The maximum estimated running time for the tutorial is three hours.

Objectives
After completing this tutorial you should understand the basic functions of Rational Performance Tester and be able to use it to discover and analyze performance problems in your applications.

Prerequisites
This tutorial is for testers new to test automation and unfamiliar with Rational Performance Tester. As you are taking the tutorial, you can practice the steps yourself if you have access to the environment the tutorial requires. If you don't have access to the environment, you can still read the tutorial and view the animated demos. You just won't be able to try the steps for yourself. The easiest way to access the tutorial environment is through the Rational Performance Tester online trial system created for the tutorial. The trial system uses the Citrix Access Platform to provide you with a connection from your workstation to a remote server running Rational Performance Tester, WebSphere Application Server 6.0, and the sample application to be tested. If you choose to set up the tutorial environment on your own machine, please use the Hello World: Rational Performance Tester (for downloadable trial code) version of this tutorial that is written for this purpose. In order to view the animated demos for the tutorial you must enable JavaScript in your browser and install Macromedia Flash Player 6 or higher.

Animated demos
If this is your first encounter with a developerWorks tutorial that includes animated demos you might want to know a few things about them: • Demos are an optional way to see the steps described in the tutorial done for you. To view an animated demo, click the given Show me link and the demo will open in a new browser window. • Each demo contains a navigation bar at the bottom of the screen. Use the navigation bar to pause, exit, rewind, or fast-forward portions of the demo. Rational Performance Tester Page 2 of 26
