Duplicating a Database Without Recovery Catalog or Target Connection

Duplicating a Database Without Recovery Catalog or Target Connection
-
duplicate體系結構
-
搞點英語出來吧，英語不好的哥們就好好翻譯翻譯吧，這段英語是必須看懂的。。。。
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:
簡單點就是 ①基於備份 ，而基於備份又分為3種情況 ②基於活動資料庫
-
本次實驗簡介
本次實驗就是基於備份，但是不連線到目標資料庫，也不連線到恢復目錄。
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.

環境及搭建要求
環境：
-
Destination host ：192.168.59.133 sid：orcl database：11gR2
注意事項說明：
-
這裡的duplicate database 和 source database 的目錄結構完全一樣
-
源資料庫和輔助資料庫的幾種不同名稱：source/target database ---->>>>>----- (destination host)/duplicate database (auxiliary instance)
source database環境：
SQL> select * from v$version;

對輔助資料庫的要求
輔助資料庫應該提前安裝好資料庫，配置好環境變數。。。。。
輔助資料庫的環境變數配置：

# .bash_profile
# Get the aliases and functions

解決辦法：由於fra是直接從目標資料庫copy過來的，可能db_recovery_file_dest_size 設定過小，所以啟動auxiliary庫到nomount狀態，然後把該引數改大一點即可（alter system set db_recovery_file_dest_size=8G;）

duplicate target database to orcl backup location '/u01/app/oracle/flash_recovery_area/ORCL/backupset/2014_07_20' nofilenamecheck;
