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.

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.

The z/OS System Logger is a function provided by the operating system to exploiters running on z/OS. The number of exploiters of this component is increasing, as is its importance in relation to system performance and availability. This IBM Redbooks document provides system programmers with a solid understanding of the System Logger component and guidance about how it should be set up for optimum performance with each of the exploiters. System Logger is an MVS component that provides a logging facility for applications running in a single-system or multi-system sysplex. The advantage of using System Logger is that the responsibility for tasks such as saving the log data (with the requested persistence), retrieving the data (potentially from any system in the sysplex), archiving the data, and expiring the data is removed from the creator of the log records. In addition, Logger provides the ability to have a single, merged, log, containing log data from multiple instances of an application within the sysplex.

This IBM Redbook provides students of information systems technology with the background knowledge and skills necessary to begin using the basic facilities of a mainframe computer. It is the first in a planned series of textbooks designed to introduce students to mainframe concepts and help prepare them for a career in large systems computing. For optimal learning, students are assumed to have successfully completed an introductory course in computer system concepts, such as computer organization and architecture, operating systems, data management, or data communications. They should also have successfully completed courses in one or more programming languages, and be PC literate. This textbook can also be used as a prerequisite for courses in advanced topics or for internships and special studies. It is not intended to be a complete text covering all aspects of mainframe operation, nor is it a reference book that discusses every feature and option of the mainframe facilities. Others who will benefit from this course include experienced data processing professionals who have worked with non-mainframe platforms, or who are familiar with some aspects of the mainframe but want to become knowledgeable with other facilities and benefits of the mainframe environment. As we go through this course, we suggest that the instructor alternate between text, lecture, discussions, and hands-on exercises. Many of the exercises are cumulative, and are designed to show the student how to design and implement the topic presented. The instructor-led discussions and hands-on exercises are an integral part of the course material, and can include topics not covered in this textbook. This book is also offered with a textbook cover instead of a redbook cover in PDF and hardcopy formats.

Mainframe computers play a central role in the daily operations of many of the worlds largest corporations. Batch processing is still a fundamental, mission-critical component of the workloads that run on the mainframe and a large portion of the workload on IBM® z/OS® systems is processed in batch mode. This IBM Redbooks® publication is the second volume in a series of four in which we describe new technologies introduced by IBM to facilitate the use of hybrid batch applications that combine the best aspects of Java and procedural programming languages such as COBOL. This volume specifically focuses on the z/OS batch runtime. The audience for this book includes IT architects and application developers, with a focus on batch processing on the z/OS platform.
