Oracle ODAC 19c Setup Guidance

I have a Windows machine that must talk reliably to an Oracle Database 19c instance. To make that happen I need Oracle ODAC 19c installed alongside the 64-bit Oracle ODBC driver, then a working tnsnames.ora configured so the client can resolve our service name and establish a test connection.

Here is how I picture the engagement: you walk me through (or remotely execute) a clean ODAC 19c installation, ensure the 64-bit ODBC driver is properly registered, and update the PATH and ORACLE_HOME variables if required. Once the software pieces are in place, you will create or edit tnsnames.ora with the host, port, and service information I supply, confirm resolution with tnsping, and demonstrate a successful connect in both SQL*Plus and the Windows ODBC Data Source Administrator.

Deliverables
• ODAC 19c and 64-bit ODBC driver fully installed on Windows
• tnsnames.ora entry tested and working
• Brief note or screen-caps showing each verification step

No other versions are needed—everything should target 19c only. If you are comfortable with Oracle Universal Installer, environment variable tuning, and basic network troubleshooting, this should be straightforward and quick.
