DFS3611W EXTERNAL SUBSYSTEM xxxx CONNECTION TERMINATED RC=y
Explanation
The daughter task control block (subtask TCB) attached for subsystem xxxx terminated.
Reason
code y, a single character value, indicates the
cause of the termination, represented by one of the following codes:
- Reason code
- Meaning
- B
- The IMS external subsystem daughter task (TCB attached for each connected subsystem) terminated abnormally. Some of the abend conditions can prohibit the invocation of the exit.
- C
- The external subsystem notified IMS that it is terminating in a quiesce fashion. IMS ensures that new connections are not established and permits existing ones to terminate normally.
- D
- The external subsystem notified IMS that it is terminating abnormally (catastrophic). IMS ensures that new connections are not attempted and terminates existing ones.
- E
- The connection between the subsystems is being quiesced by IMS. IMS does not shut down, but remains available. The termination of the connection is the result of the IMS /STOP command, a bad return code from an exit, or a missing required exit.
- F
- The connection between the subsystems terminated because the IMS termination service exit was started by an external subsystem exit, and allowed the external subsystem code to request that the connection be terminated.
System action
IMS continues normal termination processing.
Operator response
The external subsystem can be restarted using the /START command.
Programmer response
Take one of the following actions based
on the reason code:
- Reason code
- Meaning
- B
- The external subsystem TCB terminated. A spin-off memory dump is created for debugging purposes if the spin-off memory dump facility is active. Determine the cause of the abend, and take corrective action.
- C
- The external subsystem quiesced by IMS terminated. No action required.
- D
- The external subsystem terminated abnormally. Determine the cause of the shutdown of the external subsystem (that is, forced shutdown command). The external subsystem should provide adequate problem determination material.
- E
- The connection stopped. No action is required.
- F
- The connection terminated internally. An external subsystem exit instigated the termination of the connection and provided adequate problem determination information by the external exit.
