At the command line, type the following:
imadmin refresh |
This command stops the server, multiplexor, Calendar agent, cluster agent, and watchdog, terminates all end user connections, and disconnects any inbound and outbound servers configured.
If the watchdog is running, imadmin brings the watchdog down first, and then stops the server and/or the multiplexor. Then starts the watchdog which reads the configuration file and starts the Instant Messaging server and/or multiplexor as necessary.
