    datasource pool is alocated twice

    erahamim Newbie

      Hi,
      I'm using jboss 4.0.5. I have XA datasource with oracle 10 as database. I init my application using a start up servlet. In the init method of the servlet I do some queries to database which are done ok. Then in the first time that I try to get a database connection using stateless ejb I see that the jboss is allocate the pool again.

      So even that my data source is defined in oracle-xa-ds.xml
      <min-pool-size>10</min-pool-size>
      <max-pool-size>40</max-pool-size>

      I can see in the JCA jmx JBossManagedConnectionPool that
      AvailableConnectionCount - 80
      ConnectionCount - 20
      MinSize - 10
      MaxSize - 40

      Before getting the connection from ejb
      AvailableConnectionCount 40
      ConnectionCount is 10.
      MinSize - 10
      MaxSize - 40


      I always get the connection in the same way
      (DataSource) ic.lookup("java:/DataSourceDS").getConnection();
      The different is the context that I come from, servlet or ejb.

      Any idea?

      My full data source definition is:

      <xa-datasource>
      <jndi-name>DataSourceDS</jndi-name>
      <track-connection-by-tx/>
      <isSameRM-override-value>false</isSameRM-override-value>
      <xa-datasource-class>oracle.jdbc.xa.client.OracleXADataSource</xa-datasource-class>
      <xa-datasource-property name="URL">jdbc:oracle:thin:@(DESCRIPTION= (ADDRESS_LIST=(LOAD_BALANCE=on) (ADDRESS=(PROTOCOL=TCP)(HOST=1.2.3.4)(PORT=1521)) (ADDRESS=(PROTOCOL=TCP)(HOST=1.2.3.5)(PORT=1521)))(CONNECT_DATA=(SERVICE_NAME=name)))</xa-datasource-property>
      <xa-datasource-property name="User">user</xa-datasource-property>
      <xa-datasource-property name="Password">password</xa-datasource-property>
      <exception-sorter-class-name>org.jboss.resource.adapter.jdbc.vendor.OracleExceptionSorter</exception-sorter-class-name>
      <no-tx-separate-pools/>
      <blocking-timeout-millis>1111</blocking-timeout-millis>
      <min-pool-size>10</min-pool-size>
      <max-pool-size>40</max-pool-size>
      <idle-timeout-minutes>5</idle-timeout-minutes>
      <track-statements>true</track-statements>
      <prepared-statement-cache-size>100</prepared-statement-cache-size>

      <type-mapping>Oracle9i</type-mapping>

      </xa-datasource>
