手工rm删除归档日志对备份归档日志的影响

手工rm删除归档日志后，备份归档日志的时候会报错找不到删除的归档日志，crosscheck archivelog all和delete expired archivelog all后，备份归档日志不再报错 使用rman的delete命令删除归档日志后，备份归档日志不会报错 [oracle@oatest 2018_07_26]$ ll 总用量 12720 -rw-r-----. 1 oracle dba 12994048 7月  26 11:27 o1_mf_1_494_folhwg5h_.arc -rw-r-----. 1 oracle dba     1536 7月  26 11:27 o1_mf_1_495_folhwhdx_.arc -rw-r-----. 1 oracle dba     2560 7月  26 11:27 o1_mf_1_496_folhwkfj_.arc -rw-r-----. 1 oracle dba     1024 7月  26 11:27 o1_mf_1_497_folhwlbh_.arc -rw-r-----. 1 oracle dba     1024 7月  26 11:27 o1_mf_1_498_folhwq9c_.arc -rw-r-----. 1 oracle dba     1024 7月  26 11:27 o1_mf_1_499_folhwr3b_.arc -rw-r-----. 1 oracle dba     1024 7月  26 11:27 o1_mf_1_500_folhwx96_.arc -rw-r-----. 1 oracle dba     1024 7月  26 11:27 o1_mf_1_501_folhwy86_.arc [oracle@oatest 2018_07_26]$ rm -f o1_mf_1_ 496 _folhwkfj_.arc o1_mf_1_ 497 _folhwlbh_.arc o1_mf_1_ 498 _folhwq9c_.arc RMAN>  backup archivelog all format '/home/oracle/archivelog%U' delete input; Starting backup at 26-JUL-18 current log archived using target database control file instead of recovery catalog allocated channel: ORA_DISK_1 channel ORA_DISK_1: SID=224 device type=DISK RMAN-00571: =========================================================== RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS =============== RMAN-00571: =========================================================== RMAN-03002: failure of backup command at 07/26/2018 11:31:23 RMAN-06059: expected archived log not found, loss of archived log compromises recoverability ORA-19625: error identifying file /u01/app/oracle/fast_recovery_area/PROD7/archivelog/2018_07_26/o1_mf_1_496_folhwkfj_.arc ORA-27037: unable to obtain file status Linux-x86_64 Error: 2: No such file or directory Additional information: 3 RMAN> crosscheck archivelog all; RMAN> delete expired archivelog all; ...
