You can configure two types of NameServer instances, determined by their functions, as the controlling NameServer for a Unified Broker instance:
Local — An instance that runs locally on the host where it is defined
Remote — An instance that references a NameServer defined and running locally on a machine that is remote from the host where the remote instance is defined
When you configure a local NameServer instance, you can set all properties for the NameServer. When you configure a remote NameServer instance, you can only set its location (host and port) properties to identify the local NameServer instance that it references. When you want to start, stop, or obtain status on a running NameServer, you must always perform these actions on a local instance. You cannot start, stop, or obtain status on a remote NameServer instance.
