rman下误删除归档日志的解决方法：

change archivelog all crosscheck;

误删除备份集的解决方法类似：

crosscheck backup;

delete obsolete;

今天在使用rman作备份恢复测试时，删除了数据库的归档日志文件，结果rman备份归档日志的时候报错不能正常进行归档日志的备份工作

报错内容： ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03002: failure of backup command at 08/04/2006 14:23:50

ORA-19625: error identifying file c:oraclelogarc000006.log
ORA-27037: unable to obtain file status
Linux Error: 2: No such file or directory

解决方法：change archivelog all crosscheck;

delete obsolete;
