PM64842: FFST FOR MISSING SUBSCRIPTION INCORRECTLY ISSUED 12/05/17 PTF PECHANGE

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• FFST for missing subscription incorrectly issued
  .
  Additional information:
  After the fix for this APAR has been applied, MQ will no longer
  remake the subscription since it is impossible to know which
  type is required (QMName or UUID). Because these subscriptions
  are not remade they remain 'missing' and FFST dumps are taken
  hourly (instead of just once) to indicate an error.
  .
  The best way to fix the missing subscription is to a REFRESH
  CLUSTER on the queue manager getting the CSQX053E error. This
  will delete the CLQMGR objects, which will then be remade whan
  an application requests them. Subscriptions will also be made at
  the same time.

  * PROBLEM DESCRIPTION: CSQX053E message indicating a CSQSNAP   *
  *                      dump (FFST) has been issued. The FFST   *
  *                      shows that a "Missing subscription"     *
  *                      detected by rrmMaintainClqMgr.          *

  * RECOMMENDATION:                                              *
  ****************************************************************
  The hourly cluster maintenance cycle checks every CLQMGR to see
  if its refresh bit is on, and if so it checks to see that there
  are subscriptions for the CLQMGR. However there are two types
  of CLQMGR subscriptions, either flagged as
  rfxSubsFlags_CLUSTER_Q_MGR_NAME or
  rfxSubsFlags_CLUSTER_Q_MGR_UUID. However, the rrmMaintainCLQMGR
  code was only checking for the latter type, and if none were
  found then an FFST was issued.
  

Problem conclusion

• rrmMaintainCLQMGR now checks for both types of CLQMGR
  subscription, and will only issue an FFST if none are found.
