Troubleshooting ORA-12154 requires checking the TNS configuration. Verify the `tnsnames.ora` file on the client machine to ensure the service name or connect identifier is correctly configured and matches the database server's listener settings. Also, confirm the database server is running and accessible from the client machine by checking network connectivity and firewall rules.
