ORA-01171: 数据文件  因高级检查点错误而将脱机

oerr ora 1171
01171, 00000, "datafile %s going offline due to error advancing checkpoint"

适用于:

Oracle Database – Enterprise Edition – 版本 8.1.7.4 到10.2.0.1 [Release 8.1.7 到 10.2]
本文信息适用于任何平台。
症状
在读数据文件头时报告的损坏。

警报日志显示信息如:

ORA-01171: datafile 8 going offline due to error advancing checkpoint
ORA-01122: database file 8 failed verification check
ORA-01110: data file 8: ‘/oracle/test_lob12.dbf’
ORA-01251: Unknown File Header Version read for file number 8

ORA-01186: file 8 failed verification tests

 

原因

块文件头损坏(块1)。

这可能由于丢失的读或写,硬件问题,对Oracle的外部操作覆盖在块文件头中的内容导致的。

解决方案

方案 1:  从备份中还原数据文件

数据库需要在归档日志模式中。

使有问题的数据文件脱机,从备份中还原它,应用媒体恢复并重新将其设为联机:

SQL> alter database datafile <fileno> offline ;

在OS级别重命名文件(mv <original name> <original name_old>)

从备份中还原数据文件(rman 或使用受管理的备份)

恢复数据文件

SQL> alter database datafile <fileno> online;

 

方案 2:  数据文件的备份不可用,但从数据文件创建日期起的所有归档日志可用。

  1. 数据库必须在归档日志模式。
  2. 需要从数据文件被创建起所有的归档日志文件。
  3. 控制文件有数据文件创建信息。如果控制文件在数据文件被创建后重建,则下面的解决方案不起作用和步骤2将显示错误ORA-01178。

操作步骤:

步骤 1:

使有问题的数据文件脱机。

SQL> alter database datafile  ‘/oracle/test_lob12.dbf’ offline;

将文件复制到另外的备份位置。

步骤 2:

发出以下命令来重建文件:

SQL> alter database create datafile   ‘/oracle/test_lob12.dbf’;

步骤 3:

开始应用归档日志文件来重建数据文件。

SQL> Recover  datafile  ‘/oracle/test_lob12.dbf’;

步骤 4:

当恢复完成,使数据文件联机。

SQL> alter database datafile ‘/oracle/test_lob12.dbf’ online;

 

方案 3:  数据文件备份和归档日志不可用

解决方法是脱机数据文件并drop表空间:

alter database datafile ‘<file name and path>’ offline drop;
alter database open; (if the instance is down)
drop tablespace <tablespace name> including contents;
