oracle異構rman遷移

目前rman支持的異構恢復、還原和複製版本及對應的平臺如下：

For Oracle Database 10g Release 2 and above releases:  
Solaris x86-64   <-->  Linux x86-64  
HP-PA   <-->  HP-IA  
Windows IA (64-bit) / Windows (64-bit Itanium) <--> Windows 64-bit for AMD / Windows  (x86-64)  
 
For Oracle Database 11g Release 1 and above releases (requires minimum 11.1 compatible  setting):  
Linux  <-->  Windows  
 
For Oracle Database 11g Release 2 (11.2.0.2) and above releases:  
Solaris SPARC (64-bit) <-->  AIX (64-bit) - Note: this platform combination is currently not supported due to Bug 12702521

以下oracle 11.2.0.3的windows到linux爲例：

1. 在windows上利用rman備份數據庫

RMAN> run{
2> backup database format 'E:\bk_%d_%t_%s';
3> backup archivelog all format 'E:\al_%d_%t_%s';
4> backup current controlfile format 'E:\cntrl_%d_%t_%s';
5> }

2. 在linux 服務器上任意創建一個目錄(如：/home/oracle/backup)，將備份集ftp 到該目錄下

3. 恢復spfile

#su – oracle 
$export ORACLE_SID=orcl 
$rman target / nocatalog

4.修改所有關於windows下目錄的參數如下：

orcl.__db_cache_size=138412032 
orcl.__java_pool_size=4194304 
orcl.__large_pool_size=4194304 
#orcl.__oracle_base='E:\app\Administrator'#ORACLE_BASE set from environment 
orcl.__oracle_base='/oracle/product' 
orcl.__pga_aggregate_target=176160768 
orcl.__sga_target=255852544 
orcl.__shared_io_pool_size=0 
orcl.__shared_pool_size=100663296 
orcl.__streams_pool_size=0 
#*.audit_file_dest='E:\app\Administrator\admin\orcl\adump' 
*.audit_file_dest='/oracle/product/admin/orcl/adump' 
*.audit_trail='db' 
*.compatible='11.2.0.0.0' 
#*.control_files='E:\oradata\orcl\control01.ctl','E:\oradata\orcl\control02.ctl' 
*.control_files='/oradata/orcl/control01.ctl','/oradata/orcl/control02.ctl' 
*.db_domain='' 
*.db_name='orcl' 
#*.diagnostic_dest='E:\app\Administrator' 
*.diagnostic_dest='/oracle/product' 
*.nls_language='SIMPLIFIED CHINESE' 
*.nls_territory='CHINA' 
*.open_cursors=300 
*.processes=150 
*.remote_login_passwordfile='EXCLUSIVE' 
*.undo_tablespace='UNDOTBS1

手工創建相關目錄:

$mkdir -p /oracle/product/admin/orcl/adump
$mkdir –p /oradata/orcl

5.恢復控制文件

SQL> create spfile from pfile;
File created.
 
$rman target / nocatalog

RMAN> restore controlfile from '/home/oracle/backup/CNTRL_ORCL_790791465_5';
 
Starting restore at 2012-08-08 22:30:49
allocated channel: ORA_DISK_1
channel ORA_DISK_1: SID=19 device type=DISK
channel ORA_DISK_1: restoring control file
channel ORA_DISK_1: restore complete, elapsed time: 00:00:04
output file name=/oradata/orcl/control01.ctl

Finished restore at 2012-08-08 22:30:53
 
RMAN> alter database mount;
database mounted
released channel: ORA_DISK_1

6.將備份集信息導入控制文件：

 
RMAN> catalog start with '/home/oracle/backup/'; 
 
searching for all files that match the pattern /home/oracle/backup/ 
List of Files Unknown to the Database 
===================================== 
File Name: /home/oracle/backup/BK_ORCL_790791123_3 
File Name: /home/oracle/backup/BK_ORCL_790791088_2 
File Name: /home/oracle/backup/AL_ORCL_790791226_4 
File Name: /home/oracle/backup/CTL_ORCL_790791465_5 
 
Do you really want to catalog the above files (enter YES or NO)? Y 
cataloging files... 
cataloging done 
 
List of Cataloged Files 
======================= 
File Name: /home/oracle/backup/BK_ORCL_790791123_3 
File Name: /home/oracle/backup/BK_ORCL_790791088_2 
File Name: /home/oracle/backup/AL_ORCL_790791226_4 
File Name: /home/oracle/backup/CTL_ORCL_790791465_5

7.恢復數據文件：

RMAN> run{    
2> set newname for datafile 1 to '/oradata/orcl/SYSTEM01.DBF'; 
3> set newname for datafile 2 to '/oradata/orcl/SYSAUX01.DBF'; 
4> set newname for datafile 3 to '/oradata/orcl/UNDOTBS01.DBF'; 
5> set newname for datafile 4 to '/oradata/orcl/USERS01.DBF'; 
6> restore database; 
7> switch datafile all; 
8> recover database; 
9> }

以resetlogs方式打開數據庫：
SQL> alter database open resetlogs;

注意由於redo log和tempfile的路徑都還是以windows目錄方式記錄在控制文件中，需要對其進行修改

QL> select member from v$logfile;

做下日誌切換：

由於是windows目錄格式linux 下oracle無法識別文件路徑，無法使用tempfile drop方式刪除文件;可以通過在線重建temp 表空間方式更改，這裏使用重建控制文件方式更改：

SQL> alter database backup controlfile to trace as '/oracle/control.trc'; 
SQL> shutdown immediate

Database dismounted. 
ORACLE instance shut down. 
SQL> startup nomount
