Oracle TOAD in read-only mode

I'd like to use TOAD in read-only mode to run queries on an Oracle DB in read-only.

I've read that you should copy the file readonly.lic over toad.lic.

What about the file FullToad.lic?

If anyone could tell me what is the difference between toad.lic and FullToad.lic it would be great (for ex开发者_如何学Pythonample: should I copy readonly.lic to both toad.lic and FullToad.lic?).

The safest thing to do would be to create an Oracle User with query only privileges.
