I am running JBoss 5.10 on RHEL5  in a cluster and have an Oracle 11i RAC database. I have searched and not seen this issue in any discussions. I have successfully set up oracle-ds.xml and it is connecting properly.  My question is that I want to replace Hypersonic with a different Oracle DB that has been created for this purpose.  In my oracle-ds.xml, I have created a second datasource to replace the Hypersonic with Oracle.  So I have: <datasources>    <local-tx-datasource>      <jndi-name>jdbc/datasource1</jndi-name>         <!--  This is the big Oracle DB  -->      .... { first Oracle user/pw }    </local-tx-datasource>    <local-tx-datasource>      <jndi-name>DefaultDS</jndi-name>                <!--  This is the minimal Oracle DB to replace Hypersonic  -->     .....  { second Oracle user/pw  }    </local-tx-datasource> </datasources> I have removed hsqldb-ds.xml and added /messaging/oracle-persistence-service.xml. I do not see any errors in the logs.  Is this the correct approach?  Anything I missed?  Should I see entries in this new Oracle table I have to replace Hypersonic?  How do I know it is working.
