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).
    .

    ****************************************************************
    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.
