Issues with connection to Oracle Database data source in Power BI Desktop RS May 2026

No, it's wrong assumption. When IFILE is used in tnsnames.ora, Power BI Desktop RS May 2026 gives connection error. But when IFILE replaced with actual TNS descriptions, it gives "ORA-01017 (invalid username/password)" error. Only rollback to January 2026 version completely resolves these issues.
