The Create Net Service Alias dialog box enables you to create net service aliases in a directory server.
A net service alias is an alternative name for a net service name or database service. A net service alias entry does not have connect descriptor information. Instead, it only references the location of the object for which it is an alias. When a client requests a directory lookup of a net service alias, the directory determines that the entry is a net service alias and completes the lookup as if it is the referenced entry. For example, a net service alias of db1alias can be created for a database service of db1. When db1alias is used to connect to a database service, as in CONNECT scott/tiger@db1alias , it will actually resolve to and use the connect descriptor information for db1 .
There are two main uses of net service aliases:
Use a net service alias as a way for clients to refer to a database service or net service name by another name.
Use a net service alias in one Oracle Context for a database service or net service name in a different Oracle Context. This enables a database service or net service name to be defined once in the directory server, but referred to by clients that use other Oracle Contexts.
