Description

This course provides in depth information on how to tune WebSphere, database server, web server and the operating system to extract the last drop of performance. It covers performance tuning methodology, how to detect a bottleneck and common problems and solutions. After taking this class, students will be able to methodically create a stress testing plan and find bottlenecks and resolve them.

The students will perform hands on lab to create test scripts, perform stress test and gather key performance numbers. The class is generic as far as the stress testing tool is concerned. The concepts learned in this class can be used with any tool of choice.
