======Overview======
Many applications needs VNC in order to be installed with a GUI, Oracle doesn't require GUI in order to be installed, but the GUI helps, BIG TIME !!! :)

====Procedures====
Two libraries are needed to install VNC:

  * VNC Server
  * Xterm

<sxh bash>
[root@lparaca install]# yum -y install vnc-server  xterm
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
 * base: ftp.hosteurope.de
 * extras: ftp.hosteurope.de
 * updates: ftp.hosteurope.de
Package tigervnc-server-1.8.0-2.el7_4.x86_64 already installed and latest version
Package xterm-295-3.el7.x86_64 already installed and latest version
Nothing to do
[root@lparaca install]#
</sxh>

The start of the VNC session can be done as follows:


<sxh bash>
[root@lparaca install]# su - oracle
Last login: Tue Jan 23 04:06:07 EST 2018
[oracle@lparaca ~]$ vncserver

New 'lparaca:1 (oracle)' desktop is lparaca:1

Starting applications specified in /home/oracle/.vnc/xstartup
Log file is /home/oracle/.vnc/lparaca:1.log

[oracle@lparaca ~]$
</sxh>


This means, that VNC is open on terminal: 1 or port: 5901.
From the VNC Client, you have to connect to: ServerIP:5901
