由于系统故障,导致操作系统进入,客户通过其他方式进入系统拷贝出来数据文件,redo,ctl等文件,安装版本相同的数据库,修改相关路径,启动数据库,但是启动报错,让我们给予技术支持.数据库open报ORA-600 2662错误

Use ADRCI or Support Workbench to package the incident. See Note 411.1 at My Oracle Support for error and packaging details. Errors in file /home/oracle/app/oracle/diag/rdbms/orcl/orcl/trace/orcl_ora_22446.trc: ORA-00600: internal error code, arguments:[2662],[2],[2313731573],[2],[2313735660],[12583040],[],[],[],[],[],[] Errors in file /home/oracle/app/oracle/diag/rdbms/orcl/orcl/trace/orcl_ora_22446.trc: ORA-00600: internal error code, arguments:[2662],[2],[2313731573],[2],[2313735660],[12583040],[],[],[],[],[],[] Error 600 happened during db open, shutting down database USER (ospid: 22446): terminating the instance due to error 600
这个错误比较常见,特别是使用了_allow_resetlogs_corruption屏蔽一致性强制拉库的时候.解决该问题比较简单,修改数据库scn,然后open数据库成功,参考部分案例_allow_resetlogs_corruption
