Oracle JRockit: The Definitive Guide

Overview of this book

Oracle JRockit is one of the industry’s highest performing Java Virtual Machines. Java developers are always on the lookout for better ways to analyze application behavior and gain performance. As we all know, this is not as easy as it looks. Welcome to JRockit: The Definitive Guide.This book helps you gain in-depth knowledge of Java from the JVM’s point of view. We will explain how to write code that works well with the JVM to gain performance and scalability. Starting with the inner workings of the JRockit JVM and finishing with a thorough walkthrough of the tools in the JRockit Mission Control suite, this book is for anyone who wants to know more about how the JVM executes your Java application and how to profile for better performance.

Background


JRockit Mission Control started out as a set of internal tools used by the JRockit team to monitor and tune the JRockit JVM in order to make it a better Java runtime. The early analysis tools were initially not available to end customers. However, after we used the tools to resolve a couple of high profile customer issues, the word started to spread. We realized that customers found the tools useful when tuning and profiling their Java applications, and consequently the tools were made more user friendly, packaged together, and released as the Java tools suite known as JRockit Mission Control.

Today, the JRockit Mission Control tools suite is a set of tools for monitoring, managing and profiling Java applications running on JRockit. It also includes a powerful tool for tracking down memory leaks. The JRockit Mission Control tools can, with very little overhead, retrieve a profile that is a fair approximation of the actual runtime behavior of an application. Most other profilers...
