PI51003: WMQ CLUSTER TOPIC NOT PROPAGATED FROM WMQ FULL REPOSITORY IN Z/OS TO PARTIAL REPOSITORIES

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• When it is created a Topic in a Cluster, the info is only
  propagated to the Full Repositories in the Cluster, but not to
  the Partial Repositories. The two Full Repositories are located
  in a WMQ in z/OS, and the Partial Repositories are located also
  in WMQ in z/OS and WMQ in Distributed Platforms.
  
  The dump shows that QMGR does not have a hash (#) subscription,
  and that is the problem. A REFRESH CLUSTER on that partial
  should have caused the # subscription to be sent to QMGR but it
  is still not there. It has either not been sent, or QMGR is
  rejecting it.

  * PROBLEM DESCRIPTION: Clustered topics are not correctly      *
  *                      propagated to partial repository queue  *

  * RECOMMENDATION:                                              *
  ****************************************************************
  When topics are defined in a cluster, a special subscription
  (SUBSCRIPTION_FOR_ALL_CLTS) is created and used to cause the
  topic definitions to be distributed to all queue managers in the
  cluster. This subscription includes characters that are variant
  in EBCDIC, and it is possible that when the command message sent
  to create the subscription is converted in to a given queue
  manager's ccsid, these special characters are at a different
  code point to that expected. When this occurs, the subscription
  is not processed correctly and any cluster topic
  definitions/updates will not be correctly propagated around the
  cluster.
  

Problem conclusion

• The code responsible for handing the SUBSCRIPTION_FOR_ALL_CLTS
  subscription is updated to account for the inclusion of variant
  characters, so that any future definitions and/or updates to
  clustered topics are correctly propagated around the cluster.
