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.

Introduction


JVM manages memory for us so that we can focus on writing our applications. It is pretty good at it too, but it cannot fully optimize its behavior while running programs. To help it, we can give it explicit rules to follow as well as hints on how to operate. Unfortunately, the number of options available for these hints and rules is wide ranging and not always fully documented.

In this chapter, we will explore some of the options available to us and look at how we can monitor the effect they have on your SOA Suite installation. This will allow us to analyze its behavior at runtime and monitor the effect of our applied tuning options. We will look at options for the HotSpot and JRockit JVMs (for more details on making a selection between the two, see the Using the Oracle JRockit JVM recipe in Chapter 6, Platform Tuning end parenthesis.

Memory management is a combination of art and science—more is not always better, and so, selecting your memory settings should always be performed...
