这里我们看一下在Oracle Linux 下Oracle 的安装。
2.1 安装软件下载
Oracle从11g开始安装介质就可以独立进行安装，，从OTN上我们只能下载到11.2.0.1版本，从MOS上，我们可以下载到11.2.0.3版本。 我这里使用MOS上的11.2.0.3版本进行测试。
OTN上的下载地址：
Oracle 11g的Patchset 分几个文件，每个文件的作用都不同。
第一， 二个包表示database , 如果升级数据库，只需要这2个文件即可。
第三个包表示grid, 用来升级RAC 的CRS。如果升级RAC 要先用这个文件。
第四个表示客户端，
第五个表示gateways,
第六个表示examples, 这个是我们的示例文件安装包。
第七个表示deinstall .
