Setting up a connection to Oracle on Mac

Question

Trying to get connection to Oracle DB from my Mac. I use this tutorial: http://www.toadworld.com/products/toad-mac-edition/b/weblog/archive/2013/07/02/setting-up-a-connection-to-oracle-on-your-mac.aspx

I've done till this command: Sudo chgrp –R wheel /Library/Oracle

When I try it gives me an error: chgrp: –R: Invalid argument

What is the problem and how to fix it?

Thank you in advance!

Answer 1

I have done it with JDBC. I didn't use Oracle client.
