Linux 平台 Oracle 安装 报错 Check if the DISPLAY variable is set 解决方法

在Oracle Linux 6.1 上安装Oracle 11.2.0.3， 在运行runInstaller 时报错。 具体如下：


[root@dave mnt]# xhost +


access control disabled, clients canconnect from any host


[root@dave mnt]# su - oracle


[oracle@dave ~]$ cd /u01/software/database/


[oracle@dave database]$ ls


doc     readme.html  rpm           sshsetup  welcome.html


install response     runInstaller  stage


[oracle@dave database]$ export DISPLAY=127.0.0.1:0.0


[oracle@dave database]$ ./runInstaller

[oracle@dave database]$


解决方法：


在OS中注销用户并切换到oracle 用户，就可以执行了，如下：


[oracle@dave database]$ ./runInstaller


Starting Oracle Universal Installer...


Checking Temp space: must be greater than120 MB.   Actual 9048 MB    Passed


Checking swap space: must be greater than150 MB.   Actual 1999 MB    Passed


Checking monitor: must be configured todisplay at least 256 colors.    Actual16777216    Passed


Preparing to launch Oracle UniversalInstaller from /tmp/OraInstall2012-04-13_09-24-13PM. Please wait ...


应该还有其他的解决方法，这里不在研究原因了。
