That is indeed the point of RAC - you should be able to turn off nodes and
the traffic will (after a short period) redirect to the other available node(s).
Can you define "a while" and what you mean by 'reboot' and how you're
determining that a node is 'down?' Any logs you have and a broad description
of what it is you're trying to do and what you're doing it on would be helpful
too. Don't forget to include details like whether they are using shared
back-end storage and what type that is (SAN/NAS/DAS?) Many problems with RAC
stem from issues in shared storage.
