java - How do I increase memory on Tomcat 7 when running as a Windows Service?

Question

I am trying to run Tomcat 7 as a Windows Service (XP and Windows 7).

I see places to set the -Xmx and -Xms jvm args in catalina.bat, but I'm not sure how to do it when using $CATALINA_HOME/bin/service.bat install service-name. I looked around but the best I could find was that I needed to update windows registry key, though I'm not sure which one to edit.

I'm hoping there's an easier way, is there?

Update: I'm not using the windows installer mainly because I'm running multiple instances of tomcat on the same machine but with different ports (for reasons I'd rather not go into here). If I can use the installer with multiple instances using different ports, then I'd like to know how, but regardless, is it possible to do increase the memory on a tomcat windows service without the UI tools that come with the installer?

Answer 1

Assuming that you've downloaded and installed Tomcat as Windows Service Installer exe file from the Tomcat homepage, then check the Apache feather icon in the systray (or when absent, run Monitor Tomcat from the start menu). Doubleclick the feather icon and go to the Java tab. There you can configure the memory.

Restart the service to let the changes take effect.
