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.

Problem summary
**************************************************************** * USERS AFFECTED: All. * **************************************************************** * PROBLEM DESCRIPTION: Incorrect issue of DFHPG0002 with an * * error code of x'0E09' or x'050D'. * **************************************************************** * RECOMMENDATION: * **************************************************************** 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'. Keywords: PGISREC PK05521 msgDFHPG0002 PG0002 0E09 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.
