SQL> conn  admin/admin

检查空间：
SQL> select name, total_mb, free_mb from v$asm_diskgroup;

NAME                             TOTAL_MB    FREE_MB
------------------------------ ---------- ----------
ARCH                               327680        176
DATA                               737280      10941
OCRBAK                              30720      29794

SQL> select name,total_mb,free_mb from v$asm_disk;
如果用到recover_area_usage，那么检查select * from V$FLASH_RECOVERY_AREA_USAGE; 
处理方法：
 

asmcmd
cd +ARCH/jxdb/archivelog/
rm -rf 2014_10_*

rman target /

crosscheck archivelog all;
delete noprompt expired archivelog all;

或者：（本次使用下面方法）
delete noprompt force archivelog all completed before 'sysdate-7'; 

强制删除全部的话：

delete noprompt force archivelog all;
