Hi

I'm currently running a Tomcat6 service on Debian Squeeze and spent some time to test various parameters. When I check my settings with ps -ax |grep tomcat I notice that there are always some default parameters. For example: the tomcat starts with Xmx256m (I still don't know where this value comes from) and my custom HeapSpace of 1024m which I've set as CATALINA_OPTS in bin/setenv.sh

This leads into 2 questions:
1. Where does the default value come from?
2. Does ist collide in any way with my custom settings?

Thanks
OK

Look in:

For this line:

I believe variables in here should overide any other settings, however I am not sure.

Hi gdizzle,

I forgot to mention that I've already disabled these values in /etc/init.d/tomcat6. Thats why I said that I don't know where the JAVA_OPTS values come from. If I specify JAVA_OPTS in bin/setenv.sh I can override the default JAVA_OPTS values. But I don't believe that I can override JAVA_OPTS with CATALINA_OPTS because these are two different variables and Tomcat is aware of them. Finally I guess each JVM starts with a build-in default Heapspace. And my conclusion to the existence of both variables is that when ever possible CATALINA_OPTS are used - otherwise JAVA_OPTS (e.g. shutdown).
