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.

  • You don't need tnsnames.ora or an oracle_home to connect to a remote server. What exactly is the error you get? – a_horse_with_no_name Jul 29 '19 at 12:30
