ORA-00600 [2662][][][][][] 错误解决

今天给客户做数据恢复，发现必须使用隐藏参数_allow_resetlogs_corruption，结果一用报出了ORA-00600 2662的错误。

客户那边说丢失了一个数据文件CUUG.DBF，只有一个以前的冷备份（结果就备份了这一个数据文件............#@#@￥...）。接管客户系统时，那边dba已经将控制文件重建了。无语中......

将以前的数据文件拷贝回来，重新注册归档日志后，开始恢复。报错：    

提示ORA-01547: warning: RECOVER succeeded but OPEN RESETLOGS would get error below
ORA-01194: file 1 needs more recovery to be consistent
ORA-01110: data file 1: '/opt/Oracle/product/10.2.0/oradata/orcl1/system01.dbf'
看下数据文件的SCN：  

SQL> select  CHECKPOINT_CHANGE# from v$datafile_header;

CHECKPOINT_CHANGE#
------------------ 
    591931
    591931
    591931
    591931
    505927
然后看下归档日志：

/opt/oracle/product/10.2.0/flash_recovery_area/ORCL1/archivelog/2012_05_19/o1_mf_1_9_7vh78q75_.arc   591800       591805

这眼看普通恢复没戏了.....归档日志不连续。

开启隐藏参数

sql> alter system set "_allow_resetlogs_corruption"=true scope=spfile;

再次尝试打开数据库，开始提示ORA-00600错误了。
