在原主的基礎上補充一點：
保證目標端的實例名和dbid要一致，密碼文件放置到新庫環境中
創建和源庫相同的控制文件，歸檔文件目錄，還有audit文件的存在路徑，並更改權限
******
注意事項：
1 此處實驗環境爲同平臺，同字節序，同版本，源機器和目標機器相同的目錄結構。
2 目標機器只需要安裝oracle數據庫軟件即可。
3 第一次利用備份恢復測試環境，之後從源機器拷貝備份到目標機器並在控制文件中註冊，再見行恢復測試。
一 拷貝參數文件備份、控制文件備份、數據文件備份、以及歸檔備份到新主機上
1 rman 連接到源數據庫
[oracle@oracle dbs]$ rman target /
Recovery Manager: Release 10.2.0.1.0 - Production on Tue Dec 11 19:02:05 2012
Copyright (c) 1982, 2005, Oracle. All rights reserved.
connected to target database: CRM (DBID=3601019238)
RMAN>
2 分別列出參數文件備份，控制文件備份，數據文件備份，以及歸檔備份的名字
參數文件備份如下：
RMAN> list backup of spfile;

9 Full 2779528081 09-DEC-12 /oracle/test/zxbig.dbf
列出歸檔備份如下：
RMAN> list backup of archivelog all;
注意：歸檔的備份應該包括當前聯機日誌文件。
3 copy 這些備份到新的主機
二 恢復參數文件及控制文件
1 配置新主機上的ORACLE_SID
export ORACLE_SID=CRM
2 在新主機上發起rman連接
[oracle@oracle dbs]$ rman target /
Recovery Manager: Release 10.2.0.1.0 - Production on Mon Dec 10 05:49:11 2012
Copyright (c) 1982, 2005, Oracle. All rights reserved.
connected to target database (not started)
3 設置dbid 並啓動實例到nomount狀態
RMAN> set dbid 3601019238
executing command: SET DBID
RMAN> startup nomount
startup failed: ORA-01078: failure in processing system parameters
LRM-00109: could not open parameter file '/oracle/app/db1/dbs/initCRM.ora'
starting Oracle instance without parameter file for retrival of spfile
Oracle instance started
Total System Global Area 159383552 bytes
Fixed Size 2019224 bytes
Variable Size 67108968 bytes
Database Buffers 83886080 bytes
Redo Buffers 6369280 bytes
注意：在rman下即使沒有參數文件，默認也會啓動一個DUMMY實例，以便能夠恢復參數文件。
4 恢復spfile文件
RMAN> restore spfile to '/oracle/app/db1/dbs/spfileCRM.ora' from '/oracle/app/db1/dbs/0dnsd96i_1_1';
Starting restore at 10-DEC-12
using target database control file instead of recovery catalog
allocated channel: ORA_DISK_1
channel ORA_DISK_1: sid=34 devtype=DISK
channel ORA_DISK_1: autobackup found: /oracle/app/db1/dbs/0dnsd96i_1_1
channel ORA_DISK_1: SPFILE restore from autobackup complete
Finished restore at 10-DEC-12
5 startup force nomount
RMAN> startup force nomount;
Oracle instance started
Total System Global Area 322961408 bytes
Fixed Size 2020480 bytes
Variable Size 96471936 bytes
Database Buffers 218103808 bytes
Redo Buffers 6365184 bytes
6 恢復控制文件
RMAN> restore controlfile to '/oracle/CRM2/CRM/control01.ctl' from '/oracle/app/db1/dbs/0dnsd96i_1_1';
Starting restore at 10-DEC-12
allocated channel: ORA_DISK_1
channel ORA_DISK_1: sid=210 devtype=DISK
channel ORA_DISK_1: restoring control file
channel ORA_DISK_1: restore complete, elapsed time: 00:00:04
Finished restore at 10-DEC-12
cp /oracle/CRM2/CRM/control01.ctl /oracle/CRM2/CRM/control02.ctl
7 啓動數據庫到加載狀態
RMAN> alter database mount;
database mounted
released channel: ORA_DISK_1
三 在新控制文件中註冊數據文件備份和歸檔備份
RMAN> catalog start with '/backup/';
searching for all files that match the pattern /backup/
List of Files Unknown to the Database
=====================================
File Name: /backup/0ensd96n_1_1
File Name: /backup/0bnsd8vn_1_1
File Name: /backup/0cnsd8vq_1_1
Do you really want to catalog the above files (enter YES or NO)? yes
cataloging files...
cataloging done
List of Cataloged Files
=======================
File Name: /backup/0ensd96n_1_1
File Name: /backup/0bnsd8vn_1_1
File Name: /backup/0cnsd8vq_1_1
四 恢復整個庫
1 RMAN> restore database;
Starting restore at 10-DEC-12
allocated channel: ORA_DISK_1
channel ORA_DISK_1: sid=209 devtype=DISK
channel ORA_DISK_1: starting datafile backupset restore
channel ORA_DISK_1: specifying datafile(s) to restore from backup set
restoring datafile 00001 to /oracle/test/system1.dbf
restoring datafile 00002 to /oracle/test/zxb.dbf
restoring datafile 00003 to /oracle/test/sysaux01.dbf
restoring datafile 00004 to /oracle/test/users01.dbf
restoring datafile 00005 to /oracle/test/zxa.dbf
restoring datafile 00006 to /oracle/test/test1.dbf
restoring datafile 00007 to /oracle/test/zxc.dbf
restoring datafile 00008 to /oracle/test/undotbs1.dbf
restoring datafile 00009 to /oracle/test/zxbig.dbf
channel ORA_DISK_1: reading from backup piece /oracle/app/db1/dbs/0cnsd8vq_1_1
channel ORA_DISK_1: restored backup piece 1
piece handle=/oracle/app/db1/dbs/0cnsd8vq_1_1 tag=TAG20121209T040058
channel ORA_DISK_1: restore complete, elapsed time: 00:02:56
Finished restore at 10-DEC-12
2 RMAN> recover database;
Starting recover at 10-DEC-12
using channel ORA_DISK_1
starting media recovery
archive log thread 1 sequence 16 is already on disk as file /oracle/CRM2/CRM/redo04b.log
archive log thread 1 sequence 17 is already on disk as file /oracle/CRM2/CRM/redo05.log
archive log filename=/oracle/CRM2/CRM/redo04b.log thread=1 sequence=16
archive log filename=/oracle/CRM2/CRM/redo05.log thread=1 sequence=17
media recovery complete, elapsed time: 00:00:05
Finished recover at 10-DEC-12
3 alter database open resetlogs 打開數據庫
SQL> alter database open resetlogs；
Database altered.
總結：到此，庫已經恢復完成，以後只需要把源機器數據備份、歸檔備份，或者歸檔文件，拷貝到目標機器上，並在控制文件中註冊該備份(catalog start with ‘/backup/’)然後執行恢復即可。
