清除归档日志
1.用RMAN连接目标DB:
rman target /
RMAN target sys/*****@orcl
2.在RMAN命令窗口中,输入如下命令(清理所有的归档日志):
crosscheck archivelog all;
delete expired archivelog all;
或者清理指定时间之前的日志(archivelog):
DELETE ARCHIVELOG ALL COMPLETED BEFORE 'SYSDATE-7';(指定删除7天前的归档日志);
或者直接如下:
RMAN target sys/*****@orcl;
DELETE NOPROMPT ARCHIVELOG ALL COMPLETED BEFORE 'SYSDATE-7';
=================================================================
RMAN target sys/*****@orcl
DELETE NOPROMPT ARCHIVELOG UNTIL TIME "TO_DATE('XXXX-XX-XX','YYYY-MM-DD')";
3.其它相关命令:
查看归档日志列表:
list archivelog all;
查看失效的归档日志列表:
list expired archivelog all;
4.定期清除archivelog:
可以将如下代码写成.bat文件,在控制面版的任务计划下添加新的定时任务:
RMAN target sys/*****@orcl
crosscheck archivelog all;
delete expired archivelog all;
