Watcher is enabled by default. To manage the Watcher process, new parameters were added to the ics.conf file:
local.watcher.enable = "y": the start program (csservice) attempts to start the Watcher before any other services. If this parameter is set to "n", then the Watcher program is disabled.
service.autorestart = "y": the Watcher automatically restarts stopped services. If set to "n", Watcher does not restart stopped services. If this parameter is set to "n" , Watcher still monitors the services and sends failure or non-response error messages to the console and the cal_svr_base/data/log file.
local.autorestart.timeout = "600": the default time within which a second server failure triggers Watcher to stop trying to do a restart.
local.watcher.port: the default port is "49994"; however, if you have Messaging Server, it will also be listening on this port and will be in conflict with Calendar Server. To avoid possible conflict, it is safer to choose a different port for Watcher to listen on.
