Network Setup for Clusters
As part of the zone creation process, you can also cluster zones together, where they are members of a cluster. Access to the client access network for each cluster is achieved through the Single Client Access Name (SCAN) and Oracle RAC Virtual IP (VIP) addresses. The following figure shows a graphical representation of how clusters are accessed through the client access network.
In this respect, access to the clusters that have zones as members is no different than how clusters are accessed when clusters are used on two or more physical computers (each with an Oracle RDBMS instance) to concurrently access a single database.
