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.
[GRID]>srvct1 config vip -node racdbnode2
[GRID]>crsct1 get node role config
#Change to root
#u
password: XXXX
[GRID]>crsct1 config -i node role leaf
B.
[GRID]>srvct1 config vip -node racdbnode2
[GRID]>crsct1 get node role config
[GRID]>crsct1 set node role leaf
[GRID]>crsct1 stop crs
[GRID]>crsct1 start crs
C.
[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
D.
[GRID]>srvct1 set vip -node racdbnode2
[GRID]>crsct1 modify node role config
#Change to root
#u
password: XXXX
[GRID]>crsct1 set node role leaf
[GRID]>crsct1 restart crs
