JBoss Performance Tuning Training

Course#: WA1370

This course provides in depth information on how to tune the JBoss Application Server, and the relevant database server, web server as well as the operating system to extract the last drop of performance. It covers a 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 performance testing plan and find bottlenecks and resolve them.

The students will perform hands on labs to tune JBoss server’s different containers – Web container and the EJB container, and also gather key performance numbers.

Topics
 
  • JBoss Processing Pipeline
  • Data Gathering
  • Monitoring Memory and CPU
  • Performance Tuning Techniques
  • JBoss Problem Determination
  • O/S (AIX/Solaris) tuning tips
  • MYSQL tuning tips
  • JBoss best practices
  • Problem determination techniques
What you will learn
  After completing this course, the student should be able to:
  • Understand the performance testing methodology
    • How to standardize the terminology for better communication.
    • How to tune the JBoss Server – Web and the EJB container.
    • How to measure if a system will meet performance expectations.
  • Identify potential bottlenecks in JBoss applications
  • Analyze application performance with JBoss Tuning Techniques
  • Improve application databases configurations for optimal performance
  • Know how to monitor applications after deployment
Audience
  System Administrators,QA team members, developers, architects, consultants and IT specialists.
Prerequisites
  Good experience with JBoss application development and/or QA. Some introductory JBoss administrative knowledge required. The following course can provide the required JBoss administrative skills. WA1364 - JBoss Application Server v4 Administration
Duration
