JTA with WLS 8.1 sp5 and Oracle 10.1.0.4

Question

Hi,
          I am testing a global transaction involving two EJBs (stateless session beans) running on two separate WebLogic servers. Each ejb calls an Oracle stored procedure against a different datbase. One ejb is deployed on one server the other one on the second server.
          I want to know if it is mandatory to set up a trust relationship between the two servers. The reason I ask is that it seems the transaction is working without it (with the SecurityIdentity automatically downgraded to 'anonymous').
          However it only seems to consistently work between certain servers and randomly failing when using a different pair of servers.
          Thanks
          Cristian

          Ok, you should make sure you're using consistent SecurityInteropMode settings
          on the different servers. Trust is only needed if the servers are on different
          domains otherwise trust is not needed. We made many changes to correct a downgrade
          issue on different subsystems JTA, JMS, EJB in 81sp6. There is a patch
          available for 81sp5 for this.
          Please read: http://e-docs.bea.com/wls/docs81/ConsoleHelp/jta.html#1120356
