rman备份archivelog时出现以下错误： RMAN> backup archivelog all delete input; Starting backup at 14-APR-14 current log archived using channel ORA_DISK_1 using channel ORA_DISK_2 RMAN-00571: =========================================================== RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS =============== RMAN-00571:

网上查了出错原因是由于操作系统下删除了这个归档日志，这个日志还没备份过，rman去备份的时候，找不到这个归档就出错了。可使用change archivelog all crosscheck命令来解决此问题，如下： RMAN> change archivelog all crosscheck; 这个命令其实就是 crosscheck archivelog all; released channel:
