rman删除归档日志

删除日志:

 1.用RMAN连接目标DB:

  RMAN target sys/*****@orcl

  2.在RMAN命令窗口中,输入如下命令:

  crosscheck archivelog all;

  delete expired archivelog all;

  或者删除指定时间之前的archivelog:

  DELETE ARCHIVELOG ALL COMPLETED BEFORE 'SYSDATE-7';(指定删除7天前的归档日志)

  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;
    查看过期备份
    RMAN> report obsolete; 
    删除过期备份
    RMAN> delete obsolete;


  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;

   5.
   DELETE ARCHIVELOG ALL COMPLETED BEFORE 'SYSDATE-7'; //删除七天前的归档
   DELETE ARCHIVELOG FROM TIME 'SYSDATE-7'; //删除七天到现在的归档
