ORA-01193: file string is not the same file seen at start of recovery ORACLE 报错 故障修复 远程处理

文档解释

ORA-01193: file string is not the same file seen at start of recovery

Cause: A different copy of the file was accessed the last time media recovery looked at the file header. A backup of the file was restored or the meaning of the file name changed during recovery.

Action: Ensure the correct file is available, then retry recovery.

该错误代表ORACLE在执行instance恢复时识别到一个文件发生改变,即ORACLE在恢复过程中发现这个文件自从上次实例恢复以来一直没有改变,但却在恢复过程中意外发现这个文件已经改变了。

官方解释

常见案例

正常处理方法及步骤

一、检查数据库当前的状态

1.了解当前数据库状态,包括open、mount、close、nomount等状态,以确定目前状态

2.确定数据库被open或mount了,还未持久化恢复

二、关闭故障数据库,并重新开启即可

1.如果是open状态,则使用shutdown immediate功能关闭数据库

2.如果是mount状态,则使用alter database close immediate功能关闭数据库

3.重新开启数据库,并开始恢复

4.确保备份文件一致性状态保存,避免再次出现一次恢复中文件改变的错误
