Checking monitor: must be configured to display at least 256 colors >>> Could not execute auto check for display colors using command /usr/openwin/bin/xdpyinfo. Check if the DISPLAY variable is set. Failed <<<<

解决 要点主要是要运行host +打通 接受控制；不是去安装啥补丁！安装啥包

如果碰到以上这个问题，就跟着下面的设置一定可以搞定！如果还是不能拿就是RP问题了。。。

1．先进入ROOT内：

su – root

password:xxxxx

DISPLAY=:0.0; export DISPLAY

echo $DISPLAY

cd /usr/openwin/bin

./xhost

access control enabled, only authorized clients can connect

./xhost +

access control disabled, clients can connect from any host

2. 然后进入ORACLE

su - oracle

$ DISPLAY=:0.0; export DISPLAY

$ echo $DISPLAY

:0.0

$ ls

 doc           response      stage

 install       runInstaller  welcome.html

$ ./runInstaller
