Distributing Virtual
Memory Activity
Virtual memory activity associated with a process occurs by default on the same
volume as the program file used to create the process. You can change the swap
volume used by a process for virtual memory activity by using the
PROCESSSWAPVOL operand of the PARAM command.
Suppose you want a GMM primary process in each CPU of a four-CPU system.
Suppose further that the installation volume is $DATA, and that you want to spread
GMM process virtual memory activity equally across two other volumes, $DATA1 and
$DATA2.
You can meet this objective by including the following GMM process definitions in the
CONFIG file:
PARAM PROCESSOBJECT=$DATA.ZNNM.NGM
PARAM PROCESSCPU=(0,1)
PARAM PROCESSSWAPVOL=$DATA1
PARAM GMMPROCESS=GMM_01
PARAM PROCESSOBJECT=$DATA.ZNNM.NGM
PARAM PROCESSCPU=(1,2)
PARAM PROCESSSWAPVOL=$DATA1
PARAM GMMPROCESS=GMM_02
PARAM PROCESSOBJECT=$DATA.ZNNM.NGM
PARAM PROCESSCPU=(2,3)
PARAM PROCESSSWAPVOL=$DATA2
PARAM GMMPROCESS=GMM_03
PARAM PROCESSOBJECT=$DATA.ZNNM.NGM
PARAM PROCESSCPU=(3,0)
PARAM PROCESSSWAPVOL=$DATA2
PARAM GMMPROCESS=GMM_04
The GMM process pairs in CPUs 0,1 and 1,2 use $DATA1 for virtual memory activity,
and the GMM process pairs in CPUs 2,3 and 3,0 use $DATA2. The changes take effect
after you start the NonStop NET/MASTER MS system.
