      Hi,

      I am facing issue in connecting to Oracle database from Tableau Desktop 2018.3.2 version.  I have installed Tableau oracle driver (2018.3) as well as set up DB connection details in tnsnames.ora.  But still facing the issue.  it is throwing below error.  Attached are the details with screenshots.  Could anyone please help me in debugging this issue.

       

      An error occurred while communicating with Oracle.

      Unable to connect to the server. Check that the server is running and that you have access privileges to the requested database.
      Oracle database error 12154: ORA-12154: TNS:could not resolve the connect identifier specified

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

       

      Thanks,

      Prasanna
