Why is my server hanging when I try to export an SDFile?

Why is my server hanging when I try to export an SD File?

This issue becomes a problem only after a BioSAR Browser 7.2 critical update has been applied. If a user tries to export an SD File from a form that was created before the critical update was applied, the server will hang.  In order to prevent this problem, run the following script in SQLPlus Worksheet (while logged into the cs_security schema):

delete from db_form_item
where form_item_id in (
select form_item_id from db_form_item, db_formgroup, db_form
where db_formgroup.formgroup_id = db_form.formgroup_id
and db_form.form_id = db_form_item.form_id
and not exists (select 1 from db_formgroup_tables where
db_formgroup_tables.formgroup_id = db_form.formgroup_id and
db_form_item.table_id = db_formgroup_tables.table_id));
