Hi team,
i have access to an oracle database but for some reason I cannot access the database and keep getting error message stating "Oralce: ORA-12541: TNS: No Listener". I have tried the following as stated other knowledge base
1. Update the tnsname file
2. Update the host information in listener and tnsname
3. uninstall and reinstall the oracle instant client
4. updated the environment variables
Having said the above, I went to verify if my connection from the ODBC driver works fine and I'm able to connect successfully but cannot connect via Data > New Query > Database > Oracle Database and the same applies for ODBC.
Please advise....A!
