IT31552: RDQM Preferred Location not being used correctly for stopped Queue Managers or when one node down

APAR status

Error description

• An RDQM Queue Manager's primary node did not match its Preferred
  Location when it should have done.
  

Local fix

Problem summary

• ****************************************************************
  USERS AFFECTED:
  Users of IBM MQ's RDQM's Preferred Locations feature.
  
  
  Platforms affected:
  Linux on x86-64
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  The Preferred Location feature of RDQM identifies the node where
  a Queue Manager should run if that node is available. When a
  Queue Manager was in a stopped/ended state, and its current
  primary node did not match its Preferred Location, it would not
  change to be on its Preferred Location. Also, if one node in the
  HA cluster was unavailable , editing a Queue Manager's Preferred
  Location would have no effect.
  

Problem conclusion

• The IBM MQ code has been corrected so that an RDQM Queue Manager
  will now make its primary node its Preferred Location, even if
  it is stopped, or if one node in the HA cluster is down.
