198: You have two listener processes, named L1 and L2. Both the listener

processes are currently

functional. While viewing the listener.ora file on your database server,

you find the following entry:

PASSWORDS_L1 = (1sanfrjp43)

What would be the impact of this setting?

A.The listener process named L1 will disconnect the unauthorized users.

B.The listener process named L1 will be prevented from being started by

unauthorized users.

C.The listener process named L1 will be prevented from being stopped by

unauthorized users.

D.The listener process named L1 will be prevented from being reloaded by

unauthorized users.

E.The listener process named L1 will be prevented from accepting

connections from unauthorized users.

Answer: C

lsnrctl>stop listener_r (9i可以直接停掉的)

10g做了设置,停不掉了需要在server端 listener.ora加一个参数,去掉操作系

统验证，让口令生效

但如果10g监听设置了密码就需要密码才能停了
