Error description
The automatically defined channel CLUSSDR transmission queues are not correctly removed when removing a QMGR from a cluster. If by additionally deleting the automatically defined channel CLUSSDR transmission queues, CSQX036E is issued as below when the CHINIT is restarted: CSQX036E +CSQ1 CSQXREPO Unable to open QUEUE(SYSTEM.CLUSTER.TRANSMIT.CLUS1.CHL1), MQCC=2 MQRC=2085 (MQRC_UNKNOWN_OBJECT_NAME) However many "CLUSSDR XMITQ Record" records are in the SYSTEM.CHANNEL.SYNCQ queue for CLUSSDR transmission queues which no longer exist. Message CSQX036E is only issued once for the first queue which failed an open in response to the rrcE_MQOPEN_FAILED once cluster reconciliation is complete.

Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM MQ for z/OS Version 9 * * Release 2 Modification 0, * * Release 3 Modification 0, and * * Release 4 Modification 0. * **************************************************************** * PROBLEM DESCRIPTION: During Cluster Reconciliation, the * * message CSQX036E would only be issued * * once if a queue could not be opened, * * even if multiple queues failed. * **************************************************************** The code which handles cluster reconciliation only reports errors at the end of the process, resulting in only one error being reported, even if there were multiple.
Problem conclusion
The code has been changed to report errors immediately after each failed attempt to open a queue, so that CSQX036E is issued for each failing object.
