lsnrctl中设置口令
步骤如下：
在cmd中设置 Set oracle_sid=test;
进入lsnrctl
步骤1： 命令 change_password 后输入旧口令（无），新口令 pass
步骤2： 命令 save_config
步骤3： 测试stop 直接就stop了
后又步骤一，步骤二，退出lsnrctl，再进，仍然可以直接stop
----------------------------------------------------------------------------------------------------
你可以用status 《listener_name》查看，应该会看到：
Security ON: Password or Local OS Authentication
这样就代表设置password成功了。你能stop仅仅是因为通过了Local OS Authentication。
你可以通过在远程另一台host上设置相同的listener到listener.ora里，然后status或者stop，就会出现这样的提示信息了：
LSNRCTL> set current_listener LISTENER_xxx
Current Listener is LISTENER_xxx
LSNRCTL> status

LSNRCTL> set password 111
The command completed successfully

In Oracle 10, the TNSListener is secure out of the box and there should not be a need to set a listener password as in older versions of the Oracle listener.
Oracle10g以后，设置Listener密码已经不是安全检查的必要条件了，因为默认在10g里面除了启动监听的用户之外，其它用户都无法停止Listener（还有另外一些lsnrctl的命令也同样被禁止了，比如trace, reload等），即使Listener没有设置密码。
在默认情况下，启动Listener或者使用lsnrctl status命令查看监听状态，可以看到：
Security ON: Password OR LOCAL OS Authentication
这表明Listener的安全机制使用了Password方式或者Local OS Authentication方式，在这种状态下，即使是设置了监听密码，对于启动监听的user来说，也仍然是不需要任何密码就可以停止监听的。
如果我们想去除自Oracle10g之后的这种新安全机制，那么需要在listener.ora文件中添加：
LOCAL_OS_AUTHENTICATION_[listener name] = OFF
重新启动Listener之后，将会只看到：
Security ON: Password
这就又回复到了Oracle9i时的状态，只要有密码存在，无论是谁尝试停止监听都会被要求set password。
