PRVF-0002: could not retrieve local node name

Error Message:

While starting runinstaller for the installation of oracle database 12.2.0.1 on OEL 6 86x64, I encountered this "PRVF-0002: could not retrieve local node name" error.

Cause:

Finally, I found the cause that we have an incorrect entries in the "/ets/hosts" file.

[root@server1 ~]# hostname
server1.dbacentral.com

[root@server1 ~]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain
::1         localhost localhost.localdomain
192.168.1.45       server1.oracle.com         server1
[root@server1 ~]#

The hostname of my linux machine and the information in the "/etc/hosts" file is different. Here my hostname is server1.dbacentral.com, but have an entry like server1.oracle.com.

Solution:

Verify the hostname of your machine by using the following command.

[root@server1 ~]# hostname
server1.dbacentral.com
[root@server1 ~]#

Verify the information of your server in "/etc/hosts" file. You should have same fully qualified ostname and IP Address.

[root@server1 ~]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain 
::1         localhost localhost.localdomain
192.168.1.45       server1.dbacentral.com server1
[root@server1 ~]# 

Try to ping the server using fully qualified hostname.

[root@server1 ~]# ping server1.dbacentral.com
PING server1.dbacentral.com (192.168.1.45) 56(84) bytes of data.
64 bytes from server1.dbacentral.com (192.168.1.45): icmp_seq=1 ttl=64 time=0.073 ms
64 bytes from server1.dbacentral.com (192.168.1.45): icmp_seq=2 ttl=64 time=0.05

Now, Start the runInstaller again.

[oracle@server1 ~]$ ./runInstaller
