Neighboring NameServers
|
A list of selected NameServers to which this NameServer can forward connection requests for application services that are not registered with it (that is, the application service name is unknown). The list contains all NameServer instances defined in the management console, initially with none selected.
To make a NameServer a neighboring NameServer, select the unselected NameServer to highlight it. You can select as many NameServer instances as you want to be neighboring NameServers. Each neighboring NameServer thus appears highlighted in the list.
To remove a NameServer from the list of neighboring NameServers, select the already-selected NameServer to remove the highlight.
The setting of this property is optional. When a NameServer receives a request for an application service name that is unknown and there are no neighboring NameServers specified, the NameServer sends a message to the requesting client indicating that the application service is unknown. When such a NameServer has neighboring NameServers specified, it forwards the request to each of the neighboring NameServers. The first neighboring NameServer that has the application service name, and responds to the connection request, provides the specified connection to the client.
