在redhat6.5上安装Oracle时，最后使用oracle用户执行runInstaller 报错如下,无法连接到安装有xmanager的windows服务器，也就无法图形化安装oracle
oracle@sjb] :./runInstaller Starting Oracle Universal Installer... Checking Temp space: must be greater than 120 MB. Actual 42217 MB Passed Checking swap space: must be greater than 150 MB.

经过百度找到一个靠谱的解决方法，实验成功。如下首先检查服务器是否安装了xdpyinfo
[oracle@sjb] :/usr/bin/xdpyinfo
-bash: /usr/bin/xdpyinfo: No such file or directory ---发现并没有安装xdpyinfo
切换到root用户，安装xdpyinfo，需要安装的包很多，可见配置yum源的重要性。
