客户尝试重建ctl进行恢复,结果由于分析不正确,导致在重建ctl的时候,遗漏了3个数据文件,并且在屏蔽一致性的情况下,强制resetlogs操作,结果数据库没有被正常打开,而是报ORA-600 2662错误

操作到这里,后续问题就比较麻烦了,因为在asm磁盘组中数据文件重建ctl的时候遗漏3个并且还被resetlogs操作过,导致这三个文件的resetlogs scn和其他数据文件不一致,对于这个问题,解决办法通过Oracle Recovery Tools工具或者bbed修改相关resetlogs scn,然后重建ctl

SQL> @rectl.sql

Control file created.

SQL> RECOVER DATABASE;
Media recovery complete

然后解决之前数据库启动报ORA-600 2662问题,通过修改数据库scn进行解决,可以使用Patch_SCN工具进行快速解决,然后open数据库成功

SQL> ALTER DATABASE OPEN;
 
Database altered.

但是查看alert日志数据库报大量ORA-600 4194、ORA-01595和Exception [type: SIGSEGV, Address not mapped to object] [ADDR:0xC21D511] [PC:0x97F4EFA, kgegpa()+40]之类错误

客户自行恢复到这一步,后面无法处理,接手之后进行恢复，其实后面比较简单了，就是修改下数据库scn,数据库就可以open起来,然后处理异常的undo和对象即可,可以参考以前类似文章:

然后客户使用备份的system01.dbf文件替换了被resetlogs之后文件,导致数据库后续操作无法继续

SQL> recover database;
ORA-00283: recovery session canceled due to errors
ORA-19909: datafile 1 belongs to an orphan incarnation
ORA-01110: data file 1: '/data/OracleData/xff/system01.dbf'

这个问题比较简单,通过bbed或者Oracle Recovery Tools修改文件头相关信息,然后open数据库成功
重建控制文件丢失数据文件导致悲剧
Oracle Recovery Tools快速恢复ORA-19909

SQL> recover datafile 1;
Media recovery complete.
SQL> recover database;
Media recovery complete.
SQL> alter database open;

Database altered.

但是由于system文件有大量坏块导致数据库无法正常登录和导出
