oracle rman異機恢復

	Oracle源主機	Oracle目標主機
主機平臺	CentOS6.2（final）	CentOs6.2（FInal）

控制文件路徑	/u01/app/oracle/oradata	/u01/app/oracle/oradata
數據文件路徑	/u01/app/oracle/oradata	/u01/app/oracle/oradata
在線重作日誌路徑	/u01/app/oracle/oradata	/u01/app/oracle/oradata

查看源庫的控制文件信息：

SQL> select name from v$controlfile;


NAME
------------------------------------------------------------------------------
/u01/app/oracle/oradata/orcl/control01.ctl
/u01/app/oracle/fast_recovery_area/orcl/control02.ctl

源庫的數據文件信息：

SQL> select file#,name from v$datafile;

FILE# NAME

--------------------------------------------------------------------------------

1 /u01/app/oracle/oradata/orcl/system01.dbf

2 /u01/app/oracle/oradata/orcl/sysaux01.dbf

3 /u01/app/oracle/oradata/orcl/undotbs01.dbf

4 /u01/app/oracle/oradata/orcl/users01.dbf

5 /u01/app/oracle/oradata/orcl/tbs_catalog.dbf

6 /u01/app/oracle/oradata/orcl/dave01.dbf

源庫在線重作日誌文件：

SQL> select group#,member from v$logfile;

 GROUP#MEMBER

--------------------------------------------------------------------------------

1 /u01/app/oracle/oradata/orcl/redo01.log

2 /u01/app/oracle/oradata/orcl/redo02.log

3 /u01/app/oracle/oradata/orcl/redo03.log

假設路徑有不一樣的地方則需要進行相關操做

在源數據庫上用rman備份數據庫，包含數據庫

[oracle@vick ~]$ mkdir  /u01/backup

[oracle@vick ~]$ rman target /

RMAN> run {
2> allocate channel c1 device type disk;
3> backup incremental level 0
4> format '/u01/backup/db_full_%U.bkp'
5> tag '2014-11-14-FULL'
6> database plus archivelog;
7> release channel c1;
8> }

RMAN> backup current controlfile format '/u01/backup/control20141114 .bak';

RMAN> backup spfile format '/u01/backup/spfile20141114.bak';

2、在目標主機上覆製備份數據。並準備好相關文件夾

將備份傳到目標主機

[oracle@vick backup]$ scp * 192.168.1.10:/u01/backup

db_full_3kpnjk76_1_1.bkp                                     100%  148MB  11.4MB/s   00:13    
db_full_3lpnjk7l_1_1.bkp                                     100% 1103MB   7.8MB/s   02:22    

control20141114 .bak                                         100% 9664KB   9.4MB/s   00:01    
spfile20141114.bak                                           100%   96KB  96.0KB/s   00:00

建立相關文件夾

[oracle@rman orcl]$ mkdir {adump,bdump,cdump,dpdump,udump,pfile}

[oracle@rman ~]$ mkdir -p /u01/app/oracle/oradata/orcl

[oracle@rman ~]$ mkdir -p /u01/app/oracle/fast_recovery_area/ORCL

建立password文件：

[oracle@rman dbs]$ orapwd file=$ORACLE_HOME/dbs/orapw$ORACLE_SID password=oracle

建立initorcl.ora文件

[oracle@rman ~]$ echo 'db_name=orcl'>$ORACLE_HOME/dbs/initorcl.ora

異機恢復-->下面操做在目標主機運行

設置DBID

查看尋源主機DBID

SQL> select dbid from v$database;

      DBID
----------
1387254920

[oracle@rman dbs]$ rman target /

RMAN> set dbid 1387254920


executing command: SET DBID

MAN> startup nomount;


connected to target database (not started)
Oracle instance started

Database Buffers              50331648 bytes
Redo Buffers                   5189632 bytes

恢復參數文件

RMAN> restore spfile from '/u01/backup/spfile20141114.bak';

Starting restore at 14-NOV-14
allocated channel: ORA_DISK_1
channel ORA_DISK_1: SID=19 device type=DISK

channel ORA_DISK_1: restoring spfile from AUTOBACKUP /u01/backup/spfile20141114.bak
channel ORA_DISK_1: SPFILE restore from AUTOBACKUP complete
Finished restore at 14-NOV-14

從新啓動nomout
RMAN> startup nomount force;
Oracle instance started
Total System Global Area     613797888 bytes

Fixed Size                     2255712 bytes
Variable Size                427820192 bytes
Database Buffers             180355072 bytes
Redo Buffers                   3366912 bytes

恢復控制文件

RMAN> restore controlfile from '/u01/backup/control20141114 .bak';
Starting restore at 14-NOV-14
using channel ORA_DISK_1

channel ORA_DISK_1: restoring control file
channel ORA_DISK_1: restore complete, elapsed time: 00:00:01
output file name=/u01/app/oracle/oradata/orcl/control01.ctl
output file name=/u01/app/oracle/fast_recovery_area/orcl/control02.ctl
Finished restore at 14-NOV-14

RMAN> startup mount

RMAN>restore database；

假設這一步無法運行可以使用list incarnation產看相關信息。切換一下再運行

reset database to incarnation XX；

RMAN> recover database;

RMAN-03002: failure of recover command at 11/14/2014 22:19:36
RMAN-06053: unable to perform media recovery because of missing log
RMAN-06025: no backup of archived log for thread 1 with sequence 13 and starting SCN of 1208284

這一步竟然報錯了。後來我發現沒有運行catalog 

而後我運行了catalog start with ‘/u01/backup/’；

完了再次運行recover

但是仍是出錯現了相同的錯誤

而後我運行list backup of archivelog all查看後，運行了下面腳本就行了

RMAN> run {
2> set until scn 1208284;
3> recover database;
4> }


executing command: SET until clause


Starting recover at 14-NOV-14
using channel ORA_DISK_1
using channel ORA_DISK_2
using channel ORA_DISK_3
using channel ORA_DISK_4


starting media recovery
media recovery complete, elapsed time: 00:00:00


Finished recover at 14-NOV-14

而後登錄數據庫運行

SQL> alter database open resetlogs;
alter database open resetlogs
*
ERROR at line 1:
ORA-19751: could not create the change tracking file
ORA-19750: change tracking file:
'/u01/app/oracle/oradata/orcl/ORCL/changetracking/o1_mf_b51rj77x_.chg'
ORA-27040: file create error, unable to create file
Linux-x86_64 Error: 2: No such file or directory
Additional information: 1
ORA-27037: unable to obtain file status
Linux-x86_64 Error: 2: No such file or directory
Additional information: 3

又出錯了，我就去/u01/app/oracle/oradata/orcl/ORCL/changetracking/文件夾查看沒有這個文件夾

而後我運行了

SQL>ALTER DATABASE DISABLE BLOCK CHANGE TRACKING;

而後關閉數據庫shutdown immediate。

再運行startup；

數據庫成功啓動

搞這個異機恢復，第一次搞了2天，頭都大了，好多解決方法都沒用。以上爲我的遇到的問題，但願對一些遇到同類問題的朋友有幫助

改變change tracking file的位置 1) 不關閉數據庫的方式 SQL> ALTER DATABASE DISABLE BLOCK CHANGE TRACKING; SQL> ALTER DATABASE ENABLE BLOCK CHANGE TRACKING USING FILE 'new_location'; 注意：這樣的方式會丟失change tracking file的內容
