We are trying to run JBoss 6 with an Oracle XA datasource.

We started with jboss-6.0.0.Final\docs\examples\jca\oracle-xa-ds.xml for the datasource configuration.

We have been running into exceptions like the following:

The code does obtain connections both with and without transactions.

It started to appear that there is/was an issue with the <no-tx-separate-pools/> option in oracle-xa-ds.xml.

I looked up org.jboss.resource.connectionmanager.JBossManagedConnectionPool in the JMX Console and found NoTxSeparatePools = false.  So I tried other combinations like <no-tx-separate-pools>true</no-tx-separate-pools> and I cannot get NoTxSeparatePools = true.

I was able to change NoTxSeparatePools = true and apply the change in the JMX Console and then stop and start the MBean.  I then could run the code without any of the errors.

Does anyone know how I can configure  NoTxSeparatePools = true from my oracle-xa-ds.xml configuration or is this something that is a bug that a fix is needed for?

Thanks, Jeff
