On Windows, at-least, once in a while DBAs need to remotely access the UNIX/Linux GUI tools such as OUI, DBCA etc from putty or an SSH client. Tools like Exceed are very expensive and VNC port forwarding is a bit of complex solution (also you need vnc software).
To overcome this, you can try this tiny little software called Xming. The setup file is only about 2MB of size and very easy to install. All you need to do is to start the Xming, open a putty session and check “Enable X11 Forwarding” option under SSH->X11. Log into the Linux/Unix sever and straight away you can test it by running xlogo/xclock. No need to even set the DISPLAY env variable. Very nice indeed.
I just tried it and it is absolutely working fine 🙂 .
