As you know, some oracle DB components need be installed under GUI interface.
Please advise which is a free best linux client Terminal emulator that can be easy configured a linux GUI interface for DBA?
I do not think putty is a good linux GUI interface tool.
A terminal emulator and X Window GUI are different things. You can have a terminal emulator in a graphical desktop environment, but you cannot display GUI in a terminal.
Putty is just a SSH client and terminal emulator (VT) and can be used with X-forwarding to display remote GUI applications (Linux), provided you are have a X Window server installed and running on your local computer, e.g. Xming Server for Windows.
Perhaps you will find the free version of http://mobaxterm.mobatek.net/ useful. It is a single application based on Cygwin that allows you run GUI applications from your remote Linux system.
Alternatively, use VNC. You can run VNC in several modes, either to open an existing remote desktop connection, start a new desktop connection, or run a minimal X windows server, such as TWM that does not require you to install or run a graphical user desktop on your remote Linux server. If you are interested in VNC, perhaps check the following: https://community.oracle.com/thread/2456580. You can also tunnel VNC through SSH if your network firewall prevents communication.
Then perhaps MobaXterm as previously mentioned will be useful. It's free and a single application (1 file) that does not need complex installing or understanding the process of running a remote GUI app. I cannot speak much for its terminal abilities, but If you are mainly interested in running a remote GUI, such as DBCA or NETCA that should do.
Thanks very much. I will learn this tool.
Yes. I need tool that is in running my client window and generate a GUI interface is used to operate DBCA or NETCA and oracle install tool and configure RAC and data guard.
I will feedback MobaXterm experience in my window testing
I guess you mean you are NOT able to. Well, what exactly are you doing?
If I remember correctly, all you have to do is to open mobaXterm on your PC, then establish a ssh session with X forwarding and run your X app. Remember, you must not set any DISPLAY variable because ssh will take care of it and you cannot use the su command because it will break xauth authenticaton.
So simply open mobaxterm:
ssh -X oracle@remote_ip
make sure you are not setting any DISPLAY variables in your startup scripts, and have xAuth installed. You can use ssh -vvv to debug the connection process.
Thanks so much.
Below is what I got error message
[oracle@test01 ~]$ startx
-bash: startx: command not found

There is no need or reason to start or even install the X Window system on your remote Linux server for what you are trying to accomplish. The X Window server only needs to run on the computer that is directly attached to your display and keyboard. In your case that is done with MobaXterm.
With ssh and X forwarding, the X app is running on the remote Linux system, but the X Window output is directed to “localhost”, which the ssh server on your remote system intercepts and tunnels back to the ssh client on on your local PC system, where your X Window server can display the output.
In order to use xclock and ssh with X forwarding make sure you have the following packages installed on your Linux system:
yum install xorg-x11-apps xauth
Then to display a remote X11 app on your PC, like previously outlined, is very simple:
1. Start MobaXterm application
2. type: ssh -X oracle@ip_remote_host
You should then see the remote terminal prompt:
3. type “xclock”
4. It should display an analog clock, or you can see the window icon in the task bar.
