support determined that at this time, rolling patch upgrade for RAC is =
not possible. At some point, both/all sides have to be down.

Subject: Re: Q: RAC and non-RAC databases on same servers
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
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
This was the answer on the first question as I undertsood it. The
second question I don't understand at all.

You can also have separate oracle homes relinked with/without RAC =
When you do a patch do you patch everything at the same time, e.g. all
RAC nodes and all their shared homes? Did patching influence your
decision for same Oracle home?
