ORA-19809: limit exceeded for recovery files
ORA-19804: cannot reclaim 52428800 bytes disk space from 2147483648 limit

原因：flash_recovery_area空间不足

检查flash_recovery_area使用情况
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
------------------------ ---------- ----------- ----------
CONTROLFILE                     .33           0          1
ONLINELOG                      7.32           0          3
ARCHIVELOG                        0           0          0
BACKUPPIECE                    1.05           0          2
IMAGECOPY                         0           0          0
FLASHBACKLOG                      0           0          0
6 rows selected.

检查db_recovery_file_dest_size参数
SQL> show parameter db_recovery_file_dest_size

NAME                                 TYPE                   VALUE
------------------------------------ ---------------------- ------------------------------
db_recovery_file_dest_size           big integer            2G（默认）

将参数db_recovery_file_dest_size增大为10G
SQL> alter system set db_recovery_file_dest_size=10G scope=both;
System altered.

再次备份，成功
