Preface
Oracle SOA Suite 11g forms the basis of the SOA infrastructure for many organizations. While there is a wealth of information on administering SOA Suite applications already available, there is very little independent information available regarding performance tuning. With the chief goal of software and hardware vendors being to sell more licenses and hardware, the topic of getting the most from your existing investment often falls by the wayside. This book aims to address that by giving clear, concise, and simple recipes that will help you identify performance bottlenecks in your application, and then resolve them.
We work from the ground up, starting with how to identify common SOA Suite 11g performance problems and introducing the tools that you need, and working up the stack through JVM tuning and application server tuning, before covering the BPEL, BPMN, and mediator stacks. Finally, we have chapters on application design and deployment considerations.
What this book covers
Chapter 1, Identifying Problems, starts out by looking at some of the common performance problems that can occur in the Oracle SOA Suite applications, and how to identify them. We look at using a variety of tools to understand what is going on inside the JVM, and to identify the particular resource bottleneck that is causing poor performance.
Chapter 2, Monitoring Oracle SOA Suite, looks at how we can use the VFabric Hyperic tool from VMWare to monitor the performance of our SOA Suite infrastructure, and what metrics we should be keeping an eye on.
Chapter 3, Performance Testing, looks at using the Apache JMeter tool to solve performance problems, by triggering them.
Chapter 4, JVM Memory, starts right at the bottom of the Oracle SOA Suite 11g stack. We look at how JVM memory is allocated, and how you can increase and decrease the memory available to your application, as well as other JVM tuning tips. The low-level areas of Oracle SOA Suite are often overlooked, so we cover the basics of Java memory management in enough detail to give those unfamiliar with it sufficient background to understand what they need to be concerned about.
Chapter 5,
