Before then, multiple homes did not work well on NT and most, if not all values, went in ORACLE. With the multiple home option, most values are now stored under the appropriate HOMEx key. Non-home specific values (such as those defining the homes themselves) are kept in ORACLE. This explanation is probably incomplete, as this is only what I have gathered from working with it over the past few years. There may be more caveats as well.
