Problem summary
**************************************************************** * USERS AFFECTED: All users of WebSphere MQ Version 8 * * Release 0 Modification 0. * **************************************************************** * PROBLEM DESCRIPTION: After a backup pageset has been * * allocated and the queue manager is * * restarted 5C6-00C93C00 abends are * * generated in CSQIEXP2 or/and CSQISCP5 * * or/and other. The queue manager can * * terminate. * **************************************************************** * RECOMMENDATION: * **************************************************************** During queue manager restart after an old page set (backup) has been allocated, CSQIREXT should expand the page set to allocate the space required to restore all pages during forward log recovery. In this case, the page set expansion did not happen because the queue manager was previously restarted with the page set offline or suspended causing the loss of the high page number in the page set. Therefore CSQIREXT assumes that page set expansion is not required, causing media recovery of the page set to be performed incorrectly, resulting in various abends during subsequent processing.
Problem conclusion
The page set high page number is always saved in checkpoint records in the log even if the page set is offline or suspended.
