Starting with the Oracle 10.2.0.4.0 release, Oracle added the Oracle Configuration Manager Registration form as a part of the patchset setup. This tool allows you to associate your configuration information with your Metalink account. This tool lets you link your service requests with the pre-collected configuration data gathered from the current Oracle Home.
If you are planning to use this tool, you must have available the Oracle Support account information, which comprises of the Customer Support Id (CSI), your Metalink Account Username and password, and the country where this CSI is valid. When checking the box in the registration form, a window with the "Terms of Use" is displayed. Make sure you read and understand it. Once you are ready, accept the "Terms of Use" and fill in the required form information.
