PQ98484; 4.0.7: Distributed transaction may complete inconsistently



APAR status
Closed as program error.

Error description
When running a distributed transaction across two servers with
interop mode active, the superior server failed. A request
from the superior to the subordinate server was inflight at
the time. When the superior was brought back up, it was
discovered that the transaction on the superior had
rolled-back, while the transaction on the subordinate had
committed.

When running a distributed transaction across two servers with

from the superior to the subordinate server was inflight at
the time. When the superior was brought back up, it was
discovered that the transaction on the superior had
rolled-back, while the transaction on the subordinate had
completed.
The problem occurred in JBrokerSupport where an exception
received from the superior server was correctly caught, but
the exception was then quietly ignored.
Problem conclusion
Class JBrokerSupport has been updated so that when the
exception is received, a TRANSACTION_ROLLEDBACK exception
will be thrown.
