Deprecation of Listener Password in Oracle 11g

強烈反對配置數據庫監聽密碼在Oracle 11g及以后版本中，強制使用本地操作系統認證（LOSA）

上峰來檢查也應該更新一下檢查文檔了，官方已經強烈反對了，你還要檢查是否設置密碼是不是不太對啊！！！！！！！！！

官方說明如下：

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.
