****************************************************************
If an application using DB2 RRSAF is canceled, a DB2 UR may
remain in-doubt after DB2 deferred EOT processing has finished.
The application may have already terminated and z/OS RRS has
ended the z/OS RRS UR.  The in-doubt DB2 UR may remain until it
is manually resolved or DB2 is stopped and restarted.

    



Problem conclusion


    

  • DB2 module DSN3TM00 has been updated to ensure that a DB2
in-doubt UR that was processed for an RRS implicit backout will
be automatically aborted.
