Oracle手动删除归档日志厚，出现ORA-19571错误

一、使用以下的命令清理了空间：

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

-------------------------------------------------------------------------------------------
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-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

$ 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

--

5、rman的备份脚本

run{
allocate channel ch1 device type DISK;
backup full filesperset 50
database format'/orabak/full_%c_%p_%t_5s';
sql 'alter system archive log current';
backup  filesperset 50 archivelog all
format '/orabak/arch%c%p%t%s' delete input;
backup current controlfile
format  '/orabak/control_%c%p%t%s';
release channel ch1;
}
