Possible trouble of exception cause during error of 2PC

XMLWordPrintable

      I have test scenario where crash recovery of transaction is tested. I have two XA resources which process commit - meaning to 2PC. Sometimes during the commit connection to database is put down which causes the 2PC does not finish successfully.

      1. Enlist Test XA
      2. Enlist DB XA
      3. Prepare Test XA
      4. Prepare DB XA
      5. Commit Test XA
      6. Connection to DB is interrupted/closed
      7. Commit DB XA
      8. Exception is thrown and got by client

      There is issue in type of transaction that is returned back to client.

      For EAP6 it was (for JTA)
      java.rmi.RemoteException caused by javax.ejb.EJBException caused by javax.transaction.HeuristicMixedException

      If user does txn.commit() (or container did it on itself when CMT is used) and the problem described above occurs then user can got cause information that transaction failed as heuristic.

      For WFLY the situation changed. I can see that exception in the server.log is enhanced by suppressed exception and this one is returned as cause to client.

      The example of such exception stack trace is here

      The issue that I can see here (or at least it seems to me so) is that client does not have chance to find out what is the outcome of the commit operation. I mean the outcome is error but there is no details like if it was Heuristic outcome and what kind of it (http://docs.oracle.com/javaee/6/api/javax/transaction/UserTransaction.html#commit%28%29).
