  • When SERVICE value is incorrect, Here is an article from tableau which suggests that the ORA-12514 error occurs

  • In order to resolve this issue, find out what the correct SERVICE value is, open the TNSNames.ora file located in your %ORACLE_HOME%\network\admin\ folder. Refer to the steps under ORA_12154 if necessary.
