朋友的数据库服务器出现ORA-00600[kcratr_nab_less_than_odr]，不能open数据库
1.open数据库报ORA-00600[kcratr_nab_less_than_odr]
SQL> ALTER DATABASE OPEN; ALTER DATABASE OPEN * 第 1 行出现错误: ORA-00600: 内部错误代码, 参数: [kcratr_nab_less_than_odr], [1], [99189], [43531], [43569], [], [], [], [], [], [], []
2.查看alert日志

3.查看trace文件

通过alert和trace中的内容可以知道，数据库需要恢复到rba到43569，但是因为某种原因实例恢复的时候，只能利用1 thread 99189 seq#，恢复rba到43531。从而导致数据库无法正常open
This Problem is caused by Storage Problem of the Database Files. The Subsystem (eg. SAN) crashed while the Database was open. The Database then crashed since the Database Files were not accessible anymore. This caused a lost Write into the Online RedoLogs and so Instance Recovery is not possible and raising the ORA-600.
4.解决方法
SQL> SELECT STATUS FROM V$INSTANCE; STATUS ------------ MOUNTED --尝试直接recover database SQL> RECOVER DATABASE ; ORA-00283: 恢复会话因错误而取消 ORA-00264: 不要求恢复 --提示不用恢复 --再打开数据库，还是kcratr_nab_less_than_odr错误警告 SQL> ALTER DATABASE OPEN; ALTER DATABASE OPEN * 第 1 行出现错误: ORA-00600: 内部错误代码, 参数: [kcratr_nab_less_than_odr], [1], [99189], [43531], [43569], [], [], [], [], [], [], [] --尝试不完全恢复 SQL> RECOVER DATABASE UNTIL CANCEL; ORA-10879: error signaled in parallel recovery slave ORA-01547: 警告: RECOVER 成功但 OPEN RESETLOGS 将出现如下错误 ORA-01152: 文件 1 没有从过旧的备份中还原 ORA-01110: 数据文件 1: 'D:\DBDMS\DATA\SYSTEM01.DBF' --重建控制文件 SQL> ALTER DATABASE BACKUP CONTROLFILE TO TRACE AS 'D:/1.TXT'; 数据库已更改。 SQL> SHUTDOWN IMMEDIATE; ORA-01109: 数据库未打开 已经卸载数据库。 ORACLE 例程已经关闭。 SQL> STARTUP NOMOUNT; ORACLE 例程已经启动。 Total System Global Area 417546240 bytes Fixed Size 2176328 bytes Variable Size 268438200 bytes Database Buffers 138412032 bytes Redo Buffers 8519680 bytes SQL> CREATE CONTROLFILE REUSE DATABASE "DBDMS" NORESETLOGS NOARCHIVELOG 2 MAXLOGFILES 16 3 MAXLOGMEMBERS 3 4 MAXDATAFILES 100 5 MAXINSTANCES 8 6 MAXLOGHISTORY 18688 7 LOGFILE 8 GROUP 1 'D:\DBDMS\LOG\REDO01.LOG' SIZE 50M BLOCKSIZE 512, 9 GROUP 2 'D:\DBDMS\LOG\REDO02.LOG' SIZE 50M BLOCKSIZE 512, 10 GROUP 3 'D:\DBDMS\LOG\REDO03.LOG' SIZE 50M BLOCKSIZE 512 11 DATAFILE 12 'D:\DBDMS\DATA\SYSTEM01.DBF', 13 'D:\DBDMS\DATA\SYSAUX01.DBF', 14 'D:\DBDMS\DATA\RBSG01.DBF', 15 'D:\DBDMS\DATA\DATA01.DBF', 16 'D:\DBDMS\DATA\INDX01.DBF', 17 'D:\DBDMS\DATA\DATA02.DBF', 18 'D:\DBDMS\DATA\DATA03.DBF', 19 'D:\DBDMS\DATA\DATA04.DBF', 20 'D:\DBDMS\DATA\INDX02.DBF', 21 'D:\DBDMS\DATA\SYSTEM02.DBF' 22 CHARACTER SET ZHS16GBK 23 ; 控制文件已创建。 --继续尝试恢复 SQL> RECOVER DATABASE ; 完成介质恢复。 SQL> ALTER DATABASE OPEN; 数据库已更改。 --open成功
在这次恢复中，主要就是重建控制文件，然后直接恢复成功，如果redo有损坏，那么可能需要使用不完全恢复，然后使用resetlogs打开数据库
