This OK? Trigger & Stored Procedure

Question

Im ready to insert my new stored procedure and triggers into the Oracle 9.2i dbase. The goal is to have specific tables that have been modifed to set off a trigger and to call a stored procedure. The stored procedure will make a quick check to see if a new scheduled job has been created to handle the update -- if not it creates a new job, if so it just exits. The scheduled job is set up to contact the same stored procedure with a different parameter after 5 mins has expired. The new call to the stored procedure by the job will make a web request to start things rolling on the web app's side.
I could have had the triggers insert new records into a seperate table which an always running scheduled job checks every 5 mins, but the updates to the tables dont occur all that often and so the scheduled job will always run and more often then not do nothing. I have it set up to run the job after 5 mins of the first change to give the dbase updater +5 mins to make total changes and make a single web request.
Please let me know if the following code will be added fine and run correctlty under Oracle 10g.
Thanks ...
CREATE OR REPLACE PROCEDURE Tourism_Cache_Refresh (WhoCalling PLS_INTEGER) AS
v_job_exists pls_integer;
v_html varchar2(32767);
loopcnt pls_integer := 0;
BEGIN
IF (WhoCalling = 0) THEN
SELECT count(*) INTO v_job_exists FROM user_scheduler_jobs WHERE job_name = 'TourismCacheRefresh';

Quantass,
Why don't you download and install an Oracle 10g instance and test it? OTN makes this possible.
Cheers,
