listener.ora file

A configuration file for the listener that specifies the following:

• Listener name

• Protocol addresses it is accepting connection requests on

• Services (database or non-database service) it is listening for

The listener.ora file must reside in one of the following locations:

1. The directory specified by the TNS_ADMIN environment variable If the TNS_ADMIN environment variable is not defined as a variable on Windows NT, it may be in the registry.

2. The node's global configuration directory. For Sun Solaris, this directory is /var/opt/oracle. Windows NT does not have a central directory.

3. The $ORACLE_HOME/network/admin directory on UNIX or the ORACLE_HOME \network\admin directory on Windows operating systems.

Note: Oracle9i and Oracle8i databases do not require identification of the database service because of service registration. However, static service configuration is required if you plan to use Oracle Enterprise Manager to monitor the database.
