I am a student , new to Toad and I would like to seek your help and expertises. I heard my classmates talk about the easiness of using Toad and it is my first time of trying the great product. I have used MongoDB and RMongo in my previous classes. I am trying to use Toad and I am running into a connection problem. I am reading Toad’s article on how to install Oracle client on window machine ( https://www.toadworld.com/platforms/oracle/b/weblog/archive/2017/03/07/oracle-11g-12c-client-install-on-windows-lightweight-and-locked-down ) , and I was succesfully install the Oracle client on my window machine on my C drive at C:\app\client\grego\product\12.1.0\client_1 . However , when I tried to go to the cd C:\app\client\grego\product\12.1.0\client_1\network\admin in order to add my tnsname.ora file ; it said that c:\app directory does not exist.
I have no clue why c:\app directory did not exist in window eventhough the client software was sucessfully installed on C:\app\client\grego\product\12.1.0\client_1 . Please tell me if I miss some important steps or do i need to do any thing in order to create my tnsnames.ora there or any other directory.
