NameServer neighbors
To use NameServer neighbors, you configure multiple NameServers on one or more subnets. For each such NameServer, you specify the instance name of each of the other NameServers that you want to act as a NameServer neighbor. When a client makes a connection request to a specific NameServer, if this NameServer determines that it cannot satisfy the request (usually because it does not recognize the specified application service), it passes the request to all of its NameServer neighbors. The first NameServer neighbor to respond to a client request provides the Unified Broker connection.
You can configure and use NameServer replication and NameServer neighbors together to provide the maximum in connection-level fault tolerance.
