Learn Oracle - Naming Methods
Oracle Net provides support for the following mapping methods:
Local Naming
Directory Naming
Easy Connect Naming
External Naming
Local Naming
The local naming method stores connect descriptors, identified by their net service
name, in a local (on the client) configuration file named tnsnames.ora.
Directory Naming
The directory naming method stores connect identifiers in a centralized
LDAP-compliant directory server to access a database service.
Easy Connect Naming
The easy connect naming method enables clients to connect to an Oracle database
server or Oracle DBA machine by using a TCP/IP connect string consisting of a host name and optional port
and service name:
CONNECT username/password@host[:port][/service_name]
For example:
CONNECT scott/tiger@my-server:1521/mydb
The easy connect naming method requires no configuration.
External Naming
The external naming method stores net service names in a supported non-Oracle
naming service. These supported third-party services include:
Network Information Service (NIS) External Naming
Distributed Computing Environment (DCE) Cell Directory Services (CDS)
