Oracle数据库的安装过程
一、准备安装
基本都是按部就班。
使用的OS版本：OEL4 [oracle@ractestorcl]$cat/etc/redhat-releaseEnterpriseLinuxEnterpriseLinuxASrelease4(OctoberUpdate5)[oracle@ractestorcl]$cat/etc/enterprise-releaseEnterpriseLinuxEnterpriseLinuxASrelease4(OctoberUpdate5)安装程序路径：

使用xclock检查display正确：

启动图形以后选择basic&n
选择oracle base的时候，oracle不推荐使用user home作为oracle base，这里我选yes忽略
进行prerequirements检查的时候，安装程序认为swap不足，我选择YES忽略
执行提示脚本，安装完毕
