Multiple NameServers can cooperate to resolve a client connection. If one NameServer becomes unavailable, another can take its place, thus providing connection-level fault tolerance. When you configure and use NameServers with connection-level fault tolerance, each requesting client uses the Unified Broker connection provided by the first responding NameServer and ignores the rest.

You can configure two types of connection-level fault tolerance:

• NameServer replication
• NameServer neighbors
