标题：21c数据库恢复遭遇ora-600 ktugct: corruption detected
作者：惜分飞©版权所有[未经本人同意,不得以任何形式转载,否则有进一步追究法律责任的权利.]
接手一个oracle 21c的库恢复请求,通过Oracle数据库异常恢复检查脚本(Oracle Database Recovery Check)脚本检测之后,发现undo文件offline之后,做了resetlogs操作,导致该文件目前处于WRONG RESETLOGS状态
尝试恢复数据库ORA-16433错误
SQL> recover datafile 1; ORA-00283: recovery session canceled due to errors ORA-16433: The database must be opened in read/write mode.
2025-03-11T12:07:43.381296+08:00 ALTER DATABASE RECOVER datafile 1 2025-03-11T12:07:43.381296+08:00 Media Recovery Start 2025-03-11T12:07:43.381296+08:00 Media Recovery failed with error 16433 ORA-283 signalled during: ALTER DATABASE RECOVER datafile 1 ...
官方对于该错误的解释
[oracle@iZbp11c0qyuuo1gr7j98upZ ~]$ oerr ora 16433 16433, 00000, "The database must be opened in read/write mode." // *Cause: An attempt was made to open the database in read-only mode after an // operation that requires that the database be opened in read/write // mode. // *Action: Open the database in read/write mode. The database can then be // opened in read-only mode.
对于该错误,可以通过rectl进行解决,但是由于undo文件的resetlog 信息不对,无法直接重建ctl,这种情况下,通过Oracle Recovery Tools小工具对undo文件的resetlogs信息今星期修改
然后重建ctl成功
