Explanation:
* Example, Basic Format of tnsnames.ora File
net_service_name
(DESCRIPTION
(ADDRESS=(protocol_address_information))
(CONNECT_DATA
(SERVICE_NAME=service_name)))
* This tnsnames.ora file is a configuration file that contains net service names mapped to connect descriptors for the local naming method, or net service names mapped to listener protocol addresses.
A net service name is an alias mapped to a database network address contained in a connect descriptor.
A connect descriptor contains the location of the listener through a protocol address and the service name of the database to which to connect. Clients and database servers (that are clients of other database servers) use the net service name when making a connection with an application.
