All,
One of our customers has recently purchased a Quad Processor Mac OS X
(v10.4 Server) for their Tomcat server. The machine has 8 gigabytes
of RAM. The application they are running is very large and extremely
complex, containing well over 100 pages. They are using Tomcat
v5.5.7. The JVM is version 1.4.2.
I need a bit of assistance with how to set the Java OPTS so that the
memory is fully optimized and all processors are used. I have done
some reading, but the advice is, honestly, all over the map. My
current settings are:
JAVA_OPTS="-Djava.awt.headless=true -XX:+UseParallelGC -Xms512m -
Xmx2048m -server"
Using Apple's Activity Monitor, the maximum amount of 'real' memory I
could see was 700 megabytes; while the maximum amount of virtual
memory was 2.3 gigs. In fact, once I reached 700 megabytes of 'real'
memory, the 'out of memory' error was returned.
Thank you in advance.
