In the high availability services’ provided by Oracle Clusterware are used to protect Oracle
resource such as RAC database instances, RAC database services, and other components of the
Oracle Infrastructure, and non-Oracle resources as well.
Which two statements are true about the high availability capabilities of Oracle HA services?
A.
RAC databases may have their instances failed over in some cases.
B.
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.
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.
If a node fails, then cluster resources that were active on that node may be failed over to a
E.
surviving node if any exists, but local resources are not failed over.
F.
HA services will only fail over a resource upon failure of the node where the resource was
active.
A is wrong. the sentence is inaccurate
B is wrong. ASM does not have to be 3
C is wrong. local resources do not failover
D is right.
E is right.
So D.E. are correct
