如果你需要安装的数据库服务器比较多，使用图形化方式安装数据库软件的速度还是很慢，而且也比较麻烦。Oracle 11g 提供了Clone安装的方法。
步骤如下：
使用正常方法在服务器A上安装好Oracle。
将A机器上的$ORACLE_HOME打包，db_home1.zip 。
将B机器的环境准备好，如建立用户、建立用户、修改内核参数，修改环境变量等等。
将zip包copy到B服务器，解压到任意目录。
执行Clone命令
1.A机器上打包
[root@localhost oracle]# zip -r db_1.zip /u01/app/oracle/product/11.2.0/db_1/
2. 准备B机器环境
[root@localhost inst_env_scripts]# ./1preusers.sh
[root@localhost inst_env_scripts]# ./2predir.sh
[root@localhost inst_env_scripts]# ./3prelimits.sh
[root@localhost inst_env_scripts]# ./4presysctl.sh
脚本内容如下
[root@localhost inst_env_scripts]# cat 1preusers.sh
#!/bin/bash
#Purpose:Create 3 groups named 'oinstall','dba','oper', plus 1 users named 'oracle'.
#Also setting the Environment
#variable for oracle user.
#variable for grid user.
#Usage:Log on as the superuser('root'),and then execute the command:#./1preusers.sh

echo "Plus 1 users named 'oracle',Also setting the Environment"

3. 将A机器上的zip包copy到B机器上
[root@localhost inst_env_scripts]# scp 192.168.199.163:/home/oracle/db_1.zip /home/oracle/
