Oracle Integration Cloud: Building Integrations That Survive Production · Module 13 · Monitoring, tracking and alerting
The silent failure: nothing ran
Lesson 133 of 175 · 3 min
A schedule that stopped and an event that never fired produce NO FAILED INSTANCE AT ALL. The heartbeat check that makes absence visible. Everything in this module so far monitors instances that exist. This lesson is about the failure that produces none, and it is the one that runs longest before anybody notices. A SCHEDULE THAT STOPPED LOOKS LIKE A QUIET PERIOD. A deactivated integration, a schedule somebody paused during a change, a flow that failed to reactivate after a version update — Module 7's territory. There is no failed instance because nothing ran. The console is green, the alert channel is silent, and every dashboard reads normal. AN EVENT THAT NEVER FIRED IS THE SAME SHAPE — Module 10's third failure, where a Fusion configuration change stops an event being raised and the subscribing integration simply never triggers. THE COMMON PROPERTY IS THAT MONITORING ANSWERS "DID WHAT RAN SUCCEED"…
