问题7----重做日志文件一直切换不到非活动状态

问题解决了，我关掉数据库出去了，然后回来一看就可以了，难道是要重启一下吗？

SQL> conn sys/ as sysdba
输入口令: ****
已连接。
SQL> select group#,sequence#,members,status,bytes,archived from v$log;

GROUP# SEQUENCE# MEMBERS STATUS BYTES ARC
---------- ---------- ---------- ---------------- ---------- ---
1 9 1 INACTIVE 52428800 NO
2 10 3 CURRENT 15728640 NO
3 7 3 INACTIVE 15728640 NO
4 8 3 INACTIVE 15728640 NO

SQL> alter database drop logfile group 1;

数据库已更改。

心情不好，不纠结这么多，哪天再弄吧
