You can manage integration and process errors in Oracle Integration Classic (user-managed).
Activate the service in Oracle Integration Classic when the integration is ready to go live and you can deactivate an active Integration. You can modify or clone the integration. Delete an integration that is no longer needed. See Managing Integrations in Using Integrations in Oracle Integration.
You can manage errors from the Errors pages in Oracle Integration Classic at the integration level, connection level, or specific integration instance level. See Managing Errors in Using Integrations in Oracle Integration.
