    You can connect Microsoft Copilot Studio to an on-premises Oracle Database by using the Oracle Database connector through the Power Platform On-premises Data Gateway.

     

    This integration allows Copilot Studio to access structured data in Oracle securely and in real time — without replicating or moving the data to the cloud.

    Steps Overview

     

    1. Install the On-Premises Data Gateway

       

      • The gateway acts as a secure bridge between your on-premises Oracle environment and Microsoft cloud services (like Copilot Studio, Power Apps, or Power Automate).


      • You only need one gateway installation to connect multiple data sources or services.



      •  

    2. Install the Oracle Client on the Gateway Machine

       

      • Ensure the 64-bit Oracle Data Provider for .NET (ODAC) is installed — version 11.2 or later.


      • The Windows installer version must be used (the xcopy version isn’t supported).


      • You can verify installation using PowerShell:

         
         
         
        [System.Data.Common.DbProviderFactories]::GetFactoryClasses()
         

        You should see “OracleClient Data Provider” listed in the output.



      •  

    3. Create the Connection in Copilot Studio / Power Platform

       

      • Navigate to Data → Connections → New Connection.


      • Choose Oracle Database, then provide your server name, port, SID or service name, and credentials.


      • Test the connection to validate access through the gateway.



      •  

    4.  

    Supported Versions

     

    • Oracle Database: 9 and later


    • Oracle Data Access Client (ODAC): 11.2 and later



    •  

    Security and Data Residency

     

    • Microsoft only indexes metadata (like table and column names).


    • There is no data movement between systems — each query runs directly against your Oracle instance at runtime.


    • All requests use the user’s authenticated identity, ensuring that existing Oracle access controls remain enforced.
