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.-typef-mtime+30-execrm-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

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

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

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

$rmantarget/
RMAN>crosscheckarchivelogall;#Oracle9i及以后的版本用crosscheckarchivelogall;
RMAN>changearchivelogallcrosscheck;#Oracle8i中用changearchivelogallcrosscheck;

3、再次运行备份脚本

5、rman的备份脚本

run{
allocatechannelch1devicetypeDISK;
backupfullfilesperset50
databaseformat'/orabak/full_%c_%p_%t_5s';
sql'altersystemarchivelogcurrent';
backupfilesperset50archivelogall
format'/orabak/arch%c%p%t%s'deleteinput;
backupcurrentcontrolfile
format'/orabak/control_%c%p%t%s';
releasechannelch1;
}
