Oracle 备份与恢复学习笔记(5_1)

第五章:手工完全恢复(归档模式)

1、完全恢复;通过备份、归档日志、current redo ,将database恢复到failure 前的最后一次commit 状态。

media  recover的原因?
----------由于media  failure 导致数据文件或controlfile 丢失

media recover的分类?
  ------------归档模式     
       1)完全恢复
       2)不完全恢复
--------------非归档模式
      1)恢复到最后一次备份

2、instance recover 和 media  recover 区别:
 -------instance recover :instance 没有正常关闭 ,由smon 执行
 -------media recover:因为介质failure,文件丢失,需dba 通过备份和redo 来恢复

3、media recover的步骤:
         1、restore 转储:将备份恢复到丢失文件的原位置
         2、recover  恢复: 利用redo 日志,将备份点后的数据块通过redo 日志进行重做

4、如何restore 和 recover

          1)restore:手工恢复用的是os 下的拷贝命令。如cp 
          2)recover: sql 命令

5、非归档模式下的数据恢复
      1)转储所有的datafile 和controlfile
      2)如果日志以切换,历史日志被覆盖,只能恢复到最近备份;如果日志没有发生切换,可以恢复到最后commit 状态
     

6、归档模式下的数据恢复
     1)完全恢复
     2)不完全恢复

7、完全恢复和不完全恢复的区别
     1)完全恢复:需要所有的备份和redo 日志,可以将datafile恢复到failure前得最后一次commit,不会出现数据丢失
     2)不完全恢复:通过备份和日志将database恢复到过去的某个时间点,有数据丢失。(尽量避免)
     
  
8、完全恢复的步骤
     1)restore :转储datafile
     2)recover:利用归档日志和当前的redo 做recover

9、recover database:当大部分datafile丢失,只能mount状态下
    recover tablespace:tablespace 的数据文件都丢失了,在open状态
    recover datafile :当单个datafile丢失,可以在mount 或 open 状态

10、恢复过程查看的视图:
    1)v$recover_file:查看需要恢复的datafile
    2)v$recovery_log: 查看recover 需要的redo 日志
    3)v$archvied_log:查看已经归档的日志

 1、 media failure 丢失大部分数据文件
