Oracle standby庫的ORA-01274問題

在standby數據庫中，初始化參數STANDBY_FILE_MANAGEMENT設置爲MANUAL環境中，當主庫新建一個數據文件時，它MRP進程中止，後臺介質恢復工作失敗。這是因爲standby數據庫不能自動創建新文件，參數配置決定了。

在alert.log中，日誌信息如下：

Thu Apr 11 16:44:37 2013
Primary database is in MAXIMUM PERFORMANCE mode

MRP0: Background Media Recovery process shutdown (lbesup)

解決方法很簡單，很簡單。

SQL> alter database create datafile '/u01/app/oracle/product/10.2.0/db/dbs/UNNAMED00012' as '+VG1/lbesup/lb_7881_data01.dbf';

Database altered.

然後啓用恢復進程，問題解決。
