Problem with timers

Question

dear all
I created two timers as followed :
When_new_form_instance
-- 'INSERT_TIMER' used for fetching data from from one table and perform some
--calculations then display the rows on a non db block.
-- 'news_timer' is to move three items on the canvas.
--these items contains the latest news . it looks like the news lines.
declare
vTIMER_data timer;
vNEWS_TIMER timer;
begin
vTIMER_data := CREATE_TIMER ('INSERT_TIMER', 1000, REPEAT);
vNEWS_TIMER := create_timer('news_timer',25,repeat);
end;
-- now the two timer has created when running the form
--on the trigger when_timer_expired I write this code:
DECLARE     
vTIMER_NAME varchar2(200);     
BEGIN
vTIMER_NAME := GET_APPLICATION_PROPERTY(TIMER_NAME) ;
IF vTIMER_NAME ='news_timer' THEN
MOVE ('TICKER.N1');-- move the ticker
END IF;
IF vTIMER_NAME = ('INSERT_TIMER') THEN
vtime := to_char(SYSDATE,'HH24:MI:SS');
p_get_avg_price( :control.n_country,
:control.n_stock,
:control.from_date,
:control.n_to_date,vtime);
End If;
END;
when i run the form the the timer 'news_timer' fires every second instead of 25 milisecond .it fires after the timer 'INSERT_TIMER' fires. i want the timer 'news_timer' to fire every 25 milisecod and not to fire with the
'INSERT_TIMER' timer
please help

Answer 1

thank you Gred for your replay
in fact the I think that the problem is that the procedure that executes every 1000 milisecond perform a quey that may spends about from 5 to 8 seconds . this query gets data from a table that contains more than 2 milion records . the query is :
CURSOR avg_cur is
     SELECT ROUND(AVG(PRICE),2)N_PRICE,round(AVG(QTY),2)AVG_QTY , STOCK_CODE
     FROM HS_OPERATIONS
     WHERE STOCK_CODE = NVL(p_stock,STOCK_CODE)
          AND COUNTRY_ID = pcountry
          and the_date between pfrom_date and PTO_DATE
          AND TO_DATE(TO_CHAR(THE_TIME,'HH24:MI:SS'),'HH24:MI:SS') <=     TO_DATE( pto_TIME,'HH24:MI:SS')
     GROUP BY STOCK_CODE;
i know that this is a complicated issue.
the parameter pto_TIME represents a clock displayed on a disply item . And i need to get the avarage of price for every stock untill the second displayed on the clock.
I this that this is the big problem which cause the timers to be delyed .
I'll be so grateful if you tell me your suggestions.
thanks alot
