      pgpool-ha is an OCF resource script. It has to be combined with
      heartbeat or corosync and pacemaker . You have to configure those
      before you can use it.<br>

                <div>Hi Tatsuo,<br>
                  <br>
                </div>
                Thanks for your answer. <br>
              </div>
              Do you have any doc of pgpool-ha? Or setup guide? I would
              like to know what is the feature and functionality of
              pgpool-ha.<br>
            </div>
            Looks like lot of people use pgpool-ii with pgpool-ha, so I
            am also evaluating if i also need the tool for my cluster.<br>
            <br>
          </div>
          I have 2 node cluster with streaming replication:<br>
        </div>
        <div>1) node 1, Active pgpool, Primary DB<br>
        </div>
        <div>2) node 2, native pgpool, Standby DB connecting to Node 1
          using streaming replication<br>
          <br>
        </div>
        <div>So I think I should install pgpool-ha on both nodes? <br>
          <br>
        </div>
        <div>Thanks~<br>

            They are totally different beasts. The health check is HA
