 | /etc/system parameters:lgrp_mem_pset_aware=1default random policy applies only to lgroups with a process' processor set.
Each JVM was run in its own processor set containing two cores (one chip).Each JVM was given 32 Mbyte pages with the ppgsz command.Each JVM was placed in the FX priority class with the priocntl command.
