The information in this book describes First Failure Support Technology and the supporting trace and dump facilities that are used during problem analysis. Note that trace utilities are not part of FFST. The FFST technology provides the tools (functions, commands, and graphical interface utilities) to help you instrument and service your code to take advantage of this technology.
Summary of Functions and Interfaces provides a summary of the functions, commands, utilities, and interfaces that comprise FFST.
Although problem determination can be done, whether or not your code is instrumented, any time taken to instrument code is well spent. By instrumenting your code, you will be able to take full advantage of the FFST, trace, and dump tools if code problems occur.
