Which two statements are true concerning Oracle 12c Clusterware-managed application VIPs? (Choose two.)
Correct Answer: B,D
Explanation/Reference:
Explanation:
B: Oracle 11.2 introduced appvipcfg utility for creating VIPs. From the GRID_HOME/bin directory run the appvipcfg command to create the application VIP. Oracle Clusterware assigns this VIP to a physical server in the cluster and will migrate the VIP to a surviving node in the cluster in the event of a server failure.
Example: appvipcfg create -network=1 -ip=192.168.20.111 -vipname=MyTestVIP -user=grid D: While you can add a VIP in the same way that you can add any other resource that Oracle Clusterware manages, Oracle recommends using the script Grid_home/bin/appvipcfg to create or delete an application VIP.
Incorrect Answers:
E: When a node dies in an Oracle RAC cluster, the Virtual IP (VIP) fails over to a different node.
Upon node failure application VIP fails over to a surviving node along with the protected application. It is the Application VIP that is used for accessing the application, thus in case of failure the application will be highly.
