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 size of the thread stack


Every thread in your Java process has its own stack. The size of this stack can be controlled via the -Xss setting.

Getting ready

You will need to have Oracle SOA Suite 11g installed for this recipe. This command is the same whether you're using the Hotspot or the JRockit JVM.

How to do it…

Perform the following steps to configure the size of the thread stack:

  1. Navigate to the domain's home directory:

    cd %MIDDLEWARE_HOME%/user_projects/domains/soa_domain/
    

    Replace soa_domain with the relevant domain, as required.

  2. Within the bin folder, you will see a number of scripts. Depending on your platform you will need to edit a different file—setSOADomainEnv.cmd on Windows; setSOADomainEnv.sh on Linux. Note that it is a good idea to make a backup of these files before editing them.

  3. Open the file and locate the following section. Note that I have manually placed the @REM comment; your file will not contain this line:

  4. At the end of the DEFAULT_MEM_ARGS and PORT_MEM_ARGS lines...
