ASE Performance and Tuning

Length: 5 Days
Prerequisites:  Solid understand of SQL, Prior knowledge and experience working with Sybase ASE. Our "Introduction to SQL"and
Introduction to Sybase ASE provide a solid base for this course


Overview

To get the best performance from a high-performance vehicle, you'll likely need to tune the engine and application. Before you can begin
tuning a high-performance engine you need to understand its internals and how they work. what to tune and when to tune it. This course
teaches students how Adaptive Server a high-performance engine works. Topics cover when and what to tune to achieve the best database
performance.

Key Benefits:  When you complete this course you learn how to Analyze and Solve Subtle Performance Problems. You will leave ready to
work with a Performance Team. This course also provides a solid understanding of Sybase Internals.
