06031: PI Maximum 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
maximum 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
described below:

*
**  06031
**  PI MAXIMUM SEARCH LENGTH EXCEEDS STANDARD
*;
IF ISYMXPIS > PI-search-length
 THEN DO;
  EXCCODE='06031'; SEVERITY='I'; MGMTAREA='PERFORMANCE';
  EXCDESC1=
  'PI MAXIMUM SEARCH LENGTH EXCEEDS STANDARD';
  EXCDESC2='PI MAX SEARCH LENGTH ='
           || PUT(ISYMXPIS,7.2);
  LINK HIT;
END;

    THRESHOLD MODIFICATION:  Modify the value used for the
PI-search-length.
