Goal
The following documentation explains how to change system hostname in Oracle Linux 7
There are three classes of hostname: static, pretty, and transient.
Static: is the traditional hostname, which can be chosen by the user, and is stored in the /etc/hostname file.
Transient: is a dynamic host name maintained by the kernel. It is initialized to the static host name by default, whose value defaults to “localhost”. It can be changed by DHCP or mDNS at runtime.
Pretty: is a free-form UTF8 host name for presentation to the user. For example: "user's server"
