Hi,
You can take PRVF-0002 : could not retrieve local node name error when you install Oracle database 12c R2.
If you take PRVF-0002 : could not retrieve local node name error , you should check /etc/hosts and /etc/sysconfig/network file.
These files content should be like below. If not you should change it.
[root@MehmetSalih ~]# vi /etc/hosts [root@MehmetSalih ~]# [root@MehmetSalih ~]# [root@MehmetSalih ~]# cat /etc/hosts 127.0.0.1 localhost.localdomain localhost 192.168.63.63 MehmetSalih.localdomain MehmetSalih [root@MehmetSalih ~]# [root@MehmetSalih ~]# cat /etc/sysconfig/network NETWORKING=yes HOSTNAME=MehmetSalih.localdomain # oracle-database-server-12cR2-preinstall : Add NOZEROCONF=yes NOZEROCONF=yes [root@MehmetSalih ~]#
