Performing User-Managed Database-18.5、Restoring Control Files

18.5、Restoring Control Files

18.5.1、Restore Lost Copy of a Multiplexed Control File
18.5.1.1、Copying a Multiplexed Control File to a Nondefault Location
如果丢失控制文件的磁盘和文件系统不能再关联,那么必须改动CONTROL_FILES初始化參数来表明丢失的控制文件的新位置。
(1)数据库读或写控制文件直接shutdown
(2)拷贝正确的控制文件到指定的位置
(3)改动CONTROL_FILES初始化參数
(4)启动,mount,open数据库
模拟1、某块磁盘介质失败,丢失了控制文件,把控制文件放到一个新的位置

18.5.2、Restore Control File from Backup After Loss of All Current Control Files--即二进制控制文件
如果一个永久的介质失败损坏了全部控制文件。有控制文件的备份。能够完毕还原控制文件。

控制文件不能訪问。能够启动实例,可是不能mount数据库。

直到控制文件能够再次訪问
数据库才干mount和open。还原一个备份的控制文件,必须alter database open resetlogs。


还原控制文件的过程依赖于重做日志是否可用(是否存在):

模拟1、创建控制文件的trace文件,表空间testtbs01创建表test01,然后多次切换日志,备份归档日志,删除全部控制文件
