IMS messages and codes

IMS issues messages, abend codes, status codes, and return codes in response to events during operation. Programmers, operators, and system support personnel can use these messages and codes to diagnose IMS problems.

These topics provide reference information for the IMS messages that have the DFS prefix, along with their associated codes, as well as for non-DFS prefixed IMS messages that are associated with various IMS components such as: IMS Base Primitive Environment (BPE); IMS Common Queue Server (CQS); IMS Common Service Layer (CSL); Database Recovery Control (DBRC); and IMS Connect. They provide diagnostic reference information that helps programmers, operators, and system-support personnel diagnose problems in IMS. They also provide reference information for all IMS abnormal termination (abend) codes, including analysis, explanation, possible causes, and APAR processing instructions, and provide return, reason, sense, function, and status codes for various IMS components such as: IMS Base Primitive Environment (BPE); IMS Common Queue Server (CQS); IMS Common Service Layer (CSL); Database Recovery Control (DBRC) facility; and IMS Connect. They provide diagnostic reference information that helps programmers, operators, and system-support personnel diagnose problems in IMS.

These topics are the same as those in the following PDF publications, but the content in IBM Knowledge Center is updated more frequently:
  • IMS Version 13 Messages and Codes, Volume 1: DFS Messages (GC19-4240-03).
  • IMS Version 13 Messages and Codes, Volume 2: Non-DFS Messages (GC19-4241-03).
  • IMS Version 13 Messages and Codes, Volume 3: IMS Abend Codes (GC19-4242-03).
  • IMS Version 13 Messages and Codes, Volume 4: IMS Component Codes (GC19-4243-03).

Programming interface information

This information is intended to help programmers, operators, and system support personnel diagnose IMS problems. This information also documents Diagnosis, Modification or Tuning Information provided by IMS.

Diagnosis, Modification or Tuning information is provided to help you diagnose, modify, or tune IMS. Do not use this Diagnosis, Modification or Tuning information as a programming interface.

Diagnosis, Modification or Tuning Information is identified where it occurs, either by an introductory statement to a section or topic, or by the following marking: Diagnosis, Modification or Tuning Information.
