Symptoms


Before invoking xa_end(TMFAIL) through the resource adapter,
WebLogic invokes xa_end(TMSUSPEND), to suspend the transaction branch.
If a transaction branch is in a suspended state, when xa_end(TMFAIL) is
invoked on the Oracle XA interface, Oracle reports a protocol error.
This sequence should be valid, according to the XA specification,

The call to xa_end(TMSUSPEND) before calling xa_end(TMFAIL) was deliberately
added to WebLogic as part of patch (CR211194) and fixes a memory leak with
MQSeries.

Changes

Upgrade of Weblogic to versions where patch (CR211194) is implemented or
any other XA application calling xa_end(TMFAILl) after a xa_end(SUSPEND).
