Who Should Use This Book
This guide is intended for server administrators, J2EE applications developers,
network administrators, and evaluators.
This guide assumes you are familiar with:
Before You Read This Book
Application Server can be purchased by itself or as a component of Sun JavaTM Enterprise System (Java ES),
a software infrastructure that supports enterprise applications distributed across
a network or Internet environment. If you purchased Application Server as a component of Java ES,
you should be familiar with the system documentation at http://docs.sun.com/coll/1286.1.
How This Book Is Organized
Chapter 1, Overview of Application Server Performance Tuning explains general concepts and processes for tuning Application Server.
Chapter 2, Tuning Your Application describes
programming practices and application configuration settings to achieve maximum performance.
Chapter 3, Tuning the Application Server
covers how to configure the application server for best performance and reliability.
Chapter 4, Tuning the Java Runtime System
covers how to configure the Java Virtual Machine to work optimally with the Application
Server.
Chapter 5, Tuning the Operating System
covers how to configure the operating system to work optimally with the Application
Server.
Chapter 6, Tuning for High-Availability
covers how to tune the high-availability database (HADB) used for storing persistent
session state for use with the Application Server. It also discusses how you can configure
the high availability features of Application Server for your application.
