3、7 配置脚本执行用法

因脚本化，需要考虑的问题还有很多，所以还有很多细节需要调整，脚本目前只给出的框架，有兴趣的童鞋，欢迎一起研究，或者有好的方法一起改写。

四、克隆安装ORACLE软件实现补丁一同安装
4、1 克隆安装ORACLE的可行性
通过上面的安装过程，细心的你一定发现，只是安装了oracle软件，而相应要打的PSU并没有打上，有没办法安装和打补丁一起呢？有，那就是克隆。为了保证克隆安装后，不出现问题，首先要保证tar包的准确性，这种安装方式用于生产环境是有一定风险的，但对于开发环境和测试环境，我觉得是可行的。
4、2 克隆安装ORACLE的大概步骤
?系统环境准备，ip、/etc/hosts等这些配置，之后再执行其它环境配置的脚本
?克隆安装oracle软件shell主体（install_oracle_main.sh）
?系统配置及tar安装介质下载（install_configure.sh）
?RPM包安装及配置（install_rpm.sh）
?软件安装用户建立及用户环境配置（create_user.sh）
?RAC安装的SSH等效配置（ssh_setup.sh）
?进行克隆安装，这里考虑的地方还是蛮多的，难点也在于ASM的克隆，若是RAC，OCR的注册这些。用户的uid、gid是否一致，需要安装的oracle home目录是否一致等。
五、延伸扩展（定制ORACLE安装的ISO镜像文件）
熟悉操作系统安装和ORACLE的童鞋都知道，我们在Linux环境安装ORACLE的时候都知道，很多服务都是用 不到的，比如bluetooth蓝牙、cups打印服务这些都是不需要的，像这类服务如果在安装操作系统的时候多安装了，并开启了肯定是会占用一定的资源的。这里有个构想，使用UltraISO直接制作安装ORACLE的ISO镜像，去除不必要服务RPM包，将oracle安装包”database”加入到ISO镜像中，直接在安装操作系统的同时，一同安装数据库。有兴趣的童鞋可以研究一下。
