Error - Oracle: ORA-12154: TNS
Am unable to connect to the Oracle Database. The error is - "Oracle: ORA-12154: TNS:could not resolve the connect identifier specified". Can anybody offer a solution. Thanks
Make sure your TNSNAMES.ORA file is updated to your new database in the oracle folder and it will work fine. I had the same issue and couldn't figure out what was happening, turns out the DB Admins changed the database hostname. Went in changed the tnsnames.ora file name to the new database connections and power BI connected with no problem.
