Error description

  • An attempt to delete a durable subscription fails with AMQ8147:
    WebSphere MQ object <managed_queue> not found.
    
    The following is seen in runmqsc when running a DELETE SUB
    command:
    DELETE SUB
    SUBID(<subscription_id>)
    3 : DELETE SUB
    SUBID(<subscription_id>)
    AMQ8147: WebSphere MQ object <managed_queue> not found.
    

Local fix

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    All users attempting to delete a durable subscription
    
    Platforms affected:
    All Distributed (iSeries, all Unix and Windows)
    ****************************************************************
    PROBLEM SUMMARY:
    The function which unsubscribes subscribers from a subscription
    when it is deleted, performs some actions against the managed
    queue which backs the subscription. In the event this managed
    queue has been deleted, the delete subscription attempt would
    fail with AMQ8147 stating that the object could not be found.
    

Problem conclusion

  • The code which deletes the durable subscription has been altered
    to handle the case in which the managed queue for that
    subscription has already been deleted, thereby allowing the
    deletion of the subscription to succeed.
