An incident is a single occurrence of a problem. When a problem (critical error) occurs multiple times, an incident is created for each occurrence. Incidents are timestamped and tracked in the Automatic Diagnostic Repository (ADR). Each incident is identified by a numeric incident ID, which is unique within the ADR. When an incident occurs, the database:
Makes an entry in the alert log.
Sends an incident alert to Cloud Control.
Gathers first-failure diagnostic data about the incident in the form of dump files (incident dumps).
Tags the incident dumps with the incident ID.
Stores the incident dumps in an ADR subdirectory created for that incident.
