Hi Folks,
When i see TNS messages entries in my listener log like these how can i determine who or what is causing them and where  they are coming from ?
What do I need to turn on to get more info ?


TNS-12502: TNS:listener received no CONNECT_DATA from client
TNS-01169: The listener has not recognized the password
TNS-01189: The listener could not authenticate the user

Thanks
Jim
