Error description
Change Team finds there is a processing error in CSQMPRTP when called to remove a topic by cluster maintenance. If attempting to remove a clustered topic (once the object and grace period have expired) this can result in the krcE_NOT_FOUND reason code as there are no nodes that exist in the match space. This subsequently results in ABEND5C6-00D40085, causing the repository manager to stop. Additional search keywords : CSQX449I CSQX448E CSQM_ABEND_TOPICMGR_ERROR PRTP_ACTION_REMOVE CSQX053E CSQMLPLM

Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM MQ for z/OS Version 9 * * Release 0 Modification 0 and Release 1 * * Modification 0 * **************************************************************** * PROBLEM DESCRIPTION: When cluster maintenance runs, expired * * objects which are over their grace * * period are removed. * * If a clustered topic is removed during * * cluster maintenance, CSQMPRTP is called * * with action PRTP_ACTION_REMOVE (through * * QRPL_SPIPRTP). * * However, as cluster topics are pushed * * to all members in a cluster, if a * * repository in the cluster does not have * * anything in the match space (usually as * * SYSTEM.BASE.TOPIC has not been * * defined), CSQMPRTP will return krcE_NOT * * FOUND, which then results in CSQM_ABEND * * TOPICMGR_ERROR abend (5C6-00D40085). * * * * If CSQMPRTP returns krcE_NOT_FOUND an * * abend should not be thrown. * **************************************************************** When the customer deleted a cluster topic, because one of the repositories in the cluster did not have anything in the match space (usually as SYSTEM.BASE.TOPIC has not been defined), there was a CSQM_ABEND_TOPICMGR_ERROR abend (5C6-00D40085)
Problem conclusion
Code in csqmprtp.plx corrected so that if CSQMPRTP returns krcE_NOT_FOUND an abend is not thrown.
