Kill all sessions of a special user

Question

Hi all,
I'm not very familar with PL/SQL but I think this will help my on my "issue".
Sometimes I need to kill all current sessions (most times 36 sessions) of a single database user.
All sessions have a different sid and serial# and manually executing "alter system kill session 'xxx,yyyy' isn't really funny.
Im thinking of a small PL/SQL script which receives the dbuser name as parameter and then killing all sessions of the user.
Could please anyone give ma a hint or a short example on this??
Many Thanks
Joerg

Hey Hoek,
thanks...
granting "alter system" to my user, by my self :D, let the procedure run without any errors...
Strange thing and good to know...
Ok, but now I'm still having the issue when using the "username" as parameter of the procedure.
create or replace procedure kill_session(user in varchar2)
is
begin
for sessions in ( select sid, serial#
                    from   v$session
                    where  username = 'user_to_kill')
  loop
    execute immediate 'alter system kill session '''||sessions.sid||','||sessions.serial#||'''';
  end loop;
end;works fine and all sessions are killed.
create or replace procedure kill_session(user in varchar2)
is
begin
for sessions in ( select sid, serial#
                    from   v$session
                    where  username = '||user||')
  loop
    execute immediate 'alter system kill session '''||sessions.sid||','||sessions.serial#||'''';
  end loop;
end;works not, but also now errors ar shown..
any Idea?
