Error description

  • When IMS command delivery from AF using the IMSCMD REXX
    function is configured for DFSCMTI / ITASK processing only, if
    the IMS region is not available it will still attempt to use the
    BMP and because it's not configured will result in a U0428
    abend.  Repeated attempts will cause a backlog of matches
    that are queued on an internal ENQ.  The backlog can take a long
    time to clear and may result in a MAXRUN condition or may just
    delay delivery of commands to the IMS region once it becomes
    active.

    When IMS command delivery from AF using the IMSCMD REXX function
    is configured for DFSCMTI / ITASK processing only, if the IMS
    region is not available it will still attempt to use the BMP and
    because it's not configured will result in a U0428 abend.
    Repeated attempts will cause a backlog of matches that are
    queued on an internal ENQ.  The backlog can take a long time to
    clear and may result in a MAXRUN condition or may just delay
    delivery of commands to the IMS region once it becomes active.
    

Problem conclusion

  • If the DFSCMTI / ITASK is not available for the specific IMS
    region when using the IMSCMD REXX function, then use of the BMP
    as a backup method of command delivery should be made optional.
