oracle删除归档

1、使用rm删除归档：

删除所有归档：find /u01/app/oracle/archive -mtime -1 -name "*.dbf" -exec rm -f {} \;或find /u01/app/oracle/archive -mtime -1 -name "*.dbf"| xargs rm -rf

删除七天前的归档：find /u01/app/oracle/archive -mtime +7 -name "*.dbf" -exec rm -f {} \;或find /u01/app/oracle/archive -mtime +7 -name "*.dbf"| xargs rm -rf

最后需要用rman删除记录：

rman target /crosscheck archivelog all;delete noprompt expired archivelog all;

2、根据sequence#使用rman删除归档：

单节点：

delete noprompt archivelog until sequence ${Seq};

rac（thread后面加节点数）:

delete noprompt archivelog until sequence ${Seq} thread ${CurThread};

删除7天前的归档：

DELETE ARCHIVELOG ALL COMPLETED BEFORE 'SYSDATE-7';

删除全部归档（noprompt不交互）：

DELETE noprompt ARCHIVELOG ALL COMPLETED BEFORE 'SYSDATE-0';

删除从7天前到现在的全部日志：

DELETE ARCHIVELOG FROM TIME 'SYSDATE-7';

3、根据时间使用rman删除归档：

删除7天前的归档：

DELETE ARCHIVELOG ALL COMPLETED BEFORE 'SYSDATE-7';

删除全部归档（noprompt不交互）：

DELETE noprompt ARCHIVELOG ALL COMPLETED BEFORE 'SYSDATE-0';

删除从7天前到现在的全部日志：

DELETE ARCHIVELOG FROM TIME 'SYSDATE-7';
