Programming Reference

Any transaction that attempts to use the CICS Interface following a normal or immediate shutdown is rejected with a non-zero return code, indicating the interface is inactive.

After the interface shuts down, the following message is written to the operator’s console and to the CICS Transient Data Queue CSMT:

Never terminate DBCCICS using a CEMT FORCE command.

DBCC must be shut down by using the DSCN transaction to successfully perform shutdown cleanup.

Use of CEMT FORCE can cause transactions to hang or abend and may require a CICS restart before the interface can be used again.

IF the CICS Interface . . . Then . . .
abends the abend is detected and an exit routine obtains control.

The exit routine performs the same processing as normal or immediate shutdown (the exit routine logs off all sessions and informs all users that the interface has abnormally shut down).

terminates in such a way that sessions are still logged on to the Teradata Database the TDP LOGOFF command can be used from the MVS operator console to logoff such sessions.

A CEMT FORCE command may have to be used to terminate Teradata Database transactions that are hung.
