Oracle Net Services

From Wikipedia, the free encyclopedia

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,^[2] a proprietary networking stack, runs on both client devices and on Oracle database servers in order to set up and maintain connections and messaging between client applications and servers. Oracle Net comprises two software components:

1. Oracle Net Foundation Layer: makes and maintains connection sessions
2. Oracle Protocol Support: interfaces with underlying networking protocols such as TCP/IP, named pipes, or SDP.

[edit] The listener

The listener process(es) on a server detect incoming requests from clients for connection and manage network-traffic once clients have connected to an Oracle database. The listener implements a listener.ora configuration-file to help keep track of names, protocols, services and hosts. Apart from pre-defined and known statically-registered databases, a listener can also accept dynamic service registration from a database.
