  title: Oracle OCI Start Compute Instance
  summary: Read a stopped instance, send the START action, then poll until it reports RUNNING.
  description: >-
    Powers on a stopped compute instance and confirms it came back online. The
    workflow reads the current instance to capture its ETag, issues the START
    instance action guarded by that ETag, and then polls getInstance until the
    lifecycle state becomes RUNNING. Every step spells out its request inline so
    the flow can be read and executed without opening the underlying OpenAPI
    description.

  summary: Start a stopped compute instance and confirm it reaches RUNNING.
  description: >-
    Reads the instance, performs the START action with an if-match guard, and
    polls the lifecycle state until the instance is RUNNING.
