服务器断电重启导致备份生产环境的恢复目录库无法进行启动,提示Ora-01092例程终止。强行断开连接

SMON: terminating instance due to error 600

Instance terminated by SMON, pid = 2744

 

查找相关资料,发现RA-600[4913]错误的2个argument的含义, 该ORA-600[4913]属于内核undo事务模块

[1836] Undo record seq number

[1844] Redo record seq number

由于UNDO序列和REDO序列不一致引发错误。

解决办法:重建UNDO表空间,步骤如下:

C:/>set nls_lang=american_america.zhs16gbk

C:/>sqlplus "/ as sysdba"

在线drop损坏的rbs数据文件,然后重试打开数据库

 

SQL> drop tablespace rbs including contents;

drop tablespace rbs including contents

*

ERROR 在行 1:

ORA-01548: active rollback segment 'RBS0' found, terminate dropping tablespace

-- 报错ORA-01548,表明有活动回滚段

SQL> select segment_name,tablespace_name,status from dba_rollback_segs;

SQL> shutdown immediate

-- 正常关闭数据库加入隐含函数_corrupted_rollback_segments,修改参数文件加入隐含参数

_corrupted_rollback_segments=(RBS0,RBS1,RBS2,RBS3,RBS4,RBS5,RBS6)后以restricted模式打开数据库

SQL> startup restrict

强制删除所需要的回滚段

 

删除包含损坏回滚段表空间后,并开始建立回滚段表空间

 

查询回滚段状态

 

正常关闭数据库,并将参数文件中的隐含参数_corrupted_rollback_segments注释,并将ROLLBACK_SEGMENTS加入所有的回滚段。

 

正常启动数据库
