Error description
An ABEND5C6 occurred with this dump title: CSQ1,ABN=5C6-00940029,U=SYSOPR ,C=R3600.710.CMC -CSQMCIG2, M=CSQGFRCV,LOC=CSQMCLLM.CSQMCIG2+00000EAA Reason code 00940029 means "Bad URE log rec". The queue manager (CSQ1 in this example) receives a request to resolve an indoubt group UR, and tries to communicate with other queue managers in the Queue Sharing Group ( QSG ) to resolve it. As the other queue manager in question is not available (queue manager id 03), CSQ1 goes ahead and reads the logs for that queue manager. It finds an IMS Bridge checkpoint log record, containing TTE entries, which does not have the expected URE layout. This is unexpected and causes the abend to be issued. Additional Symptom(s) Search Keyword(s): ABEND5C6 ABENDS5C6 5C6 S5C6 S05C6 00940029 . ABN=5C6-0094002A,U=SYSOPR ,C=R3600.710.CMC -CSQMCIG2, M=CSQGFRCV,LOC=CSQMCLLM.CSQMCIG2+00000EC8 where 0094002A means "Bad RURE log rec".

Problem summary
**************************************************************** * USERS AFFECTED: All users of WebSphere MQ for z/OS Version 7 * * Release 1 Modification 0. * **************************************************************** * PROBLEM DESCRIPTION: When inquiring indoubt group units of * * recovery the queue manager abends with * * 5C6-00940029 or 5C6-0094002A. * * This only happens in a QSG environment * * where some of the queue managers have * * IMS bridge queues defined. * **************************************************************** * RECOMMENDATION: * **************************************************************** The IMS Bridge writes log records during checkpoints that look similar to URE and RURE log records. Under certain conditions, the code inquiring group indoubt units of work (CSQMCIG2) processes the IMS Bridge records, even though they should be ignored. CSQMCIG2 detects the missing eye catcher, and the abend is issued.
Problem conclusion
The code has been changed to correctly ignore IMS Bridge log records and complete the inquire group ur request. 100Y CSQMCIG2
