系统要求：
　　内存：推荐1G
　　Swap分区：设为内存的2倍
　　/tmp磁盘空间：400MB以上三
　　磁盘空间：软件3.5G 数据1.2G
　　所需软件：
　　SuSE Linux10 for x86
　　Oracle database 10gR2 for Linux32
　　Orarun-1.8-109.15.i586.rpm软件包，可以从http://Ftp.novell.com/partners/Oracle/sels-9下载
（由于suse linux 10己经oracle认证，所以orarun rpm包和安装数据库所用到的组己经和系统默认安装给用户了，当然是你选择这个才有的 add by warden2010)
　　安装步骤：
　　1、安装SuSE
　　安装SuSE一定确保安装“C/C++Compiler and Tools”软件包。
　　# gcc –version 查看是否安装该软件包
　　2、安装所需软件包
　　安装orarun软件包
　　#rpm –ivh orarun-1.8-109.15.i586.rpm
　　安装libaio和libaio-devel软件包，这两个软件包可以在SuSE Linux DISK4中找到
　　#rpm –ivh orarun-1.8-109.15.i586.rpm
　　#rpm –ivh libaio-devel-0.3.104-3.i586.rpm
3、Oracle用户设置
　　当orarun软件包安装时，会自动建立名为Oracle的用户，和一个oinstall组。我们只需要� ......
