注意事项：1此处实验环境为同平台，同字节序，同版本，源机器和目标机器相同的目录结构。2目标机器只需要安装oracle数据库软件即可。3第一次利用备份恢复测试环
注意事项：
1 此处实验环境为同平台，同字节序，美国空间，同版本，源机器和目标机器相同的目录结构。
2 目标机器只需要安装oracle数据库软件即可。
3 第一次利用备份恢复测试环境，香港服务器，之后从源机器拷贝备份到目标机器并在控制文件中注册，再见行恢复测试。
一 拷贝参数文件备份、控制文件备份、数据文件备份、以及归档备份到新主机上
1 rman 连接到源数据库
[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 分别列出参数文件备份，控制文件备份，数据文件备份，以及归档备份的名字
参数文件备份如下：
RMAN> list backup of spfile;

9 Full 2779528081 09-DEC-12 /oracle/test/zxbig.dbf
列出归档备份如下：
RMAN> list backup of archivelog all;
注意：归档的备份应该包括当前联机日志文件。
3 copy 这些备份到新的主机
二 恢复参数文件及控制文件
1 配置新主机上的ORACLE_SID
export ORACLE_SID=CRM
2 在新主机上发起rman连接
[oracle@oracle dbs]$ rman target /

connected to target database (not started)
3 设置dbid 并启动实例到nomount状态
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

Fixed Size 2019224 bytes
Variable Size 67108968 bytes
Database Buffers 83886080 bytes
Redo Buffers 6369280 bytes
注意：在rman下即使没有参数文件，默认也会启动一个DUMMY实例，香港服务器租用，以便能够恢复参数文件。
4 恢复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 恢复控制文件
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 启动数据库到加载状态
RMAN> alter database mount;
database mounted
released channel: ORA_DISK_1
三 在新控制文件中注册数据文件备份和归档备份
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 恢复整个库

Finished restore at 10-DEC-12
2 RMAN> recover database;
Starting recover at 10-DEC-12
using channel ORA_DISK_1
starting media recovery
