Config File
In $ORACLE_HOME/network/admin/:
tnsnames.ora
: Each database or service has a unique entry in the tnsnames.ora file, containing the information necessary for clients to connect to the service. The entry consists of a name for the service, the network location of the service, and the name of the database or service that clients must use when connecting to the service. In other words, it resolves service names into network addresses, telling clients how to find the databases.listener.ora
: Is a server-side configuration file that defines the properties and parameters of the listening process, which is responsible for receiving incoming client requests and forwarding them to the appropriate Oracle database instance. In other words, it configures the listener, which is the program that sits on the server and listens for connection requests from clients, telling the server how to listen for client requests.
