| Error description
When completing a distributed transaction on two servers, the
coordinating server asks the subordinate server to prepare to
commit. If the subordinate server elects to rollback and rolls
back, this decision is not passed back to the coordinating
server, which commits its portion of the transaction,
resulting in inconsistent data. No error messages or exceptions
are generated. If the subordinate server elects to commit,
the coordinating server also commits as expected. This problem
has only been observed when WebSphere is configured to run in
Interoperability mode. Local fixProblem summary
****************************************************************
* USERS AFFECTED: Application servers using WebSphere's *

* PROBLEM DESCRIPTION: During commit processing a down stream *
* server can elect ro rollback the Tx *
* but this decision is not given to the *
* co-ordinating server who may commit *

****************************************************************
* RECOMMENDATION: *
****************************************************************
Possible Data Inconsistencies when running in Interoperability
mode. Problem conclusion
Problem fixed by defining a TxListener interface. Coordinating
server is now notified of down stream servers decisions. Temporary fixComments
