閃回恢複區大小不夠。報ORA-19809、ORA-19804

問題： 閃回恢複區大小不夠，rman預設備份路徑報錯。

原因：閃回恢複區大小不夠

oracle10g,11g在預設情況下，歸檔日志是儲存在閃回恢複區的，如果你建庫的時候用的預設設定，

閃回恢複區應該是2G，空間不夠，沒辦備份。（同理歸檔日志儲存也可能碰到這個問題，導緻無法再歸檔）

解決：

（1）調整添加閃回區大小

（2）将備份的目錄換成其他路徑。

     如果是歸檔報錯，即将歸檔目錄設定到其他目錄，修改alter system set log_archive_dest = 其他路徑 

步驟：

1、檢視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

2、 檢視閃回恢複區使用情況

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

3、 擴充db_recovery_file_dest 大小

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

System altered.

4、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
