**************************************************************** * USERS AFFECTED: * * All DB2 12 for z/OS users of the LOAD utility with ENFORCE * * CONSTRAINTS. * **************************************************************** * PROBLEM DESCRIPTION: * * ABEND04E RC00E4001C with DSNT375I and DSNT500I, RC00C90088, * * TYPE 304 during concurrent LOAD INTO TABLE PART x REPLACE * * utility jobs of different partitions of the same dependent * * table. * **************************************************************** * RECOMMENDATION: * * Apply corrective PTF when available * **************************************************************** User ran concurrent LOAD INTO TABLE PART x REPLACE utility jobs of different partitions of the same dependent table space with ENFORCE CONSTRAINTS. Several of the LOAD utility jobs abended with an ABEND04E RC00E4001C due to RC00C90088 DEADLOCK issuing MSGDSNT375I and MSGDSNT500I naming SYSTSTSP as the RESOURCE UNAVAILABLE. Deadlock scenario: Loser LOAD INTO TABLE PART x REPLACE utility in the UTILINIT phase acquiring object information: Held a shared lock on SYSTABLES Waiting on a shared lock for SYSTABLESPACE Winner LOAD INTO TABLE PART x REPLACE utility in the ENFORCE phase against a different partition of the same dependent table: Held an exclusive lock on SYSTABLESPACE Waiting on an exclusive lock for SYSTABLES The problem can also occur with other utilities running concurrently with a LOAD ENFORCE CONSTRAINTS INTO TABLE PART x REPLACE utility. A commit is needed for LOAD after catalog access when turning off CHECK PENDING status in the catalog.
