Java 1.4.2_04 Aggressive Heap on Windows 2000 Server

Question

Hi all
I seem to be having trouble ith the JVM switch of -XX:+AggressiveHeap
I have Tomcat 4.1 running with the following extra JVM options
-server -XX:+AggressiveHeap -XX:+UseParallelGC -XX:+UseAdaptiveSizePolicy -XX:+DisableExplicitGC
Its a quad processor, with 3 gigs of RAM
BUT
The java heap is dying at 128MB of RAm - is there any known issues with AggressiveHeap not allocating sufficient available memory on Windows 2000 Server.
From the docs and white papers, if I read correctly, with a 3Gig RAM systems, the white paper says it will allocate half the available physical ram, i.e. 1.5Gig in this case. I seem to be getting only 128MB though?
Help?
Please

Answer 1

I've worked it out thanks - it was a Tomcat 4.1 as a service oddity...
In Tomcat 4.1, each JVM Option must be entered in the registry as one option per key, e.g.
JVM Option Number 1 -server
JVM Option Number 2 -XX:+AggressiveHeap
and not
JVM Option Number 1 -server -XX:+AggressiveHeap
Hope this is useful to fellow Tomcat users. Oh, and in Tomcat 5, it places all the values into a single key in the registry and works - just for fun I guess ;-)
