8.1: Problem determination vs. tuning

This section describes a summary of the difference between problem determination and tuning. Problem determination and tuning are closely related topics, each having the same outcome: a better performing product. You might perceive tuning as a subset of problem determination.

Understanding the difference between problem determination and tuning is important. Knowing when to use tuning and when to use problem determination will save you time.

Problem determination

Problem determination is the process of determining the source of a problem; for example, a program component, machine failure, telecommunication facilities, user or contractor-installed programs or equipment, environmental failure such as a power loss, or user error.

Tuning

Tuning is the process of adjusting an application or a system to operate in a more efficient manner in the work environment of a particular installation.

In other words, problem determination fixes functional problems, while tuning alleviates slow processes.

The WebSphere Performance and Tuning Guide describes the parameters that should be modified to create an optimum product environment.
