In the field of database computing, Oracle Net Services consists of sets of software which enable client applications to establish and maintain network sessions with Oracle Database servers. Since Oracle databases operate in and across a variety of software and hardware environments, Oracle Corporation supplies high-level transparent networking facilities with the intention of providing networking functionality regardless of differences in nodes and protocols.

Oracle Net, [3] a proprietary networking stack, runs both on client devices and on Oracle database servers in order to set up and maintain connections and messaging between client applications and servers. Oracle Net (formerly called "SQL*Net" or "Net8" [4]) comprises two software components:
The listener
process(es) on a server detect incoming requests from clients for connection - by default on port 1521
[5] - and manage network-traffic once clients have connected to an Oracle database. The listener uses a configuration-file - listener.ora
- to help keep track of names, protocols, services and hosts. The listener.ora
file can include three sorts of parameters:
[6]
Apart from pre-defined and known statically-registered databases, a listener can also accept dynamic service registration from a database.

Oracle Net Manager, a GUI tool, configures Oracle Net Services for an Oracle home on a local client or server host. [8] (Prior to Oracle 9i known as "Net8 Assistant". [9])
tnsping
: determines the accessibility of an Oracle net service.
[10]Oracle software integrating closely with and/or depending on Oracle Net Services includes:
network service name[:] A simple name for a service that resolves to a connect descriptor. Users initiate a connect request by passing a user name and password along with a network service name in a connect string for the service to which they want to connect: CONNECT username/password@net_service_name
Oracle's network interface, Oracle Net, was formerly known as Net8 when used in Oracle8, and SQL*Net when used with Oracle7 and previous versions of Oracle.
By default, the listener listens on port 1521 for clients requiring database access.
The Oracle Connection Manager is a lightweight, highly-scalable program that can receive Oracle Net packets and re-transmit them to a different server. To a client running Oracle Net, the Connection Manager looks exactly like a database server.
Oracle Net Manager enables you to configure Oracle Net Services for an Oracle home on a local client or server host.
In Oracle8, Oracle provided a GUI utility called the Net8 Assistant used to create the various configuration files required for Net8; this utility was renamed the Oracle Net Manager with the Oracle 9i release.
Use tnsping
to determine whether an Oracle Net service can be successfully reached [...] specify a protocol address instead of a net service name to test connectivity to an Oracle Names server or Connection Manager instance.
