FQDN setup in SLE 12
 
Dear Experts,
I corrected entries in /etc/hosts file for FQDN setup. Do i need to run any command or any post steps so that FQDN take place.

By "take place" I suppose you mean "be effective". What effect is the FQDN supposed to have on your system?

/etc/nsswitch.conf normally configures domain name lookup to first check /etc/hosts. For example on my Ubuntu 16.04:
Code:
hosts:          files mdns4_minimal [NOTFOUND=return] dns
"files" means /etc/hosts.

I don't think you have to do anything, but to be certain, check /etc/nsswitch.conf.

a quick way to check is hostname -f.
Also, a quicker way to set fqdn (minus the domain discovery/lookup) is to use the handy hostnamectl uttility.

You posted FQDN questions already:
https://www.linuxquestions.org/quest...dn-4175679578/

Even more odd that your profile lists you as a "SAP Technical Consultant", working for a consulting firm, and you're unfamiliar with basics???
