Issue

We are running into row lock contention across nodes in their Oracle RAC cluster. Can we configure JBoss datasources and transaction manager to support RAC affinity (meaning that the application guarantees that all branches of one XA transaction will always land on one RAC node) or if the application server can be configured to use multiple Oracle DTP services for load balancing?

Environment
