Local fix
Problem summary
**************************************************************** * USERS AFFECTED: All users of WebSphere MQ for z/OS Version 7 * * Release 1 Modification 0. * **************************************************************** * PROBLEM DESCRIPTION: Storage contraction of 64bit QuickPools * * may not contract all applicable pools * * when triggered manually. * **************************************************************** * RECOMMENDATION: * **************************************************************** When storage pool contraction is manually triggered it will attempt to 'contract' existing storage pools to attempt to reclaim any allocated but currently unused storage in order to relieve the storage constraint. When the 64bit QuickPools are being contracted, in certain circumstances an incorrect QuickPool identifier may be passed to the storage contraction routine and the intended storage pool may not be contracted.
Problem conclusion
Processing has been amended to ensure that the correct pool is contracted. 100Y CSQSP64T
