远程用户是否能 start listener 有待验证

要是密码丢失了 可以尝试用以下几种方法：
1. Open the listener.ora and find the following line: "filepasswords_listener= " Type "pwd" after the = sign. Stop the listener and restarted it.
1a. Then perform. the following: LSNRCTL> set password pwd command successfully LSNRCTL> stop command successfully

2. If the previous step does not work, try commenting out the following line on the listener.ora file: #passwords_listener= xxxx
2a. Stop the listener process. Restart and stop listener again.

3. Verify that the passwords_listener parameter has a value - it cannot be set to a blank password.
