Hi Erman,

We have identified the below file has wrong entry with the help of our blog "http://ermanarslan.blogspot.in/2014/11/linux-setting-hostname-fqdn-or-short.html"

[oraprod@0i ~]$ cat /proc/sys/kernel/hostname
0i
[oraprod@0i ~]$

can we change this file without any service restart or can you please suggest if anything is wrong

Thank you

Your hostname is wrong.
Change your hostname.
Use hostname command for this.
Also ensure your hostname is written in /etc/hosts file..

You need to follow standard Linux documents to change your hostname.
But, if you have applications/databases running on this OS, you need follow application/database specific hostname change documentation as well.
