rman中如何制定删除某段时间的归档日志eg：
rman> sql 'alter session set nls_date_format=yyyy-mm-dd';
sql statement: alter session set nls_date_format=yyyy-mm-dd
rman> delete archivelog from time 2012-12-01 until time 2013-02-28;
released channel: ora_disk_1
allocated channel: ora_disk_1
channel ora_disk_1: sid=144 devtype=disk
specification does not match any archive log in the recovery catalog
小结：
sql 'alter session set nls_date_format=yyyy-mm-dd';
delete archivelog from time 2012-12-01 until time 2013-02-28;
