Triggers on every table in schema

Question

Hi All,
I want to know every details that whenever someone performs a DML in schema A on any tables to logged into a table.
I have attempted these:
-Create log table
CREATE TABLE audit_rst(
user_id VARCHAR2(30),
session_id NUMBER,
host varchar2(30),
ip_add varchar2(30),
action CHAR(3),
date_executed DATE);
--Create a row based trigger for every tabel available
--this exampel shows only one table
CREATE OR REPLACE TRIGGER AUDIT_cc_2008
AFTER INSERT OR DELETE OR UPDATE ON cc_2008 FOR EACH ROW
DECLARE
v_operation VARCHAR2(10) := NULL;
BEGIN
IF INSERTING THEN
   v_operation := 'I';
ELSIF UPDATING THEN
   v_operation := 'U';
ELSE
   v_operation := 'D';
END IF;
IF INSERTING OR UPDATING THEN
  INSERT INTO audit_rst(
  USER_ID,
  SESSION_ID,
  HOST,
  ACTION,
  DATE_EXECUTED)
  VALUES (
  user,
  sys_context('USERENV','SESSIONID'),
  sys_context('USERENV','HOST'),
  SYS_CONTEXT('USERENV', 'IP_ADDRESS', 15)
  v_operation, SYSDATE);
ELSE
  INSERT INTO audit_rst (
  USER_ID,
  SESSION_ID,
  HOST,
  ACTION,
  DATE_EXECUTED)
  VALUES (
  user,
  sys_context('USERENV','SESSIONID'),
  sys_context('USERENV','HOST'),
  v_operation, SYSDATE);
END IF;
END;Do I need to create this trigger for every table available in teh schema...or is tehre a schema level trigger that can scan through the schema and pick up any dml changes to any table and log it into teh audit_rst table?

Schema-Level Events for Trigger Definitions Event
SERVERERROR : Oracle fires the trigger whenever a server error message is logged.
LOGON : Oracle fires the trigger after a client application logs on to the database successfully.
LOGOFF : Oracle fires the trigger before a client application logs off the database.
CREATE : Oracle fires the trigger whenever a CREATE statement adds a new database object to the schema.
DROP : Oracle fires the trigger whenever a DROP statement removes an existing database object from the
schema.
ALTER : Oracle fires the trigger whenever an ALTER statement modifies an existing database object in the
schema.
