Error description
An application running against a queue manager at WMQ V7.1 + UK80091 (PM58798) receives an ABEND0C4 in CSQ7COLL at offet 29E4, when an MQPUT is done specifying a non-zero handle and if no previous MQOPEN had been performed. The abend occurs because some WebSphere MQ blocks are not initialized as a result of the missing MQOPEN.
Local fix
a bypass could be to disable MQ statistics .
Problem summary
**************************************************************** * USERS AFFECTED: All users of WebSphere MQ for z/OS Version 7 * * Release 0 Modification 1 and All users of * * WebSphere MQ for z/OS Version 7 Release 1 * * Modification 0. * **************************************************************** * PROBLEM DESCRIPTION: After applying PTF UK80090(V701) * * or UK80091(V710) on a queue manager * * where class 3 accounting trace is * * enabled an MQ API call will fail with * * an S0C4 in CSQ7COLL if a previous * * MQOPEN was not performed. The API call * * will return MQRC_UNEXPECTED_ERROR * * (RC 2195). * **************************************************************** * RECOMMENDATION: * **************************************************************** The S0C4 in the queue manager, and the unexpected return code MQRC_UNEXPECTED_ERROR (RC 2195) is caused by the changes made by the PTF. The PTF change validates the object handle provided to the MQ API call by checking the MHPV. The MHPV does not exist if no MQOPEN calls have been made by the application. As the MHPV is referenced by the checks, if the MHPV has not been created, a S0C4 abend may be caused within the queue manager.
Problem conclusion
The allocation of the WQSTAT object now checks to ensure the MHPV has been created previously before attempting to reference it. 010Y 100Y CSQ7COLL
