On the right hand side, right-click and select New | String Value. 3 If you use TNSNames.ora it is recommended to use either an environment variable or a registry setting to force the location of the file. This setting is called TNS_ADMIN and is set to the directory/path of the tnsnames.ora file (but should not contain the filename, just the path to it.

A tnsnames.ora change shouldn't require a reboot but some applications will read and parse the tnsnames.ora at startup to be able to present a drop-down list of servers to the user, for example, and will cache whatever was read when the application started up rather than re-reading the file If you are looking for the tnsnames.ora file, please check the TNS_ADMIN environment variable for its location. If it is not set, tnsnames.ora file will be taken from $ORACLE_HOME/network/admin However, this may impact the performance of DataStage jobs that process large amounts of data due to sharing the resources that are configured for MTS. The tnsnames.ora file is located in the following directory by default: $ORACLE_HOME/network/admin or in the location specified by the TNS_ADMIN variable During a recent troubleshooting, we came across a requirement where we wanted to know what all locations does Oracle searches tnsnames.ora ?

For the standard database user, accessing an Oracle database in a standard capacity, the connection is performed via TNS, (Transparent Network Substrate). This requires a running Oracle listener to listen for incoming connections, then connecting to information stored in the sqlnet.ora and the tnsnames.ora files Oracle - Understanding the tnsnames.ora and listener.ora file In the tnsnames.ora file you may specify the IP address of either the host name or the remote server. Most DBAs prefer to use the host name and let Oracle look up the IP address in the hosts file. That way, they don't need to change the tnsnames.ora file if a server relocated to a new IP address The tnsnames.ora file is used to map connection information for each Oracle service to a logical alias.
