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

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。
