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.

Identifying slow-running components with the Enterprise Manager


We can use Oracle Enterprise Manager Fusion Middleware Control to view the slow-performing components of our SOA Suite middleware infrastructure, allowing us to target our performance improvements at those components.

Getting ready

This recipe assumes that you have Oracle SOA Suite installed and running, and are able to generate sufficient load against it to demonstrate any performance problems.

You must have the Oracle Enterprise Manager component installed in your domain, and you will need to know the administration username and password for the domain.

How to do it…

  1. Connect to Oracle Enterprise Manager running on the admin server on the URL http://<hostname>:<port>/em; by default, this will be http://localhost:7001/em if you are connecting from the same host.

  2. Log in to Oracle Enterprise Manager by using your administration credentials.

  3. Open Application Deployments, right-click on soa_infra, and select Performance Summary.

  4. Check that request processing time is not high.

How it works…

Oracle Enterprise Manager is an Oracle product that is used to manage and monitor components of the SOA Suite infrastructure. Some of its features are licensed separately to Oracle SOA Suite. So, if you are unsure, you should check with your Oracle account manager to check whether you are licensed or not to use it.

Oracle Enterprise Manager can be used to manage many components within Oracle SOA Suite, and here we use it to view the performance summary for the SOA infrastructure components. In this instance, we view the request processing time, which tells us how long each request is taking to be processed. It is averaged across a large number of components, so you are really looking to see that it is not higher than usual. This of course requires you to know what usual is, so like all of these statistics, it is worth understanding how the system behaves when there are no performance problems.

There's more…

If you get a 404 error when attempting to connect to the Oracle Enterprise Manager Fusion Middleware Control console, it is likely that you did not add it to your game when you created your domain. You can add it to your domain subsequently by running the configuration manager, selecting your current domain, and extending it to add Oracle Enterprise Manager, although you should be aware that this may overwrite any configuration changes that you have made to the startup scripts.
