I’m new to Oracle.
I’m using Toad editor to connect the Oracle DB.
(my machine is Windows 2003 server 64bit)
What component\client I need to install just for enabling the connection to the oracle? (I don’t want to install an Oracle DB – just a client).
Can you please refer me to the right client? (couldn’t find it in the Oracle homepage)
A page you are viewing contains quite a few links. Choose the "Microsoft Windows (x64)" one and click "See All" link. It will open a new page with many products - you should select "Oracle Database 11g Release 2 Client (18.104.22.168.0) for Microsoft Windows (x64)".
Or, check the Instant Client (as suggested by @rski).
