Abstract for MVS Diagnosis: Reference

This information is divided into the following sections:
  • The System Reference section provides system reference material useful for diagnosing system problems. It also contains pointers to other documents that contain more information.
  • The Component Reference section consists of component-specific information that describes diagnostic tools and information available for that component.

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.

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.
