I assume that you're referring to the JVM arguments Xms and Xmx. There
isn't a tomcat-specific setting to control JVM memory allocations;
you'll need to read more about that in the java documentation of the
appropriate JVM, but it isn't much more to the arguments than what you
already stated. As far as 'appropriate values' goes, those are
subjective because everyone's application's have different memory
needs. You will have to do some load testing to determine how much
memory your application will need to function properly. If your
application is behavior abnormally and there are OutOfMemoryExceptions
occurring you can also analyze a heap dump from the event to determine
if you have an application problem causing memory issues, or if you
just need more memory.
