Question:

When starting up Identity Manager on Jboss, these errors are producing in the logs:

"HQ154002: Could not create session: javax.resource.ResourceException: IJ000453: Unable to get managed connection for java:/JmsXA"

What causes this error and how can this be resolved to start up Identity Manager on my nodes?

Answer:

In a clustered environment, copying configuration data from one JBoss server to the other causes issues. There is an issue of duplicating the Universally Unique Identifier (UUID) in your HornetQ journal which is causing this error. (UUID is genereated when the journal is first created). Simply delete the HornetQ journal in the data directory from one of the nodes. This can be found in .../data/messagingjournal

After this is removed, restarted the node where the messagingjournal was removed and JBoss will create a new HornetQ journal with a unique UUID.
