win文件系统损坏oracle恢复
有客户反馈数据文件无法拷贝也无法正常操作,通过查看系统日志发现ntfs文件系统异常

在文件系统中看数据文件状态正常,但是拷贝文件报错

通过恢复工具查看文件发现文件大小为0kb

通过文件系统层面扫描,然后进行相关数据恢复,依旧报错(恢复文件大小错误)

经过进一步人工修复文件系统目录,实现数据完整恢复,实现数据0丢失

基于这种情况如果通过文件系统层面无法恢复,对于此类oracle block级别进行处理,类似以前恢复case:
dbca删除库和rm删库恢复
文件系统损坏导致数据文件异常恢复
Oracle 数据文件大小为0kb或者文件丢失恢复
asm disk 磁盘部分被清空恢复
由于未知原因导致磁盘组的一个磁盘前面1G被置空(data磁盘组一共5个1T磁盘,第一个盘未知原因置空了1G数据)

通过分析disk 1和disk 2的前面1001MB数据,以及asm的数据分布特性,可以确认丢失的1000MB数据为39号文件的数据(和客户当时这个库是通过rman还原过来的操作有关系)


对于这样的情况,通过底层扫描,可以很好的恢复数据,参考以前类似文章
asm disk被加入vg恢复
asm disk header 彻底损坏恢复
asm磁盘dd破坏恢复
通过底层恢复,恢复结果如下

dbv检查数据文件

然后把数据库恢复出来数据文件中的数据恢复到新库中,至此完成该case恢复

经过一些处理之后resetlogs 成功,但是悲剧产生了(客户之前自己重建过ctl,遗漏大量数据文件,然后我参照客户的ctl进行处理)使得新的ctl中遗漏的很多数据文件,库被resetlogs打开,导致部分文件的resetlog scn不一致,另外数据库还有ORA-600 4137错误需要处理
