in SQL Server Reporting Services by 11 12 19

I am using SQL Server Reporting Services (SSRS), and I am using Report Builder to create a report from Oracle database. So I created a new report and I added a new data source with OLE DB as a Connection Type, and then I clicked on Build button to configure the connection properties with Oracle Provider for OLE DB.

How to configure Oracle Data Source in SSRS Report Builder

I provided the server name and the UserName and Password correctly but when I clicked on Test Connection button, I got the below error:

Unable to connect to Data source
The OraOLEDB.Oracle provider is not registered on the local machine

The OraOLEDB.Oracle.1 provider is not registered on the local machine

Why I got this error and How I can configure Oracle Data Source in SSRS Report Builder?

You get this error "The OraOLEDB.Oracle provider is not registered on the local machine" because the Oracle Data Access for Oracle Client is not currently installed on the current local machine.

Important Note:
- If you are using Microsoft Report Builder or Power BI Report Builder with versions before 15.7.01678.0001, you have to install the 32-bit Oracle Data Access for Oracle Client (ODAC-32 bit) to be able to connect to Oracle DB as a data source through the Oracle Provider for OLE DB.
- If you are using Power BI Report Builder version 15.7.01678.0001 and later, you should install the 64-bit Oracle Data Access for Oracle Client (ODAC-64 bit).
For more details, Please check Oracle Connection Type (SSRS & Power BI Report Server)
