CICS, IMS, and z/OS abends

Use this topic to investigate abends from CICS, IMS, and z/OS .

CICS abends

A CICS abend message is sent to the terminal, if the application is attached to one, or to the CSMT log. CICS abend codes are explained in the CICS Messages and Codes manual.

The CICS adapter issues abend reason codes beginning with the letter Q (for example, QDCL). These codes are documented in IBM MQ for z/OS messages, completion, and reason codes

IMS abends

• A normal abend.
• An IMS pseudo abend, with an abend code such as U3044 resulting from an error in an ESAF exit program.
• Abend 3051 or 3047, when the REO (region error option) has been specified as "Q" or "A", and an IMS application attempts to reference a non-operational external subsystem, or when resources are unavailable at the time when a thread is created.

An IMS message is sent to the user terminal or job output, and the IMS master terminal. The abend might be accompanied by a region dump.

z/OS abends

During IBM MQ operation, an abend might occur with a z/OS system completion code. If you receive a z/OS abend, see the appropriate z/OS publication.
