oracle删除归档,可以使用rman删除归档,也可以使用rm直接删除!

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';
