1、使用rm删除归档：删除所有归档：find /u01/app/oracle/archive -mt坡纠课柩ime -1 -na罪焐芡拂me "*.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';
