很奇怪的問題!!! ORA-00317 file type 0 in header is not log file

ALLSTARS_ORACLE

今天,recover standby DB的時候,出現了錯誤:

SVRMGR> recover database using backup controlfile until cancel;
ORA-00279: change 13306060931 generated at 10/30/2005 16:12:29 needed for threa1
ORA-00289: suggestion : /oradata/oradata4/ctofa/archive/1_18785.dbf
ORA-00280: change 13306060931 for thread 1 is in sequence #18785
Specify log: {<RET>=suggested | filename | AUTO | CANCEL}

ORA-00317: file type 0 in header is not log file
ORA-00334: archived log: '/oradata/oradata4/ctofa/archive/1_18785.dbf'

但是這個archive file是存在的,而且之前一直都是可以recover的 .
我後來檢查了product 和 spare DB的alert.ora .

Product DB 沒有任何錯誤

Standby DB 的錯誤如下:

Sun Oct 30 16:20:01 2005
ALTER DATABASE RECOVER    CONTINUE DEFAULT

不知道為什麼?
沒有辦法的話,只好重做了喔.
