Yes its Windows.

When you say "We generally use only one database per windows server.", you mean one database software installation AND 1 instance? Or multiple instances?

We've got several db instances on most of our windows servers and they run smoothly (minus the occassional Oracle bug!)

Regarding why we would have multiple homes is that it is easier to rollback a patch if necessary. Basically I repoint the Oracle services back to the old Oracle home, and clean up the database components and we're back to the previous version.

You are right in principle.
However, he used windows '\' rather then Linux '/' in the directory list so I assumed Windows. We generally use only one database per windows server. Add to that the fact that he uses separate home for each CPU, so my question is relevant.

Maybe it needed to be: Why use a separate home for each patch level?
