no we have to prepare a test POC but we don't have Xterm so had to use silent mode.
using VNC server is best option to install or upgrade databases/grid Infrastructure.
VNC server runs on the server and no fear of loosing network connection as in case of connecting thorugh putty.
also you can open GUI in VNC server without need of any xterm or xwindows .
So ask your SA to install VNC on your server and use it.
Agreed. VNC is great. I also use a VNC server when I need to execute very long-running operations. You can even have multiple people connect via vncviewer (click options - select SHARED (or something to that effect) when connecting. This can be useful if you want to do training or have another set of eyes on a problem without looking over their shoulder. You can even close vncviewer, go home and reconnect to that long running process.
