06026: Scheduling 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
scheduling fell below the installation standard.

    RATIONALE:  While not necessarily bad, an abnormally low
scheduling rate may indicate a potential resource over-
commitment.  It is possible that only transactions favored in
the class/priority scheduling scheme are being processed or
that long running programs are dominating the system.  If the
scheduling rate is low and there are messages waiting to
process, it is likely that a problem exists.

    DEFINITION:  This exception is detected when the
scheduling rate exceeds the installation-defined limit.

    EXCEPTION STATEMENTS:  The SAS statements identifying the
exception situation and describing the condition are stored
