Linux 平台 Oracle 安装 报错 Check if the DISPLAY variable is

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。
