Changing the DEP Setting

Operating Systems: Windows XP, Windows 2003.

Under Windows 2003 and Windows XP operating systems, DEP (Data Execution Prevention) is turned on by default for all Windows programs and services. Before you run the Oracle BI Infrastructure installer, turn off the Data Execution Prevention setting for all programs and set for only essential Windows programs and services in order for certain Oracle Business Intelligence components to install successfully. This procedure is necessary for the installer to complete.

When running the Oracle BI Installer on Windows 2003 or Windows XP operating systems, the installer will direct you to disable DEP. After the installation has completed, the Data Execution Prevention function can be changed back to the original setting.

To change the Data Execution Prevention setting (Windows 2003 and XP only)

1. Depending on your operating system settings, use one of the following methods:
   • Windows XP menu: Go to Start > Control Panel > System > Advanced > Performance (Settings) > Data Execution Prevention.
   • Windows Classic menu: Go to Start > Settings > Control Panel > System > Advanced > Performance > Data Execution Prevention.
2. Switch DEP to Turn on DEP for essential windows programs and services only.
3. Reboot the machine.
4. After reboot, start the Oracle BI installation.
