ORACLE 帐户 状态说明

大概的给解释一下open.locked,expired,EXPIRED(GRACE) ,LOCKED(TIMED) ,
其余几个概念就是这几个状态的组合:-)

1. open 当前 用户是开放的可以使用的.
[color=gray]SQL> select username,account_status from dba_users where username = 'TONGJW';

USERNAME                       ACCOUNT_STATUS
------------------------------ --------------------------------
TONGJW                         OPEN

SQL> conn tongjw
Enter password: *******
Connected.
[/color]
2. expired 表示用户已经过期, 登录的时候, 如果密码输入正确,系统会提示重新输入密码的.
[color=gray]
SQL> conn jfdata/jf
Connected.
SQL> alter user tongjw account unlock;

User altered.

SQL> alter user tongjw password expire;

User altered.

SQL> conn tongjw
Enter password: *******
ERROR:
ORA-28001: the password has expired


Changing password for tongjw
New password: *******
Retype new password: *******
Password changed
Connected.
[/color]

3. locked 表明当前帐户被锁了, 不可以登录的.
[color=gray]
SQL> conn jfdata/jf
Connected.
SQL> alter user tongjw account lock;

User altered.

SQL> conn tongjw
Enter password: *******
ERROR:
ORA-28000: the account is locked


Warning: You are no longer connected to ORACLE.
[/color]
expired (grace)  与 locked (timed) 是有 系统的profile来进行控制的.

4. expired (grace) 指定一个期限, 到达这个期限的时候,系统会给出一个警告并且允许登录(grace), 如果过了这段期限, 对应的密码就会自动过期, 相当于我们的密码过期提醒.
PASSWORD_GRACE_TIME
PASSWORD_LIFE_TIME
Specify the number of days after the grace period begins during which a warning is issued and login is allowed. If the password is not changed during the grace period, the password expires.
