Oracle数据恢复-慎用OEM误操作数据文件删除案例 有需要学习的朋友可参考一下。

一个彻底的包含数据文件和内容的集联删除被发出,如果使用手工,恐怕DBA们都会极其慎重的拼写这样的命令:

Wed May 02 10:46:09 2012
/* OracleOEM */ DROP TABLESPACE "WNDT" INCLUDING CONTENTS  AND DATAFILES  CASCADE CONSTRAINTS
Wed May 02 10:46:23 2012
Errors in file d:oracleadminwndtudumpwndt_ora_4816.trc:
ORA-01259: 无法删除数据文件 D:ORACLEORADATAWNDTWNDT.ORA
ORA-27056: skgfrdel: 无法删除文件
OSD-04024: 无法删除文件。
O/S-Error: (OS 32) 另一个程序正在使用此文件,进程无法访问。


似乎幸运的是,初始的删除遇到错误,显示文件被其他进程持有,无法删除。

但是遗憾的是,进一步的提示显示,文件最终被成功操作删除:

 代码如下 复制代码


Wed May 02 10:46:23 2012
Completed: /* OracleOEM */ DROP TABLESPACE "WNDT" INCLUDI


这则案例警示我们:尽量少用OEM等图形工具进行数据库重要的管理和维护操作,如果你不清楚前台的一个操作在后台会如何执行,那么一定要谨慎使用这样的工具。

对于这样的案例,如果用户能够及时的保护现场,通过存储级别的恢复是可以找回数据文件的。
