Practices Tomorrow In tomorrow’s blog post we will try to answer one of the very essential questions – What is Big Data?
