vi /etc/oraInst.loc inventory=/oracle/app/oraInventory inst_group=oinstall
chown oracle:oinstall /etc/oraInst.loc （免除1 orainstRoot.sh）
安装命令
./runInstaller -silent -ignoreSysPrereqs -showProgress -responseFile /home/oracle/db_install.rsp
其中-silent指的是静默安装，-ignorePrereq忽略prerequisite的检查结果，showProgress显示进度，responseFile是种子文件
最后，需root用户手动执行以下两个文件：
1. /u01/app/oracle/oraInventory/orainstRoot.sh
2. /u01/app/oracle/product/11.2.0.1/db_1/root.sh
当然，也可查看/u01/app/oracle/oraInventory/logs/installActions2015-04-01_10-13-42PM.log了解具体的安装信息。

遇到的问题
1 db_install模板11g和12c 不同版本必要的参数不一致 导致安装失败
2 dbca模板也是一样不同版本建立不一致导致失败，导致实例出现问题，没有控制文件，启动也启动不起来，解决方法用最小化dbca重新安装重建
3 ORA-00205: error in identifying control file, check alert log for more info 控制文件损坏错误
4 启动数据库时遇到ORA-01102: cannot mount database in EXCLUSIVE mode
a、 Oracle的共享内存段或信号量没有被释放；
b、 Oracle的后台进程（如SMON、PMON、DBWn等）没有被关闭；
c、 用于锁内存的文件lk<sid>和sgadef<sid>.dbf文件没有被删除。 关闭数据库实例，删除/u01/app/oracle/product/10.2.0/db_1/dbs/lkEPPS文件
5 静默安装Oracle11gR2 [FATAL] [INS-32015]报错 模板问题版本不同 [FATAL] [INS-32015] The location specified for Oracle home Location is invalid.
建议
1 如果条件允许，oracle安装尽量使用图形化界面操作，静默安装虽然效率快方便部署，但是出现问题太多不好解决，图形化安装不容易出现问题
