Error description
The problem in this case is when an attribute is altered which is not an attribute which results in a kiss-and-tell being sent. In this scenario, other QMGRs are expected to refresh their copy of the queue MQSH when processing a DISPLAY QUEUE command. APAR PH52830 changed this processing to use the in-memory MQSH if there is one which results in the problem.
Local fix
Removing the fix of PH52830
Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM MQ for z/OS Version 9 * * Release 2 Modification 0 and * * Release 3 Modification 0, * **************************************************************** * PROBLEM DESCRIPTION: Following application of APAR PH52830, * * changes to shared queue attributes * * are not shown on other queue managers * * if the queue has never been opened * * successfully, or is not currently * * open/connected. * * Where the queue is not currently open * * any subsequent DISPLAY QUEUE command * * will return the correctly updated * * attribute values. * **************************************************************** When processing DISPLAY QUEUE, the changes in PH52830 cause the currently cached object definition to be used, avoiding unnecessary DB2 lookups. In cases where the queue has never been opened, or the queue is not currently open/connected in the CF recent changes to the queue definition are not always reflected in the cached object, leading to out of date values being displayed.
Problem conclusion
CSQM1DQU has been changed to refresh the cached view of the object after filtering has determined that the object should be displayed, so that any recent changes to the object are correctly displayed.
