删除归档日志
一、查看是否开启归档日志
查看是否开启归档 #sqlplus /nolog SQL>connect / as sysdba; SQL> archive log list; Database log mode Archive Mode Automatic archival Enabled Archive destination /arch Oldest online log sequence 1564 Next log sequence to archive 1566 Current log sequence 1566
二、删除数据库归档文件。

cd /arch执行下面命令删除7天以前的归档日志：find . -xdev -mtime +7 -name "*.dbf" -exec rm -f {} ;等同于DELETE ARCHIVELOG ALL COMPLETED BEFORE 'SYSDATE-7'; |
三、执行rman逻辑上删除过期日志
rman RMAN> connect target / >crosscheck archivelog all; #删除所有超期的归档日志 >delete expired archivelog all; #删除7天以外的日志 >delete archivelog all completed before 'sysdate-7'; >quit
