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


In this chapter, we'll look at the aspects of SOA Suite that can be tuned when interacting with the backing database. Recipes for tuning the database itself can be found in Chapter 8, BPEL and BPMN Engine Tuning.

As we scale SOA Suite to cope with application load, it is likely that the underlying database will become a performance bottleneck. SOA Suite makes heavy use of the database, storing both the metadata for process instances as well as their payloads. Much of the tuning for the BPEL, BPMN, Mediator, and other components, which we discuss in later recipes, is based around reducing the amount of database I/O that happens. The primary use of the database by SOA Suite is for its "Dehydration Store," which is a phrase used to describe how process instances can be persisted to the database in order to be loaded at a later time. This can be done for a number of reasons: it allows process instances to persist across restarts of the server, and can allow long-running processes...
