DFS3608I xxxx SUBSYSTEM REQUIRED EXIT MISSING yyyy, JOBNAME = zzzzzzzz.

Explanation

IMS was not able to finish processing successfully for external subsystem (xxxx). A required exit (yyyy) was unavailable. zzzzzzzz is the name of the job that encountered the problem. JOBNAME is required because more than one region can have connections to the external subsystem. yyyy can be one of the following values:
ID
ID IDENTIFY EXIT
RID
RESOLVE-IN-DOUBT EXIT
SNON
SIGNON EXIT
CRT
CREATE THREAD EXIT
CMP
COMMIT PREPARE EXIT
CMC
COMMIT CONTINUE EXIT
ABC
ABORT AND CONTINUE EXIT
TRTD
TERMINATE THREAD EXIT
SNOF
SIGNOFF EXIT
TERM
TERMINATE IDENTIFY EXIT
SNO
SUBSYSTEM NOT OPERATIONAL EXIT
STE
SUBSYSTEM TERMINATION EXIT
NORC
NORMAL CALL EXIT
ECHO
ECHO EXIT
CMD
COMMAND EXIT

System action

A subsystem connection is not established. If a connection exists, it is terminated in the normal termination sequence, and the task structure (TCB) is collapsed for the control region. If an application is involved, it terminates with abend 3049.

Operator response

Notify the installation personnel about the receipt of this message, then follow the installation action.

Programmer response

Ensure that the subsystem load library is accessible to IMS. IMS provides a DD statement (DFSESL) to alleviate this problem. The external subsystem modules must be in a z/OS authorized library accessible by IMS (that is, JOBLIB, STEPLIB or DFSESL). Use the IMS /START SUBSYS command to restart the failing external subsystem connection when the problem has been resolved. If this action does not solve the problem, then check the External subsystem documentation to determine which exits are provided. The Explanation identifies the required exits.
