About the daul:
Someone said even if u have dropped a table, though the data still exists in the datafile, u can use dual to unload the data
And once i see from the newgroup that even if u have the data physicallhy stored in the database, if u have dropped it from the dictionary , u fcannot recover it through that tool.
Is it right?

[B]看来你还是没看清楚我给你的URL,做recover至少需要apply一个日志文件,我已经指出:
1.backup control file,redo log file,datafile
2.recreate controlfile
3.recover database using backup controlfile
使用当前redo log apply (!!!!)
4.alter database open resetlogs;
你只是cancel肯定不行,另外_allow_resetlogs_corruption=true 没到万不得已决不要使用,因为像你这种错误应该都是可以解决的,既然你已经使用,并且出现了600错误,你只能再:
shutdown immediate
startup
如果能起来,exp后,重建db,imp
如果起不来,你的数据库数据又很重要的话,既然你在广州,联系
广州Oracle Support,他们有DUL工具,让他们帮你把数据抓出来,这是最后的办法。 [/B] |
