Error description
A CPU SYSPLEX parallel query with 16 degrees, where 8 of them are running in the parent's local DB2 system requires workfile resources, but have a soft cancel is received involving an ABEND04E RC00E50013 in DSNTTRUN, then during cleanup since we're in the ABORT path, an ABEND 04E RC00C90101 is seen in DSNILRBK with ERQUAL 5009, since we're trying to free the associated workfile PSFIREC block for a workfile with obid x'03EB', but the PSFIREC does not exist.

Problem summary
**************************************************************** * USERS AFFECTED: All DB2 10 & 11 users for z/OS with CPU- * * SYSPLEX Parallel Query. * **************************************************************** * PROBLEM DESCRIPTION: ABEND04E with RC00C90101 in DSNILRBK * * ERQUAL5009 * **************************************************************** * RECOMMENDATION: * **************************************************************** For CPU-SYSPLEX Parallel query, if it's running in a Data Sharing Environment, the parent task will use each workfile coming from remote child task to generate a remote cross-CPC workfile. Under this sysplex condition, the remote cross-CPC workfile will have a 'fake' Object Descriptor (OBDREC) instead of the actual one. So deleting the internal control block PSFIREC of this remote workfile will cause the reported abend.
Problem conclusion
DB2 is changed to avoid deleting the PSFIREC of this type of workfile.
