2.6 How Oracle TMA TCP for IMS Shuts Down

Once started, TMA TCP for IMS normally executes as a non-ending job, servicing inbound requests from remote systems and outbound requests originated by IMS client transactions.

Normal termination is initiated when a system operator issues the SHUTDOWN command. In response to a SHUTDOWN command, TMA TCP for IMS performs the following tasks.

1. Stops accepting new inbound TCP/IP connection requests.
2. Terminates active inbound sessions.
3. Terminates active outbound sessions.
4. Returns control to z/OS.

   Note:

   Pending or in progress transactions are not allowed to complete prior to the system shutting down.
