oracle-控制檔案備份和恢復

阿新 • • 發佈：2019-02-02

控制檔案(control file)是資料庫重要的檔案，一旦其丟失將導致資料庫宕機。控制檔案在資料庫的MOUNT階段被讀取，它記錄著資料庫許多重要的資訊。因此控制檔案的日常檢查以及一些常規故障恢復方法就是需要我們必須要掌握的。

一、控制檔案的查詢

-->通過引數查詢
[email protected]>show parameter control_files;

NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
control_files                        string      /oracle/ora10g/oradata/control
                                                 01.ctl

 
[email protected]>col name format a30
[email protected]>col value format a50
[email protected]>select name,value from v$parameter where name='control_files';

NAME                           VALUE
------------------------------ --------------------------------------------------
control_files                  /oracle/ora10g/oradata/control01.ctl

-->通過v$controlfile檢視查詢

 
[email protected]>col name for a40
[email protected]>select name from v$controlfile;

NAME
----------------------------------------
/oracle/ora10g/oradata/control01.ctl

控制檔案記錄內容查詢，v$controlfile_record_section檢視displays information about the control file record sections。

二、控制檔案的備份方式
1、對控制檔案進行映象。
由於控制檔案的重要性，在資料庫中一般都配置3個控制檔案映象，這些映象放置在不同的物理磁碟上，減少介質損壞的風險。從上面的資訊可以看到，我們的資料庫只有一個控制檔案，這就需要我們進行控制檔案的映象操作。
-->關閉資料庫
[email protected]>shutdown immediate
Database closed.
Database dismounted.
ORACLE instance shut down.

-->使用主機cp 命令將控制檔案複製到不同路徑。我這裡是簡單的演示，所以都放到了相同路徑下
[email protected][#/home/ora10g]cp /oracle/ora10g/oradata/control01.ctl /oracle/ora10g/oradata/control02.ctl

-->修改control_files引數，將新控制檔案路徑加入
[email protected]>create pfile='/home/ora10g/pfile_20140327.ora' from spfile;

File created.

-->使用vi命令修改control_files引數

2、備份控制檔案到二進位制檔案
[email protected]>alter database backup controlfile to '/home/ora10g/controlfile_20140327.ora';

Database altered.

3、備份控制檔案到trace檔案。這種方式將獲取重建控制檔案的指令碼
[email protected]>alter database backup controlfile to trace;

Database altered.

[email protected]>oradebug setmypid
Statement processed.
[email protected]>oradebug tracefile_name
/oracle/ora10g/admin/testdb/udump/testdb_ora_19847.trc

-->從trace檔案中，我們可以獲取重建controlfile指令碼，例如
STARTUP NOMOUNT
CREATE CONTROLFILE REUSE DATABASE "TESTDB" NORESETLOGS  ARCHIVELOG
    MAXLOGFILES 5
    MAXLOGMEMBERS 5
    MAXDATAFILES 100
    MAXINSTANCES 1

LOGFILE
  GROUP 1 '/oracle/ora10g/oradata/redo01.log'  SIZE 100M,
  GROUP 2 '/oracle/ora10g/oradata/redo02.log'  SIZE 100M,
  GROUP 3 '/oracle/ora10g/oradata/redo03.log'  SIZE 100M
-- STANDBY LOGFILE
DATAFILE
  '/oracle/ora10g/oradata/system01.dbf',
  '/oracle/ora10g/oradata/undotbs01.dbf',

  '/oracle/ora10g/oradata/users01.dbf',
  '/oracle/ora10g/oradata/system02.dbf'
CHARACTER SET US7ASCII
;

4、使用rman備份控制檔案
-->在rman中我們可以設定controlfile的自動備份
CONFIGURE CONTROLFILE AUTOBACKUP ON;
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '/ora_data/wangche/controlfile_%F';
-->在進行全備時，controlfile將一同備份。
RMAN> backup database format '/ora_data/backup/database_full_%U';

Starting backup at 28-MAR-14
using channel ORA_DISK_1
channel ORA_DISK_1: starting full datafile backupset
channel ORA_DISK_1: specifying datafile(s) in backupset
input datafile fno=00004 name=/oracle/ora10g/oradata/users01.dbf

channel ORA_DISK_1: backup set complete, elapsed time: 00:00:35
Finished backup at 28-MAR-14
-->controlfile被自動備份

-->使用rman命令來備份controlfile
RMAN> backup current controlfile format '/ora_data/backup/controlfile_%U';

Starting backup at 28-MAR-14
using channel ORA_DISK_1

channel ORA_DISK_1: backup set complete, elapsed time: 00:00:02
Finished backup at 28-MAR-14
-->這裡由於沒有關閉controlfile的自動備份，所以controlfile被備份了2次

三、不同情況下控制檔案的恢復方式
實踐證明，主機異常掉電導致控制檔案損壞的概率極高，所以系統中至少要儲存兩份控制檔案，以防止單點故障。由於控制檔案中儲存了太多資訊，所以因控制檔案問題而導致資料庫不能啟動的故障很多，DBA應該熟練掌握重建控制檔案的流程。

1、控制檔案映象丟失處理

-->模擬資料庫宕機
[email protected]>shutdown abort
ORACLE instance shut down.
-->手工刪除controlfile檔案，模擬控制檔案丟失
[email protected][#/home/ora10g]cd /oracle/ora10g/oradata
[email protected][#/oracle/ora10g/oradata]ls
control01.ctl  redo01.log     redo03.log     system01.dbf   temp01.dbf     users01.dbf
control02.ctl  redo02.log     sysaux01.dbf   system02.dbf   undotbs01.dbf
