Problem summary

  • ****************************************************************
    * USERS AFFECTED: All users of IBM MQ for z/OS Version 8       *
    *                 Release 0 Modification 0.                    *
    ****************************************************************
    * PROBLEM DESCRIPTION: System topics are defined with an       *
    *                      incorrect topic string ' ' when using   *
    *                      commands generated by the MAKEDEF       *
    *                      option of CSQUTIL.                      *
    *                      This can lead to topic strings          *
    *                      generated based on these objects being  *
    *                      unexpectedly prefixed with '/'.         *
    ****************************************************************
    When CSQUTIL is used with the MAKEDEF option, the utility
    creates the DEFINE TOPIC command assuming a minimum length of
    1 for the topic string attribute, resulting in topics with
    the null topic string '' replaced with a blank topic string ' '.
    However there are system topics (SYSTEM.BASE.TOPIC,
    SYSTEM.BROKER.DEFAULT.STREAM and SYSTEM.BROKER.DEFAULT.STREAM)
    which can validly contain a null topicstr.
    
    If this output is subsequently used to redefine the topics, this
    results in these system topics being defined with the wrong
    topic string.
    

Problem conclusion

  • CSQUCMDS is changed to correctly handle topics with a null
    topic string.
