02023: System Paging 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:  Identifies when the system paging rate is causing
the System Resource Manager (SRM) to swap tasks.

RATIONALE:  The system paging rate is used by the SRM in
determining under/overcommitment.  When the rate is above the
limit, multiprogramming will be decreased by unilateral
swaps.  Thus, this exception identifies the cause of
unilateral swapping when it occurs.

DEFINITION:  This exception is detected when the system
paging rate exceeds the installation-defined maximum.

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:

**  02023 SYSTEM PAGING RATE EXCEEDS MAX

  EXCDESC2='PAGE RATE=' !! PUT(PAGPSSPG,8.1) !! '/SEC';

END;

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

rate - The maximum rate per second of system paging is
specified.  A threshold rate of 100 would appear as:
