oracle rman 删除过期备份成功后，下次还要显示这些过期文件

CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 7 DAYS;

执行如下命令：

crosscheck backup;
有很多过期的备份文件显示

RMAN> crosscheck backup;

allocated channel: ORA_DISK_1
channel ORA_DISK_1: sid=2005 devtype=DISK
crosschecked backup piece: found to be 'AVAILABLE'
backup piece handle=/oraback/ARSHD/backup_rman/ARS_L0_20140810_qqpfj98m_1_1 recid=556146 stamp=855221538
crosschecked backup piece: found to be 'AVAILABLE'
backup piece handle=/oraback/ARSHD/backup_rman/ARS_L0_20140810_qrpfj98r_1_1 recid=556147 stamp=855221538
crosschecked backup piece: found to be 'AVAILABLE'
backup piece handle=/oraback/ARSHD/backup_rman/ARS_L0_20140810_qopfj98j_1_1 recid=556148 stamp=855221530



delete noprompt obsolete;

删除成功



可下次再执行上面的命令的时候，那些过期文件还会显示，而显示的这些文件早就手工从OS层面删除。
