一、使用以下的命令清理了空间：
| 1 2 | 1. cd /orabak 2. find . - type f -mtime +30 - exec rm -rf {} \; |
二、然后开始使用rman备份的脚本进行备份，备份到最后出现以下报错
| 1 2 3 4 5 6 7 8 9 10 11 | ------------------------------------------------------------------------------------------- archive log filename= /oralog/1_20800_812554797 .dbf recid=20799 stamp=839154512 archive log filename= /oralog/1_20801_812554797 .dbf recid=20800 stamp=839154513 released channel: ch1 RMAN-00571: =========================================================== RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS =============== RMAN-00571: =========================================================== RMAN-03009: failure of backup command on ch1 channel at 02 /10/2014 10:33:46 ORA-19571: archived-log recid 19009 stamp 837863118 not found in control file ------------------------------------------------------------------------------------------- |
三、分析及处理过程
1、当手工删除了归档日志以后，Rman备份会检测到日志缺失，从而无法进一步继续执行。
所以此时需要手工执行crosscheck过程，之后Rman备份可以恢复正常。
2、Crosscheck日志
| 1 2 3 | $ rman target / RMAN> crosscheck archivelog all; #Oracle 9i及以后的版本用crosscheck archivelog all; RMAN> change archivelog all crosscheck; #Oracle 8i中用change archivelog all crosscheck; |
3、再次运行备份脚本
| 1 2 3 4 5 6 7 | -- archive log filename= /oralog/1_20887_812554797 .dbf recid=20886 stamp=839198925 archive log filename= /oralog/1_20888_812554797 .dbf recid=20887 stamp=839198982 archive log filename= /oralog/1_20889_812554797 .dbf recid=20888 stamp=839199982 archive log filename= /oralog/1_20890_812554797 .dbf recid=20889 stamp=839199982 Finished backup at 10-FEB-14 Starting backup at 10-FEB-14 channel ch1: starting full datafile backupset channel ch1: specifying datafile(s) in backupset including current control file in backupset channel ch1: starting piece 1 at 10-FEB-14 channel ch1: finished piece 1 at 10-FEB-14 piece handle= /orabak/control_11839200079688 tag=TAG20140210T230759 comment=NONE channel ch1: backup set complete, elapsed time : 00:00:01 Finished backup at 10-FEB-14 released channel: ch1 -- 完成 |
