Database links in an onload process

Question

In order to be able to use database links, I had to use execute immediate in my onload process. However, in doing this, the app is branching to the next page before the execute immediate statement has finished running. Is there a work around for this?
Code is:
delete from ar_assoc_activity where upper(ehs_cc)=UPPER(''||:F109_CLIENT||'');
execute immediate
'INSERT INTO ar_assoc_activity (ehs_cc, fg_id, fin_group, fiscal_year,
accounting_period, provider, fin_class, charges,
payments, adjustments, balance)
SELECT upper('''||:f109_client||'''),fg_id, fin_group, fiscal_year,
accounting_period, provider, fin_class, charges,
payments, adjustments, balance from v_ar_assoc_activity@'||:f109_link;

Answer 1

I have a chart on page x that has a link. When I click the chart to drilldown, it goes to page 40. On page 40, there is an onload process that pulls data from another database and inserts into a table. I had to use execute immediate in order to be able to insert data using a link.
I know this is not working because when I click to drilldown on my chart, I see my insert statement still running but page 40 is displayed as if no data has been loaded. However, if I wait until the insert finishes running and hit F5 to refresh the page, my data is displayed.
For testing purposes, I insert into a table when my insert begins running and then delete the record when the insert finishes.
Onload process is below:
declare
v_loaded number;
v_ehs_cc varchar2(30);
v_in_process varchar2(5);
BEGIN
select count(*) into v_loaded from ar_assoc_activity where upper(ehs_cc)=upper(:f109_client) and trunc(create_dt)=trunc(sysdate);
select count(*) into v_in_process from drilldowns where upper(report_name)='AR_WITH_ASSOC_ACTIVITY' and upper(ehs_cc)=upper(:f109_client);
if (v_in_process=0 and :p40_refresh_query='Y') or (v_in_process=0 and v_loaded=0) then
insert into drilldowns(ehs_cc,app_user,report_name,begin_load)
select upper(''||:f109_client||''),''||:app_user||'','AR_WITH_ASSOC_ACTIVITY',SYSDATE FROM DUAL;
commit;
delete from ar_assoc_activity where upper(ehs_cc)=UPPER(''||:F109_CLIENT||'');
execute immediate
'INSERT INTO ar_assoc_activity (ehs_cc, fg_id, fin_group, fiscal_year,
accounting_period, provider, fin_class, charges,
payments, adjustments, balance)
SELECT upper('''||:f109_client||'''),fg_id, fin_group, fiscal_year,
accounting_period, provider, fin_class, charges,
payments, adjustments, balance from v_ar_assoc_activity@'||:f109_link;
delete from drilldowns where upper(ehs_cc)=upper(:f109_client) and upper(report_name)='AR_WITH_ASSOC_ACTIVITY';
commit;
end if;
:P40_REFRESH_QUERY:=NULL;
END;
