Paging utilization - Tricks

If the paging utilization is sudden high and keeping constant in that place for more than 3 days... then use this method to reduce the paging utilization.


server1:/root # lsps -s
Total Paging Space   Percent Used
      21312MB               28%



server1:/root # chps -d 1 paging00
shrinkps: Temporary paging space paging01 created.
shrinkps: Paging space paging00 removed.
shrinkps: Paging space paging00 recreated with new size.

(THIS COMMAND WILL TAKE DOUBLE SIZE OF PAGING, THAT IS  28X2 TIMES) IF YOU DO NOT HAVE ENOUGH SPACE IN PAGING... DONT RUN THIS COMMAND.




 by decrease 1 pp.....it will create temp paging ... move or reduce usage then recreate
so at end % will become 1 or 2%
 will decrease 1 pp and later add it back after % is reduced

now  add back the 1 pp

server1:/root # chps -s 1 paging00

server1:/root # lsps -s
Total Paging Space   Percent Used
      21376MB               1%

NOTE : Never try this steps, when your paging is more than 50%
