Clients use a simple name, called a connect
identifier, in their connect strings. A connect identifier can
be the net service name or the
actual name of the service. For example, sales is the
connect identifier in the following connect string:
CONNECT scott/tiger@sales
During a connection request, the client contacts a naming
method to resolve sales to a connect
descriptor, which the contains destination service information
and the path, or network route, across the network to get to that
service. The destination service is indicated by using its service
name for Oracle8i databases or its Oracle
System Identifier (SID) for Oracle8 or Oracle7 databases. The
network route provides, at a minimum, the location of the listener
through use of a network address.
The client must be configured with the naming methods to use in order to look up connect identifiers. The preferred order of naming methods to use are stored in the sqlnet.ora file.
