Book Description
IBM® Problem Determination (PD) Tools consists of a core group of IBM products that are designed to work with compilers and run times to provide a start-to-finish development solution for the IT professional. This IBM Redbooks® publication provides you with an introduction to the tools, guidance for program preparation to use with them, an overview of their integration, and several scenarios for their use. If an abend occurs during testing, Fault Analyzer enables the programmer to quickly and easily pinpoint the abending location and optionally, the failing line of code. Many times, this information is all the programmer requires to correct the problem. However, it might be necessary to delve a little deeper into the code to figure out the problem. Debug Tool allows the programmer to step through the code at whatever level is required to determine where the error was introduced or encountered. After the code or data is corrected, the same process is followed again until no errors are encountered. However, volume testing or testing with multiple terminals is sometimes required to ensure real-world reliability. Workload Simulator can be used to perform this type of testing. After all of the tests are completed, running the application by using Application Performance Analyzer can ensure that no performance bottlenecks are encountered. It also provides a baseline to ensure that future enhancements do not introduce new performance degradation into the application. This publication is intended for z/OS® application developers and system programmers.

Book Description
IBM WebSphere Application Server for z/OS V6 is a complex product made up of many components. This IBM Redbooks publication focuses on the problems that you can experience with WebSphere for z/OS. It is intended for system programmers and administrators who need to identify, analyze, and fix problems efficiently so that they can deliver good support for the WebSphere environment. In Part 1, we provide an overview of problem determination methodology, what skills you need, where to find information about related topics, and how to communicate with IBM when a problem occurs. In Part 2, we describe the most common problem symptoms. Flow charts guide you through the problem analysis process step by step. Individual tasks and questions help you filter out irrelevant facts and find the problem area, so that you can identify the type, source, cause, and possibly a solution. In Part 3, we identify possible problem areas and arrange them into four phases that correspond with WebSphere for z/OS life cycle stages. We explain how to analyze the problems and provide valuable hints and tips for avoiding them. In Part 4, we provide means and tools for problem determination such as commands, logs, dumps, traces, and diagnostic tools. We describe other tools that can ease the day-to-day tasks and prevent problems. We also explain where to get these tools, show you how to use them, and provide examples. Please note that the additional material referenced in the text is not available from IBM.
