   Once you have added channels for all of the replication sources,
      issue a

    <code class="literal">

   statement to
      start replication. When you have enabled multiple channels on a
      replica, you can choose to either start all channels, or select a
      specific channel to start. For example, to start the two channels
      separately, use the
