Transaction code SMICM is used to monitor and administrate the Internet Communication Manager, which sends and receives requests to and from the Internet. The ICM is running on the server. In the Server Overview (transaction SM51) you can see the work process types provided on the server and the entry ICM.
• Sending a Soft Shutdown (With or Without a Restart)
- The ICM tries to send responses to its existing clients, but does not accept any new connections.
• Sending a Hard Shutdown (With or Without a Restart)
- With a hard termination, the process is simply terminated. All existing connections and, of course, all requests are lost.
