-The default mode configuration setup a <em>fastasyncqueue</em> mode cluster
configuration with following
-parameters:
-<ul>
- <li>Open Membership receiver at <em>228.0.0.4</em> and send to multicast
udp port <em>8012</em></li>
- <li>Send membership every 1 sec and drop member after 30sec.</li>
- <li>Open message receiver at default ip interface at first free port
between <em>8015</em> and <em>8019</em>.</li>
- <li>Receiver message with <em>SocketReplicationListener</em> </li>
- <li>Configure a <em>ReplicationTransmitter</em> with
<em>fastasyncqueue</em> sender mode.</li>
- <li>Add <em>ClusterSessionListener</em> and <em>ReplicationValve</em>.</li>
-</ul>
-</p>
-<p>
-<b>NOTE</b>: Use this configuration when you need very quick a test cluster
with
-at your developer machine. You can change the default attributes from cluster
sub elements.
-Use following cluster attribute prefixes <em>sender.</em>,
-<b>receiver.</b>, <b>service.</b>, <b>manager.</b>, <b>valve.</b> and
<b>listener.</b>.
