06004: Message Processing Rate Below Standard

    FILE:            IMS System Activity
    SAS FILE NAME:   DETAIL.IMSISY01
    SOURCE LOCATION: sharedprefix.MICS.SOURCE(DYIMSEXC)

    SEVERITY:        Warning       (SEVERITY='W')
    MANAGEMENT AREA: Performance   (MGMTAREA='PERFORMANCE')

    PURPOSE:  Identifies the time period during which the
message processing rate fell below the installation standard.

    RATIONALE:  While not necessarily bad, an abnormally low
message processing rate may indicate potential resource over-
commitment or non-optimum class/priority scheduling scheme.
If the number of messages waiting to process is high and the
message processing rate is low, a problem may exist.

    DEFINITION:  This exception is detected when the number
of messages processed between system checkpoints falls below
the installation-defined limit and the messages waiting to
process is above the co-limit.

    EXCEPTION STATEMENTS:  The SAS statements identifying the
exception situation and describing the condition are stored
in the source member named in SOURCE LOCATION and are
