根据这些年的恢复经验,恢复过相关错误的主要有:
ORA-01092 ORA-00704 ORA-00942
Oracle 11g丢失access$恢复方法
11.1.0.7版本也会出现access$表丢失导致数据库无法启动
总结主要两类:1. 由于某种bug导致access$表丢失的故障,另外一种是由于坏块导致数据库核心基表损坏引起,对于这个库进行分析

dbv 检查坏块

0kb数据文件恢复或者文件丢失恢复

Posted on by

接到一个朋友恢复请求,由于rose频繁切换导致文件系统部分数据文件变化为0kb和文件丢失.
故障现象
部分数据文件变化为0kb和文件丢失.
file_lost
file_size_0

这里比较明显,数据库的users03变为了0kb和users04丢失.数据库alert日志报错信息如下:

Fri May 04 09:35:10 2018

alert日志的报错也比较明显,users03是文件超过了大小(大小为0kb,读取之后肯定超过大小),users04提示无法打开文件(文件在文件系统层面已经丢失).现在问题比较明显由于文件系统故障导致文件大小为0和丢失

碎片扫描恢复
常规的方法肯定无法恢复,比较好的方法只能是底层碎片扫描重组,结合多种扫描工具,最后发现一个做底层恢复的朋友的工具效果不错,扫描结果如下
file_scan

通过工具分析坏块情况

这里通过分析恢复的两个文件总的block数量2511618，其中连续损坏7271个block损坏,由于出现问题之后,数据库被offline这两个文件继续启动运行了几个小时,导致少量block被覆盖,恢复软件直接置空.后续的恢复比较顺利,正常open数据库,然后处理坏块对象(正好不是业务核心表的lob字段,所有部分丢失影响不是非常大).

温馨提醒:
1. 数据文件和备份不要放在同一个阵列上,更不能是同一个分区（卷）上
2. 出现此类问题之后,应当理解停止对该分区的任何写操作,方式丢失或者大小为0的文件被覆盖.
