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。
