一、数据库启动异常
网友因异常断电导致数据库不能正常启动，处理过程记录
1、sqlplus中提示

C:\Documents and Settings\Administrator>sqlplus "/as sysdba"

2、alert日志文件

二、查询是损坏日志组

SQL> col member for a35
SQL> select a.group#,a.status,b.member from v$log a,v$logfile b
   2 where a.group#=b.group#;
    GROUP# STATUS           MEMBER
---------- ---------------- -----------------------------------
         3 CURRENT          R:\ORADATA\HZYL\REDO03.LOG
         2 INACTIVE         R:\ORADATA\HZYL\REDO02.LOG
         1 INACTIVE         R:\ORADATA\HZYL\REDO01.LOG

确定是因为断电导致当前redo 损坏，需要使用隐含参数+不完全恢复处理(经验)

三、不完全恢复

SQL> recover database until cancel;
ORA-00279: 更改 9743796718 (在 12/05/2011 09:07:40 生成) 对于线程 1 是必需的

OSD-04002: 无法打开文件
O/S-Error: (OS 2) 系统找不到指定的文件。
ORA-01547: 警告: RECOVER 成功但 OPEN RESETLOGS 将出现如下错误
ORA-01194: 文件 1 需要更多的恢复来保持一致性
ORA-01110: 数据文件 1: 'R:\ORADATA\HZYL\SYSTEM01.DBF'

四、启用隐含参数，尝试打开数据库

SQL> create pfile='d:/1.txt' from spfile;
文件已创建。
#############添加隐含参数##################
*._allow_resetlogs_corruption=TRUE
*._allow_error_simulation=TRUE
##########################################
SQL> shutdown immediate
ORA-01109: 数据库未打开

SQL> startup pfile ='d:\1.txt';
ORACLE 例程已经启动。

ORA-01589: 要打开数据库则必须使用 RESETLOGS 或 NORESETLOGS 选项

第 1 行出现错误:

五、查看alert日志

这里看到熟悉的ora-600 [2662]，处理方法增加scn，参考ORA-00600 [2662]

六、增加SCN，打开数据库

打开过程中，出现ORA-00600[2256]，但是数据库还是正常打开，具体原因待研究
