[2]检测通过后修改response file
/**
* To use noninteractive mode, you run Oracle Universal Installer with a response file. A response file is a text file that contains variables and values that Oracle Universal Installer uses during the installation process
*/
在安装软件install\response目录下有如下文件：custom.rsp， dbca.rsp，emca.rsp，enterprise.rsp，netca.rsp，standard.rsp
选择enterprise.rsp修改参数
注：怎么自定义response file
ex:
./runInstaller -record -destinationFile C:\response_files\install_oracle10g.rsp
弹出用户图形界面  选择选项后 操作被记录到install_oracle10g.rsp中
[3]安装
 ./runInstaller -silent -responseFile ../database/response/enterprise.rsp

其他rsp的应用
cat dbca.rsp
[oracle@rac1 response]$ less dbca.rsp
