合 Duplicating a Database Without Recovery Catalog or Target Connection
duplicate体系结构
搞点英语出来吧，英语不好的哥们就好好翻译翻译吧，这段英语是必须看懂的。。。。
You can duplicate a source database to a destination database, which can be on the same or different computers. The database instance associated with the duplicate database is called the auxiliary instance. All duplication techniques require a connection to the auxiliary instance. The diagram shows you the following techniques for database duplication:
- From an active database, connected to the target and auxiliary instances
- From backup, connected to the target and auxiliary instances
- From backup, connected to the auxiliary instance, not connected to the target, but with recovery catalog connection
- From backup, connected to the auxiliary instance, not connected to the target and the recovery catalog
Choosing a technique to duplicate your database—always with connection to the auxiliary instance:
简单点就是 ①基于备份 ，而基于备份又分为3种情况 ②基于活动数据库
本次实验简介
本次实验就是基于备份，但是不连接到目标数据库，也不连接到恢复目录。
When you duplicate a database without a target database connection and without a recovery catalog, RMAN uses a BACKUP LOCATION where all necessary backups and copies reside.
The diagram illustrates backup-based duplication without connections to the target or to the recovery catalog database instance. A disk backup location containing all the backups or copies for duplication must be available to the destination host.
本次实验原理图
环境及搭建要求
环境：
- Destination host ：192.168.59.133 sid：orcl database：11gR2
注意事项说明：
- 这里的duplicate database 和 source database 的目录结构完全一样
- 源数据库和辅助数据库的几种不同名称：source/target database ---->>>>>----- (destination host)/duplicate database (auxiliary instance)
source database环境：
SQL> select * from v$version;

对辅助数据库的要求
辅助数据库应该提前安装好数据库，配置好环境变量。。。。。
辅助数据库的环境变量配置：
[root@rhel6 ~]# su - oracle
[oracle@rhel6 ~]$ more .bash_profile
# .bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
