Ora-00600 4194错误的解决方法
2007-12-22 22:27:30 来源:WEB开发网
问题:我的数据库重新启动后,出现了Ora-00600 4194错误,具体的日志如下:
Sat Jan 21 13:55:21 2006
Errors in file /opt/oracle/admin/conner
/bdump/conner_smon_17113.trc:
ORA-00600: internal error code, arguments:
[4194], [43], [46], [], [], [], [], []
Sat Jan 21 13:55:21 2006
Errors in file /opt/oracle/admin/conner
/udump/conner_ora_17121.trc:
ORA-00600: internal error code, arguments:
[4194], [45], [44], [], [], [], [], []
请问应该用什么办法解决?
答:具体的解决办法是通过备份来进行恢复,因为Ora-00600 4194错误的出现说明UNDO段出现了问题,如果你没有备份,业可以通过特殊的初始化参数进行强制启动,下文针对Oracle的隐含参数进行恢复说明(由于你的实际情况可能会有所出入,所以请你进行测试前先行备份)。
◆首先你需要确定当前的回滚段名称,注释:(可以从alert文件中获得)
Sat Jan 21 13:55:21 2006
Undo Segment 11 Onlined
Undo Segment 12 Onlined
Undo Segment 13 Onlined
Successfully onlined Undo Tablespace 16.
◆注意:对应的AUM (auto undo management) 下的回滚段名称为:
'_SYSSMU11$','_SYSSMU12$','_SYSSMU13$'
◆此时你可以修改init.ora参数文件,使用Oracle隐含参数_corrupted_rollback_segments将回滚段标记为损坏,然后启动数据库,Oracle则会跳过对于这些回滚段的相关操作,强制启动数据库。
._corrupted_rollback_segments='_SYSSMU11$','_SYSSMU12$','_SYSSMU13$'
◆然后使用init.ora参数文件启动数据库:
[oracle@jumper dbs]$ sqlplus "/ as sysdba"
SQL*Plus: Release 9.2.0.4.0 - Production on Sat Jan 21 13:56:47 2006

◆注意观察alert文件所获得的如下信息:
