While logging in using the Enterprise manager, I see 4 violations in the listener in the database.
1) Listener.ora permission (WIndows)
2) Listener direct administration
3) Litener Logfile permission )WIndows)
4) restrict sqlnet.ora permission (windows)
I checked the permissions for the listener and sqlnet.ora files It had 4 groups ( system, administrator, authenticated users and oracel user)
tried to change teh permission for authenticated users by denying them the permisions as per the document Listener Policies but still facing the same violation alert,
thanks, in advance
