This Application Performance and Tuning course is designed to teach the students how to prevent application performance problems and to improve the performance of existing applications. Students will learn about indexes, table design, locking, and other issues relevant to application performance. This course includes paper exercises and machine exercises designed to reinforce the lecture content.

After completing this course, students will be able to:
  • Design better indexes
  • Determine how to live with the optimizer (avoid pitfalls, help when necessary)
  • Avoid locking problems
  • Use accounting trace information to find significant performance problems in an operational application
