You have following choices to free up spacefrom 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 astape using RMAN
BACKUP RECOVERY AREA command.
3. Add disk space and increasedb_recovery_file_dest_size parameter to
reflect the new space.
4. Delete unnecessary files using RMANDELETE command. If an operating
system command was used to delete files, then use RMAN CROSSCHECK and
DELETE EXPIRED commands.

3，查看归档日志
RMAN> crosscheck archivelog all; –先检查下
…
validation succeeded for archived log
archived log filename=/oracle/app/oracle/flash_recovery_area/PDUNQ/archivelog/2015_04_23/o1_mf_1_72_bmkbwfrg_.arcRECID=63633 STAMP=877796493

4，这里采用删除多余的归档日志的办法来操作，查看过期归档日志
[oracle@powerlong4 ~]$ rman target /
RMAN> delete expired archivelog all;
released channel: ORA_DISK_1
allocated channel: ORA_DISK_1
channel ORA_DISK_1: SID=787 devicetype=DISK
specification does not match any archivedlog in the repository
RMAN>
5，删除过期的归档日志
delete expired archivelog all;
RMAN> delete expired archivelog all;
released channel: ORA_DISK_1
allocated channel: ORA_DISK_1
channel ORA_DISK_1: SID=787 devicetype=DISK
specification does not match any archivedlog in the repository
RMAN>
看到没有过期的归档日志
6，看到没有过期的，不够我们可以删除指定到具体的时间，这样也可以腾出空间来
RMAN>delete archivelog until time"to_date(‘2015-04-27 13:00:00′,’yyyy-mm-dd hh24:mi:ss’)";
部分执行过程如下：
RMAN-08137: WARNING: archived log notdeleted, needed for standby or upstream capture process

RMAN>
select * from V$FLASH_RECOVERY_AREA_USAGE;
7，再去查看下使用空间

当明知不可挽回，唯一补偿的方法就是怀念，
