如果查询v$log的online redo log是inactive, 明日志是非前日志, 而且已完成 ( STATUS 是INACTIVE , ARCHIVE 是YES ) .

理方法(用於及非) :

使用clear 命令清理文件所在的redo log group .

SQL> alter database clear logfile group 3 ;

如果日志有 (STATUS 是INACTIVE , ARCHIVE 是 NO )

那需要使用如下命令

SQL> alter database clear unarchived logfile group 3 ;

然後打 , 份 .
