I would like to set the size of the JVM’s virtual memory when I launch tomcat 5.0. I think the parameters are -Xms and -Xmx. They Catalina ops I think.

Anyway, is there a way to set these parameters on the MyEclipse preference/TomCat 5.0?

-Xms256m -Xmx256m

did that work for you?

I tried it earlier with the following paramenters: -Xms10m -Xmx100m, and it did not work.

I tried it again after I received your message and it seems to work ok.

Is there some way I can find out what the default settings are?

I want to experiment with changes and observe results, and it would be helpful to know the defaults.

These defaults are set by Tomcat and I believe it is 64mb. The default command line from MyEclipse does not specify any ms or mx setting.

Thanks, for now I will just assume it’s 64MB.

No problem.
