Error when preparing a transaction for commit

[Naveen Sampra]

Hi All,

I am reading a JMS message using MDB; based on message values, using CMP 1.1 to read from DataSource1(DB2 - os/390 database) and using CMP 2.0 to update DataSource2(DB2 - Linux UDB database).

I'm using the V5.0 Test server on WSAD 5.1.1 for testing. The same problem occurs in V5.1 Test server.

When returning from the onMessage() method, the following error is thrown. The MDB calls a stateless session bean to do the processing. I am using 2PC database drivers. The JMS provider(WebSphere MQ) is registered for 2PC.

Any suggestions as to what I can try to get rid of the error.

XAER_RMFAIL means "unavailable resource manager", it looks like your global transaction is timing out. Try to increase timeout value
