We have seen your posting.Actually we are also facing certain problem with the JVM heap size.We are working on tomcat 5.0.19 .We want to change the heap size setting .When I tried to make a change in Jprobe profiler heap size setting it is working there perfectly.But in jmeter testing again the previous heap size is taken .How can I change the heap size and the most important question is where I have to put the command.
In certain site I have seen the command given below.

set JAVA_OPTS = -server -Xms512m -Xmx512m -XX ermSize=32m -XX:MaxPermSize=64m
Shall I use this command.If yes where I have to put this? Is it in catalina.bat?

Please help me..

Thank you.

Setting JAVA_OPTS in catalina.bat should work for Tomcat started as an application.
I agree. Here's the link:
