64 | Chapter 3: Installing and Running Oracle
The name Net8 was changed to Oracle Net in Oracle9i, and we will
generally use ???Oracle Net??? in this chapter as a neutral term to apply to
all versions of Oracle networking. The term ???Oracle Net Services??? in
Oracle refers to all the components of Oracle Net, including dispatchers,
listeners, and shared servers; these are explained later in this chapter.
A version of Oracle Net runs on the client machine and on the database server, and
allows clients and servers to communicate over a network using virtually any popular
network protocol. Oracle Net can also perform network protocol interchanges.
For example, it allows clients that are speaking LU 6.2 to interact with database servers
that are speaking TCP/IP.
Oracle Net also provides location transparency??”that is, the client application does
not need to know the server??™s physical location. The Oracle Net layer handles the
communications, which means that you can move the database to another machine
and simply update the Oracle Net configuration details accordingly.
