5.2.3 Termination

Normal operation continues until a SHUTDOWN command is received. Under normal circumstances, TMA TCP for IMS is terminated by entering an operator SHUTDOWN command (through the outstanding command WTOR).

When a SHUTDOWN command is received and accepted, the following activities occur:

1. The TMA TCP for IMS gateway stops accepting requests for new inbound connections (from remote systems).
2. Active inbound and outbound sessions are terminated without permitting in progress transactions to complete.
3. The Message Log and Server Response Log datasets are closed.
4. The TMA TCP for IMS gateway terminates and returns control to z/OS.
