Error description
During a QUIESCE utility with more than 50,000 objects, IRLM abended with ABENDU2022 MODULE DXRRL010 OFFSET0FFA. This abend was due to XES ABEND071 RC00000030 There was a false 'spin' detected due to a high volume of DB2 Utility locks with zeros for hash value.
Local fix
reduce number of objects for a single utility
Problem summary
**************************************************************** * USERS AFFECTED: All DB2 10 for z/OS users of utilities. * **************************************************************** * PROBLEM DESCRIPTION: ABENDU2022 at DXRRL010 OFFSET0FFA and * * ABENDS0071 RC00000030 at IXLR1GLC * * during a QUIESCE utility running on a * * large object list defined by a LISTDEF, * * resulting in ABEND04E RC00E40020. * **************************************************************** * RECOMMENDATION: Apply corrective PTF when available. * **************************************************************** A QUIESCE ran on a large object list defined by a LISTDEF which contained more than 10000 table spaces. ABENDU2022 at DXRRL010 + x'0FFA' and ABEND0071 RC00000030 at IXLR1GLC occurred during the serialization processing of the QUIESCE utility, resulting in ABEND04E RC00E40020. This problem occurred because a lock used for utility serialization was requested without a hash value, causing IRLM to scan a large resource list and cause the abends. This problem could also occur for any DB2 z/OS utility operating on a large list of objects. Additional Symptom: ABENDS0071 RC00000038/RC00000010 ABEND026 RC0C3E0101
Problem conclusion
PM83559 is a pre-conditioning APAR that includes changes to support the fix for the reported problem, which will be enabled via another APAR at a later date. Changes in PM83559 should be generally transparent to users. In a data sharing group, the fix for this pre-conditioning APAR must be applied to all members before the later enabling APAR, when available, is applied to any member. The fix for the reported problem will not be effective until it is enabled by the follow-on APAR. Collectively, the APARs change utilities code to obtain the lock(s) used to serialize utilities with an appropriate hash value.
Temporary fix
