While CRS-IUA can run without installing Oracle Recommendations On Demand, you will need to install it to see personalized recommendations on the CRS-IUA homepage. Once installed, CRS-IUA provides the shopper with personalized recommendations. If you choose not to install Oracle Recommendations On Demand, you will still see personalized content on the homepage provided by content targeters.
Three Commerce Reference Store Sites
Commerce Reference Store provides three sites in its out-of-the-box configuration: CRS Store US, CRS Store Germany, and CRS Home, each with a different skin. CRS-M and CRS-IUA provide a site switcher for switching between CRS Store and CRS Home. These sites are also available in Spanish. The German store is not yet supported by CRS-IUA.
