The purpose of this document is to provide guidelines for setting up JVMs (Jserv groups/OC4J instances/Managed Servers) for online applications in Apps 11i and R12.

This is supposed to be a generic rule of thumb or a starting point. This document is written based on Sun's JDK. Other platforms, like Linux and HP, can also use pretty much the same parameter. IBM AIX does not have all those parameters and some differences will be pointed. Although there are differences in the java parameters, the concepts presented here should apply to all platforms.

Although this has shown to be sufficient for most of the Apps 11i and R12 installations, some additional tuning may be necessary.
