Error description

  • When an IBM MQ version 8 queue manager is upgraded to MQ version
    9, the migrated queue manager does not have SYSTEM.ADMIN.TOPIC
    object which was introduced in MQ version 9.
    

Local fix

  • Use the following runmqsc command to add the new object into the
    migrated
    queue manager:
      DEFINE TOPIC('SYSTEM.ADMIN.TOPIC') +
       TYPE(LOCAL) +
       TOPICSTR('$SYS/MQ') +
       DESCR('Root topic for MQ administrative topics') +
       CLUSTER(' ') +
       CLROUTE(DIRECT) +
       DURSUB(YES) +
       PUB(ENABLED) +
       SUB(ENABLED) +
       DEFPSIST(NO) +
       DEFPRTY(0) +
       DEFPRESP(SYNC) +
       PMSGDLV(ALLDUR) +
       NPMSGDLV(ALLAVAIL) +
       PUBSCOPE(QMGR) +
       SUBSCOPE(QMGR) +
       PROXYSUB(FIRSTUSE) +
       WILDCARD(BLOCK) +
       MDURMDL('SYSTEM.DURABLE.MODEL.QUEUE') +
       MNDURMDL('SYSTEM.NDURABLE.MODEL.QUEUE') +
       MCAST(DISABLED) +
       COMMINFO(' ') +
       USEDLQ(YES) +
       CUSTOM(' ') +
       REPLACE
    

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    All MQ users who migrate their MQ 8.0 queue managers to MQ 9.0
    
    
    Platforms affected:
    MultiPlatform
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    A logic error within the MQ queue manager migration code meant
    that the code created SYSTEM.ADMIN.TOPIC only when MQ 7.5 or
    lower level queue managers were migrated to MQ 9.0 level. The
    object was incorrectly not created when MQ 8.0 queue managers
    were migrated to MQ 9.0 level.
    

Problem conclusion

  • The code has been modified to create SYSTEM.ADMIN.TOPIC object
    when MQ 8.0 or lower level queue managers are migrated to MQ 9.0
    level.
