The Monitor Server heartbeat mechanism causes Monitor Server to shut itself down when it detects that Adaptive Server is no longer running. Before automatic shutdown occurs, Monitor Server writes the following message in its log file:
Adaptive Server seems to be down. Shutting down Monitor Server.
If clients remain connected to Monitor Server, Monitor Server can not shut down gracefully. You can ignore an abnormal termination in this case.
The -T1 parameter in the Monitor Server start-up command bypasses the heartbeat mechanism. If you use this option on start-up, Monitor Server does not shut down when Adaptive Server stops.
