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.
