- Use Case of Auto Re-Execute Functionality in ADF BC. There are use cases, when data in DB is changed by background processes and we would like to display to the user latest data available. Very common implementation for this use case is to re-execute ADF iterator and VO each time when Task Flow or UI screen is accessed. Obviously this works, but performance would suffer - usually there is no need to re-fetch data each time, it must be re-fetched only when changes are detected in DB. ADF BC provides out of the box such functionality - it can detect changes in DB and re-execute VO through Database Change Notification. Make sure to grant CHANGE NOTIFICATION system privilege to the data source user.
