JBoss AS 5 Performance Tuning

By: Francesco Marchioni, Jason Savod

Overview of this book

Today's organizations need to deliver faster services to a large set of people and businesses. In order to survive this challenge, enterprises need to optimize the performance of their application server along with its components and hardware. Writing faster applications is no longer just an option for your products; it's an imperative requirement, which you cannot ignore. JBoss AS 5 Performance Tuning will teach you how to deliver fast applications on the JBoss Application Server and Apache Tomcat, giving you a decisive competitive advantage over your competitors. You will learn how to optimize the hardware resources, meeting your application requirements with less expenditure.The performance of Java Enterprise applications is the sum of a set of components including the Java Virtual Machine configuration, the application server configuration (in our case, JBoss AS), the application code itself and ultimately the operating system. This book will show you how to apply the correct tuning methodology and use the tuning tools that will help you to monitor and address any performance issues. By looking more closely at the Java Virtual Machine, you will get a deeper understanding of what the available options are for your applications and how their performance will be affected. You will learn about thread pool tuning, EJB tuning, JMS tuning, Enterprise Java Beans, and the Java Messaging Service. The persistence layer and JBoss Clustering service each have a chapter dedicated to them as they are two of the most crucial elements to configure correctly in order to run a fast application. You will also learn how to tune your web server, enabling you to configure and develop web applications that get the most out of the embedded Tomcat web server.

Chapter 5. Tuning the Middleware Services

4th Circle of Hell: Avarice and Prodigality: Those who hoarded possession of the EJB container or squandered resources, forgetting to invoke remove on Stateful Beans.

Tuning the middleware services is a key step to ensure a positive experience for customers running Java EE applications. JBoss AS 5.x integrates all the Java EE 1.5 features and, while this book is being written, release 6 of the application server has gone through the fifth milestone, including most of the new exciting features of Java EE 1.6.

This chapter will cover the following topics:

  • In the first part of this chapter, we will cover Enterprise JavaBeans (EJB), which are a fundamental server side component of Java EE. We will discuss the performance of their main subtypes (Stateless Beans and Stateful Beans) and which factors can enhance or decrease their throughput.

  • In the next part, we will learn about Java Messaging Service (JMS), which has been implemented by means of different...
