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.

sqlplsu /as sysdba

SQL> show parameter db_recovery

NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
db_recovery_file_dest                string      e:\oracle\product\10.2.0/flash
                                                 _recovery_area
db_recovery_file_dest_size           big integer 2G


1.加大db_recovery_file_dest_size大小
  alter system set db_recovery_file_dest_size=3G scope=both;
  然后重新启动数据库即可。
2.重新指定文件的存储位置
3.删除多余的文件(我采用的便是这种办法)

  第一步：启动rman
  c:\>rman target /
  第二步：检查归档日志文件
  RMAN>crosscheck archivelog all;
  第三步：删除文件
  RMAN> delete expired archivelog all;
  .....
然后重新启动数据库alter database open
