Error description

  • After IPL of the LPAR the CMAS and the MAS's are started.
    The TOR region tries to connect to the CPSM workload but
    this fails with the messages EYUWI0082E and EYUWM0401E.
    The CMAS trace shows the following exception trace entries:
    WMQB WMQM WMWC WLM EXCP  4 BUF2SML  CPSM CMASTC91 CMAS
    WMQM WMWC WMWC WLM EXCP 13 WMQMWMQB CPSM CMASTC91 CMAS
    WMWC XLOP WMWC WLM EXCP 16 WMWCWMQM CPSM CMASTC91 CMAS
    

Local fix

  • Use the COSH and COLM transactions to stop and restart the CPSM
    agend code or recycle the routing region.

    ****************************************************************
    * RECOMMENDATION: After applying the PTF that resolves this    *
    *                 APAR, all CMASes must be restarted.  Note    *
    *                 that the restarts do not need to occur at    *
    *                 the same time.                               *
    *                                                              *
    *                 Note that if any CMAS has exhibited the      *
    *                 symptoms of the problem, it will be          *
    *                 necessary to terminate not only that CMAS,   *
    *                 but all MASes and batch API programs that    *
    *                 connect to it, to ensure that the partial    *
    *                 workload has been removed from that CMAS.    *
    *                 The EYU9XENF utility can be used to check    *
    *                 which MASes and batch API programs are       *
    *                 connected to the CMAS.                       *
    *                                                              *
    *                 For details on the EYU9XENF utility refer to *
    *                 "CICS Transaction Server for z/OS Version 4  *
    *                 Release 2 CICSPlex SM Problem Determination" *
    *                 (GC34-7203-xx).                              *
    ****************************************************************
    When a CMAS imports a workload from another CMAS, the CMAS that
    exports the workload fills a queue with records that define the
    workload.  This queue is then returned to the importing CMAS,
    where method EYU0WMQB (WMQB) reads the records from the queue
    and calls various other methods to process them.
    
    If an affinity of lifetime PERMANENT, SYSTEM, PROCESS or
    ACTIVITY is active at the time of the export/import, then the
    exporting CMAS will add a WLMAFFET record for each of those
    affinities to the queue.  For CPSM V4R2M0, the size of the
    WLMATTEF record has increased from X'AC' to X'10F'.  However,
    WMQB was never updated to reflect this change.  Instead, it
    attempts to read the WLMAFFET record into a buffer that is too
    small.  This causes the import to fail at that point.
    

Problem conclusion

  • Copybook EYURWRKQ, which defines the workload records that are
    delivered in the export/import queue, has been updated to set a
    new equate with the maximum length of the queue records.  WMQB
    has been updated to use this new equate as the buffer length
    when requesting records from the queue.
