I have a new Windows 7 laptop, and I need to install an Oracle client to connect with the 11g database at work. I downloaded the package but it has no installer. Reading through many pages of documentation, it looks like I need to use the Oracle Universal Installer, but I can't find a download for it. What are the steps I need to follow to install an Oracle Client on a new laptop that only has Windows 7 installed on it, but I want to connect to an 11g database on another computer?
I downloaded and expanded the Win 64-bit client from http://www.oracle.com/technetwork/topics/winx64soft-089540.html. Can I make use of a TNSNAMES.ORA file, or do I have to put the fully qualified entry into my tools?
