drop tablesapce 数据恢复

发表于 2021 年 7 月 1 日 由 惜分飞

有客户执行了drop tablespace xxx including contents and datafiles,虽然删除命令返回错误,但是该表空间中大量对象被删除,文件没有被从系统层面删除

通过工具获取obj$字典信息，结合user$,判断业务用户表数据基本上全部删除
20210701193502

对于这类情况,常规方法无法恢复，只能按照表被drop的思路进行恢复.参考文章:dul恢复drop表测试,通过结合客户提供的表结构和一些特殊方法恢复出来所有对象的obj#,dataobj#信息,快速的恢复了客户数据,得到客户认可

asm磁盘组增加磁盘进行扩容之后报ORA-15335: ASM metadata corruption detected in disk group ‘DATA’和ORA-15196: invalid ASM block header [kfc.c:26368] [check_kfbh] [2147483648] [7] [2183628676 != 686982479],磁盘组dismount,然后mount之后立马dismount掉.

通过修复该错误,并且禁止reblance操作[增加磁盘数据需要重新分布],mount磁盘组,然后open库,发现redo已经被覆盖(非归档),强制打开库报错
