Abstract for MVS™ Diagnosis: Reference

This formation is divided into two sections:

For information about Predictive Failure Analysis, and Runtime Diagnostics, see z/OS Problem Management.

Who can use this information

This information is for anyone who diagnoses software problems that occur on the operating system. This person is usually a system programmer for the installation. This information also contains reference information that is helpful to application programmers who are testing programs.

This information assumes that the reader:
  • Understands basic system concepts and the use of system services
  • Codes in Assembler language, and reads Assembler and linkage editor output
  • Codes JCL statements for batch jobs and cataloged procedures
  • Understands the commonly used diagnostic tasks and aids, such as message logs, dumps, and the interactive problem control system (IPCS)
  • Understands how to search the problem reporting databases
  • Understands the techniques for reporting problems to IBM®

New and less experienced system programmers typically find z/OS Problem Management helpful for learning basic problem determination skills. See z/OS Problem Management.

z/OS Problem Management contains information that is designed to help you avoid potential problems. It also helps you diagnose problems on z/OS®, its subsystems, its components, and problems in applications that are running under the system.

z/OS information

This information explains how z/OS references information in other documents and on the web.

When possible, this information uses cross document links that go directly to the topic in reference using shortened versions of the document title. For complete titles and order numbers of the documents for all products that are part of z/OS, see z/OS Information Roadmap.
