接手一个库,在open的过程中遭遇到ORA-600 2662错误

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

通过dbv检查system数据文件

对于这样问题,通过Oracle Recovery Tools实战批量坏块修复,实现数据库可以完美导出数据
