Does anyone know or know how to find the default values for the various memory allocation-related parameters (-Xms, -Xms, -XX:PermSize, -XX:MaxPermSize) for Tomcat version 6?

As far as I can tell the defaults should be the same as for any server JVM. Are you using the default Sun/Oracle JDK, version 6?

If so you could check the default values here:



Of course, if this particular Tomcat install is new to you remember to check the actual JVM parameters using ps auxwwe (if using Linux) and its init scripts in case someone set CATALINA_OPTS or JAVA_OPTS, etc.
