An important part of configuring your application server JVM is through the use of JVM parameters. Since an application server is based on the Java Virtual Machine (JVM), we can pass certain parameters to the JVM to set specific runtime settings. To view and change the JVM configuration for an application server's process, use the Java Virtual Machine page of the Administrative console.
It is also possible to use the
wsadmin tool with Jython to change JVM configuration through scripting. However, this is beyond the scope of this book.
