If the patch is rolling patch it can be applied for each instance one
by one so RAC database has basically no downtime. If patch is not
rolling (or the whole patch set with dictionary upgrade) then it
should be applied on all oracle homes of all instances at the same
time.
We don't have time for it during our outage window so we install it to
another Oracle home and then only switch oracle home and upgrade
catalog.
This was the answer on the first question as I undertsood it. The
second question I don't understand at all.
