Tomcat 5.5.35 as Windows Service Java Opts

["Smith, Mitchell" <mi...@cwc.com>]

Hi,

I am trying to configure some additional parameters for a tomcat
installation

Tomcat5.5.35
Windows Server 2003

Due to the nature of the WebService to be hosted on this tomcat
installation I would like to increase the Eden heap size.

With my previous Linux Implementations adding -XX:NewSize=1234m to my java
opts worked, however if i try to add this to the service in Windows, the
value appears to be ignored.

It appears in the VM arguments, but the value is not propogated to the Heap
Configurations.

32-bit ?
JVM 32-bit ?

The image appears to have been stripped by the mail server.

If the system and JVM are 32-bit, you only have about 2 GB of addressable space per 
process (even if the system has a lot more RAM in total).  I believe that the JVM may 
ignore the argument if it is too large.
