This parameter allows you to assign a unique name to the database instance on a workstation in the NetBIOS LAN environment. This nname is the basis for the actual NetBIOS names that will be registered with NetBIOS for a workstation.
Since the NetBIOS protocol establishes connections using these NetBIOS names, the nname parameter must be set for both the client and server.
Client applications must know the nname of the server that contains the database to be accessed. The server's nname must be cataloged in the client's node directory as the "server-nname" parameter using the CATALOG NETBIOS NODE command.
If nname at the server node changes to a new name, all clients accessing databases on that server must catalog this new name for the server.
