I was thinking of installing 10 Tomcat instances, each running its own JVM with up to 2 Go RAM.

I hope I will get rid of it by setting java maxpermsize to 2 Go for each Tomcat instance, while I currently use 1 Go on my current server. Is this correct or do I need to set other parameters which may be useful to solve this issue?

When will JRockit be available for Java 7?
A: It won't. As we explained last year we are merging JRockit and HotSpot into one single JVM. JDK 7 contains the first release of this converged JVM, where one of the first steps was to start removing the PermGen concept. Future JDK 7 updates will complete the PermGen removal, as well as add more visible features from JRockit.
