Hi All,

One questions on patching on RAC database. We will be patching our 4 node production RAC this weekend.

The database is in and the patches are a couple of one-off streams patches and not any major patches. Only difficulty we found is that long time, it takes for applying each patches. (Total time around 10 hours).

I was thinking about various backout options.

One is rolling back the applied patches, if something goes wrong.

Also, another plan is to take a backup of ORacle home from the production RAC nodes.

And if we need to backout, just untar the Oracle home backup tar file to the oracle home directory.

Please let me know if you have any suggestions.
