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.

Preventing looping and inefficient rule execution


This recipe gives guidance on how to avoid rule executions that will loop, potentially indefinitely! We'll use an inbound XML and a local RL (Rule Language) fact as an example.

Getting ready

You'll need access to an SOA composite containing an Oracle Business Rules component in JDeveloper to apply this recipe. We'll assume that you have an XSD schema with an input RequestInput containing two strings called input and bonus, and an output ResponseOutput containing a string called output. These aren't efficient, but will serve as an example. We'll step through adding a rule to a composite and creating an RL fact.

How to do it...

To remove potential circular references, perform the following steps:

  1. Open the SOA composite. Right-click on the project, and select Business Rules (Service Components); use the search box if it is not immediately available.

  2. Give the rule a name, and click on the green plus (+) icon to add RequestInput to the Input and ResponseOutput...
