I wonder why dbms_adr/dbms_adr_app, and even dbms_system.ksdwrt, are not documented. It would be useful for developers to have access to them in rare, exceptional situations. #oracle #documentation #alertlog

If you're doing these things, please stop, or maybe consider a career change: 1) posting the same question in multiple internal Slack/Teams/Whatever spaces 2) saying "it does not work," with no details 3) sharing pictures of code 4) preceding 1-3 with 'Hi' and nothing else
