把归档日志的物理文件删除后，我们就可以正常登入ORACLE了，但是还没完全把归档日志删除干净，ORACLE的controlfile中仍然记录着这些archivelog的信息，在oracle的OEM管理器中有可视化的日志展现出，当我们手工清除archive目录下的文件后，这些记录并没有被我们从controlfile中清除掉，接下去我们要做的就是这个工作。
我们利用RMAN进行删除操作，

两种方式：

1、先查看使用率，再删除物理文件，再用rman删除。
SQL> select * from V$FLASH_RECOVERY_AREA_USAGE;
[oracle@stdg archivelog]$ pwd
/u01/app/oracle/fast_recovery_area/STDGGT/archivelog
[oracle@stdg archivelog]$ rm -rf 2016_11_22
[oracle@stdg archivelog]$ rman target /
RMAN> list archivelog all;
RMAN> DELETE ARCHIVELOG ALL COMPLETED BEFORE 'SYSDATE-6';
上面直接不能删除，需要先用下面的命令，然后才能删除。
RMAN>　crosscheck archivelog all;
RMAN> delete expired archivelog all;
SQL> select * from V$FLASH_RECOVERY_AREA_USAGE;
用上面的sql查看文件数量与容量大小相应的减少了。

2、先查看使用率，直接用rman删除。
SQL> select * from V$FLASH_RECOVERY_AREA_USAGE;
[oracle@stdg archivelog]$ pwd
/u01/app/oracle/fast_recovery_area/STDGGT/archivelog
[oracle@stdg archivelog]$ rman target /
RMAN> list archivelog all;
RMAN> delete archivelog until time 'sysdate-5';
RMAN> DELETE ARCHIVELOG ALL COMPLETED BEFORE 'SYSDATE-6';
SQL> select * from V$FLASH_RECOVERY_AREA_USAGE;

SYSDATE-7，表明当前的系统时间7天前，before关键字表示在7天前的归档日志，如果使用了闪回功能，也会删除闪回的数据。
同样道理，也可以删除从7天前到现在的全部日志，不过这个命令要考虑清楚，做完这个删除，最好马上进行全备份数据库
DELETE ARCHIVELOG from TIME 'SYSDATE-7'; 删除从7天前到现在的全部日志,慎用
UNIX/LINUX下也可以通过FIND找到7天前的归档数据，使用EXEC子操作删除
find /oraarchive -xdev -mtime +7 -name "*.dbf" -exec rm -f {} ;
这样做仍然会在RMAN里留下未管理的归档文件
仍需要在RMAN里执行下面2条命令
crosscheck archivelog all;
delete expired archivelog all;
所以还不如上面的方法好用，不过用FIND的好处就是，可以在条件上，和EXEC子项上做很多操作，实现更复杂的功能
