回滚段表空间损坏处理（ORA-01552）
OS :XP
DB:9201
本测试测试了如下情况：
a.正常关闭数据库，数据库（未）归档，回滚段表空间丢失，成功恢复
b.非正常关闭数据库，数据库非归档，有活动事务，回滚段表空间丢失，成功恢复
c.非正常关闭数据库，数据库归档，有活动事务，回滚段表空间丢失，恢复失败，目前不知原因
a.正常关闭数据库, 数据库(未)归档
如shutdown normal,shutdown immediate
1.正常关闭数据库，模拟回滚段表空间丢失

已连接。
SQL> shutdown immediate;
数据库已经关闭。
已经卸载数据库。
ORACLE 例程已经关闭。
SQL> host del D:oracleoradatajumperUNDOTBS01.DBF
SQL> startup

怪了，归档模式恢复不成功，而非归档模式恢复成功?
从后台日志来看，归档模式下用序列为28的日志作了介质恢复，然后将此日志归档后，报了启动错误
是不是归档进程后，数据库仍然去读老的回滚表空间,造成打开数据库不
