故障原因
Oracle 11G 普通使用者有個180天的預設密碼周期，當快到期的時候即會出現此提示；

解決辦法
查看目前使用者對應profile、對應密碼周期
select * from dba_profiles where profile='DEFAULT' AND resource_name='PASSWORD_LIFE_TIME';
alter profile default limit password_life_time unlimited;
SELECT username,PROFILE FROM dba_users where username like upper('&USER');
sys@SUN> SELECT username,PROFILE FROM dba_users where username like upper('&USER');
Enter value for user: wang
old 1: SELECT username,PROFILE FROM dba_users where username like upper('&USER')
new 1: SELECT username,PROFILE FROM dba_users where username like upper('wang')
USERNAME PROFILE
------------------------------ ------------------------------
WANG DEFAULT
