Dear Linux Admins
I am going to configure 12c R1 RAC on Oracle LINUX 6.9
I am using Oracle's Virtual Box
I have configured 3 network adapters
-
eth0 => Public
-
eth1 => Private
-
eth2 => Internet connectivity
But the problem is , eth1 and eth2 are not detected
# ifconfig -a
eth0 Link encap:Ethernet HWaddr 08:00:27:D7:48:C4

Above output shows eth1 and eth2 are missing.
