Problem summary
**************************************************************** * USERS AFFECTED: All users of WebSphere MQ for z/OS Version 7 * * Release 0 Modification 1 and Version 7 * * Release 1 Modification 0. * **************************************************************** * PROBLEM DESCRIPTION: ABN=5C6-00D40085 and the qmgr * * terminates with REASON=00940001. * **************************************************************** * RECOMMENDATION: * **************************************************************** During end-thread processing for a client channel, a return code of KRCE_IDENTITY_MISMATCH is returned by the routine kqiTopicDeregisterSubscriber in CMQXKTPT. CSQMCLS2 does not have any code to handle this return code so issues abend 5C6 00D40085 (CSQM_ABEND_TOPICMGR_ERROR) which results in the qmgr terminating with reason code 00940001. The return code is generated because the pubsub topic manager has been shut down (using ALT QMGR PSMODE(DISABLED)), and restarted at some point leaving handles pointing to freed subscription storage. This storage is reused causing a mismatch between what is expected and what is actually in the storage.
Problem conclusion
The module CSQTOCTH has been added to clear handles referencing topic manager storage when topic manager is shutdown. CSQMCLS2 has been altered to handle KRCE_IDENTITY_MISMATCH correctly. 010Y 100Y CMQXKTPT CMQXKTPU CSQMCLS2 CSQTOCTH CSQTOEPL HMS7010J HMS7100J
