Listener Password Deprecated in Oracle 11g Release 2 :
Remember setting the password for listener? Up to just prior to Oracle Database 10g, setting this password was a must for any security establishment worth its salt. In 10g, the password was not mandatory. It was not needed (and was ignored, if set) for the Oracle software owner. It was still possible to set the password for any user other than the Oracle software owner.
LSNRCTL> set password
Password: <Give your desired Password>
The command completed successfully
However, there is little or no need for any other user to start the listener. It’s most likely the Oracle user. Therefore the need for the password is less. In Oracle 11g Release 2 , the password on listener is deprecated.
