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 w

Answer 1

The answer to my own question is, I think, to use tomcat7.exe:

cd $CATALINA_HOME
.\bin\service.bat install tomcat
.\bin\tomcat7.exe //US//tomcat7 --JvmMs=512 --JvmMx=1024 --JvmSs=1024

Also, you can launch the UI tool mentioned by BalusC without the system tray or using the installer with tomcat7w.exe

.\bin\tomcat7w.exe //ES//tomcat

An additional note to this:

Setting the --JvmXX parameters (through the UI tool or the command line) may not be enough. You may also need to specify the JVM memory values explicitly. From the command line it may look like this:

bin\tomcat7w.exe //US//tomcat7 --JavaOptions=-Xmx=1024;-Xms=512;..

Be careful not to override the other JavaOption values. You can try updating bin\service.bat or use the UI tool and append the java options (separate each value with a new line).
