Error description

  • After upgrading to WebSphere MQ v7, the broker migration fails
    using strmqbrk. The migration log shows:
    
    2010-09-02 13:24:12.947: ERROR: Couldn't create subscription
    (reason: 2515)
    2010-09-02 13:24:12.962: Migrating subscription:
    Topic:TEST/Blank/TEST, QMgr:TEST ,
    Queue:SYSTEM.TESTQ , Options:120001
    2010-09-02 13:24:12.962: New Options for Subscription: xxxxx
    (110010)
    
    The failure may also appear as:  WARNING: Unable to get
    SubIdentities due to reason: 2428
    
    Error logs show:
    Program(runmqbrk.exe) Host(TEST)
    AMQ5944: Migration has completed with errors. The Queued
    Publish/Subscribe Interface will need to be started manually
    
    EXPLANATION:
    The migration command has completed but not all data could be
    migrated. Details of the error(s) can be found in earlier error
    messages and the migration log.
    

Local fix

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    Users of WebSphere MQ v6 who make use of sub-identities and
    migrate their version 6 broker to WebSphere MQ using strmqbrk /
    runmqbrk
    
    Platforms affected:
    All Distributed (iSeries, all Unix and Windows)
    ****************************************************************
    PROBLEM SUMMARY:
    When the WebSphere MQ broker attempts to migrate a subscription,
    it receives a MQRC_GROUPING_NOT_ALTERABLE error. This is
    because it attempts to alter an existing subscription. To clear
    the way for migration in force mode, the previously existing
    subscription had to be removed and replaced by a new one.
    Removing the previously existing subscription was also impeded
    by existence of sub-identities.
    

Problem conclusion

  • This APAR changes the way in which an existing subscription
    with sub-identities is removed to make way for a new one.
    During migration, all the sub-identities are enumerated and
    each one of them is individually unsubscribed.
