06030: PI Average Search Length Exceeds Standard

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

    SEVERITY:        Impacting     (SEVERITY='I')
    MANAGEMENT AREA: Performance   (MGMTAREA='PERFORMANCE')

    PURPOSE:  Identifies that PI processing may be over-
committed.

    RATIONALE:  An abnormally high number here may represent
resource over-utilization.  This number, combined with the
request rate in the PI pool, indicates whether applications
are taking checkpoints frequently enough.  This number should
be less than one.

    DEFINITION:  This exception is detected when the PI
average search length exceeds the installation-defined 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
