Troubleshooting 11
Network Configuration Assistant (NETCA)
NETCA fails, resulting in database creation errors
NETCA fails because the public network, hostname, or virtual IP is not listed 
in the /etc/hosts.equiv file.
Before launching NETCA, ensure that a hostname is assigned to the public 
network and that the public and virtual IP addresses are listed in the 
/etc/hosts.equiv file.
NETCA cannot configure remote nodes or a RAW device validation error 
occurs while running DBCA
This issue occurs when the /etc/hosts.equiv file either does not exist or does 
not include the assigned public or virtual IP addresses.
Verify that the /etc/hosts.equiv file on each node contains the correct public 
and virtual IP address. Try to rsh to other public names and VIP addresses as 
the user oracle.
