ORA-02396: exceeded maximum idle time, please connect again

0
insert into agent_task(TASK_ID,TYPE,CREATED_TIME,RELATION_OBJECT_ID) values(TASK_ID.nextval,1,sysdate,7364794)

如果dba修改了dba_profile中的idle_time默认值,将会对连接进行一定的限制

但有时却很莫名地错，有很多进程的状态是inactive，却不正常退出,解决

办法是取消该限制一段时间，然后再限制就可以解决一些问题，从metalink

上查,这是一个8i的bug，为什么在9.2.0.4中还有呢？

sql>alter profile default limit idle_time unlimited;

等待一会

sql>alter profile default limit idle_time 16;

SQL> select * from dba_profiles;

SQL> select * from dba_profiles;
