  After a quick crash course Derby, run, create users, schemas, blunders by finding where derby.properties is going, etc. I have now it works using ClientDataSource and ClientXADataSource. It's only against localhost, which means little to your original question, but I am too wonr out/confused/scared to try to get the Derby settles everywhere and running on another server.

  So with a little Derby, what I discovered was that when usign the ' * DataSource ' class, you must specify the databaseName as an additional property. It does not appear to fall within the URL. I don't know why. The doc on the use of ClientDataSource is very thin in my humble OPINION. But after reading the error message, it seems to me that the databaseName has not been picked up from the URL, so I tried the approach of the property and the bingo! It worked.

  On our side, I then noticed in the console 'EM, that the "Test connection" button in the screen create only "seems to not work when property." I just filled in the fields, hit finish and then tested from the JDBC resources page resulting.

  Anyway, the best way for you to create the JDBC resource is probably to change the file data - sources.xml and add them manually.

  Here are the examples I used - note that I used a managed pool of datasource/connection both a native data source.

  < user native-data-source = "foo" password = 'bar '.
  URL = "jdbc:derby://localhost:1527 / wombat;" create = true ".
  Data-source-class = "org.apache.derby.jdbc.ClientXADataSource".
  JNDI-name = "jdbc/MyDerbyTest" name = "MyDerbyTest" >
  < property name = "databaseName" value = "wombat" / >
  < property name = value "createDatabase" = "true" / >
  < / native-data-source >

  And

  < connection-pool name = "DerbyCP_Foo" >
  <-factory connections
  factory-class = "org.apache.derby.jdbc.ClientXADataSource".
  user = 'foo '.
  password = 'bar '.
  URL = "jdbc:derby://localhost:1527 / wombat" >
  < property name = "databaseName" value = "wombat" / >
  < / factory connections >
  < / connection pool >

  < managed data source
  Connection-pool-name = "DerbyCP_Foo".
  JNDI-name = jdbc/derby/Foo"."
  name = "DerbyDS_Foo" / >

  Then I could run a test through the DS and it worked.

  Now, one thing that I've seen, but I have not worked through is that the default policy for the Derby network server only allows connections from localhost. I left as an exercise for the interested :-) reader develop and test. That I've demonstrated here, is that you can configure a ConnectionPool/ManagedDataSource and a NativeDataSource using the org.apache.derby.jdbc.ClientXADataSource class and make it work.

  Finally, I have my configured OC4J instance so that the derbyclient.jar is located in the applib directory and EM is configured so that it can see the contents of the directory by distorting its application.xml file - orion.

• connection pool

  HI the OBIEE Experts

  How many pools of connections you used in your project

  To get data from another schema, then what you must activate in the connection pool

  . Can we create multiple pools of connection under the object of a database

  
  

  Thanks in advance

  You seriously to come on the forum and posting simply questions of an interview questionnaire or a certification test?

  You have 4 threads right now with 2 different user accounts. I suggest that you stop this behavior. Start posting questions with a specific context and meaning. We only are here to get a job, that you should better start for your own good if you do not know the answers and even less here to help you cheat your way to certification.

• OBIEE 11 g RPD migration - how to automate the Connection Pool passwords changes in environments

  Hello gurus

  We have a situation in our client, where I am responsible for automating RPD Migrations in environments. In our current scenarios, (SID database) data source names and user names (schema name) are same in environments. The current process deploy us the RPD by EM then SPR online by using the administration tool and manually open update passwords in each connection pool (we have 9 pools of connections). There has been a lot of problems with this approach you can imagine (especial when do things the manual way).

  Can you please provide a better approach to automate this process in order to avoid human error.

  Thank you very much.

• Missing for DBAdapter cluster Weblogic Congfiguration outbound connection Pool entry

  Hello

  When I created an entry for outbound connection pool in DBAdapter weblogic console in a clustered (1-Admin server and servers managed by 2) environment and updated adapter DB, I have identified only input connection is updated in that plan a managed server and other server managed, it is not updated. For this reason, we are unable to access the data sources for some requests for the application.

  As a work-around if we plan. XML file to another server managed manually with update and DB adapter connection entry, we are able to find the entrance of connection for managed servers.

  Outside work around there at - it another solution to this problem so that I can add a connection adapter DB Console entry that will update the two plan files.

  Thank you and best regards,

  Can I propose to maintain the file plan of shared drive accessible from all nodes in the server, this will reduce the manual work.

• API - POST - REST VCO connection pool closing

  Hello

  I'm working on an automation scenario where I need a VCO A workflow to start another workflow VCO B using the VCO REST Plugin (1.0.2) on VCO 5.1.1.

  I did it with success while creating a multitude of REST and surgery REMAINS by using the appropriate workflow. However, my approach is a lot of static and I need to create REST operations on the fly. I have had a look at workflows Plugin and try to do the same thing in my workflow.

  However I am stuck with the error 'Connection Pool close' when you try to run the POST request.

  My approach is to store the host REMAINS as a static attribute with VCO configuration object and retrieve it from there. I can run GET operations without any problem with the owner, i.e.

  
  restRequest = restHost.createRequest (restType, restUrl, restContent);

  restResponse = restRequest.execute ();

  My problem is actually running a POST operation. I prepared the content in XML format, which is

  " <-xmlns = execution context" http://www.VMware.com/VCO "> "
  < Parameters >

  < name parameter = "param1" type = "string" >

  < string > 1 < / string >

  < / parameter >

  < name parameter = "param2" type = "string" >

  < string > value2 < / string >

  < / parameter >

  < / Parameter >

  < / execution context >

  and use the content type "application/xml". Earlier in my code, I run a query GET to retrieve my ID for workflow target to create a Url like this:

  flow of work/98c3b8ee-9569-4940-acc1-b8fbc2e64649 / executions.

  This is code that I use to make the POST while creating an operation of REST when needed and delete it later.

  
  var restOperation = new RESTOperation (System.nextUUID ());

  restOperation.method = restType;

  restOperation.urlTemplate = restUrl;

  restOperation.defaultContentType = restContentType;

  restHost.addOperation (restOperation);

  RESTHostManager.updateHost (restHost);

  inputParameters var = [];

  var restRequest = restOperation.createRequest (inputParameters, restContent);

  restRequest.contentType = restContentType;

  var restResponse = restRequest.execute ();

  restHost.removeOperation (restOperation.id);

  RESTHostManager.updateHost (restHost);

  My code does not work when calling for the lifting of restRequest.execute: ' InternalError: connection pool arrested "." If anyone else has tried a similar scenario or has any idea what I may be missing?

  Thank you

  Bernd

  Thanks chap - update the objects did the trick.

  In my case, that initially caused the problem travel of COULD happen. Of course store the restHost object in the configuration of VCO leads to an out-of-date version at run time. I'm now store the ID of restHost only. Then, copy the following code works:

  var restHostId is System.getModule("my.library").myGetConfigAttr ("Folder", "VCO", "restHostId");.

  var restHost = RESTHostManager.getHost (restHostId);

  If (restType == 'GET') {}
  try {}
  restRequest = restHost.createRequest (restType, restUrl, restContent);
  restResponse = restRequest.execute ();
  }
  catch (exp) {throw ("request REST to run: cannot run '" + restType + "' '" + restUrl + "' request-reason = '" + exp + "'") ;}}
  }
  else {}
  try {}
  var restOperation = new RESTOperation (System.nextUUID ());
  restOperation.method = restType;
  restOperation.urlTemplate = restUrl;
  restOperation.defaultContentType = restContentType;
   
  restHost.addOperation (restOperation);
  RESTHostManager.updateHost (restHost);
   
  restHost = RESTHostManager.getHost (restHost.id);
  restOperation = restHost.getOperation (restOperation.id);

  inputParameters var = [];
  var restRequest = restOperation.createRequest (inputParameters, restContent);
  restRequest.contentType = restContentType;

  var restResponse = restRequest.execute ();

  restHost.removeOperation (restOperation.id);
  RESTHostManager.updateHost (restHost);
  }
  catch (exp) {throw ("request REST to run: cannot run '" + restType + "' '" + restUrl + "' request-reason = '" + exp + "'") ;}}

• Pool table of event in the connection pool of 11g OIC for obiee 11g

  Hi all, I tried to use the event pool table using the OIC 11 g connection pool. A deleted event, but cache pool table records did not get purged after 60 minutes interval. Should we do addition together upwards to event pool table when you use oci 11g other that makes it active?

• the connection of WebLogic connection pool timeout issue too soon

  We are having a problem with the connection to weblogic pool. Our web application is based on the Spring Framework, deploy to Weblogic using the data source to connect to Oracle. We use a duration of 1 min and max setting of connection pool 15 on weblogic. But the problem that we face is that the pool does not manage any connection as a pool.

• WebLogic datasource County connection active more than the max connection pool

  Hi guys,.
  
  We will observe strange behavior on one of our WebLogic instances. A data source is set up with an initial and maximum of 50 capacity, and yet the source of data analysis, we see a number of active connections more of 50 years. In fact, it continues to rise up to 800, after which the database stops to deny connections (obviously).
  
  Why the maximum capacity of the connection pool is not respected?
  
  We lack WebLogic 10.3.5 and the connection pool is connected to an Oracle database using the driver oracle.jdbc.OracleDriver.
  
  Thank you!

  Yes, wire-PIN is documented to override your init-max because it takes
  a connection by running WebLogic threads. If your application also generates its own thread
  who get to pool connections, you have 800 (ugly) son, with a connection.
  This would indicate use suboptimal pool too, which is better to use in getting a connection, using
  and close the ASP, all in a single method call, if the connections are not kept for long periods
  by any thread.

• test of connection pool

  Hello
  When we created the connection pooling in the Administration tool, is possible to test it... aside from > tools > update all rows count...?
  Because it takes more time to test... especially in large data sets. is there a simple way to test if the connection pool configured correctly or not... ?
  Help would be appreciated...
  
  Thank you and best regards,
  Sri-Oracle.

  Yes, simply perform display data from a table that has a limited set of data
  OR
  Create a TEST table in the database with the smallest data set and use this TEST table to display data and to validate the CP parameter

• Connection pool with the OAS and the optimal value of min/max

  Hello world
  
  
  I have ", works with admin app to implement under oracle application server connection pool. The current value is min = 0, max = unlimited which I think means not implemented connection pool.
  
  Anyway I don't have a lot of information on connection pooling, I searched the forums, but I'm not able to find any useful information.
  
  
  My Manager would like to know what is the optimal value for min/max for the database, is there a specific formula or a tool that can help me on this issue?
  
  
  Thanks in advance.

  Hello

  It's a specific formula or a tool that can help me on this issue?

  The value that you specify for the number of connections and connections Min depends on a combination of factors, including the size and configuration of your database server and the type of the SQL operations that
  your application runs.

  For connection pooling,.
  First, check what is the value of 'process' located on the end of DB (for your current value, check v$ resource_limit at the end of db)...
  for example if the process is set to "1000", you cannot set the maximum value of the connection pool to the end server application above 1000 it will crash your database.

  now on the server side Application.
  As a best practice, set the maximum number of open connections and Minimum of connections open to the same value.

  For more details on connection pool and its settings.
  Check "Setting Up Data Sources - Performance Issues" of the link pdf below

• Global temporary Tables from Oracle and connection pooling

  When grouping, connection ('maintain connections' in cfadmin) is enabled. Oracle Global Temporary tables is screwed up. Bleeding of a page of data request to another because CF is reusing the same Oracle session over and over again.

  Is there a JDBC driver that will allow the use of global Temp Tables while having enabled connection pooling? 

  Other applications, such as Oracle Application Server servers, somehow allow the pooling and work together harmoniously TWG.

  If your temporary tables created with the default setting of validation remove lines, the cftransaction tag will help you.  Copy the following code:

  
  
  insert into t_dan_test values (1)
  
  
  Select * from t_dan_test
  
  
  
  Select * from t_dan_test

• RE: connection pool

  Hello
  
  I use Oracle database 11g on Win XP and if my OBIEE 10 g is also installed on the same PC from Win XP.
  
  My question is, when I do a connection pool in the physical layer through the administration tool,
  What will be my DATA SOURCE, the name of user and password?
  
  Currently, I have created a DATA SOURCE in Windows as
  
  Start-> Control Panel - > administration-> source-> system DSN data tools - > ADD-> my_oracle_db
  
  then named the data source, as many user/schema oracle name name, chose the name of service appropriate (according to the tnsnames.ora), tested the connected.
  
  This data source is provided as my DATA SOURCE for the connection pool.
  
  I picked the OIC 10 g / 11g as a calling interface...
  
  I make a mistake?

  You have two ways to connect to your database:
  * with ODBC
  * with OIC

  If you choose to in your ODBC connection pool, you must gave the name DSN (my_oracle_db), if you choose the BILL, give the TNSNAMES file.
