listener admin_restrictions violations

I have a server with admin_restrictions violations informed by my team lead. How do we check the violations and resolve it. I really appreciate your help. Thanks in advance

note a full listener restart (stop/start) isn't really needed.  
you can simply reload too to do it on the fly

I believe these should be logged in the listener.log.  Check that for messages about the violations.
if you have admin_restrictions turned on then nobody can modify the listener directly,  there is nothing to resolve unless you've found a bug where somebody could alter the listener even with restrictions turned on.  If that's the case then contact oracle support immediately.

if the problem is you have admin_restrictions on and you need to change something, then edit the listener.ora file and restart the listener

if securing your listener isn't important then edit the listener.ora to turn admin_restrictions off and restart

- i believe the listener have been set with ADMIN_RESTRICTIONS_LISTENER=ON. therefore the violation is related to attempted changes to parameters in the listener.ora through set commands.

Can I ask why you selected the answer you did on this question?
The question asked was:  How do we check the violations and resolve it.

The selected answer was a link to the docs on how to set the listener.ora parameter to turn restrictions on and off.

If turning it on and off was what you were after then the post above should be selected and at best an 'assist' for the actual doc link.

Please clarify.
