Deprecation of Listener Password in Oracle 11g

强烈反对配置数据库监听密码在Oracle 11g及以后版本中，强制使用本地操作系统认证（LOSA）

上峰来检查也应该更新一下检查文档了，官方已经强烈反对了，你还要检查是否设置密码是不是不太对啊！！！！！！！！！

官方说明如下：

APPLIES TO:
Oracle Net Services - Version 11.2.0.1 to 12.2.0.1 [Release 11.2 to 12.2]
Information in this document applies to any platform.
DETAILS
In Oracle Database 11g Release 2 (11.2), the listener password feature is being deprecated. 
This does not cause a loss of security because authentication is enforced through local operating system authentication or LOSA.

ACTIONS
When upgrading to Oracle Database 11g Release 2 (Patch Set 11.2.0.3 and later) , follow the steps below to migrate a listener that has a set password: 

1. Remove all PASSWORDS_listener_name entries from the listener.ora file. 
2. Reload the listener using the following command: lsnrctl reload listener_name 

If remote administration of a listener is required, then use one of the following methods to connect to and administer the listener. 

 Connect to the host where listener is running using SSH or other secure method, and then perform local   administration. Local administration is enforced by the operating system authentication. 
 Use Oracle Enterprise Manager to administer the listener. Oracle Enterprise Manager uses HTTPS,  which ensures security.
Please note, that this feature will be de-supported in the next major Oracle Database version (currently called 12g) and will then no longer be available.
