Oracle SOA Suite 11g Performance Tuning Cookbook

Overview of this book

Oracle SOA Suite 11g forms the heart of many organisations' Service Oriented Architecture. Yet for such a core component, simple information on how to tune and configure SOA Suite and its infrastructure is hard to find. Because Oracle SOA Suite 11g builds on top of a variety of infrastructure components, up until now there has been no one single complete reference that brings together all the best practices for tuning the whole SOA stack. Oracle SOA Suite 11g Performance Tuning Cookbook contains plenty of tips and tricks to help you get the best performance from your SOA Suite infrastructure. From monitoring your environment so you know where bottlenecks are, to tuning the Java Virtual Machine, WebLogic Application Server, and BPEL and BPMN mediator engines, this book will give you the techniques you need in a easy to follow step-by-step guide. Starting with how to identify problems, and building on that with sections on monitoring, testing, and tuning, the recipes in this book will take you through many of the options available for performance tuning your application. There are many considerations to make when trying to get the best performance out of the Oracle SOA Suite platform. This performance Cookbook will teach you the whole process of tuning JVM garbage collection and memory, tuning BPEL and BPMN persistence settings, and tuning the application server. This book focuses on bringing together tips on how to identify the key bottlenecks in the whole SOA Suite infrastructure, and how to alleviate them. The Oracle SOA Suite 11g Performance Tuning Cookbook will ensure that you have the tools and techniques to get the most out of your infrastructure, delivering reliable, fast, and scalable services to your enterprise.

Finding out which JVM you are using


Knowing which JVM you are using is a prerequisite to be able to pick one that might perform better.

Getting ready

You need to have installed WebLogic and the SOA Suite for this, and have access to the startWebLogic script.

How to do it…

To find out which JVM you are using, perform the following steps:

  1. Navigate to the domain home directory.

  2. Execute the startWebLogic script for the operating system you are using. This will be startWebLogic.sh on Linux/Unix environments, and startWebLogic.cmd on Microsoft Windows environments.

  3. Look at the first few lines of the output from the script to see the JVM vendor and version:

How it works…

The startWebLogic script executes the command java –version before starting the server, which prints out the JVM version and vendor. There are two JVMs that ship with Oracle SOA Suite 11g. HotSpot is the JVM originally developed by Sun Microsystems, and the descendent of the original Sun JVM. Oracle acquired this JVM with the purchase of...
