Hi, All,

I recently patched our 2-node RAC (10.2.0.2 on RHEL AS 4 update 4) to 10.2.0.3. I got the impression that you can do rolling upgrade in a RAC environment, until I dig into the patch installation document and found out that you can do rolling upgrade on the clusterware part but not on the RAC database part. Fortunately we can afford the service to be down for a couple of hours.

My question is: is there a way to keep your RAC database up while you patch it? RAC itself doesn't really provide 24x7 High Availability? Any comments?

Thanks,
-Li
