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.

Viewing the memory used using VisualVM for HotSpot


The VisualVM application lets you view real-time JVM data such as memory and thread usage and garbage collection cycles. This recipe will show how to connect to local and remote JVMs in order to view this information.

Getting ready

For this recipe, you will need to have the Hotspot JVM installed on your local machine. We'll use the VisualVM application built in to the JDK 6 release so there is no need to download the available, standalone VisualVM distribution.

We'll attach VisualVM to the WebLogic Administration server to visualize its memory usage at runtime. To do this, you need to ensure that the Administration server is configured to start with the Hotspot JVM.

We will extend the recipe by connecting to a remote Hotspot VM to show the steps required to view remote JVM data.

How to do it…

Perform the following steps to view the memory used by Hotspot, using VisualVM:

  1. Navigate to the domain's home directory:

    %MIDDLEWARE_HOME%/user_projects/domains...
