What Is a Connect Identifier?
A "connect identifier" is an identification string of a single set of connection information
to a specific target database instance on a specific Oracle server.
Connect identifiers are defined and stored in a file called tnsnames.ora located
in $ORACLE_HOME/network/admin/ directory. Here is one example of a "connect identifier" definition:
(PROTOCOL = TCP)
(HOST = dba.fyicenter.com)
(PORT = 1521)
(SERVER = DEDICATED)
(SERVICE_NAME = XE)
The above "connect identifier" defines "TNS_XE" with the following connection information:
- The network hostname: dba.fyicenter.com.
- The network port number: 1521.
- The name of the target database instance: XE.
