The maximum availability requirements for a new system include a provision for eliminating, wherever possible, planned downtime caused by provisioning software patches. The other DBAs on the team have never handled this requirement before and ask you to help specify a rolling patch capability for a six-node RAC database.
What action would you recommend?
A.
Invoke OPATCH, which does rolling patches automatically.
B.
Suggest a shared cluster file system for the Oracle Installation to facilitate Rolling Patches.
C.
Check the PATCH_NUMBER/etc/config/inventory file for text containing true.
D.
OPATCH should be invoked with the minimize_downtime option to allow patches to be applied to one instance at a time while all other instances are functional.
E.
OPATCH should be invoked with the rolling option to allow patches to be applied to each instance by shutting the first and then applying the patch, shutting the second and then applying the patch, and so on, until five instances are shut and patched. When the sixth is shut down, the first five may be restarted and then the patch is applied to the sixth instance, which is then restarted.
