title: Alteryx & tableau - OCILogon2 Error: ORA-12514: TNS:listener does not currently know of service requested in connect descriptor
body: <p>I have two database servers Test and Prod. I installed all the oracle client tools required for establishing connections. I am able to connect to both of Test &amp; PROD using basic connection type from SQL developer. Also I am able to connect to the Test environment using Tableau &amp; Alteryx but when I try to connect to PROD it throws TNS listener error(both Alteryx and Tableau). I am using Oracle OCI to connect in Alteryx and basic connection type in tableau. I did not set up any TNS names from the beginning</p>
  
  <p>Oracle server version: 12C
  SQL Developer: 18.4.0.376.1900
  Tableau: 2019.3.4
  Alteryx: 2018.4.5</p>
