Manage Data: Topology

The Topology tab enables you to delegate domains and provide domain hints.

When an Oracle Names server delegates domains within its region, it creates a hierarchy of Oracle Names servers to serve an administrative region more efficiently. The Oracle Names server effectively creates a new domain when it does this.

Domain hints are useful when an Oracle Names server is getting a lot of requests for services in a particular remote region. Usually, when a Oracle Names server gets a request for a service name in a remote region, it forwards it on to whatever remote Oracle Names servers it knows, who then forwards the request to the root Oracle Names server in its region. The root Oracle Names server will forward the request to the Oracle Names servers which has information on the domain that the request refers to.

If there are a lot of requests for data from a certain remote region, a domain hint can be configured. A domain hint contains the name of the domain and at least one address of an Oracle Names server in that domain. This enables the Oracle Names server to forward the request to a specific address, reducing network traffic is reduced.
