************************************************************************
You have following choices to free up space from flash 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.

--查看当前 recovery_file_dest 使用情况
set lines 200
select substr(name,1,30) name,space_limit as quota,space_used as used,space_reclaimable as reclaimable,number_of_files as files from v$recovery_file_dest;

解决方法一：
--扩大db_recovery_file_dest_size大小
SQL> show parameter recovery

NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
db_recovery_file_dest                string      /opt/oracle/flash_recovery_are
                                                 a
db_recovery_file_dest_size           big integer 2G
recovery_parallelism                 integer     0

解决方法二：
--清理快速恢复区信息

rman 执行:
run {
crosscheck archivelog all;
delete noprompt obsolete;
crosscheck backup;
delete noprompt expired archivelog all;
delete noprompt expired backup;
resync catalog;
}

--查看执行之后 recovery_file_dest 使用情况
