RMAN-ERROR因找不到过期和丢失的归档日志而备份失败该怎么办，相信很多没有经验的人对此束手无策，为此本文总结了问题出现的原因和解决方法，通过这篇文章希望你能解决这个问题。

oracle RMAN ERROR

oracle采用rman备份，但是备份过程中报错如下：RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03002: failure of backup plus archivelog command at 05/03/2018 15:30:02
RMAN-06059: expected archived log not found, loss of archived log compromises recoverability
ORA-19625: error identifying file /oracle/archlog/cross/1_40137_869580905.dbf
ORA-27037: unable to obtain file status
Linux-x86_64 Error: 2: No such file or directory
Additional information: 3
备份脚本如下：rman target / log=$BACKUPDIR/$DATA/$LOGFILE << EOF
run{
allocate channel ch00 type disk maxpiecesize=4096M;
allocate channel ch01 type disk maxpiecesize=4096M;
backup as compressed backupset full database format '$BACKUPDIR/$DATA/${ORACLE_SID}_level0_%d_%T_%s_%p' plus archivelog format '$BACKUPDIR/$DATA/${ORACLE_SID}_arc_%d_%T_%s_%p' delete all input;
backup current controlfile format '$BACKUPDIR/$DATA/${ORACLE_SID}_control_%d_%T_%s_%p';
backup spfile format '$BACKUPDIR/$DATA/${ORACLE_SID}_spfile_%d_%T_%s_%p';
release channel ch00;
release channel ch01;
}
exit;
EOF
问题分析：

通过报错信息：expected archived log not found，而备份脚本采用了plus archivelog，
分析找到问题：因为找不到过期的归档日志而备份失败。
