特殊恢复ORA-00600 kcratr_nab_less_than_odr

特殊恢复ORA-00600 kcratr_nab_less_than_odr

故障原因：由于中午公司突然断电导致的测试服务器一台机器down机，然后重新启动的时候oracle startup不了了，

    随之出现600错误

系统：Solaris11 amd64

Oracle Database 12c Enterprise Edition Release 12.1.0.1.0 - 64bit Production

SQL> ALTER DATABASE OPEN; #open数据库

ALTER DATABASE OPEN

*

第 1 行出现错误:            //不能open数据库，抛出错误600

ORA-00600: 内部错误代码, 参数: [kcratr_nab_less_than_odr], [1], [99189],

[43531], [43569], [], [], [], [], [], [], []

alert log记录如下：

alter database open

Wed Jul 24 08:46:25 2013

Beginning crash recovery of 1 threads

 parallel recovery started with 3 processes

Wed Jul 24 08:46:25 2013

Started redo scan

Wed Jul 24 08:46:26 2013

Completed redo scan

 read 2521 KB redo, 0 data blocks need recovery

Errors in file /oracle/diag/rdbms/aaa/aaa/trace/aaa_ora_1873.trc  (incident=9781):  //错误事件在这个地方，要求您移步了意思是！！！

ORA-00600: 内部错误代码, 参数: [kcratr_nab_less_than_odr], [1], [111], [20030], [20227], [], [], [], [], [], [], []

cat /oracle/diag/rdbms/aaa/aaa/trace/aaa_ora_1873.trc文件结果如下

WARNING! Crash recovery of thread 1 seq 111 is ending at redo block 20030 but should not have ended before

redo block 20227        //此处的意思是数据库需要恢复rba到20227，但是只找到thread 1 seq 111能恢复rba到20030 所以数据库无法启动

DDE: Problem Key 'ORA 600 [kcratr_nab_less_than_odr]' was flood controlled (0x2) (incident: 9781)

ORA-00600: 内部错误代码, 参数: [kcratr_nab_less_than_odr], [1], [111], [20030], [20227], [], [], [], [], [], [], []

既然是直接恢复不了那就

SQL> RECOVER DATABASE; #同步redo日志的时间点

ORA-00283: 恢复会话因错误而取消

不要求恢复

SQL> RECOVER DATABASE UNTIL CANCEL; //不完全恢复

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: '/oracle/oradata/aaa/system01.dbf'  //此时感觉好凄凉啊！！！

既然控制文件的记录和rba不配合，然后rba恢复不了，所以决定从ctl文件下手处理此问题

重建控制文件

SQL> ALTER DATABASE BACKUP CONTROLFILE TO TRACE AS '/tmp/crlfile.txt';

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。

参考以生成的crl text，编写一下脚本

我的ctlfile.txt内容如下：

此处略去n个字...............

将STARTUP NOMOUNT(不包扩本身)字符后边的全部粘贴，到sqlplus下如下：
