Step 4 - Oracle Client Configuration
Learn Oracle - Client Configuration
When a client configured with the same protocol address broadcasts a request for a
connection, the listener on the server machine or Oracle DBA machine brokers the request and forwards it to
the Oracle database.
The client uses a connect descriptor to specify the database it wants to connect to. This
connect descriptor contains a protocol address and a database service name. A
database can have multiple services defined, so a specific one must be specified for the
connection. In the case of the preconfigured database that you installed, there is only
one service, the name of which defaults to the global database name.
