Environment:
Each node requires at least Two 2 NIC cards one for Public IP and other for Private interconnect.
Node1 : racnode1.ukatru.com
Public IP Address : 192.168.2.52(racnode1.ukatru.com)
Virtual IP Address : 192.168.2.54(racnode1-vip.ukatru.com)
Node2:racnode2.ukatru.com
Public IP Address : 192.168.2.53(racnode2.ukatru.com)
Virtual IP Address : 192.168.2.55(racnode2-vip.ukatru.com)
We need 15GB disk on both nodes to install oracle Cluster software,ASM home and Database home.
