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.

Tuning JDBC

Java Database Connectivity API was the first interface used by Java programmers to connect to database systems. Even if many new database persistence methods for Java programmers have been developed recently (for example, Entity, JDO, Hibernate, and many others), most database access code running in today's systems is written as plain JDBC.

The reason for the popularity of JDBC, besides the obvious fact that it was the first API released, is that it does not require any special knowledge to get started with it. Just feed the native SQL to your JDBC interfaces and collect the result.

JDBC tuning follows the same pattern as any tuning process, that is, you should at first measure the performance of your application in production and then evaluate possible corrections. However, it's worth to know some basic tuning techniques, which are available from the outset without sacrificing good design and coding practices.

These basic principles, which are described in the following sections...
