I have an Oracle ADF (ADF Faces) application that integrates with several third-party systems. Sometimes those systems are unavailable. We want to:
- Show a banner on the page when a DB configuration flag is
true, including a message pulled from the DB.
- When those systems come back online, we’ll update the flag to
false in the DB.
- Already logged-in users (without a full page reload) should either:
- See a notification/toast that “Systems are back online,” and the banner should disappear, or
- The banner should disappear quietly but ideally with a subtle notification
What is the best approach in Oracle ADF to reflect this change in real time (or near real-time) for active sessions?
