非归档模式下，current redo log丢失如何恢复？

ALLSTARS_ORACLE

环境：oracle 10g,windows平台，非归档模式，没有备份
测试：手工删除current redo log，尝试恢复

恢复思路：修改pfile文件，加入_allow_resetlogs_corruption=true参数，在数据库不一致的情况下，强制打开数据库，做数据库的全库导出。新建数据库，再将数据导入。

问题：可以强制打开数据库，但数据库会很快宕掉，exp根本来不及完成。alert日志里有大量ora-600报错。

兄弟们有没有好的办法，给个建议


数据库既然已经强制启动，此时再去掉_allow_resetlogs_corruption还对实例有影响么？
