1.2 Managing User Accounts with User Account Control on Windows Server 2008 and Windows Server 2008 R2

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.

To run a Windows shortcut with Windows Administrator privileges:

1. Click the Start menu button.

2. Navigate to Programs, then to Oracle - HOME_NAME.

3. Right-click the name of the command or application you want to run, then select Run as administrator.

To start a command prompt window with Windows Administrator privileges:

1. On your desktop, create a shortcut for the command prompt window. An icon for that shortcut appears on the desktop.

2. Right-click the icon for the newly created shortcut, and specify "Run as administrator."

When you open this window, the title bar reads Administrator: Command Prompt. Commands run from within this window are run with Administrator privileges.

1.3 Oracle Database Client Installation Types

You can choose one of the following installation types when installing Oracle Database Client:

• Instant Client: Installs only the shared libraries required by Oracle Call Interface applications that use the Instant Client feature. This installation type requires much less disk space than the other Oracle Database Client installation types.

  Included in the Instant Client installation is Instant Client Light. You may want to use this version of Instant Client if your applications generate error messages in American English only. The advantage of using Instant Client Light is that it has a much smaller footprint than regular Instant Client. Hence, your applications use less memory.

• Administrator: Enables applications to connect to an Oracle database on the local system or on a remote system. It provides tools that let you administer an Oracle database.

• Runtime: Enables applications to connect to an Oracle database on the local system or on a remote system.

• Custom: Enables you to select individual components from the list of Administrator and Runtime components.
