Use these options to specify whether the EJB Server is also a name server and whether to enable heartbeat detection.
If a server is not accepting connections, the name server does not return a profile (host:port) information to the client. The name server also detects when a failed server is ready to accept connections again and starts routing client requests to that server.
Click Enable as a Name Server to configure the EJB Server as a name server. If you select this option, you can then set the other Naming Service options described below.
