Before you start
The Hello World series is for novice developers who want a high-level, hands-on overview of IBM software products. Each tutorial in the series provides simple exercises and step-by-step instructions to familiarize you with the components and use of a particular product. Upon completing a tutorial in the Hello World series you will know enough about the product to begin exploring and using it on your own.
This tutorial uses hands-on exercises to familiarize you with Rational Performance Tester. Step-by-step instructions teach you how to record an automated performance test, enhance the test using built-in data-driven techniques, play-back the test as part of a performance schedule, and evaluate real-time reports to determine the root cause of a performance problem. The maximum estimated running time for the tutorial is three hours.
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.
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.
To effectively evaluate Rational Performance Tester, you will need a realistic Web-based sample application to test. Installing and configuring this application will take some amount of effort. To set up the tutorial environment on your own machine, you must install Rational Performance Tester, WebSphere Application Server 6.0, and the sample application to be tested as well as configure the environment for yourself. Note that the example application for this tutorial is not found in WebSphere Application Server 6.1; you must have access to version 6.0. If you don't have WebSphere Application Server V6.0 installed, download the trial version (look under Previous versions). More detailed setup instructions are provided in the following sections of this tutorial.
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.
- The demos are 800 x 600 pixels. If this is the maximum resolution of your screen or if your resolution is lower than this then you will have to scroll to see some areas of the demo.
