os及相关安装前环境搞定后，运行runinstaller，报错如下：

   很明显，是libXp包没有装全，马上加载光盘介质，先装下libXp for x86-64bit  rpm包，还是出错，所幸把libXp for i386包装上，再次运行runinstaller,ok.图形界面弹出来了

小感：

    oracle官方手册作得不具体，只是说要装libxp包，没有细化到具体版本,比如如果是64bit os，按理应装上64bit rpm包就可以了，为何还要装上32bit rpm包才行。

    64 or 32 bit os与oracle 32 or 64 bit包的对应兼容关系，有空要理下，太重要

   自己一直到于32bit or 64bit的概念理解不清晰，到底是针对cpu呢，还是什么东东
