OLE DB services automatically enabled by the IBM OLE DB Provider

By default, the IBM® OLE DB Provider for Db2® databases automatically enables all the OLE DB services by adding a registry entry OLEDB_SERVICES under the class ID (CLSID) of the provider with the DWORD value of 0xFFFFFFFF.
The values of the DWORD value determine the number and type of OLE DB services available.
