Error description

  • When trying to load a workload specification the following
    messages occur:
    .
    EYUWM0400I Workload Specification  (WLSPC) has been successfully
     installed for context (PLEX) -  initiated by CMAS (CMASA)
    EYUWM0401E Workload Specification (WLSPC) failed to install for

    EYUWI0081I WLM Workload build process for context (PLEX) has
     been completed - initiated by CMAS (CMASA)

    EYUWM0401E Workload Specification (WLSPC) failed to install for
     context (PLEX)  - initiated by join of router (region3)
    .
    The query workload request if failing because SCLA is returning
    a status of XCLA_DUPLICATE_KEY on the ADDCLST function.  From
    the EYUWI0082E message, CMASA believes CMASB has the workload.

    * 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.                               *
    ****************************************************************
    When a workload does not exist under a CMAS, its creation is
    initiated when the first routing region for the workload starts.
    Method EYU0WMWC (WMWC) starts under transaction WMWC to perform
    the build.  If another routing region for the workload starts at
    the same time, a second instance of WMWC will be created.  In
    most situations, the second instance of WMWC will wait for the
    first to complete, at which time it will recognize that the
    workload has been built, and will not attempt to build the
    workload also.  However, in some situations, both WMWC processes
    can execute simultaneously, resulting in the errors documented
    above.
    

Problem conclusion

  • WMWC has been updated to issue a CICS ENQ upon starting.  The
    resource name of the enqueue will be a concatenation of the
    CICSplex name and the workload name (WLMSPEC) that the routing
    region is associated with.  After completing the workload build,
    WMWC will release the enqueue.  This will ensure that the
    workload build process is serialized.

Comments

  • A CMAS may fail to install a CPSM WLM
    workload properly when two or more
    routing regions start at the same time
    and attempt to import the workload.
