Chapter 23. Problem determination

This chapter outlines the tools available in WebSphere Application Server that can be utilized for problem determination. We examine and explain the log files that WebSphere uses as well as the trace facility provided in WebSphere. This chapter includes a discussion of which components to trace in given situations, and examples of using a trace. In addition, as of V3.5.2 WebSphere supports the Log Analyzer, which is useful for problem determination. See Chapter 24, “Log Analyzer” on page 975 for detailed information on this tool. Lastly we discuss the Object Level Trace (OLT) debugging facility and provide examples of its use.
