启用密码管理之前创建的用户连接Oracle报ORA-28002处理一则
处理方法其实很简单、只要：
alter user identified by ; 这个操作后，恢复正常了
下面作个简单测试：
SQL> conn hr/hr
ERROR:
ORA-28002: the password will expire within 2 days
Connected.
SQL> conn / as sysdba
Connected.
SQL> alter user hr identified by hr;
User altered.
SQL> conn hr/hr
Connected.
SQL> conn scott/tiger
ERROR:
ORA-28002: the password will expire within 2 days
Connected.
SQL> conn / as sysdba
Connected.
SQL> alter user scott identified by tiger;
User altered.
SQL> conn scott/tiger
Connected.
