Java Startup Params

[rajesh.shanmugam]

My java server process startup script defines startup params as JVM_SERVER_ARGS="-server -Xms128m -Xmx3072m".

However when the server is started it grabs all available (3GB) of memory. We would like to establish
some memory baselines to help manage the need for allocating more memory for the server. sp we need
the server to only start with the minumum and grow as needed.

Below is a current java env:

Java Runtime Name: Java(TM) 2 Runtime Environment, Standard Edition
Java Runtime Version: 1.4.2 1.4.2.05-040917-22:45-IA64N IA64
Java Runtime Vendor: Hewlett-Packard Company

What startup params should we be using?
