Configure keep-alive connection interval
This policy setting allows you to enter a keep-alive interval to ensure that the session state on the RDS host is consistent with the client state.
After a client loses the connection to an RDS host, the session on the RDS host might remain active instead of changing to a disconnected state, even if the client is physically disconnected from the RDS host. If the client logs on to the same RDS host again, a new session might be established (if the RDS host is configured to allow multiple sessions), and the original session might still be active.
If you enable this policy setting, you must enter a keep-alive interval. The keep-alive interval determines how often, in minutes, the server checks the session state. The range of values you can enter is 1 to 999,999.
If you disable or do not configure this policy setting, a keep-alive interval is not set and the server will not check the session state.
