Provides an alternate server name for a single database running on a database server.
-sn name
The database server can be configured to listen for more than one server name for a particular database server. Server names other than the real server name are called alternate server names, and are specific to a particular database running on the database server. Clients using the alternate server name to connect can only connect to the database that specified the alternate server name. Alternate server names must be unique on the network; otherwise, the database fails to start. If the database is started in the server command and the alternate server name is not unique, the server fails to start.
