MDAC 2.5 SDK - ODBC Driver for Oracle
Patches for the Oracle server products and its client component are required for the proper functioning of several Microsoft products and technologies, including the Microsoft ODBC Driver for Oracle, the Microsoft OLE DB Provider for Oracle, Internet Information Services (IIS), Component Services (or Microsoft Transaction Server, if you are using Windows NT), and so forth.
Note The following instructions may not be completely accurate because the Oracle FTP site is subject to change.
To download the Oracle software patches
Accessing this FTP site from your Web browser might not work. If you experience problems, try using a "traditional" FTP client or use the DOS command prompt.
Note Because Oracle fixes bugs in current versions and then retrofits them to earlier versions using software patches, it is recommended that you download the latest patch available. This is especially true for the Oracle Server Client components. If you have questions about installing these patches, contact Oracle Support.
