You can also find performance bottlenecks with an automated scalability test; this is the ultimate goal. However, we ve seen many stress and load tests in our careers, and most of them didn t consider one or several of the following rules:

3. After importing the custom template to a computer and restarting the computer, how could you verify that the appropriate settings were made

In this troubleshooting lab, you will import a template to your computer that simulates a troubleshooting environment by enforcing certain security settings. You will then read a scenario and answer questions. If you have difficulty completing this work, review the material in this chapter before beginning the next chapter. You can find answers to these questions in the Questions and Answers section at the end of this chapter.

Test scalability with real-world data sets. Don t test with a data set that can fit completely into the cache of a hard disk on the database server. Use data that already exists, or use a test data generator to produce test data (for example, TurboData: http://www.turbodata.ca/). Make sure the test data is as close as possible to the data the system will work on in production, with the same amount, distribution, and selectivity. Test scalability with concurrency. An automated performance test that measures the time it takes to do a single query with a single active user doesn t tell you anything about the scalability of the system in production. Persistence services like Hibernate are designed for high concurrency, so a test without concurrency may even show an overhead you don t expect! As soon as you enable more concurrent units of work and transactions, you ll see how features such as the second-level cache help you to keep up performance. Test scalability with real use cases. If your application has to process complex transactions (for example, calculating stock market values based on sophisticated statistical models), you should test the scalability of the system by executing these use cases. Analyze your use cases, and pick the scenarios that are prevalent many applications have only a handful of use cases that are most critical. Avoid writing microbenchmarks that randomly store and load a few thousand objects; the numbers from these kinds of tests are meaningless.

Caution Performing this procedure will import security settings to your computer that might result in loss of network connectivity to your computer. You should perform this procedure only on your test computer. The computer should be a member of a workgroup and not a domain.

To set up your computer for this troubleshooting lab, use these steps. 1. In Windows Explorer, open the Labs folder on the CD-ROM that accompanies this book, locate the 270template.inf file, and copy the file to your desktop. 2. Click Start, and then click Run. 3. In the Run dialog box, type mmc, and then click OK. 4. In the Console1 window that opens, maximize the Console Root window. 5. Click File, and then click Add/Remove Snap-In. 6. In the Add/Remove Snap-In dialog box, click Add. 7. In the Add Standalone Snap-Ins dialog box, click Security Configuration And Analysis, and then click Add. 8. Click Close, and then click OK. 9. In the console tree, right-click Security Configuration And Analysis, and then click Open Database. 10. In the Open Database dialog box, in the File Name text box, type 270.sdb, and then click Open.

system and an SCCM client installed. This enables the SCCM server to discover the target computer automatically, eliminating the need to add it to the site database.

Creating a test environment for the automatic execution of scalability tests is an involved effort. If you follow all our rules, you need to spend some time analyzing your data, your use cases, and your expected system load first. Once you have this information, it s time to set up automated tests. Typically, a scalability test of a client/server application requires the simulation of concurrently running clients and the collection of statistics for each executed operation. You should consider existing testing solutions, either commercial (such as LoadRunner, http://www.mercury.com/) or open source (such as The Grinder [http://grinder.sourceforge.net/] or JMeter [http:// jakarta.apache.org/jmeter/]). Creating tests usually involves writing control scripts for the simulated clients as well as configuring the agents that run on the
