Error description
The customer is running WebSphere MQ V7.1 and they have an MQ batch job doing pub/sub that received an abend0C4 in the MQ MSTR adress space. The batch job encountered an MQRC 2195 MQRC_UNEXPECTED_ERROR. . 2014-03-21 19:38:35.692638 batchjob ERROR ON MQPUT, MQOD- OBJECTNAME: MY.MQ.OBJECT COMP-CODE: 2 REASON: 2195 QMGRNAME: CSQ1 . STC16293 IEA794I SVC DUMP HAS CAPTURED: 390 DUMPID=005 REQUESTED BY JOB (batchjob) DUMP TITLE=CSQ1,ABN=0C4-00000011,U=userid , C=R3600.710.UNKNOWN ,M=CSQGFRCV,LOC=CSQMLPLM.CSQMTPUT+00000XXX . The Change Team has determined the cause of the problem. The ABEND0C4 occurs when testing the storage pointed by CR15. This abend is not unexpected and recovery routine CSQGFRCV has code to retry from this, and no dump should be taken and processing should continue. However, there is a problem with the retry code when the 0C4 occurs when first setting up the FRE, as FRESPREP will be zero, which leads to the 0C4 dump being taken.
Local fix
Problem summary
**************************************************************** * USERS AFFECTED: All users of WebSphere MQ Version 7 * * Release 1 Modification 0. * **************************************************************** * PROBLEM DESCRIPTION: MQPUT returns MQRC 2195 * * (MQRC_UNEXPECTED_ERROR) and generates * * 0C4 abend in CSQMTPUT when publishing * * messages to topics. * **************************************************************** * RECOMMENDATION: * **************************************************************** CSQMTPUT generates a 0C4 abend when establishing the recovery environment to intercept exceptions and abends. The recovery routine CSQGFRCV does not take the correct action to retry the process in CSQMTPUT avoiding generating the dump.
Problem conclusion
CSQGFRCV recovery routine used by CSQMTPUT has been changed to take the correct retry action resuming the process in CSQMTPUT, and avoiding the generation of the 0C4 dump. 100Y CSQGFRCV CSQMTPUT
