Oracle RMAN 丢失归档日志：ORA-19625: error identifying file


在CentOS 5.6 x64 平台备份时出现错误：

RMAN> backup archivelog all format='/opt/Oracle/backup/arch_%T_%s_%p.bak';

Starting backup at 31-AUG-11
using target database control file instead of recovery catalog
allocated channel: ORA_DISK_1
channel ORA_DISK_1: SID=11 device type=DISK
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03002: failure of backup command at 08/31/2011 23:52:25
RMAN-06059: expected archived log not found, loss of archived log compromises recoverability
ORA-19625: error identifying file /data/oracle/fast_recovery_area/DB1/archivelog/2011_08_30/o1_mf_1_5_75t010tk_.arc
ORA-27037: unable to obtain file status
Linux-x86_64 Error: 2: No such file or directory
Additional information: 3

这时要进行交叉检测：

RMAN> change archivelog all crosscheck;

released channel: ORA_DISK_1
allocated channel: ORA_DISK_1
channel ORA_DISK_1: SID=11 device type=DISK
