Details:
The Listener Password has been deprecated in Oracle Database 11GR2, which does not result in a loss of security because authentication is implemented through the local operating system authentication method.

Let's go:
When upgrading to Oracle Database 11g Release 2 (Patch Set 11.2.0.3 and later), follow the steps below to migrate a Liste Ner that have 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 are 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, which this feature'll be de-supported in the next major Oracle Database version (currently called 12g) and W Ill then no longer is available.
