Identify three best practices for applying asmdeactivationoutcome es on Exadata Database
Servers and Exadata Storage Servers?
A.
Backing up database servers and storage cells is not recommended before performing planned
maintenance.
B.
Database server updates can be rolled back using the the “yum downgrade” procedure.
C.
Bundle patches do not require testing before being installed on a production system.
D.
It is recommended that Exadata systems with Data Guard configured use the “Standby First”
patching approach.
E.
Patching should never be interrupted due to a connection drop. It is therefore recommended
that you use VNC or the screen utility.
F.
Before patching cells in a rolling manner, you must check asmdeactivationoutcome
amModestatus and make sure that cells on all disks are online and that disks can be deactivated.

Data Guard Standby First Patch Apply
Patches can be applied to the standby database
before the primary database
Available in 11.2.0.2 BP1+ and 11.2.0.1 BP7+
E
Use either VNC or screen to connect to the server you’re patching
from

When changing the flash cache mode on a rolling basis, the grid disk attribute asmDeactivationOutcome must be yes, and the asmModeStatus attribute must be online for all grid disks on the current cell before moving to the next cell. To check the grid disk attributes, use the following command:
LIST GRIDDISK ATTRIBUTES asmDeactivationOutcome, asmModeStatus
