今天在做rman 删除过期备份的文件。命令如下：
RMAN> allocate channel for maintenance type disk ;
allocated channel: ORA_MAINT_DISK_1
channel ORA_MAINT_DISK_1: sid=382 instance=socl1 devtype=DISK
RMAN> crosscheck backup ;
crosschecked backup piece: found to be 'EXPIRED'
backup piece handle=/backup/2dld3018_77_1_05 recid=76 stamp=718372910
crosschecked backup piece: found to be 'EXPIRED'
backup piece handle=/backup/2eld303o_78_1_05 recid=77 stamp=718372985
crosschecked backup piece: found to be 'EXPIRED'
。。。。。
RMAN> delete expired backup ;
