在基于Virtual BOX的Oracle Linux上布署11G RAC，执行grid Infrastructure 集群件安装的时候，OUI界面显示不全，右下角缺少"next"与"cancel"按钮，显示如下
点击"System"-->"Administrator"-->"Display"，将分辨率由640x480调整至800x600，然后logout重新登陆，问题依旧。
编辑/etc/X11/xorg.cnf文件，设置分辨率参数Modes，显示如下
div "InputDevice" Identifier "Keyboard[0]" Driver "kbd" Option "XkbModel" "pc105" Option "XkbLayout" "us" Option "Protocol" "Standard" Option "CoreKeyboard"Enddivdiv "InputDevice" Driver "mouse" Identifier "Mouse[1]" Option "Buttons" "9" Option "Device" "/dev/input/mice" Option "Name" "VirtualBox Mouse Buttons" Option "Protocol" "explorerps/2" Option "Vendor" "Oracle Corporation" Option "ZAxisMapping" "4 5" Option "CorePointer"Enddivdiv "InputDevice" Driver "vboxmouse" Identifier "Mouse[2]" Option "Device" "/dev/vboxguest" Option "Name" "VirtualBox Mouse" Option "Vendor" "Oracle Corporation" Option "SendCoreEvents"Enddivdiv "ServerLayout" Identifier "Layout[all]" InputDevice "Keyboard[0]" "CoreKeyboard" InputDevice "Mouse[1]" "CorePointer" InputDevice "Mouse[2]" "SendCoreEvents" Option "Clone" "off" Option "Xinerama" "off" Screen "Screen[0]"Enddivdiv "Monitor" Identifier "Monitor[0]" ModelName "VirtualBox Virtual Output" VendorName "Oracle Corporation"Enddivdiv "Device" BoardName "VirtualBox Graphics" Driver "vboxvideo" Identifier "Device[0]" VendorName "Oracle Corporation"Enddivdiv "Screen" Subdiv "Display" Depth 24

然后重启系统，问题依旧，并且点击"System"-->"Administrator"-->"Display"，发现可选分辨率还是只有640x480和800x600。
百度了一下，网上说要安装Virtual Box增强功能，具体操作如下
点击“安装增强功能”后，桌面会出现VBOXADDITIONS _4.3.10_93012光盘图标，点击图标后，找到“VBOXLinuxAdditions.run”文件
双击运行，屏幕输出以下信息
Verifying archive integrity...

备注：如果双击“VBOXLinuxAdditions.run”文件，屏幕没有输出上面的信息，可以在命令行下进去文件所在路径，以root用户执行。
