    ****************************************************************
    During queue manager startup CSQMQMUP checks if the queue
    manager CCSID contains '$' '@' or '#' at a different codepoint
    to the majority of EBCDIC codepages, and if so, it calls MQ
    conversion services to locate a conversion table that can be
    used to convert these characters from CCSID 37 to the queue
    manager CCSID. If no such table can be located, the reported
    abend occurs and CSQMQMUP processing terminates, resulting in
    necessary processing to enable pubsub and signal that log
    archiving can continue being incorrectly skipped.
    

Problem conclusion

  • CSQMQMUP is changed to request conversion to different CCSIDS,
    depending on the queue manger CCSID to ensure that a valid table
    can be found. In the event that a suitable table still cannot be
    found, recovery processing has been added to allow CSQMQMUP
    processing to complete all necessary processing following the
    abend.
