檢視alter_yms.log

 Errors in file e:\app\administrator\diag\rdbms\yms\yms\trace\yms_m000_3812.trc:

************************************************************************
You have following choices to free up space from recovery area:
1. Consider changing RMAN RETENTION POLICY. If you are using Data Guard,
   then consider changing RMAN ARCHIVELOG DELETION POLICY.
2. Back up files to tertiary device such as tape using RMAN
   BACKUP RECOVERY AREA command.
3. Add disk space and increase db_recovery_file_dest_size parameter to
   reflect the new space.
4. Delete unnecessary files using RMAN DELETE command. If an operating
   system command was used to delete files, then use RMAN CROSSCHECK and
   DELETE EXPIRED commands.

顯示恢復區域不足：

1.停止歸檔.

  startup mount

 alter database noarchivelog;

2. 檢視歸檔引數資訊：

 archive  log list

 資料庫日誌模式            存檔模式
自動存檔             啟用
存檔終點            E:\app\Administrator\oradata\archive
最早的聯機日誌序列     11
下一個存檔日誌序列   13
當前日誌序列           13

3.檢查刪除歸檔內容：

CROSSCHECK BACKUPSET;
DELETE NOPROMPT OBSOLETE;
crosscheck archivelog all;
DELETE NOPROMPT OBSOLETE;

4.更改歸檔路徑：

alter system set log_archive_dest_1='location=E:\app\Administrator\oradata\archive
' scope=spfile sid='*';

5.重啟資料庫。
