oracle11.2 异常关闭机器引起,ora-01172,ora-01152错误处理

在突然断电后重启数据库 如果数据库业务逻辑处理频繁,往往引发错误。有简单的数据文件坏块,有些会引起内核错误,一般通过redo日志恢复都可以恢复正常状态

错误例子一:需要恢复数据文件

 重新启动出现 ora-01172,ora-01151错误
SQL> startup
ORACLE instance started.

查看ora-01172错误描述
oerr ora 01172

[oracle@localhost ~]$ oerr ora 01172
01172, 00000, "recovery of thread %s stuck at block %s of file %s"
// *Cause: Crash recovery or instance recovery could not apply a change to a
//         block because it was not the next change. This can happen if the
//         block was corrupted and then repaired during recovery.
// *Action: Do a RECOVER DATAFILE for the file containing the block. If this
//         does not resolve the problem then restore the file from a backup
//         and  recover it.
[oracle@localhost ~]$ sqlplus / as sysdba

SQL> recover datafile 3;
Media recovery complete.
SQL> alter database open;

Database altered.

SQL> select name,open_mode from v$database;

NAME      OPEN_MODE
--------- --------------------

SQL> shutdown immediate
Database closed.
Database dismounted.
ORACLE instance shut down.
SQL> startup


错误例子二:引起看不到的内核错误

重启出现 ORA-00600: internal error code, arguments: [kcratr_scan_lastbwr], [], [], [], [], [], [], [], [], [], [], []
