Directory naming is one of the primary naming methods used to resolve a connect identifier to a connect descriptor that the client uses to connect to a database. Directory naming stores connect identifiers and their connect descriptors in an LDAP-compliant directory server. The connect identifiers are stored under an Oracle Context subtree that contains entries for use with Oracle software.
An end user enters a connect string that includes the connect identifier in the following format:
CONNECT username/password@connect_identifier
In the following example sales is the connect identifier that is looked up in the directory:
CONNECT scott/tiger@sales
The connect descriptor returned to the client includes the:
Protocol address location of the listener
Service name of the database
The client uses the protocol address information to connect to a listener. The listener, configured with the same address information, receives the request. If the listener is listening for requests to the same database service as specified in the connect descriptor, a connection is granted.
For directory naming to happen, configure a directory server for Oracle Net Services features, and configure clients to access the directory.
