  title: Oracle GoldenGate Restart Abended Extract
  summary: Inspect an Extract's status and restart it only when it has abended.
  description: >-
    Recovery flow for a failed Extract. It reads the Extract status and branches:
    when the process has abended it issues a START command and polls until the
    process is running again; when the process is already running it ends without
    taking action. Every step spells out its request inline so the flow can be
    read and executed without opening the underlying OpenAPI description.
