简介:   Examine these attributes for the profile assigned to USER1 whose password is oracle_4U.  • PASSWORD_REUSE_MAX is 5.

  Examine these attributes for the profile assigned to USER1 whose password is oracle_4U.

  • PASSWORD_REUSE_MAX is 5.

  • PASSWORD_REUSE_TIME is 10.

  • PASSWORD_GRACE_TIME is 15.

  Which two conditions must be met for USER1 to reuse oracle_4U?

  A)At least 5 days must have passed since oracle_4U was last used.

  B)The password must have changed 5 times since oracle_4U was last used.

  C)At least 10 days must have passed since oracle_4U was last used.

  D)The password must have changed 10 times since oracle_4U was last used.

  E)At least 15 days must have passed since oracle_4U was last used.

  Answer: BC

  赵:

  B 译:自上次使用 Oracle_4U 以来,密码必须更改了 5 次。

  C 译:自最后一次使用 oracle_4U 以来,至少已经过去了 10 天。

  MAX 是次数,TIME 是天数。

  password_reuse_time 指定了密码不能重用前的天数

  password_reuse_max 则指定了当前密码被重用之前密码改变的次数

  PASSWORD_REUSE_TIME 和 PASSWORD_REUSE_MAX:这两个参数必须互相关联设置。

  总结两者之间的规律:

  (1)都为 UNLIMITED,密码可以随意重用,没有任何限制。

  (2)均为指定值时,必须满足这两者的条件时才可以重用密码。

  (3)当 PASSWORD_REUSE_MAX,PASSWORD_REUSE_TIME 两个有其中一个不为 UNLIMITED,则密码永远不能重用。

  如果密码过期了并且 PASSWORD_GRACE_TIME 设置为 15 天,那么在 15 天在之内如果不变更密码账号就会被锁定。Grace time 宽限期。
