133.You created a profile APP_USER and assigned it to the users. After a month, you decide to drop the
profile. Some user sessions are currently connected to the database instance and are using the
APP_USER profile.
This command is used to drop the profile:
SQL> DROP PROFILE app_user;
Which statement describes the result?
A. The command produces an error.
B. The profile is dropped and current user sessions use the DEFAULT profile immediately.
C. The profile is dropped and only the subsequent user sessions use the DEFAULT profile.
D. The profile is dropped, the sessions are terminated, and the subsequent user sessions use the
DEFAULT profile.
Answer: A
【解析】
CREATE PROFILE profile1 LIMIT;
ALTER USER scott PROFILE profile1;
--此时查看用户SCOTT的default profile变为：profile1
SYS@orcl> drop profile profile1;
drop profile profile1
*
第 1 行出现错误:
ORA-02382: 概要文件 PROFILE1 指定了用户, 不能没有 CASCADE 而删除
SYS@orcl> drop profile profile1 cascade;
配置文件已删除。
--profile1删除后，scott的default profile自己主动变回default
答案一目了然！
