****************************************************************
The WebSphere Application Server WS-AT implementation on zOS
forgets participants that do not vote on prepare within the
timeout period.  Such participants may be indoubt but the
prepared response has been lost.  In such a case, the
participant will eventually ask for replay, so the transaction
will be resolved, but not  in as timely a fashion as may be
expected. Additionallly, if a WebSphere Application Server is a
participant in a WS-AT distributed transaction on zOS, it votes
aborted in response to a commit message when it does not
recognise the transaction.  The correct behaviour is to vote
committed.
Problem conclusion
The behaviour has been changed so that the coordinator does
not forget participants that time-out on prepare.  A rollback
message is sent as part of the mainline transaction completion,
rather than waiting for the replay request.  This avoids an
in-doubt participant holding locks on resources for longer than
necessary in this case. If a WebSphere Application Server is a
participant in a WS-AT distributed transaction on z/OS, it now
votes committed in response to a commit message when it does not
recognise the transaction.
