95. You want your listener to be password protected to prevent it fro
m being shut down. You want to accomplish this task while the listene
r is functional. Which method could you use to achieve this objective
?
A. Use the CHANGE_PASSWORD command of the Listener control utility.
B. Use the SET PASSWORD and SAVE_CONFIG commands of the Listener cont
rol utility.
C. Use the CHANGE_PASSWORD and SAVE_CONFIG commands of the Listener c
ontrol utility.
D. Manually modify the listener.ora file to include the password for
the listener and restart the listener.
Answer: C
要设置监听器密码只能使用CHANGE_PASSWORD ,而SET PASSWORD 的作用是
密码验证用的，如你设置好了密码后，如果要停止监听，则需要先用SET PASSWORD
输入正确的密码。
如果为listener 设置了口令，那么在lsnrctl 中执行stop，save_config，
change_password 命令操作不论是local 还是remote listener 时都需要通过set
password 来输入口令，只有口令正确才能执行上述命令。
