After killing (-9) one node, the other node picks up and processes the messages. After that when I restart the fist node, I get the following on second pass of the recovery manager: "[com.arjuna.ats.internal.jta.resources.arjunacore.norecoveryxa] Could not find new XAResource to use for recovering non-serializable XAResource" I have done the configuration according to http://www.jboss.org/community/docs/DOC-13171, but that does not seem to fix it. Could someone point out the error in the configuration below: 1) conf/jbossjta-properties.xml : Node 1: Node 2: 2) deploy/hajndi-jms-ds.xml Node 1: RemoteProvider2 org.jboss.jms.jndi.JNDIProviderAdapter <!-- The combined connection factory --> XAConnectionFactory <!-- The queue connection factory --> XAConnectionFactory <!-- The topic factory --> XAConnectionFactory java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory java.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces java.naming.provider.url=node_2_hostname:1099 Node 2: RemoteProvider2 .... java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory java.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces java.naming.provider.url=node_1_hostname:1099 3) conf/oraclejta-properties.xml <transaction-service> </transaction-service> 4) Oracle user "jboss" has been granted following permissions: select on DBA_PENDING_TRANSACTIONS, execute on SYS.DBMS_SYSTEM View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4214919#...
