-----------------------按文档要求以root用户执行以下命令还是不行

[root@rusky-oracle11g ~]# xhost rusky-oracle11g.com

xhost:  unable to open display "rusky-oracle11g.com:0.0"

[root@rusky-oracle11g ~]# xhost +

xhost:  unable to open display "rusky-oracle11g.com:0.0"

[root@rusky-oracle11g ~]# 



[oracle@rusky-oracle11g ~]# $DISPLAY=192.168.1.203:0.0;export DISPLAY  //以oracle用户执行

最终解决办法：logout,以oracle用户登录图形界面，测试执行xclock弹出图形界面时钟。执行./runinstaller安装oracle正常。

To verify that X applications display is set properly, run a X11 based program that comes with the operating system such as xclock:

$ xclock    //正常情况下，切换到oracle用户执行xclock命令会弹出一个图形界面的时钟。

[oracle@rusky-oracle11g database]$ ./runInstaller
