Abstract for MVS System Codes
Purpose of this information
This information describes the system completion codes and wait state codes issued by components, products, and subsystems of z/OS (5650-ZOS). The information helps you interpret and respond to the system completion codes and wait state codes.
System completion codes are also called abend codes.
Who should use this information
- Initialize the operating system and its subsystems.
- Keep the system running correctly.
- Diagnose and correct system problems.
- Diagnose and correct errors in problem programs.
How to use this information
- An introduction to the format of system and user completion codes and of wait state codes
- Descriptions of system completion codes issued by system components, products, and subsystems
- Descriptions of wait state codes loaded during system operation
- Descriptions of wait state codes loaded during operation of a stand-alone dump program
Code descriptions
- Explains why the code was issued
- Identifies the component, subsystem, or product issuing the code
- Describes the actions taken by the system
- Suggests actions that the operator, user, application programmer, or system programmer can take, if appropriate, in response to the code
The system programmer responses assume that the programmer has performed the customary diagnosis described in z/OS Problem Management.
Location of user completion codes
z/OS MVS System Codes does not contain the 4-digit decimal user completion codes that some IBM-provided components, subsystems, or products issue. These codes appear in information for the component, subsystem, or product that issues the codes. Codes issued by installation-provided programs do not appear in IBM® information.
