ORA-27612: Smart I/O failed due to a block corruption detected on the cell “string”. disk: “string”, block: “string”, disk offset: “string” ORACLE 报错 故障修复 远程处理

文档解释

ORA-27612: Smart I/O failed due to a block corruption detected on the cell “string”. disk: “string”, block: “string”, disk offset: “string”

Cause: The data block indicated was found to be corrupted on the cell.

Action: This may be due to a software error or a real data corruption. Analyze the segment. If there is indeed a block corruption, try to restore the block using RMAN block level recovery. If there is a trace file, report the errors in it to Oracle Support Services. If analyze did not report an error, report the problem to Oracle Support Services as this appears to be a software error.

ORA-27612:称为“Smart I/O不足”的错误,表明硬盘的某个块已发现损坏。它在运行Smart I/O命令时触发,最常用于Alter Table Move操作。该行跟踪相关的块,磁盘偏移,磁盘大小等信息。

官方解释

该错误表示Oracle在尝试进行Smart I/O应用操作时,检测到硬盘上的某个块损坏,从而无法完成操作。

常见案例

首先,当您尝试使用ALTER TABLE MOVE或SQL*LOADER等操作来处理数据时,可能会出现“Smart I/O不足”错误。还可能会导致此错误的服务器或硬盘设备故障。

一般处理方法及步骤

1.首先,检查服务器和磁盘设备是否正常。

2.然后,尝试用ALTER DATABASE DATAFILE AUTOEXTEND OFF来暂停自动扩展表空间,并保存系统表空间状态。

3.接着,拷贝出数据文件,并通过Oracle工具对拷贝的数据文件进行对比。

4.如果在步骤3中拷贝出的数据文件中找到了损坏块,则可以使用DBVERIFY来修复损坏的块。

5.如果没有找到损坏块,则可能需要移除无用的块并重新分配表空间,以便解决此问题。

6.最后,用ALTER DATABASE DATAFILE AUTOEXTEND ON激活自动扩展表空间并完成操作。
