Error description

• An Error message:
  CSQU638E CSQUMGMB Unable to make subscription
   reason=2085
   subscription name ssid NTOMS.SWIFTNET.DNI_N_EVENT
   C1D4D8E70000000000
   topic +/MSAOU/+/+/+/+
  .
  An error message "CSQU638E CSQUMGMB Unable to make
  subscription reason=2085" occurs when using the
  CSQUMGMB utility to migrate the publish/subscribe
  configuration data for WebSphere Business Integration
  for Financial Networks (WBIFN).
  .
  It looks like the failure is due to an attempt
  to subscribe using a topic object name 'EventId'
  for topic string 'EventId' even though there is
  an existing topic object associated with this
  topic string for this subscription point
  (namely,NTOMS.SWIFTNET.DNI.EVENTID).
  .
  

Local fix

• Deregister the topic and then register the
  event subscription after the CSQUMGMB Migration
  utility job completed successfully.

  ****************************************************************
  The Pub/Sub migration utility CSQUMGMB is used to migrate a
  Pub/Sub topology from a WebSphere Event Broker Version 6.0 or
  WebSphere Message Broker Version 6.0 or 6.1 to WebSphere MQ
  Version 7.0.1 and later versions.
  
  When the tool processes a subscription point, the name of the
  subscription point is used for the corresponding name of the
  topic object to be created, and the topic string itself.
  However, if a topic object with this topic string already
  exists, the existing topic object is added to
  SYSTEM.QPUBSUB.SUBPOINT.NAMELIST only.
  
  When a subscription corresponding to this topic string is then
  created, the subscription descriptor has not been updated to
  reflect the existing topic object name found earlier and
  attempts to create the subscription for an object name matching
  the subscription point name. Since the topic object is not
  found, the create fails with MQRC 2085.
  
  The following message is observed in the migration log.
  
  Warning: Unable to create a subscription to topic, reason code:
  2085.
  
  Migration then continues, without creating the corresponding
  subscriptions for this subscription point.
  

Problem conclusion

• The code has been changed to reflect an existing topic object
  name, if found, in the subscription descriptor before creating
  a subscription for this subscription point.
