You are tasked with managing an Oracle RAC 12cR1 installation, which is using Oracle Flex Cluster.
While analyzing the installation you realize that racdbnode2 should be configured as a Leaf node
instead of a Hub node.
Which commands must you use to determine the cluster node type (role) of racdbnode2 and change
the role to Leaf node of the same node?
A.
Option A
B.
Option B
C.
Option C
D.
Option D
Question seems to be wrong
second step should be crsctl get node role config
https://docs.oracle.com/database/121/CWADD/bigcluster.htm#CWADD92647
https://docs.oracle.com/database/121/CWADD/crsref.htm#CWADD92694
Since there is no crsctl modify node listed in the documentation, I eliminated C as an answer. I think B, it isn’t perfect, but it does not seem to have errors.
Seems like B is correct.
C is not correct. B is also not correct but the answer is closer except that before changing the role we have to log in as root user
So correct answer should be B if it is re-written as:
[GRID]>srvct1 config vip –node racdbnode2
[GRID]>crsct1 get node role config
#Change to root
#u
password: XXXX
[GRID]>crsct1 set node role leaf
[GRID]>crsct1 stop crs
[GRID]>crsct1 start crs
B
