IBM Course Code: WA715
This 3-day course teaches students how to tune WebSphere Application Servers for improved performance.
In this course, students learn about performance tuning methods and best practices that apply to both the application server environment and the Java EE application. These methods and tools for load testing, monitoring, and tuning can be applied to various WebSphere components such as the application server's Java Virtual Machine (JVM), connection pools, and general runtime environment.
Lectures cover topics such as performance tuning concepts and tasks, tools for load testing, monitoring server performance, best practices for tuning the JVM and connection pools, and application profiling.
Hands-on lab exercises provided throughout the course give students practical experience using tools to generate user loads on an application and monitor key performance metrics such as response time and throughput. Students also learn how to gather information from WebSphere's built-in performance advisors and how to use this information to tune, test, and monitor sample Java EE applications.
What You'll Learn
- Apply performance tuning methods to WebSphere Application Servers
- Perform load testing using the Rational Performance Tester (RPT)
- Monitor application server performance using WebSphere and the IBM Support Assistant (ISA)
- Monitor and tune the JVM for optimum throughput and response time
- Monitor and tune connection pools for optimum performance
- Implement best practices for general WebSphere runtime performance
- Use the Rational Application Developer to profile and tune Java EE applications
