Using the Instant Messaging Watchdog Process

Instant Messaging includes a watchdog process, which monitors the Sun Cluster agent, and restarts the services that become unavailable for some reason (such as server lockup, crash, and so forth). In the event that you configure the watchdog process, and an Instant Messaging component stops functioning, the watchdog process shuts down then restarts the component.
