You installed the Oracle Grid Infrastructure on a four-node cluster before discussing the
network requirements with the network administrator who was on holiday. You created a
single scan named mydb-scan.myclust.example.com by adding this name to the /etc/hosts
file. As a result, the Grid Infrastructure has four node listeners and node VIP but only a
single SCAN listener and SCAN VIP. The network administrator has returned and modified
the corporate DNS server to associate three IP addresses with the
mydb-scan.myclust.example.com scan name. The SCAN VIPs are on the same network as
the node VIPs. You now must replace the single SCAN VIP and listener with three of each
for high availability purposes and make certain that the SCANs and listeners are active.
Which procedure will do this properly if run as the root user?
A.
srvctl stop scan_listener srvctl stop scan srvctl remove scan srvctl add scan srvctl start
scan srvctl start scan listener
B.
srvctl start scan srvctl start scan_listener srvctl add scan -n MYDB-SCAN . MYCLUST .
EXAMPLE . COM srvctl start scan srvctl start scan_listener
C.
srvctl stop scan_listener srvctl stop scan srvctl remove scan srvctl add scan -n
MYDB-SCAN.MYCLUST.EXAMPLE.COM
D.
srvctl stop scan_listener srvctl stop scan srvctl start scan srvctl start scan_listener
