Yes indeed thanks.
Some procedure like below
CREATE OR REPLACE PROCEDURE kill_session_sp
          pn_sid IN number
        , pn_serial IN number)
AS
lv_user varchar2(30);
BEGIN
  SELECT username INTO lv_user FROM v$session WHERE sid = pn_sid AND serial# = pn_serial;
IF lv_user IS NOT NULL AND
    lv_user NOT IN  ('SYS','SYSTEM') AND
    lv_user NOT IN (SELECT user_name from privileged_users)  -- stop users kiiling System and DBA accounts
THEN
  EXECUTE IMMEDIATE 'ALTER SYSTEM KILL SESSION '''||pn_sid||','||pn_serial||'''';
ELSE
  RAISE_APPLICATION_ERROR(-20099,'Attempt to kill protected system session has been blocked for user '||lv_user);
END IF;
END kill_session_sp;Obviously a grant execute on that procedure should be given to someone. Normally only DBAs and production sypport may have that level of access
Why is Oracle not record the kill processes in alert log?
Cheers,
Mich
