The COMMTIMEOUT option specifies how long the server waits for an expected client message during an operation that causes a database update. If the length of time exceeds this time-out, the server ends the session with the client. You may want to increase the time-out value to prevent clients from timing out. Clients may time out if there is a heavy network load in your environment or they are backing up large files.
The COMMTIMEOUT server option is used for non-administrative sessions. See the ADMINCOMMTIMEOUT option for administrative client sessions.
You can update this server option without stopping and restarting the server by using the SETOPT command.
