12C sysaux 异常恢复—wrong resetlogs 错误恢复

有朋友请求支援,他们数据库由于file 3 大量坏块,然后直接使用rman 备份还原了file 3,但是在recover过程中发现归档丢失,而且整个库在丢失归档的scn之后,还做过resetlogs操作,导致现在整个库无法正常启动,报ORA-01190错误,希望帮忙把file 3 给online起来,整个库正常open【当然在丢失sysaux的情况下,数据库可以open起来,但是这种情况下,迁移数据比较麻烦】

数据库遭遇ORA-16433,此类方法无法打开数据库,根据经验值出现此类问题,可能需要重建控制文件,但是由于其中file 3的resetlogs scn不正确,无法包含该文件重建控制文件

ORA-01202: 此文件的原型错误 - 创建时间错误

这里比较明显ORA-01202,由于创建控制文件之时没有file 3信息,因此导致控制文件中关于file 3的信息和该文件头的创建时间不一致(此处之时显示了时间不一致,如果通过bbed修改时间,后续可能还有很多东西不一致,因此通过bbed 一个个修改一个个尝试,理论可行,但实际可操作性不好),因此尝试直接使用bbed修改file 3文件头(由于是win环境,操作稍微麻烦点),把resetlogs信息修改和其他的一样

_allow_resetlogs_corruption和adjust_scn解决ORA-01190

一、模拟offline文件然后resetlogs操作

1.设置datafile 5数据文件offline
2.rman备份数据库
3.关闭原数据库,删除数据文件/当前日志和部分归档日志
4.执行不完全恢复,resetlogs打开数据库(如下面操作)

bbed解决ORA-01190

当我们使用resetlogs方式打开数据库后,发现有数据文件处于offline状态,这个时候很可能就是悲剧降临的时候,很有可能这个文件文件在resetlogs之前就处于offline状态,然后你resetlogs之后,这个文件使用常规方法很难再online,会出现ORA-01190或者ORA-01189之类的错误。
一、模拟offline文件然后resetlogs操作

1.设置datafile 5数据文件offline
2.rman备份数据库
3.关闭原数据库,删除数据文件/当前日志和部分归档日志
4.执行不完全恢复,resetlogs打开数据库(如下面操作)

二、bbed修改相关项

下面两项与resetlogs相关
kcvfhrlc表示 reset logs count
kcvfhrls表示 resetlogs scn
下面四项与数据库文件scn相关
kscnbas (at offset 140) – SCN of last change to the datafile.
kcvcptim (at offset 148) - Time of the last change to the datafile.
kcvfhcpc (at offset 176) – Checkpoint count.
kcvfhccc (at offset 184) – Unknown, but is always 1 less than thecheckpoint point count.
