Oracle Database is supported on Windows Server 2008 and Windows Server 2008 R2 with the 10.2.0.5 release. Use the Oracle Database 10g Release 2 (10.2.0.5.0) for Microsoft Windows Server 2008 and Microsoft Windows Server 2008 R2 media available in the 10.2.0.5 media pack and the Oracle Technology Network site. Do not install Oracle Database on Windows Server 2008 or Windows Server 2008 R2 using the media for Oracle Database 10g Release 2 (10.2) for Microsoft Windows.
To ensure that only trusted applications run on your computer, Windows Server 2008 and Windows Server 2008 R2 provide User Account Control. If you have enabled this security feature, then, depending on how you have configured it, Oracle Universal Installer prompts you for either your consent or your credentials when installing Oracle Database. Provide either the consent or your Windows Administrator credentials as appropriate.
You must have Administrator privileges to run some Oracle tools, such as Database Configuration Assistant, Net Configuration Assistant, and OPatch, or to run any tool or application that writes to any directory within the Oracle home. If User Account Control is enabled, and you are logged in as the local Administrator, then you can successfully run each of these commands in the usual way. However, if you are logged in as "a member of the Administrator group," then you must explicitly start these tasks with Windows Administrator privileges. Refer to "Starting Database Tools" in Oracle Database Platform Guide for Microsoft Windows Itanium (64-Bit) for more information.
