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.

Ensuring automatic database statistics gathering is enabled


As with many SOA Suite components, the BPEL and BPMN engines make a lot of use of the database. Ensuring that the database statistics are updated regularly, will ensure that the optimizer picks the correct plan for accessing the underlying database tables.

Getting ready

You will need database administration access to the database being used for your Oracle SOA Suite 11g applications.

How to do it...

Follow these steps to ensure the database statistics generation task is enabled:

  1. Log in to the database, and open an SQL prompt.

  2. Execute the following SQL query:

    exec dbms_auto_task_admin.enable;

How it works...

The database optimizer uses the most recent database statistics to determine its plan (index lookup, table scan, and so on) for each SQL statement that is executed. Having up-to-date statistics is therefore vital to ensure that the correct plan is selected, and that the database operates as fast as possible. Oracle recommends that automatic...
