============================================================================ This is the default directory for Oracle Network and Oracle Client configuration files. You can place files such as tnsnames.ora, sqlnet.ora and oraaccess.xml in this directory. NOTE: If you set an environment variable TNS_ADMIN to another directory containing configuration files, they will be used instead of the files in this default directory. ============================================================================
