Goal
This document is intended to clarify that from 11.2 onwards, there is no need to first set any tracing parameters under listener.ora or reload the listener to activate listener tracing with timestamps.
Listener tracing can be enabled dynamically through 'set trc_level' command in lsnrctl utility. Independent if ADR is or not enabled, the trace is created with timestamps.
Limitation
~~~~~~~~
Please note that if the ADMIN_RESTRICTIONS_<listener_name> is set to ON for the Listener, then this cannot be done. This parameter needs to be set to OFF or commented out for Dynamic commands to work.
