Local fix
Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM MQ for z/OS Version 8 * * Release 0 Modification 0. * **************************************************************** * PROBLEM DESCRIPTION: The EXTRACT function of CSQ1LOGP can * * produce incorrect information when * * units of work contain failed MQPUT * * operations for large persistent * * messages. * **************************************************************** During the MQPUT of a message an error was detected after the IRHA pages for the message had been logged, but before the IRH8 or IRH9 had been logged, and the operation was correctly undone. However when CSQ1LEXT processes the log records, it does not correctly detect that the IRHA pages were part of a failed and undone operation, causing these pages to be attributed to the following message in the unit of work.
Problem conclusion
CSQ1LEXT is changed to correctly skip log records representing IRHA records for MQPUTs that failed.
