cnhtm發表於2009-12-01

資料庫rman restore database 之後，執行recover database的時候，報告ORA-01245錯誤，詳細的錯誤資訊如下：

檢查ORA-01245那一行，發現是datafile 2狀態為offline，解決的方法就是首先將datafile 2 online，然後再recover database。

SQL> alter database datafile 2 online;

Database altered.

SQL> recover database until cancel;
ORA-00279: change 575876 generated at 12/01/2009 08:19:49 needed for thread 1

Specify log: {=suggested | filename | AUTO | CANCEL}
