Use the following command to see what shell is being used:
        echo $SHELL
Use the following command to view the current DISPLAY environment variable setting:
        echo $DISPLAY

If you are not able to run xclock successfully, please refer to your PC-X Server or OS vendor for further assistance.
Typical path for xclock: /usr/bin/X11/xclock

使用VNC连接到远程服务器上安装oracle。这个DISPLAY应该如何设置呢？
