I didn't get listener file get installed I have downloaded oracle sql developer to access Remote database. After downloading i couldn't connect to the database. I don't have tns.ora file installed in my system neither do i have oracle_home. Do I need to install oracle database too in order to have tns.ora file in my system.
SQL Developer can connect to Oracle databases without Oracle client and tnsnames.ora.
