緣由：閃回恢復區大小不夠

oracle10g,11g在默認狀況下，歸檔日誌是保存在閃回恢復區的，若是你建庫的時候用的默認設置，

閃回恢復區應該是2G，空間不夠，沒辦備份。（同理歸檔日誌保存也可能碰到這個問題，致使沒法再歸檔）

解決：

（1）調整添加閃回區大小

（2）將備份的目錄換成其餘路徑。

若是是歸檔報錯，即將歸檔目錄設置到其餘目錄，修改alter system set log_archive_dest = 其餘路徑

步驟：

一、查看db_recovery_file_dest 大小

SQL> show parameter recover

NAME TYPE VALUE

------------------------------------ ----------- ------------------------------

db_recovery_file_dest string/home/oracle/app/flash_recover

y_area

db_recovery_file_dest_size big integer 2G

recovery_parallelism integer0

二、 查看閃回恢復區使用狀況

SQL> select file_type, percent_space_used as used,percent_space_reclaimable as reclaimable, number_of_files as "number" from v$flash_recovery_area_usage;

FILE_TYPE USED RECLAIMABLE number

-------------------- ---------- ----------- ----------

CONTROL FILE 0 0 0

REDO LOG 0 0 0

ARCHIVED LOG 46.76 0 23

BACKUP PIECE .46 0 1

IMAGE COPY 0 0 0

FLASHBACK LOG 0 0 0

三、 擴展db_recovery_file_dest 大小

SQL> alter system set db_recovery_file_dest_size=10G scope=both;

System altered.

四、利用run批腳本指定備份路徑來備份 （建議歸檔與備份分開放置）

run{

allocate channel ch1 type disk;

allocate channel ch2 type disk;

backup incremental level 0 database plus archivelog delete input

format '/home/oracle/rmanbak/db_%d_%U'

tag=db_inc_0;

release channel ch1;

release channel ch2;

}

allocated channel: ch1

。。。。。。

released channel: ch1

released channel: ch2
