+ The example here is taken from database server on solaris operation system for an dedicated server process
Abbreviation in this note are as follows,
DCD => Dead Connection Detection

Goal
The goal is check and confirm if DCD functionality or mechanism is
working as expected at the DB server side when you have enabled the
respective sqlnet.expire_time parameter.
That is to track if the timer is getting expired after specified interval and
DCD sending probe packets being written on to the tcp socket corresponding
to connected database server process for the respective client.
Especially, without enabling the client and server network traces or
in the case where the client has gone and session at server side is still present.
