Howdy, No, I don't mean JPDA_OPTS: those are for debugging. CATALINA_OPTS is the environment variable, and one (good) place to set is is in $CATALINA_HOME/bin/catalina.sh. You can also set it in other scripts that start / stop tomcat, etc.
I always thought the internal documentation in Catalina.sh was sufficient. Basically, CATALINA_OPTS will be passed to the java runtime as-is. So if you say CATALINA_OPTS='-Xmx200m', -Xmx200m will be passed to the java runtime, telling it to give you 200MB max on the heap as opposed to the default 64MB. The java.sun.com site has documentation on all the java runtime options. -Xmx is just the beginning if you want to seriously tune your memory / GC performance.
