The high availability services provided by Oracle Clusterware are used to protect Oracle
resources, such as RAC database instances, RAC database services, and other
components of the Oracle Grid Infrastructure, and non-Oracle resources as well. Which two
statements are true about the high availability capabilities of Oracle HA services?
A.
ASM instances may be failed over if fewer than three nodes remain in the cluster, so that
there are always at least three ASM instances available.
B.
HA services will only fail over a resource upon failure of the node where the resource
was active.
C.
If a node fails, then all resources that were active on that node will be failed over to a
surviving node if any exists.
D.
RAC databases may have their instances failed over in some cases.
E.
If a node fails, then cluster resources that were active on that node may be failed over to
a surviving node if any exists, but local resources are not failed over.
B: is incorrect, because resource could be failover to another node after resource failure, it is not necessary node failure then resource failover to another node.
Correct answer are: C,E.
