Hi All,
One questions on patching on RAC database.
We will be patching our 4 node production RAC this weekend.
The database is in 10.2.0.3.0 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.
Thanks,
