02001: Total 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:  Excessive paging indicates overcommitment of
memory.

RATIONALE:  The total paging rate (non-swap, non-VIO page-ins
and page-outs, swap pages in and out, and VIO pages in and
out) reflects the sum of all actual page transfers between
real memory and auxiliary storage.  When real memory is
overcommitted, excessive paging results and this exception
can identify such periods.

DEFINITION:  This exception is detected when the sum of
non-swap non-VIO paging, swap paging, and VIO paging rates
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:

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

rate - The maximum rate of paging per second is specified. A
rate threshold of 500 would appear as:
