Dropping a connected user from an Oracle 10g database schema

Question

Is there a better way to forcefully disconnect all users from an Oracle 10g database schema than restarting the Oracle database services?

Answer 1

my proposal is this simple anonymous block:

DECLARE
   lc_username   VARCHAR2 (32) := 'user-name-to-kill-here';
BEGIN
   FOR ln_cur IN (SELECT sid, serial# FROM v$session WHERE username = lc_username)
   LOOP
      EXECUTE IMMEDIATE ('ALTER SYSTEM KILL SESSION ''' || ln_cur.sid || ',' || ln_cur.serial# || ''' IMMEDIATE');
   END LOOP;
END;
