With my experience, You would need to hit and try with various connection strings to make it work for your ORacle DB.
Basically, you will have to modify the "Connection String" and need to see which string is best for your version of DB.
NOTE: You may get some more errors like, provider not registered and etc.. Google about them and apply the workarounds provided on your machine.
