数据库当前日志坏了，强制打开不能成功，求救？？

处理结果

1、执行以下语句报错
SQL> alter session set events 'IMMEDIATE trace name ADJUST_SCN level 1';
ERROR:
ORA-00600: internal error code, arguments: [kcsadjn1], [], [], [], [], [], [],
[]
这个错误在metalink上查了查没有找到。
直接打开数据库还是报错
SQL> alter database open;
alter database open
*
ERROR at line 1:
ORA-00600: internal error code, arguments: [2662], [0], [1186518378], [0],
[1186662232], [12582914], [], []

再执行一次，还是报错
SQL> alter session set events 'IMMEDIATE trace name ADJUST_SCN level 1';
ERROR:
ORA-00600: internal error code, arguments: [2662], [0], [1186518378], [0],
[1186662232], [12582914], [], []

SQL> alter database open;
ERROR:
ORA-03113: end-of-file on communication channel
2、shutdown 和s

环境：solaris8 ,oracle 8.1.6
没有备份和归档
机器突然掉电，数据库重新启动报错
有三个日志组，每组一个日志文件
1、
报错：
SVRMGR> alter database open;
alter database open
*
ORA-00368: checksum error in redo log block
ORA-00353: log corruption near block 237640 change 1186662514 time 11/09/2005 19:58:10
ORA-00312: online log 3 thread 1: '/ora_expredo1/redo03.log'

2、
因为没有备份和归档，只有清空日志组，执行如下命令,但不能成功。
SQL> ALTER DATABASE CLEAR UNARCHIVEDLOGFILE GROUP 3 ;
*
ERROR at line 1:
ORA-01624: log 3 needed for crash recovery of thread 1
ORA-00312: online log 3 thread 1: '/ora_expredo1/redo03.log'
3、使用隐含参数_allow_resetlogs_corruption=true，强制打开
startup mount
recover database until cancel;
alter database open resetlogs;
报错：
SQL> alter database open resetlogs;
alter database open resetlogs
*
ERROR at line 1:
ORA-00603: ORACLE server session terminated by fatal error

4、重新启动数据库
SQL> startup restrict
ORACLE instance started.
