Error description

  • When a QUIESCE command is issued, the MAS is set as
    QUIESCING allowing just the routing of work associated with the
    active affinities.  When it is determined that there are no
    affinities, message EYUWM0423I is issued and the MAS is marked
    as QUIESCED.
    Now, to alert any automation tool that a particular MAS is
    quiescing, a message is required to indicate asap that a QUIESCE
    command has been issued against a particular MAS.
    This will not change the behaviour of actual message EYUWM0423I

    * USERS AFFECTED: All CICSPlex SM V4R2M0 Users                 *
    ****************************************************************
    * PROBLEM DESCRIPTION: When a quiesce action is issued for a   *
    *                      CPSM WLM target region, the region may  *
    *                      no longer be available for routing at   *
    *                      that time, but message EYUWM0423I is    *
    *                      not issued for at least 60 seconds past *
    *                      that time.  It is desirable for a       *
    *                      message to be issued when the quiesce   *
    *                      is issued.                              *
    ****************************************************************
    * 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 quiesce action is issued for a CPSM WLM target region,
    method EYU0WAUO (WAUO) runs in all CMASes which have joined the
    target region to a workload.  WAUO marks the status of the
    target region as quiescing, which stops all new transactions
    from being routed to the target region, and then starts method
    EYU0WMQS to run under a separate task, to determine if any
    affinties exist for the target region.  Since the affinities may
    be local to other CMASes, WMQS starts a timer for 60 seconds and
    waits for the timer to expire.  Once it does, if there are
    affinities existing, WMQS resets the timer and waits.  When WMQS
    awakes from a timer wait and finds that all affinites have been
    deleted, the target region's status is set to quiesced, EYULOG
    message EYUWM0423I is issued to document that the target region
    is quiesced, and the WMQS task terminates.
    
    Once WAUO marks the target region as quiescing, no work will be
    routed to the target region unless there is an active affinity
    for that work.  It is desirable for a message to be issued when
    the quiesce is issued, to indicate that the region is no longer
    receiving work unless an affinity exists.
