Oracle备份恢复之断电导致控制文件和日志文件损坏修复

Oracle数据库遭遇断电遭遇ora-00214、ora-00314、ora-00312错误恢复案例一枚

1、数据库在17日21:19启动开始报错ora-214错误：

Tue Jan 17 21:19:10 2017

alter database mount exclusive

Tue Jan 17 21:19:13 2017

ORA-214 signalled during: alter database mount exclusive...

Dump file d:\oracle\product\10.2.0\admin\orcl\bdump\alert_orcl.log

2、从控制文件看目前controlfile文件信息如下：

control_files            = D:\ORACLE\PRODUCT\10.2.0\ORADATA\ORCL\CONTROL01.CTL, D:\ORACLE\PRODUCT\10.2.0\ORADATA\ORCL\CONTROL02.CTL, D:\ORACLE\PRODUCT\10.2.0\ORADATA\ORCL\CONTROL03.CTL

3、从sqlplus界面看到CONTROL01.CTL的版本号低于CONTROL02.CTL版本号，根据规则、保留高版本CONTROL文件原则尝试重新启动数据库：

修改参数文件中控制文件信息如下：

control_files            = D:\ORACLE\PRODUCT\10.2.0\ORADATA\ORCL\CONTROL02.CTL, D:\ORACLE\PRODUCT\10.2.0\ORADATA\ORCL\CONTROL03.CTL

尝试重新启动数据库，成功进入mount状态。
