[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。
