公司某系统的Oracle 8.1.7数据库突然非正常关闭，经检查回滚段数据文件损坏，准备恢复的时候又发现备份无效（管理员修改数据库密码没有修改相应的备份脚本导致），数据库采用归档日志模式。部分系统描述如下：
init.ora
rollback_segments = ( RBS01,RBS02, RBS03, RBS04, RBS05, RBS06, RBS07, RBS08, RBS09, RBS10 ,RBS11, RBS12, RBS13, RBS14, RBS15, RBS16, RBS17, RBS18, RBS19, RBS20, RBS21, RBS22, RBS23, RBS24 )
其中RBS02, RBS03, RBS04, RBS05, RBS06, RBS07, RBS08, RBS09, RBS10 ,RBS11, RBS12, RBS14, RBS15, RBS16, RBS17, RBS18, RBS19, RBS20, RBS21, RBS22, RBS23回滚段状态为“需要恢复”，经检查数据文件目录
-rw-r----- 1 oracle dba2147491840 11月 27 22:55 rbs01.dbf
-rw-r----- 1 oracle dba2147491840 11月 27 14:22 rbs02.dbf
-rw-r----- 1 oracle dba7717527552 11月 27 22:53 rbs03.dbf
其中rbs02.dbf 文件损坏。
而且检查：

F 2> ROM V$LOG V1, V$LOGFILE V2
W 3> HERE V1.GROUP# = V2.GROUP#;
GROUP# MEMBER

根据MetaLink文档，需要联系Oracle Support，不知道大家是否碰过类似案例，是否能全部或部分恢复，谢谢！ |
