Steps:
Configuration:Single-node racServer1: Alice
Server2:Bob
Check which is the master node in the cluster.
[root@Bob]#oakcli show ismaster
If Bob server is the master node,to move the master node services from Bob server to Alice server,
[root@Bob]#oakcli restart oak
Check the master from Bob server,
[root@Bob]#oakcli show ismaster
[root@Bob bin]# ./oakcli validate -a
