    Can't connect to Oracle-Server althought the driver is installed

    Gerhard Graf

      When i try to set up a connection to our Oracle-Server, i get the following message:

      An error occurred while communicating with Oracle.


      Detailed Error Message

      C:\oracle\11.2.0\oci.dll not found

      Unable to connect to the server "~~~~~~.world". Check that the server is running and that you have access privileges to the requested database.



      I have already installed the Tableau.Prep-Oracle driver (the right one for Prep), but this message keeps coming up.

      And the dll can be found in this directory:

      When i connect to the database via Tableau 2018.1, i get no error. I have read/write rights, so there should be no problem.

      How can i fix this error?
