Uninstall Oracle Client


I’m new to Toad and so is for Oracle Database. I have installed Oracle Client (not Instant Client) to use with Toad for Oracle. But while I’m trying to connect to my work database asking for tnsnames.ora and sqlnet. Anyone know why they are not installed together with the client? I have read through a few articles and tried to work with Instant client as well but no luck. This is my first question.

My second question is I installed the oracle client twice and now i see 2 clients. There were no deinstaller(deinstall folder) anywhere. Is there a way to uninstall the client from my machine?

Those are user file where you create entries/aliases for you database. So when you say connect to ORCL the client software knows where the database is, server, ports, etc.

You’re going to need to learn about this - this is basic Oracle 101 setup stuff.
