Question

Discuss Disconnected mode and how it carries a query text to the server? hi

Expert Solution

Step 1

Disconnected mode:

The disconnected mode is the mode in which the connection is established only when the connection is required.
The established connection automatically closes when all the server calls are performed and it waits for other server calls before establishing the connection.
The database which is used during the time of connection establishment remains open but the connection gets closed after the server calls gets finished.
This disconnected mode is used when server resources are to be saved for further use.
This mode is mostly used during working in an unstable networks.
This mode requires additional time for the authorization during the time of connection establishment.
