02014: Total Swap Rate Exceeds Max

FILE: Paging Activity File
SAS FILE NAME: DAYS.SCPPAG01
SOURCE LOCATION: prefix.MICS.USER.SOURCE(DYRMFEXC)

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

PURPOSE:  The total swap rate can identify periods of
resource overcommitment.

RATIONALE:  The total swap rate is the sum of the different
swapping rates.  While swapping is expected in a TSO system,
in a batch system excess swapping occurs when the resources
are overcommitted.  This exception identifies the total swaps
and thus can be used to trigger investigation of the actual
type of swap occurring.

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:

**  02014 TOTAL SWAP RATE EXCEEDS MAX
*;
RATE=(PAGTOSWP/DURATION)*3600; /* CONVERT TO HOURLY RATE */
IF RATE GT  rate THEN DO;
  EXCCODE='02014';SEVERITY='I';MGMTAREA='PERFORMANCE';
  EXCDESC1='TOTAL SWAP RATE EXCEEDS MAX';
  EXCDESC2='SWAP RATE=' !! PUT(RATE,5.1) !! '/HOUR';
  LINK HIT;
END;

THRESHOLD MODIFICATION:  The user should modify the rate
value according to the following convention:

rate - The maximum rate of swaps per hour is specified.  A
threshold rate of 13000 swaps per hour would appear as:

RATE GT 13000
