在我的測試環境中使用rman備份資料庫的時候，報如下錯誤（紅色部分）：

Recovery Manager complete.

這是flash_recovery_area空間不足的提示

[@more@]

用如下方法檢查flash_recovery_area使用情況

oracle@oracle[/oracle]> sqlplus / as sysdba

Connected to:
Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - Production
With the Partitioning, OLAP and Data Mining options

sys@CNHTM> select * from V$FLASH_RECOVERY_AREA_USAGE;

FILE_TYPE PERCENT_SPACE_USED PERCENT_SPACE_RECLAIMABLE NUMBER_OF_FILES

6 rows selected.

檢查db_recovery_file_dest_size引數

sys@CNHTM> show parameter recovery

NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
db_recovery_file_dest string /oracle/flash_recovery_area
db_recovery_file_dest_size big integer 1G
recovery_parallelism integer 0

將引數db_recovery_file_dest_size增大為20G

sys@CNHTM> alter system set db_recovery_file_dest_size=20G scope=both;

System altered.

sys@CNHTM> exit

再次備份，沒有問題了
