I am attempting to connect Tableau to Oracle, and have the correct server name and access. I also have the TNSNAMES.ORA file in the appropriate (I think) locations, and have set up an environmental variable pointing to this location. Regardless, everytime I attempt to log in, I receive the "TNS Names could not resolve the connect identifier" error. I have two other programs that connect to Oracle just fine on this machine. Can anyone suggest what may be the issue? I'm on Tableau desktop 7.0.
