Error description

  • The DFHPG0002 x'0E09' occurred when DFHPGAI 's recovery routine
    received control following an error (in this case an abend0C4),
    and issued an UNLOCK request for the shared PGLOCK. Trace shows
    that this UNLOCK request fails due to reason SHARED_LOCK_FREE:
    .
    00076 L800F PG 0E09 PGAI *EXC* Recovery_release_pglock_error
                                      reason(SHARED_LOCK_FREE)
    .
    DFHPGAI tests for lock manager exception, LMLM_NOT_LOCK_OWNER ,
    but should also test for LMLM_SHARED_LOCK_FREE , or perhaps
    should not include the :refstep.recovery_release_shared_pglock
    fragment at all.

    ****************************************************************
    An abend 0C4 in DFHPGAI occurred and this caused DFHPGAI's
    recovery routine PGAIREC to receive control.  PGAIREC issued
    a DFHLMLM UNLOCK for a SHARED PG_LOCK.  However, the task
    did not own a SHARED PG_LOCK and the UNLOCK request returned
    an EXCEPTION response with a reason of SHARED_LOCK_FREE.
    This was a valid response from the UNLOCK.  However, when
    control returned to PGAIREC, it treated this response as
    an error condition and issued DFHPG0002 with an error code
    of x'0E09'. A similar condition can occur when the recovery
    routine for DFHPGIS is driven, DFHPG0002 may be issued with an
    error code of x'050D'.

Problem conclusion

  • PGAIREC and PGISREC in DFHPGAI and DFHPGIS respectively have
    been modified to cater for an exception with reason
    SHARED_LOCK_FREE on the UNLOCK call as a valid response.
