Error 600 happened during db open, shutting down database

USER (ospid: 1590): terminating the instance due to error 600

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
