RMAN備份、恢復實驗室 之 備份篇 【歸檔模式】

  
歸檔模式的設定：

如果沒有設定歸檔模式，會出現如下情況：

RMAN> backup database;

Starting backup at 02-AUG-13

using target database control file instead of recovery catalog

allocated channel: ORA_DISK_1

channel ORA_DISK_1: SID=9 device type=DISK

channel ORA_DISK_1: starting full datafile backup set

channel ORA_DISK_1: specifying datafile(s) in backup set

RMAN-03009: failure of backup command on ORA_DISK_1 channel at 08/02/2013 01:45:49

ORA-19602: cannot backup or copy active file in NOARCHIVELOG mode             -------看到了沒？直接不讓你搞啊... ...

continuing other job steps, job failed will not be re-run

channel ORA_DISK_1: starting full datafile backup set

channel ORA_DISK_1: specifying datafile(s) in backup set

including current control file in backup set

including current SPFILE in backup set

channel ORA_DISK_1: starting piece 1 at 02-AUG-13

channel ORA_DISK_1: finished piece 1 at 02-AUG-13

channel ORA_DISK_1: backup set complete, elapsed time: 00:00:01

RMAN-03009: failure of backup command on ORA_DISK_1 channel at 08/02/2013 01:45:49

ORA-19602: cannot backup or copy active file in NOARCHIVELOG mode

 

 

開啟歸檔模式（單節點）：

RMAN> shutdown immediate;

 

database closed

database dismounted

Oracle instance shut down

 

RMAN> startup mount;

 

connected to target database (not started)

Oracle instance started

database mounted

Variable Size                486542352 bytes

Database Buffers             234881024 bytes

Redo Buffers                   7073792 bytes

 

歸檔模式開啟方法：

在RMAN命令符下執行開啟歸檔命令，在sqlplus下直接輸入“alter database archivelog;”回車即可。

RMAN> sql 'alter database archivelog';

 

sql statement: alter database archivelog               --------------歸檔已開啟，當然，你也可以在sqlplus下執行alter database archivelog命令，那樣的話執行結果返回提示更直觀一些，自己動手體驗                                                                                       一把吧，多做比多看更有效果。



歸檔模式已開啟，我們再來備份一下，看看效果如何？

RMAN> backup database;

及時你第一次看著返回結果，很多東西看不明白，但這幾個字眼一目瞭然，告訴我們，資料庫全庫備份成功！~~~   


備份成功了，備份了那些，備份的情況如何怎麼檢視並確認呢？
