• SQL – Migrate Database from SQL Server to NuoDB – A Quick Tutorial

  - by Pinal Dave

  Data is growing exponentially and every organization with growing data is thinking of next big innovation in the world of Big Data. Big data is a indeed a future for every organization at one point of the time. Just like every other next big thing, big data has its own challenges and issues. The biggest challenge associated with the big data is to find the ideal platform which supports the scalability and growth of the data. If you are a regular reader of this blog, you must be familiar with NuoDB. I have been working with NuoDB for a while and their recent release is the best thus far. NuoDB is an elastically scalable SQL database that can run on local host, datacenter and cloud-based resources. A key feature of the product is that it does not require sharding (read more here). Last week, I was able to install NuoDB in less than 90 seconds and have explored their Explorer and Admin sections. You can read about my experiences in these posts: SQL – Step by Step Guide to Download and Install NuoDB – Getting Started with NuoDB SQL – Quick Start with Admin Sections of NuoDB – Manage NuoDB Database SQL – Quick Start with Explorer Sections of NuoDB – Query NuoDB Database Many SQL Authority readers have been following me in my journey to evaluate NuoDB. One of the frequently asked questions I’ve received from you is if there is any way to migrate data from SQL Server to NuoDB. The fact is that there is indeed a way to do so and NuoDB provides a fantastic tool which can help users to do it. NuoDB Migrator is a command line utility that supports the migration of Microsoft SQL Server, MySQL, Oracle, and PostgreSQL schemas and data to NuoDB. The migration to NuoDB is a three-step process: NuoDB Migrator generates a schema for a target NuoDB database It loads data into the target NuoDB database It dumps data from the source database Let’s see how we can migrate our data from SQL Server to NuoDB using a simple three-step approach. But before we do that we will create a sample database in MSSQL and later we will migrate the same database to NuoDB: Setup Step 1: Build a sample data CREATE DATABASE [Test]; CREATE TABLE [Department]( [DepartmentID] [smallint] NOT NULL, [Name] VARCHAR(100) NOT NULL, [GroupName] VARCHAR(100) NOT NULL, [ModifiedDate] [datetime] NOT NULL, CONSTRAINT [PK_Department_DepartmentID] PRIMARY KEY CLUSTERED ( [DepartmentID] ASC ) ) ON [PRIMARY]; INSERT INTO Department SELECT * FROM AdventureWorks2012.HumanResources.Department; Note that I am using the SQL Server AdventureWorks database to build this sample table but you can build this sample table any way you prefer. Setup Step 2: Install Java 64 bit Before you can begin the migration process to NuoDB, make sure you have 64-bit Java installed on your computer. This is due to the fact that the NuoDB Migrator tool is built in Java. You can download 64-bit Java for Windows, Mac OSX, or Linux from the following link: http://java.com/en/download/manual.jsp. One more thing to remember is that you make sure that the path in your environment settings is set to your JAVA_HOME directory or else the tool will not work. Here is how you can do it: Go to My Computer >> Right Click >> Select Properties >> Click on Advanced System Settings >> Click on Environment Variables >> Click on New and enter the following values. Variable Name: JAVA_HOME Variable Value: C:\Program Files\Java\jre7 Make sure you enter your Java installation directory in the Variable Value field. Setup Step 3: Install JDBC driver for SQL Server. There are two JDBC drivers available for SQL Server.  Select the one you prefer to use by following one of the two links below: Microsoft JDBC Driver jTDS JDBC Driver In this example we will be using jTDS JDBC driver. Once you download the driver, move the driver to your NuoDB installation folder. In my case, I have moved the JAR file of the driver into the C:\Program Files\NuoDB\tools\migrator\jar folder as this is my NuoDB installation directory. Now we are all set to start the three-step migration process from SQL Server to NuoDB: Migration Step 1: NuoDB Schema Generation Here is the command I use to generate a schema of my SQL Server Database in NuoDB. First I go to the folder C:\Program Files\NuoDB\tools\migrator\bin and execute the nuodb-migrator.bat file. Note that my database name is ‘test’. Additionally my username and password is also ‘test’. You can see that my SQL Server database is running on my localhost on port 1433. Additionally, the schema of the table is ‘dbo’. nuodb-migrator schema –source.driver=net.sourceforge.jtds.jdbc.Driver –source.url=jdbc:jtds:sqlserver://localhost:1433/ –source.username=test –source.password=test –source.catalog=test –source.schema=dbo –output.path=/tmp/schema.sql The above script will generate a schema of all my SQL Server tables and will put it in the folder C:\tmp\schema.sql . You can open the schema.sql file and execute this file directly in your NuoDB instance. You can follow the link here to see how you can execute the SQL script in NuoDB. Please note that if you have not yet created the schema in the NuoDB database, you should create it before executing this step. Step 2: Generate the Dump File of the Data Once you have recreated your schema in NuoDB from SQL Server, the next step is very easy. Here we create a CSV format dump file, which will contain all the data from all the tables from the SQL Server database. The command to do so is very similar to the above command. Be aware that this step may take a bit of time based on your database size. nuodb-migrator dump –source.driver=net.sourceforge.jtds.jdbc.Driver –source.url=jdbc:jtds:sqlserver://localhost:1433/ –source.username=test –source.password=test –source.catalog=test –source.schema=dbo –output.type=csv –output.path=/tmp/dump.cat Once the above command is successfully executed you can find your CSV file in the C:\tmp\ folder. However, you do not have to do anything manually. The third and final step will take care of completing the migration process. Migration Step 3: Load the Data into NuoDB After building schema and taking a dump of the data, the very next step is essential and crucial. It will take the CSV file and load it into the NuoDB database. nuodb-migrator load –target.url=jdbc:com.nuodb://localhost:48004/mytest –target.schema=dbo –target.username=test –target.password=test –input.path=/tmp/dump.cat Please note that in the above script we are now targeting the NuoDB database, which we have already created with the name of “MyTest”. If the database does not exist, create it manually before executing the above script. I have kept the username and password as “test”, but please make sure that you create a more secure password for your database for security reasons. Voila!  You’re Done That’s it. You are done. It took 3 setup and 3 migration steps to migrate your SQL Server database to NuoDB.  You can now start exploring the database and build excellent, scale-out applications. In this blog post, I have done my best to come up with simple and easy process, which you can follow to migrate your app from SQL Server to NuoDB. Download NuoDB I strongly encourage you to download NuoDB and go through my 3-step migration tutorial from SQL Server to NuoDB. Additionally here are two very important blog post from NuoDB CTO Seth Proctor. He has written excellent blog posts on the concept of the Administrative Domains. NuoDB has this concept of an Administrative Domain, which is a collection of hosts that can run one or multiple databases.  Each database has its own TEs and SMs, but all are managed within the Admin Console for that particular domain. http://www.nuodb.com/techblog/2013/03/11/getting-started-provisioning-a-domain/ http://www.nuodb.com/techblog/2013/03/14/getting-started-running-a-database/ Reference: Pinal Dave (http://blog.sqlauthority.com) Filed under: Big Data, PostADay, SQL, SQL Authority, SQL Query, SQL Server, SQL Tips and Tricks, T SQL, Technology Tagged: NuoDB

• Fix: SqlDeploy Task Fails with NullReferenceException at ExtractPassword

  Still working on getting a TeamCity build working (see my last post).  Latest exception is: C:\Program Files\MSBuild\Microsoft\VisualStudio\v9.0\TeamData\Microsoft.Data.Schema.SqlTasks.targets(120, 5): error MSB4018: The "SqlDeployTask" task failed unexpectedly. System.NullReferenceException: Object reference not set to an instance of an object. at Microsoft.Data.Schema.Common.ConnectionStringPersistence.ExtractPassword(String partialConnection, String dbProvider) at Microsoft.Data.Schema.Common.ConnectionStringPersistence.RetrieveFullConnection(String partialConnection, String provider, Boolean presentUI, String password) at Microsoft.Data.Schema.Sql.Build.SqlDeployment.ConfigureConnectionString(String connectionString, String databaseName) at Microsoft.Data.Schema.Sql.Build.SqlDeployment.OnBuildConnectionString(String partialConnectionString, String databaseName) at Microsoft.Data.Schema.Build.Deployment.FinishInitialize(String targetConnectionString) at Microsoft.Data.Schema.Build.Deployment.Initialize(FileInfo sourceDbSchemaFile, ErrorManager errors, String targetConnectionString) at Microsoft.Data.Schema.Build.DeploymentConstructor.ConstructServiceImplementation() at Microsoft.Data.Schema.Extensibility.ServiceConstructor'1.ConstructService() at Microsoft.Data.Schema.Tasks.DBDeployTask.Execute() at Microsoft.Build.BuildEngine.TaskEngine.ExecuteInstantiatedTask(EngineProxy engineProxy, ItemBucket bucket, TaskExecutionMode howToExecuteTask, ITask task, Boolean& taskResult)   This time searching yielded some good stuff, including this thread that talks about how to resolve this via permissions.  The short answer is that the account that your build server runs under needs to have the necessary permissions in SQL Server.  Youll need to create a Login and then ensure at least the minimum rights are configured as described here: Required Permissions in Database Edition Alternately, you can just make your buildserver account an admin on the database (which is probably running on the same machine anyway) and at that point it should be able to do whatever it needs to. If youre certain the account has the necessary permissions, but youre still getting the error, the problem may be that the account has never logged into the build server.  In this case, there wont be any entry in the HKCU hive in the registry, which the system is checking for permissions (see this thread).  The solution in this case is quite simple: log into the machine (once is enough) with the build server account.  Then, open Visual Studio (thanks Brendan for the answer in this thread). Summary Make sure the build service account has the necessary database permissions Make sure the account has logged into the server so it has the necessary registry hive info Make sure the account has run Visual Studio at least once so its settings are established In my case I went through all 3 of these steps before I resolved the problem. 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.

In fact i can download the file from the browser without problems. There's an option to specify a proxy to wsdl2java or someone has resolved this issue ? For the moment i've downloaded the xsd, added it to the project and changed the wsdl to include the relative file (instead of the remote one) , but i'd prefer to avoid this , because the file is a third party service wsdl. thank you in advance for any hint Stefano

• WebDriver with firefox-x11 on Mac

  - by binil

  I am trying to run a headless test for a web application using WebDriver on Mac OS X 10.6.3. My plan is to run firefox-x11 with Xvfb, but WebDriver is unable to launch firefox-x11. My code is: System.setProperty("webdriver.firefox.bin", "/opt/local/bin/firefox-x11-devel-standalone"); WebDriver browser = new FirefoxDriver(); try { browser.get("http://google.com"); } finally { browser.close(); } but this fails with: org.openqa.selenium.WebDriverException: Unable to start firefox cleanly.

• NoPrimaryKeyException from DBUnit when loading a dataset into a databse

  - by Omar Kooheji

  I'm getting NoPrimaryKeyException when I try to run one of my unit tests which uses DBUnit. The datatable is created using Hibernate and is a join table between two classes mapping a many to many relationship. The annotations that define the relationship are as follows: @Override @ManyToMany @JoinTable(name="offset_file_offset_entries", joinColumns={@JoinColumn(name="offset_entry_id")},inverseJoinColumns={@JoinColumn(name="file_description_id")}) public List<OffsetEntry> getOffsets() { The other entries in in the XML file I'm using to define the dataset seem to work fine but not the join table. I get the following exception: org.dbunit.dataset.NoPrimaryKeyException: offset_file_offset_entries at org.dbunit.operation.UpdateOperation.getOperationData(UpdateOperation.java:72) at org.dbunit.operation.RefreshOperation$UpdateRowOperation.<init>(RefreshOperation.java:266) at org.dbunit.operation.RefreshOperation.createUpdateOperation(RefreshOperation.java:142) at org.dbunit.operation.RefreshOperation.execute(RefreshOperation.java:100) at org.dbunit.ext.mssql.InsertIdentityOperation.execute(InsertIdentityOperation.java:217) at uk.co.sabio.obscheduler.application.dao.AbstractBaseDatabaseTest.setUp(AbstractBaseDatabaseTest.java:57) at org.springframework.test.context.junit38.AbstractJUnit38SpringContextTests.runManaged(AbstractJUnit38SpringContextTests.java:332) at org.springframework.test.context.junit38.AbstractJUnit38SpringContextTests.access$0(AbstractJUnit38SpringContextTests.java:326) at org.springframework.test.context.junit38.AbstractJUnit38SpringContextTests$1.run(AbstractJUnit38SpringContextTests.java:216) at org.springframework.test.context.junit38.AbstractJUnit38SpringContextTests.runTest(AbstractJUnit38SpringContextTests.java:296) at org.springframework.test.context.junit38.AbstractJUnit38SpringContextTests.runTestTimed(AbstractJUnit38SpringContextTests.java:253) at org.springframework.test.context.junit38.AbstractJUnit38SpringContextTests.runBare(AbstractJUnit38SpringContextTests.java:213) at junit.framework.TestResult$1.protect(TestResult.java:110) at junit.framework.TestResult.runProtected(TestResult.java:128) at junit.framework.TestResult.run(TestResult.java:113) at junit.framework.TestCase.run(TestCase.java:124) at junit.framework.TestSuite.runTest(TestSuite.java:232) at junit.framework.TestSuite.run(TestSuite.java:227) at org.junit.internal.runners.JUnit38ClassRunner.run(JUnit38ClassRunner.java:83) at org.eclipse.jdt.internal.junit4.runner.JUnit4TestReference.run(JUnit4TestReference.java:46) at org.eclipse.jdt.internal.junit.runner.TestExecution.run(TestExecution.java:38) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:467) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:683) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:390) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:197) the Dataset entry in question looks like this: <offset_file_offset_entries offset_entry_id="1" file_description_id="1" /> And matches up with the database which has both fields as primary keys (The Databse is MS SQL Server if that helps) There are corresponding entries in the two tables being Joined defined in the following xml: <dataset> <file_description file_path="src/test/resources/" file_pattern=".txt" file_description_id="1"/> <offset_file_description file_description_id="1"/> <offset_entries offset_entry_id="1" field_name="Field1" field_length="10" start_index="0"/> <offset_file_offset_entries offset_entry_id="1" file_description_id="1" /> </dataset> Do I have to define the primary keys in the hibernate annotations? If so How do I do so? do I have to change the way I define my dataset to imply that the two columns are a joint primary key? I'm not very proficient with hibernate or DBUnit for that matter and I'm at my wits end so any assistance would be really appreciated.

• Why am I getting org.xml.sax.SAXException for this block of XML?

  - by drachenstern

  I've anonymised a bit of this. Hopefully it doesn't detract from the useful message. stringARRAY is where I think I'm getting thrown at, but I'm not sure, so if I'm looking at the wrong place, lemme know. From the WSDL <xsd:element name="LongishOpName"> <xsd:complexType> <xsd:sequence> <xsd:element maxOccurs="unbounded" name="stringARRAY" type="xsd:string" /> <xsd:element name="stringfield1" type="xsd:string" /> <xsd:element name="stringfield2" type="xsd:string" /> </xsd:sequence> </xsd:complexType> </xsd:element> Actual method call looks like this: string originalValue = "some useful value"; string[] usefulName1 = new[] { originalValue }; service.response[] responses = server.LongishOpName( usefulName1, someString1, someString2 ); And it generates this XML to the server (Thanks to Fiddler2): <?xml version="1.0" encoding="utf-8"?> <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <soap:Body> <LongishOpName xmlns="http://appropriate-namespace"> <stringARRAY>114003</stringARRAY> <stringfield1>a string</stringfield1> <stringfield2>a string</stringfield2> </LongishOpName> </soap:Body> </soap:Envelope> To which I get this response <?xml version="1.0" encoding="utf-8"?> <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <soapenv:Body> <soapenv:Fault> <faultcode>soapenv:Server.userException</faultcode> <faultstring>org.xml.sax.SAXException: Found character data inside an array element while deserializing</faultstring> <detail> <ns1:hostname xmlns:ns1="http://xml.apache.org/axis/">SERVERNAME</ns1:hostname> </detail> </soapenv:Fault> </soapenv:Body> </soapenv:Envelope> Is my soap message actually coming out malformed? (yes I am using the ASP.NET web references to do all the lifting, I'm not generating by hand) Should I be doing something different? Do I just need to go home and sleep on it and tomorrow everything will "just work"?

• JBOSS 7 encoding not working as expected

  - by Fofole

  I had problems with my listgrids not showing diacritcs corectly and I found out that when I inserted from java into the db the values where already bugged. A post here helped and I changed my project properties - Text encoding - other - UTF-8 and this fixed my problem. Thing is this only fixes my problem locally. What I need to do is on my Jboss server also set the encoding somehow. This is what I put in my configuration file: <?xml version='1.0' encoding='UTF-8'?> <server name="vali-ubuntu" xmlns="urn:jboss:domain:1.0"> extensions> extension module="org.jboss.as.clustering.infinispan"/> extension module="org.jboss.as.connector"/> extension module="org.jboss.as.deployment-scanner"/> extension module="org.jboss.as.ee"/> extension module="org.jboss.as.ejb3"/> extension module="org.jboss.as.jaxrs"/> extension module="org.jboss.as.jmx"/> extension module="org.jboss.as.logging"/> extension module="org.jboss.as.naming"/> extension module="org.jboss.as.osgi"/> extension module="org.jboss.as.remoting"/> extension module="org.jboss.as.sar"/> extension module="org.jboss.as.security"/> extension module="org.jboss.as.threads"/> extension module="org.jboss.as.transactions"/> extension module="org.jboss.as.web"/> extension module="org.jboss.as.weld"/> /extensions> system-properties> property name="org.apache.catalina.connector.URI_ENCODING" value="UTF-8"/> property name="org.apache.catalina.connector.USE_BODY_ENCODING_FOR_QUERY_STRING" value="tru e"/> /system-properties> //..... This doesn't work so maybe I need to add something else. I tried everything I could find with no succes so any help is appreciated. Thanks. EDIT:From what I read, this will work only in jboss 7.1.0 beta 1 or highier. (URIEncoding) and I use JBoss 7.0.2 so I need a replacement for 7.0.2

• How to create an entity with a composite primary key containing a generated value.

  - by David

  Using Hibernate + annotations, I'm trying to do the following: Two entities, Entity1 and Entity2. Entity1 contains a simple generated value primary key. Entity2 primary key is composed by a simple generated value + the id of entity one (with a many to one relationship) Unfortunately, I can't make it work. Here is an excerpt of the code: @Entity public class Entity1 { @Id @GeneratedValue private Long id; private String name; ... } @Entity public class Entity2 { @EmbeddedId private Entity2PK pk = new Entity2PK(); private String miscData; ... } @Embeddable public class Entity2PK implements Serializable { @GeneratedValue private Long id; @ManyToOne private Entity1 entity; } void test() { Entity1 e1 = new Entity1(); e1.setName("nameE1"); Entity2 e2 = new Entity2(); e2.setEntity1(e1); e2.setMiscData("test"); Transaction transaction = session.getTransaction(); try { transaction.begin(); session.save(e1); session.save(e2); transaction.commit(); } catch (Exception e) { transaction.rollback(); } finally { session.close(); } } When I run the test method I get the following errors: Hibernate: insert into Entity1 (id, name) values (null, ?)

• Ubuntu 10.04 not detecting multiple monitors

  - by user28837

  I have 2 graphics cards, the output from the lspci: 01:00.0 VGA compatible controller: ATI Technologies Inc RV770 [Radeon HD 4850] 02:00.0 VGA compatible controller: ATI Technologies Inc RV710 [Radeon HD 4350] I have one monitor connected to the 4850 and 2 connected to the 4350. However when I go into System Preferences Monitors the only monitor shown is the one connected to the 4850. Is there something I need to enable for it to be able to use the other card? How do I get this to work. Thanks.

• Deploying war files in tomcat6

  - by user3215

  I am using tomcat5.5 for a long on ubuntu servers 8.10 and 9.10 and '/usr/share/tomcat/webapps/' is the path where I place my .war files and access them on the browser over network. On a sytem I've installed tomcat6 and I'm failing to find that where do I place my .war file of tomcat6's webapps. I checked deploying war under /var/lib/tomcat6/webapps/ and the war file is extracted and I think this should be the location but I could not access the page when I tried http://serverip:8080/myapp. I could access the default page properly when I navigate to http://serverip:8080. The same war file is working fine on tomcat servers which were not installed from apt repository.

• How do I load tmx files with Slick2d?

  - by mbreen

  I just started using Slick2D and learned how simple it is to load in a tilemap and display it. I tried atleast a dozen different tmx files from numerous examples to see if it was the actual file that was corrupted. Everytime I get this error: Exception in thread "main" java.lang.RuntimeException: Resource not found: data/maps/desert.tmx at org.newdawn.slick.util.ResourceLoader.getResourceAsStream(ResourceLoader.java:69) at org.newdawn.slick.tiled.TiledMap.<init>(TiledMap.java:101) at game.Game.init(Game.java:17) at game.Tunneler.initStatesList(Tunneler.java:37) at org.newdawn.slick.state.StateBasedGame.init(StateBasedGame.java:164) at org.newdawn.slick.AppGameContainer.setup(AppGameContainer.java:390) at org.newdawn.slick.AppGameContainer.start(AppGameContainer.java:314) at game.Tunneler.main(Tunneler.java:29) Here is my Game class: package game; import org.newdawn.slick.GameContainer; import org.newdawn.slick.Graphics; import org.newdawn.slick.SlickException; import org.newdawn.slick.state.BasicGameState; import org.newdawn.slick.state.StateBasedGame; import org.newdawn.slick.tiled.TiledMap; public class Game extends BasicGameState{ private int stateID = -1; private TiledMap map = null; public Game(int stateID){ this.stateID = stateID; } public void init(GameContainer container, StateBasedGame game) throws SlickException{ map = new TiledMap("data/maps/desert.tmx","maps");//ERROR } public void render(GameContainer container, StateBasedGame game, Graphics g) throws SlickException{ //map.render(0,0); } public void update(GameContainer container, StateBasedGame game, int delta) throws SlickException{ } public int getID(){return stateID;} } I've tried to see if anyone else has had similar problems but haven't turned up anything. I am able to load other files, so I don't believe it's a compiler issue. My menu class can load images and display them just fine. Also, the filepath is correct. Please let me know if you have any pointers that might help me sort this out.

• Updating Ubuntu server from 8.10 to 10.04

  - by Ward

  I have a VPS that has Ubuntu 8.10 Server Edition installed on it and I would like to upgrade it to 10.04. What would be the correct way of doing this? I only have ssh access to it and a "Start/Shutdown VPS" in the client panel of the vendor. In other words, I do not have physical access to it. Also worth noting is that I apparently cannot install programs any more since the sources (osuosl.org ?) are not online. Not the ones this server has set anyway. # apt-get update Ign http://ubuntu.osuosl.org intrepid Release.gpg Ign http://ubuntu.osuosl.org intrepid/main Translation-en_US Ign http://ubuntu.osuosl.org intrepid/universe Translation-en_US Ign http://ubuntu.osuosl.org intrepid Release Ign http://ubuntu.osuosl.org intrepid/main Packages Ign http://ubuntu.osuosl.org intrepid/universe Packages Err http://ubuntu.osuosl.org intrepid/main Packages 404 Not Found Err http://ubuntu.osuosl.org intrepid/universe Packages 404 Not Found W: Failed to fetch http://ubuntu.osuosl.org/ubuntu/dists/intrepid/main/binary-amd64/Packages.gz 404 Not Found W: Failed to fetch http://ubuntu.osuosl.org/ubuntu/dists/intrepid/universe/binary-amd64/Packages.gz 404 Not Found E: Some index files failed to download, they have been ignored, or old ones used instead.

• Unable to import Maven project into IntelliJ IDEA

  - by del

  I'm having problems importing any Maven projects into IntelliJ IDEA. I create an empty Maven project like this: $ mvn archetype:generate -DgroupId=com.mycompany.app -DartifactId=my-app -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false Then I try to open the project in IDEA (File Open Project, then choose the pom.xml).

• Configuring ant to run unit tests. Where should libraries be? How should classpath be configured? av

  - by chillitom

  Hi All, I'm trying to run my junit tests using ant. The tests are kicked off using a JUnit 4 test suite. If I run this direct from Eclipse the tests complete without error. However if I run it from ant then many of the tests fail with this error repeated over and over until the junit task crashes. [junit] java.util.zip.ZipException: error in opening zip file [junit] at java.util.zip.ZipFile.open(Native Method) [junit] at java.util.zip.ZipFile.(ZipFile.java:114) [junit] at java.util.zip.ZipFile.(ZipFile.java:131) [junit] at org.apache.tools.ant.AntClassLoader.getResourceURL(AntClassLoader.java:1028) [junit] at org.apache.tools.ant.AntClassLoader$ResourceEnumeration.findNextResource(AntClassLoader.java:147) [junit] at org.apache.tools.ant.AntClassLoader$ResourceEnumeration.nextElement(AntClassLoader.java:130) [junit] at org.apache.tools.ant.util.CollectionUtils$CompoundEnumeration.nextElement(CollectionUtils.java:198) [junit] at sun.misc.CompoundEnumeration.nextElement(CompoundEnumeration.java:43) [junit] at org.apache.tools.ant.taskdefs.optional.junit.JUnitTask.checkForkedPath(JUnitTask.java:1128) [junit] at org.apache.tools.ant.taskdefs.optional.junit.JUnitTask.executeAsForked(JUnitTask.java:1013) [junit] at org.apache.tools.ant.taskdefs.optional.junit.JUnitTask.execute(JUnitTask.java:834) [junit] at org.apache.tools.ant.taskdefs.optional.junit.JUnitTask.executeOrQueue(JUnitTask.java:1785) [junit] at org.apache.tools.ant.taskdefs.optional.junit.JUnitTask.execute(JUnitTask.java:785) [junit] at org.apache.tools.ant.UnknownElement.execute(UnknownElement.java:288) [junit] at sun.reflect.GeneratedMethodAccessor1.invoke(Unknown Source) [junit] at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) [junit] at java.lang.reflect.Method.invoke(Method.java:597) [junit] at org.apache.tools.ant.dispatch.DispatchUtils.execute(DispatchUtils.java:106) [junit] at org.apache.tools.ant.Task.perform(Task.java:348) [junit] at org.apache.tools.ant.Target.execute(Target.java:357) [junit] at org.apache.tools.ant.Target.performTasks(Target.java:385) [junit] at org.apache.tools.ant.Project.executeSortedTargets(Project.java:1337) [junit] at org.apache.tools.ant.Project.executeTarget(Project.java:1306) [junit] at org.apache.tools.ant.helper.DefaultExecutor.executeTargets(DefaultExecutor.java:41) [junit] at org.apache.tools.ant.Project.executeTargets(Project.java:1189) [junit] at org.apache.tools.ant.Main.runBuild(Main.java:758) [junit] at org.apache.tools.ant.Main.startAnt(Main.java:217) [junit] at org.apache.tools.ant.launch.Launcher.run(Launcher.java:257) [junit] at org.apache.tools.ant.launch.Launcher.main(Launcher.java:104) my test running task is as follows: <target name="run-junit-tests" depends="compile-tests,clean-results"> <mkdir dir="${test.results.dir}"/> <junit failureproperty="tests.failed" fork="true" showoutput="yes" includeantruntime="false"> <classpath refid="test.run.path" /> <formatter type="xml" /> <test name="project.AllTests" todir="${basedir}/test-results" /> </junit> <fail if="tests.failed" message="Unit tests failed"/> </target> I've verified that the classpath contains the following as well as all of the program code and libraries: ant-junit.jar ant-launcher.jar ant.jar easymock.jar easymockclassextension.jar junit-4.4.jar I've tried debugging to find out which ZipFile it is trying to open with no luck, I've tried toggling includeantruntime and fork and i've tried running ant with ant -lib test/libs where test/libs contains the ant and junit libraries. Any info about what causes this exception or how you've configured ant to successfully run unit tests is gratefully received. ant 1.7.1 (ubuntu), java 1.6.0_10, junit 4.4 Thanks. Update - Fixed Found my problem. I had included my classes directory in my path using a fileset as opposed to a pathelement this was causing .class files to be opened as ZipFiles which of course threw an exception.

• Hibernate : Foreign key constraint violation problem

  - by Vinze

  I have a com.mysql.jdbc.exceptions.MySQLIntegrityConstraintViolationException in my code (using Hibernate and Spring) and I can't figure why. My entities are Corpus and Semspace and there's a many-to-one relation from Semspace to Corpus as defined in my hibernate mapping configuration : <class name="xxx.entities.Semspace" table="Semspace" lazy="false" batch-size="30"> <id name="id" column="idSemspace" type="java.lang.Integer" unsaved-value="null"> <generator class="identity"/> </id> <property name="name" column="name" type="java.lang.String" not-null="true" unique="true" /> <many-to-one name="corpus" class="xxx.entities.Corpus" column="idCorpus" insert="false" update="false" /> [...] </class> <class name="xxx.entities.Corpus" table="Corpus" lazy="false" batch-size="30"> <id name="id" column="idCorpus" type="java.lang.Integer" unsaved-value="null"> <generator class="identity"/> </id> <property name="name" column="name" type="java.lang.String" not-null="true" unique="true" /> </class> And the Java code generating the exception is : Corpus corpus = Spring.getCorpusDAO().getCorpusById(corpusId); Semspace semspace = new Semspace(); semspace.setCorpus(corpus); semspace.setName(name); Spring.getSemspaceDAO().save(semspace); I checked and the corpus variable is not null (so it is in database as retrieved with the DAO) The full exception is : com.mysql.jdbc.exceptions.MySQLIntegrityConstraintViolationException: Cannot add or update a child row: a foreign key constraint fails (`xxx/Semspace`, CONSTRAINT `FK4D6019AB6556109` FOREIGN KEY (`idCorpus`) REFERENCES `Corpus` (`idCorpus`)) at com.mysql.jdbc.SQLError.createSQLException(SQLError.java:931) at com.mysql.jdbc.MysqlIO.checkErrorPacket(MysqlIO.java:2941) at com.mysql.jdbc.MysqlIO.sendCommand(MysqlIO.java:1623) at com.mysql.jdbc.MysqlIO.sqlQueryDirect(MysqlIO.java:1715) at com.mysql.jdbc.Connection.execSQL(Connection.java:3249) at com.mysql.jdbc.PreparedStatement.executeInternal(PreparedStatement.java:1268) at com.mysql.jdbc.PreparedStatement.executeUpdate(PreparedStatement.java:1541) at com.mysql.jdbc.PreparedStatement.executeUpdate(PreparedStatement.java:1455) at com.mysql.jdbc.PreparedStatement.executeUpdate(PreparedStatement.java:1440) at org.apache.commons.dbcp.DelegatingPreparedStatement.executeUpdate(DelegatingPreparedStatement.java:102) at org.hibernate.id.IdentityGenerator$GetGeneratedKeysDelegate.executeAndExtract(IdentityGenerator.java:73) at org.hibernate.id.insert.AbstractReturningDelegate.performInsert(AbstractReturningDelegate.java:33) at org.hibernate.persister.entity.AbstractEntityPersister.insert(AbstractEntityPersister.java:2158) at org.hibernate.persister.entity.AbstractEntityPersister.insert(AbstractEntityPersister.java:2638) at org.hibernate.action.EntityIdentityInsertAction.execute(EntityIdentityInsertAction.java:48) at org.hibernate.engine.ActionQueue.execute(ActionQueue.java:250) at org.hibernate.event.def.AbstractSaveEventListener.performSaveOrReplicate(AbstractSaveEventListener.java:298) at org.hibernate.event.def.AbstractSaveEventListener.performSave(AbstractSaveEventListener.java:181) at org.hibernate.event.def.AbstractSaveEventListener.saveWithGeneratedId(AbstractSaveEventListener.java:107) at org.hibernate.event.def.DefaultSaveOrUpdateEventListener.saveWithGeneratedOrRequestedId(DefaultSaveOrUpdateEventListener.java:187) at org.hibernate.event.def.DefaultSaveEventListener.saveWithGeneratedOrRequestedId(DefaultSaveEventListener.java:33) at org.hibernate.event.def.DefaultSaveOrUpdateEventListener.entityIsTransient(DefaultSaveOrUpdateEventListener.java:172) at org.hibernate.event.def.DefaultSaveEventListener.performSaveOrUpdate(DefaultSaveEventListener.java:27) at org.hibernate.event.def.DefaultSaveOrUpdateEventListener.onSaveOrUpdate(DefaultSaveOrUpdateEventListener.java:70) at org.hibernate.impl.SessionImpl.fireSave(SessionImpl.java:535) at org.hibernate.impl.SessionImpl.save(SessionImpl.java:523) at org.hibernate.impl.SessionImpl.save(SessionImpl.java:519) at org.springframework.orm.hibernate3.HibernateTemplate$12.doInHibernate(HibernateTemplate.java:642) at org.springframework.orm.hibernate3.HibernateTemplate.execute(HibernateTemplate.java:373) at org.springframework.orm.hibernate3.HibernateTemplate.save(HibernateTemplate.java:639) at xxx.dao.impl.AbstractDAO.save(AbstractDAO.java:26) at org.apache.jsp.functions.semspaceManagement_jsp._jspService(semspaceManagement_jsp.java:218) [...] The foreign key constraint has been created (and added to database) by hibernate and I don't see where the constraint can be violated. The table are innodb and I tried to drop all tables and recreate it the problem remains... EDIT : Well I think I have a start of answer... I change the log level of hibernate to DEBUG and before it crash I have the following log insert into Semspace (name, [...]) values (?, [...]) So it looks like it does not try to insert the idCorpus and as it is not null it uses the default value "0" which does not refers to an existing entry in Corpus table...

• Using JUnit with App Engine and Eclipse

  - by Mark M

  I am having trouble setting up JUnit with App Engine in Eclipse. I have JUnit set up correctly, that is, I can run tests that don't involve the datastore or other services. However, when I try to use the datastore in my tests they fail. The code I am trying right now is from the App Engine site (see below): http://code.google.com/appengine/docs/java/tools/localunittesting.html#Running_Tests So far I have added the external JAR (using Eclipse) appengine-testing.jar. But when I run the tests I get the exception below. So, I am clearly not understanding the instructions to enable the services from the web page mentioned above. Can someone clear up the steps needed to make the App Engine services available in Eclipse? java.lang.NoClassDefFoundError: com/google/appengine/api/datastore/dev/LocalDatastoreService at com.google.appengine.tools.development.testing.LocalDatastoreServiceTestConfig.tearDown(LocalDatastoreServiceTestConfig.java:138) at com.google.appengine.tools.development.testing.LocalServiceTestHelper.tearDown(LocalServiceTestHelper.java:254) at com.cooperconrad.server.MemberTest.tearDown(MemberTest.java:28) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.junit.runners.model.FrameworkMethod$1.runReflectiveCall(FrameworkMethod.java:44) at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:15) at org.junit.runners.model.FrameworkMethod.invokeExplosively(FrameworkMethod.java:41) at org.junit.internal.runners.statements.RunAfters.evaluate(RunAfters.java:37) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:73) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:46) at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:180) at org.junit.runners.ParentRunner.access$000(ParentRunner.java:41) at org.junit.runners.ParentRunner$1.evaluate(ParentRunner.java:173) at org.junit.internal.runners.statements.RunBefores.evaluate(RunBefores.java:28) at org.junit.internal.runners.statements.RunAfters.evaluate(RunAfters.java:31) at org.junit.runners.ParentRunner.run(ParentRunner.java:220) at org.eclipse.jdt.internal.junit4.runner.JUnit4TestReference.run(JUnit4TestReference.java:46) at org.eclipse.jdt.internal.junit.runner.TestExecution.run(TestExecution.java:38) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:467) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:683) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:390) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:197) Caused by: java.lang.ClassNotFoundException: com.google.appengine.api.datastore.dev.LocalDatastoreService at java.net.URLClassLoader$1.run(URLClassLoader.java:202) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:190) at java.lang.ClassLoader.loadClass(ClassLoader.java:307) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301) at java.lang.ClassLoader.loadClass(ClassLoader.java:248) ... 25 more Here is the actual code (pretty much copied from the site): package com.example; import static org.junit.Assert.*; import org.junit.After; import org.junit.Before; import org.junit.Test; import com.google.appengine.api.datastore.DatastoreService; import com.google.appengine.api.datastore.DatastoreServiceFactory; import com.google.appengine.api.datastore.Entity; import com.google.appengine.api.datastore.Query; import com.google.appengine.tools.development.testing.LocalDatastoreServiceTestConfig; import com.google.appengine.tools.development.testing.LocalServiceTestHelper; public class MemberTest { private final LocalServiceTestHelper helper = new LocalServiceTestHelper(new LocalDatastoreServiceTestConfig()); @Before public void setUp() { helper.setUp(); } @After public void tearDown() { helper.tearDown(); } // run this test twice to prove we're not leaking any state across tests private void doTest() { DatastoreService ds = DatastoreServiceFactory.getDatastoreService(); assertEquals(0, ds.prepare(new Query("yam")).countEntities()); ds.put(new Entity("yam")); ds.put(new Entity("yam")); assertEquals(2, ds.prepare(new Query("yam")).countEntities()); } @Test public void testInsert1() { doTest(); } @Test public void testInsert2() { doTest(); } @Test public void foo() { assertEquals(4, 2 + 2); } }

When thrown nothing is painted. Another interesting thing is the timing of the throwing. I am unable to find any logical patern, as sometimes it is thrown as soon as I initiate the class and sometimes it needs more then five minutes. In addition to this, as far as I tested there is no single action that calls repaint() that triggers it or rather all do. I am new to Java and all the other exceptions had the class and row number of where they were thrown so I don't know what to do here. Any suggestions would be greatly appreciated. The code is enormous so I'll put just the paint method and if anything additional is needed please say so. @Override public void paint(Graphics g) { if(documentLoaded && showingOnScreen){ try{ rad = (int)(radInit+zoom*faktorRad); //max rad = 20 super.paint(g); Graphics2D g2d = (Graphics2D) g; paintElements(g2d); } catch(NullPointerException nulle){ } } } edit: There is no array in my class so i can't check any index. I think that this exception is thrown from a library I use, but it's a .jar file and I don't know how to open it.

• Remote EJB lookup issue with WebSphere 6.1

  - by marc dauncey

  I've seen this question asked before, but I've tried various solutions proposed, to no avail. Essentially, I have two EJB enterprise applications, that need to communicate with one another. The first is a web application, the second is a search server - they are located on different development servers, not in the same node, cell, or JVM, although they are on the same physical box. I'm doing the JNDI lookup via IIOP, and the URL I am using is as follows: iiop://searchserver:2819 In my hosts file, I've set searchserver to 127.0.0.1. The ports for my search server are bound to this hostname too. However, when the web app (that uses Spring btw) attempts to lookup the search EJB, it fails with the following error. This is driving me nuts, surely this kind of comms between the servers should be fairly simple to get working. I've checked the ports and they are correct. I note that the exception says the initial context is H00723Node03Cell/nodes/H00723Node03/servers/server1, name: ejb/com/hmv/dataaccess/ejb/hmvsearch/HMVSearchHome. This is the web apps server NOT the search server. Is this correct? How can I get Spring to use the right context?

I'm using JBoss Netty to handle simple http request and using MemCachedClient check existence of client ip in memcached. import org.jboss.netty.channel.ChannelHandler; import static org.jboss.netty.handler.codec.http.HttpHeaders.*; import static org.jboss.netty.handler.codec.http.HttpHeaders.Names.*; import static org.jboss.netty.handler.codec.http.HttpResponseStatus.*; import static org.jboss.netty.handler.codec.http.HttpVersion.*; import com.danga.MemCached.*; import java.util.List; import java.util.Map; import java.util.Map.Entry; import java.util.Set; import org.jboss.netty.buffer.ChannelBuffer; import org.jboss.netty.buffer.ChannelBuffers; import org.jboss.netty.channel.ChannelFuture; import org.jboss.netty.channel.ChannelFutureListener; import org.jboss.netty.channel.ChannelHandlerContext; import org.jboss.netty.channel.ExceptionEvent; import org.jboss.netty.channel.MessageEvent; import org.jboss.netty.channel.SimpleChannelUpstreamHandler; import org.jboss.netty.handler.codec.http.Cookie; import org.jboss.netty.handler.codec.http.CookieDecoder; import org.jboss.netty.handler.codec.http.CookieEncoder; import org.jboss.netty.handler.codec.http.DefaultHttpResponse; import org.jboss.netty.handler.codec.http.HttpChunk; import org.jboss.netty.handler.codec.http.HttpChunkTrailer; import org.jboss.netty.handler.codec.http.HttpRequest; import org.jboss.netty.handler.codec.http.HttpResponse; import org.jboss.netty.handler.codec.http.HttpResponseStatus; import org.jboss.netty.handler.codec.http.QueryStringDecoder; import org.jboss.netty.util.CharsetUtil; /** * @author <a href="http://www.jboss.org/netty/">The Netty Project</a> * @author Andy Taylor ([email protected]) * @author <a href="http://gleamynode.net/">Trustin Lee</a> * * @version $Rev: 2368 $, $Date: 2010-10-18 17:19:03 +0900 (Mon, 18 Oct 2010) $ */ @SuppressWarnings({"ALL"}) public class HttpRequestHandler extends SimpleChannelUpstreamHandler { private HttpRequest request; private boolean readingChunks; /** Buffer that stores the response content */ private final StringBuilder buf = new StringBuilder(); protected MemCachedClient mcc = new MemCachedClient(); private static SockIOPool poolInstance = null; static { // server list and weights String[] servers = { "lcalhost:11211" }; //Integer[] weights = { 3, 3, 2 }; Integer[] weights = {1}; // grab an instance of our connection pool SockIOPool pool = SockIOPool.getInstance(); // set the servers and the weights pool.setServers(servers); pool.setWeights(weights); // set some basic pool settings // 5 initial, 5 min, and 250 max conns // and set the max idle time for a conn // to 6 hours pool.setInitConn(5); pool.setMinConn(5); pool.setMaxConn(250); pool.setMaxIdle(21600000); //1000 * 60 * 60 * 6 // set the sleep for the maint thread // it will wake up every x seconds and // maintain the pool size pool.setMaintSleep(30); // set some TCP settings // disable nagle // set the read timeout to 3 secs // and don't set a connect timeout pool.setNagle(false); pool.setSocketTO(3000); pool.setSocketConnectTO(0); // initialize the connection pool pool.initialize(); // lets set some compression on for the client // compress anything larger than 64k //mcc.setCompressEnable(true); //mcc.setCompressThreshold(64 * 1024); } @Override public void messageReceived(ChannelHandlerContext ctx, MessageEvent e) throws Exception { HttpRequest request = this.request = (HttpRequest) e.getMessage(); if(mcc.get(request.getHeader("X-Real-Ip")) != null) { HttpResponse response = new DefaultHttpResponse(HTTP_1_1, OK); response.setHeader("X-Accel-Redirect", request.getUri()); ctx.getChannel().write(response).addListener(ChannelFutureListener.CLOSE); } else { sendError(ctx, NOT_FOUND); } } private void writeResponse(MessageEvent e) { // Decide whether to close the connection or not. boolean keepAlive = isKeepAlive(request); // Build the response object.

May be it's related to context in which mcc doesn't exist. Any help appreciated EDIT: Original code http://docs.jboss.org/netty/3.2/xref/org/jboss/netty/example/http/snoop/package-summary.html I've modified some parts to fit my needs.

• problem in subreport

  - by prabhudatta sahoo

  suppose i have 2 schema,i.e. fy0910 and fy1011.so when i see the report in schema fy0910 or in fy1011 i have to change every time the schema reference for the subreport,but when i see the report in the specific schema after setting the schema reference then there is no problem in subreport but when i go to another schema then again i have to change the schema reference for sub report.For your kind information there is absolutely no problem in main report.so plz give solution to me i will be thankful to u.

• ODI and OBIEE 11g Integration

  - by David Allan

  Here we will see some of the connectivity options to OBIEE 11g using the JDBC driver. You’ll see based upon some connection properties how the physical or presentation layers can be utilized. In the integrators guide for OBIEE 11g you will find a brief statement indicating that there actually is a JDBC driver for OBIEE. In OBIEE 11g its now possible to connect directly to the physical layer, Venkat has an informative post here on this topic. In ODI 11g the Oracle BI technology is shipped with the product along with KMs for reverse engineering, and using OBIEE models for a data source. When you install OBIEE in 11g a light weight demonstration application is preinstalled in the server, when you open this in the BI Administration tool we see the regular 3 panel view within the administration tool. To interrogate this system via JDBC (just like ODI does using the KMs) need a couple of things; the JDBC driver from OBIEE 11g, a java client program and the credentials. In my java client program I want to connect to the OBIEE system, when I connect I can interrogate what the JDBC driver presents for the metadata. The metadata projected via the JDBC connection’s DatabaseMetadata changes depending on whether the property NQ_SESSION.SELECTPHYSICAL is set when the java client connects. Let’s use the sample app to illustrate. I have a java client program here that will print out the tables in the DatabaseMetadata, it will also output the catalog and schema. For example if I execute without any special JDBC properties as follows; java -classpath .;%BIHOMEDIR%\clients\bijdbc.jar meta_jdbc oracle.bi.jdbc.AnaJdbcDriver jdbc:oraclebi://localhost:9703/ weblogic mypass Then I get the following returned representing the presentation layer, the sample I used is XML, and has no schema; Catalog Schema Table Sample Sales Lite null Base Facts Sample Sales Lite null Calculated Facts …     Sample Targets Lite null Base Facts …     Now if I execute with the only difference being the JDBC property NQ_SESSION.SELECTPHYSICAL with the value Yes, then I see a different set of values representing the physical layer in OBIEE; java -classpath .;%BIHOMEDIR%\clients\bijdbc.jar meta_jdbc oracle.bi.jdbc.AnaJdbcDriver jdbc:oraclebi://localhost:9703/ weblogic mypass NQ_SESSION.SELECTPHYSICAL=Yes The following is returned; Catalog Schema Table Sample App Lite Data null D01 Time Day Grain Sample App Lite Data null F10 Revenue Facts (Order grain) …     System DB (Update me)     …     If this was a database system such as Oracle, the catalog value would be the OBIEE database name and the schema would be the Oracle database schema. Other systems which have real catalog structure such as SQLServer would use its catalog value. Its this ‘Catalog’ and ‘Schema’ value that is important when integration OBIEE with ODI. For the demonstration application in OBIEE 11g, the following illustration shows how the information from OBIEE is related via the JDBC driver through to ODI. In the XML example above, within ODI’s physical schema definition on the right, we leave the schema blank since the XML data source has no schema. When I did this at first, I left the default value that ODI places in the Schema field since which was ‘<Undefined>’ (like image below) but this string is actually used in the RKM so ended up not finding any tables in this schema! Entering an empty string resolved this. Below we see a regular Oracle database example that has the database, schema, physical table structure, and how this is defined in ODI.   Remember back to the physical versus presentation layer usage when we passed the special property, well to do this in ODI, the data server has a panel for properties where you can define key/value pairs. So if you want to select physical objects from the OBIEE server, then you must set this property. An additional changed in ODI 11g is the OBIEE connection pool support, this has been implemented via a ‘Connection Pool’ flex field for the Oracle BI data server. So here you set the connection pool name from the OBIEE system that you specifically want to use and this is used by the Oracle BI to Oracle (DBLINK) LKM, so if you are using this you must set this flex field. Hopefully a useful insight into some of the mechanics of how this hangs together.

• The Difference Between .com, .net, .org and Why We’re About To See Many More Top-Level Domains

  - by Chris Hoffman

  .com, .net, .org and other website suffixes are known as “top-level domains” (TLDs). While we normally see only a few of these, there are hundreds of them – and there may be thousands more soon. Top-level domains are managed by the Internet Assigned Numbers Authority (IANA), which is run by the Internet Corporation for Assigned Names and Numbers (ICANN).
