ORA-01157: cannot identify/lock data file string – see DBWR trace file ORACLE 报错 故障修复 远程处理

文档解释

ORA-01157: cannot identify/lock data file string – see DBWR trace file

Cause: The background process was either unable to find one of the data files or failed to lock it because the file was already in use. The database will prohibit access to this file but other files will be unaffected. However the first instance to open the database will need to access all online data files. Accompanying error from the operating system describes why the file could not be identified.

Action: Have operating system make file available to database. Then either open the database or do ALTER SYSTEM CHECK DATAFILES.

这个错误是指Oracle无法确定或解锁指定的数据文件。这通常是由于一系列内部故障原因而引起的,可能由于Oracle无法访问此文件,可能意味着该文件的内容被破坏。

官方解释

ORA-01157:在定位/锁定数据文件时发生错误(表示无法确定/解锁指定的数据文件)。

常见案例

1.数据文件或控制文件损坏导致无法锁定或打开数据文件。

2.存储在磁盘上的数据文件被修改,使得Oracle无法访问它。

3.当改变数据文件的位置时,将data file声明错误,系统无法找到数据文件。

正常处理方法及步骤

1.使用操作系统检查指定的数据文件,确保其可用且损坏程度小。

2.尝试另一种对数据文件的访问,查看是否可以访问它。

3.如果数据文件被破坏,请备份并重置它,然后重新恢复它。

4.检查数据库和控制文件,以确保它们未被意外改变。
