ORA-28001问题的解决.doc

据库运行一直很正常，管理平台之前也可以正常登录。这次要建表空间，结果em上不去，页面提示到实例的代理连接失败出现的图上，显示（1）数据库实例，是红色向下的箭头（2）到数据库的实例链接，是红色向下的箭头，并有错误提示：状态 失败详细资料 ORA-28001: the password has expired (DBD ERROR: OCISessionBegin)（3）监听，绿色向上的箭头如果点启动的话，输入主机密码、sys密码，可以起停数据库。且应用、sqlplus都能连上不过用net服务的测试连接的话，自己设置的用户名可以连上，但是system连不上。很迷惑。于是搜索了很多。和实例链接失败的很多，但是提示密码失效的并不多。还有备份空间过满，等问题。/312079/viewspace-245769这个帖子里，说到了用户被锁定的事，不过贴主的用户是open的，貌似问题没有解决。索性一试。SQL*Plus: Release .0 - Production on 星期四 2月 5 10:48:26 2009Copyright (c) 1982, 2007, Oracle.
