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';
