OMS server - oel6-node01.localdomain
Target Server oel6-rac01.localdomain

Add entry of new server in /etc/hosts of oms servers

[oracle@oel6-rac01 oracle]$ cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.189.111 oel6-rac01.localdomain oel6-rac01
192.168.189.101 oel6-node01.localdomain oel6-node01

You can ignore this warning for now and later run root.sh through root user manually.

To overcome this error update /etc/hosts file of target host with details of oms host

[root@oel6-node01 ~]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.189.101 oel6-node01.localdomain oel6-node01
192.168.189.111 oel6-rac01.localdomain oel6-rac01

Deployment is completed now run root.sh and after that click done.
