Scott, the JAVA_OPTS parameter are used to pass different startup &
configuration options to the Java Virtual Machine. Most commonly it's
probably used to speficify the RAM used by the VM and to fine tune your
GC (Garbage Collection) settings. There are both standard and
non-standard options.

Sorry I mispoke when I said it's not started in a batch file. What I
meant was that tomcat is running as a service that comes in the tomcat
installer app.

Hi,
It's for everything under the Tomcat instance, since one Tomcat instance
is one JVM, no matter how many Hosts or webapps you have on it.

They are all sharing one JVM and it's resources. Java knows nothing of

People set the minimum so that it's allocated on startup. That's faster

The Sun JRE distributions typically don't include a server VM, so
"-server" will give an error. You'll have to download the JDK, and run
the JRE that is embedded within it (.../j2sdk1.4/jre

There must be an error message somewhere. Either in catalina.out or on the console.
Put a pause in at the end of catalina.bat so it stays on screen when you try to start
tomcat.

Howdy,
Yeah, what's going on is limited familiarity with unix syntax. Use
single or double quotes of your JAVA_OPTS (or any other environment
variable) includes spaces, e.g. JAVA_OPTS='-Da=b -Dc=d'.
