The screenshot shows the top portion of the Create Service page. The previous screenshot description describes the top half of this screenshot.
At the bottom of the screenshot is the High Availability Configuration section. You can select whether the service you are creating is a Uniform service (available on all nodes), or a Singleton service (available on one of the active servers). In the screenshot, the DEVUSERS service is configured as a Uniform service. You can also specify the server pool associated with this service, or create a new server pool. In the screenshot, the DEVUSERS service is associated with the ora.backoffice server pool.
