Error description

• Process cleanup service errors due to double scheduled cleanup
  .
  Business Flow Manager, process instance cleanup service runs
  twice for same cleanup job.
  .
  
  The following message can be seen twice in the systemOut.log
  within a very short time frame.
  .
  
  CWWBF0116I: The cleanup job <Clean up Job name> started.
  .
  Afterwards exceptions are possible due to a conflict between the
  2 identical clean up jobs e.g.
  .
  
  CWWBA0010E: Unexpected exception during execution.
  .
  CWWBF0111E: The cleanup service encountered an unexpected error
  when attempting to delete the
  _PI:9003013a.ca341738.73ea73f5.f38591c0 process instance
  .
  Reason for the failure: CWWBA0010E: Unexpected exception during
  execution.
  .
  DSRA0302E:  XAException occurred.  Error code is: XAER_NOTA(-4)
  Exception is: [jcc][t4][2041][12326][3.59.81] Error executing
  XAResource.rollback().  Server returned XAER_NOTA.
  ERRORCODE=-4203, SQLSTATE=null
  

Local fix

Problem summary

• Problem caused by user setting the cleanup schedule in the
  Admin console runtime tab (under servers/clusters > name >
  Business Flow Manager > Cleanup Service Settings).
  The product incorrectly allows this resulting in two schedules
  being set: one originating from the config tab and one
  originating from the runtime tab.
  
  This can result in two conflicting cleanup jobs running
  for what is effectively the same cleanup operation.
  The schedule originating in the runtime tab may be no longer
  visible via the runtime tab once the server has been restarted,
  however the schedule may still exist and trigger cleanup.
  

Problem conclusion

• The fix for this APAR will be included in product maintenance
  (Fix packs) and newer releases after this issue was discovered.
  It prevents the additional runtime definitions from being set by
  the user. If this issue has already occurred, the simple
  work around documented by this APAR can be used (see
  'circumvention').
  
  Preventative fix is targeted for the following fix packs
   WPS 7.0.0.6
   BPM 7.5.1.2
   BPM 8.0.1.2
  Preventative fix is targeted for BPM 8.5.0.0
