How to remove or edit existing JVM options in Tomcat?

Question

I want to remove specified JVM options in Tomcat by using commands. I have tried following commands but none of them were able to remove the option. For example, This one removes everything except specified one:

tomcat\bin>tomcat8 //US//tomcat8 --JvmOptions -XX:+HeapDumpOnOutOfMemoryError

This one seems to do nothing also did not throw any error:

tomcat\bin>tomcat8 //US//tomcat8 -JvmOptions -XX:+HeapDumpOnOutOfMemoryError

Is there any way to do this?

Answer 1

You could remove/change the JVM options by editing the Winidows Registry directly.

The java setting is stored within Windows registry, in entry jvm under:

HKEY_LOCAL_MACHINE\SOFTWARE\Apache Software Foundation\Procrun2.0\YourChosenServiceName\Parameters\Java

Please see the snapshot below.
