  title: Oracle OCI Rename Compute Instance
  summary: Read an instance to capture its ETag, then update its display name with an optimistic concurrency guard.
  description: >-
    Changes the user-friendly display name of a compute instance safely. The
    workflow reads the instance to capture its current ETag, then issues an
    update that sets the new display name while enforcing the ETag through the
    if-match header so the change only applies if the instance has not been
    modified concurrently. Every step spells out its request inline so the flow
    can be read and executed without opening the underlying OpenAPI description.
