I am trying to connect to an Oracle database through Power BI Desktop. I have tried reading through this article, but it doesn't seem to solve my problem.
I am still getting the following error when trying to connect to an Oracle database:
- "The recommended provider ('Oracle.DataAccess.Client') is not installed. You can continue with your current provider, however it has been deprecated and may not work properly."
The following Oracle client has been installed, yet it still does not work.
It's strange Microsoft still has not solved this issue so that all the necessary Oracle-tools automatically gets installed when installing Power BI Desktop.
Hi, @Anonymous ;
These errors might occur if the Oracle client either isn't installed or isn't configured properly. If it's installed, verify that the tnsnames.ora file is properly configured and you're using the proper net_service_name. You also need to make sure that the net_service_name is the same between the machine that uses Power BI Desktop and the machine that runs the gateway.

You might also encounter a compatibility issue between the Oracle server version and the Oracle Data Access Client version. Typically, you want these versions to match, as some combinations are incompatible. For instance, ODAC 12.x does not support Oracle Server version 9.
If you downloaded Power BI Desktop from the Microsoft Store, you might be unable to connect to Oracle databases because of an Oracle driver issue. If you encounter this issue, the error message returned is: Object reference not set. To address the issue, do one of these steps:
-
Download Power BI Desktop from the Download Center instead of Microsoft Store.
-
If you want to use the version from Microsoft Store: on your local computer, copy oraons.dll from 12.X.X\client_X to 12.X.X\client_X\bin, where X represents version and directory numbers.
