APEX change control

Oracle Tips by Burleson Consulting

Change control is critical for all Apex (HTML-DB) applications and management must have a change control procedure that captures all APEX components.  Oracle Application Express (OAE) has some built-in reports that provide basic information, but a formal change control procedure requires scripts to locate all changed components.

Home>Application Builder>Application xxx>Application Reports>Activity Reports

The ultimate goal of Apex change control is to have a script that accepts the last production date and build a list of all schema components and APEX chunks and exports them for migration into production.

Here is an APEX script to query wwv_flow_steps, wwv_flows, and wwv_builder_audit_trail to display all components AFTER the last production migration date! This is not a complete change control solution because it does not consider inter-application dependencies, but it will reliably produce a list of APEX components after a specific date:

select t.audit_date,
        ( t.audit_action,
         'I', 'Create',
         'D', 'Delete',
              'Change' ) audit_action,
       t.flow_id,            application_name,
       t.page_id,            page_name,
from   wwv_flow_steps s,
       wwv_flows f,
       wwv_flow_builder_audit_trail t
where = t.flow_id
and    s.flow_id = t.flow_id
and = t.page_id
and    t.audit_date > :migcheck_last_prod_migration_datetime
order by t.audit_date desc;
