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.

Setting the new size


Getting the new size correct is probably the single biggest thing that can be done to prevent poor garbage collection performance.

Getting ready

This recipe assumes that you are starting WebLogic using the startWebLogic or startManagedWebLogic scripts. If you are using the node manager or some other mechanism, simply apply the startup parameter to the relevant place. You will need the file system permissions to edit the WebLogic start scripts for this recipe.

This recipe assumes that you are using the HotSpot JVM, and if you are using JRockit, see the There's more… section of this recipe, for the parameter you need.

How to do it...

To set the HotSpot heap memory's new size, perform the following steps:

  1. Navigate to the domain's bin directory:

    cd %MIDDLEWARE_HOME%/user_projects/domains/soa_domain/bin
  2. Open the setSOADomainEnv.cmd or setSOADomainEnv.sh script in a text editor.

  3. Locate the following lines for a Windows system:

    SET DEFAULT_MEM_ARGS=%DEFAULT_MEM_ARGS% -XX:PermSize=128m...
