Registered visitors to the portal are recorded in the ATG profile repository. The profile repository stores information on each registered user, such as name, gender, and address. The profile repository is installed as part of the Oracle ATG Web Commerce platform, and is used by several different parts of the ATG product suite. For more information on the profile repository, refer to the Configuring the Profile Repository Component section of the Setting Up a Profile Repository chapter in the ATG Personalization Programming Guide. If you are using an LDAP-based profile repository, see the Setting Up an LDAP Profile Repository chapter in the ATG Personalization Programming Guide.
