解决方法：
 查看帐号的信息：
SQL> select USERNAME,ACCOUNT_STATUS,LOCK_DATE,EXPIRY_DATE,password,CREATED from dba_users where username=upper('xxx ');

USERNAME      ACCOUNT_ST LOCK_DATE    EXPIRY_DATE             CREATED
-------------------- ---------- -------------------- ------------------- ------------------------------ -------------------
xxx                 EXPIRED       2013-04-22 14:44:43      2012-10-17 14:20:15

 查看帐号的PASSWORD_LIFE_TIME设置：
SQL> select * from dba_profiles where profile like '%xxx%';
PROFILE               RESOURCE_NAME                    RESOURCE LIMIT
------------------------------ -------------------------------- -------- ----------------------------------------
PF_xxx       PASSWORD_LIFE_TIME               PASSWORD DEFAULT
 查看系统PROFILE文件的默认设置：
SQL> select * from dba_profiles where profile like '%DEFAULT%';
PROFILE          RESOURCE_NAME                    RESOURCE LIMIT
------------------------------ -------------------------------- -------- ----------------------------------------
DEFAULT        PASSWORD_LIFE_TIME               PASSWORD 180
 设置了用户的PASSWORD_LIFE_TIME，默认为180天；
 修改用户的PASSWORD_LIFE_TIME限制：
SQL> alter profile DEFAULT limit PASSWORD_LIFE_TIME unlimited;
Profile altered.
 重新设置用户的密码：
SQL> alter user xxx identified by xxx;
User altered.
SQL> select USERNAME,ACCOUNT_STATUS,LOCK_DATE,EXPIRY_DATE,password,CREATED from dba_users where username=upper('xxx');
USERNAME    ACCOUNT_ST LOCK_DATE     EXPIRY_DATE         CREATED
-------------------- ---------- -------------------- ------------------- ------------------------------ -------------------
XXX               OPEN             2012-10-17 14:20:15
 帐号状态恢复正常。

注意：
因为这个帐号是应用程序在使用的，不能更换密码，所在在使用alter user...identified by的时候，需要使用这个帐号当前的密码进行操作。
