Error while connecting Oracle Database

We are getting the below error,
Connect: A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)

Hi @kiranh,

Check your connection: SERVER/INSTANCENAME
It’s not a slash, it should be a backslash ( \ ).

Best regards,

Below is connection string format
Driver={Microsoft ODBC for Oracle};;Uid=UserName;Pwd=Secret;”
