Ideally, programs run forever, error-free, and within their performance targets. However, code failures do occur. When this happens, programmers need problem analysis tools and techniques that help find problems as quickly as possible.
OS/2 Warp Version 4 provides the architecture, tools, and support to help you collect and manage problem determination data. The goal is to get your code back on track (that is, service the code) as quickly as possible.
This chapter introduces the problem analysis elements and techniques that are available to you. The remainder of the book provides details about these elements.
