What drivers are need to source an Oracle system from SSIS

In order to connect to Oracle in SSIS you will need to first  install the Oracle client software for Windows, and then you use the OLE DB provider in SSIS to connect to Oracle.  FYI, the Microsoft Data Access Components (MDAC) that is installed includes a 32-bit OLE DB provider for Oracle to access an Oracle source system.  However, even though the OLE DB provider is installed, you cannot use it until you install a second component, which is the Oracle client software.   When you install the Oracle client software, Oracle also includes an OLE DB provider that can be used to access an Oracle source, but there are some minor differences.  If you plan to connect to Oracle with a native 64-bit connection, you have to use the Oracle-written OLE DB provider for Oracle because the Microsoft-written OLE DB driver for Oracle is available only in a 32-bit mode. Make sure you also install the right 64-bit Oracle client (Itanium IA64 or X64) if you want to connect to Oracle in native 64-bit mode.

Note:
The Oracle Data Access Components (ODAC) for Windows with Oracle Developer Tools for Visual Studio are a set of Windows and .NET data access drivers and tools. They include support for .NET, COM, and ODBC data access; Microsoft Visual Studio tools for developing Oracle database applications; ASP.NET providers; and .NET stored procedure support. ODAC provides comprehensive client support for advanced Oracle database functionality, including performance, high availability, and security, among other features. It is tightly integrated with Visual Studio and Windows to provide a seamless development experience for Windows developers.
