Goal

When adjusting the java options as follows:

-server -Xrs -Xoptimize -verbose:gc -Xms1024M -Xmx1024m -XX:PermSize=16m -XX:NewSize=256m -XX:MaxNewSize=256m

and configuring for this OC4J instance 2 islands each one with 3 processes, does each process then take 1024m so the memory consumed will be 6*1024,
or do all the 6 processes share the 1024m?
