+<h1><a name="Small_cluster" id="Small_cluster">Starting a small cluster using the NCService</a></h1>
+<p>When running a cluster using the <tt>NCService</tt> there are 3 different kind of processes involved:</p>
+
+<ol style="list-style-type: decimal">
+  
+<li><tt>NCDriver</tt> does the work of a NodeController</li>
+  
+<li><tt>NCService</tt> configures and starts an <tt>NCDriver</tt></li>
+  
+<li><tt>CCDriver</tt> does the work of a ClusterController and sends the configuration to the <tt>NCServices</tt></li>
+</ol>
+<p>To start a small cluster consisting of 2 NodeControllers (<tt>red</tt> and <tt>blue</tt>) and 1 ClusterController (<tt>cc</tt>) on a single machine only 2 configuration files are required. The first one is</p>
+<p><tt>blue.conf</tt>:</p>
+
+<div class="source">
+<div class="source">
+<pre>[ncservice]
+port=9091
+</pre></div></div>
+<p>It is a configuration file for the second <tt>NCService</tt>. This contains only the port that the <tt>NCService</tt> of the second NodeControllers listens to as it is non-standard. The first <tt>NCService</tt> does not need a configuration file, as it only uses default parameters. In a distributed environment with 1 NodeController per machine, no <tt>NCService</tt> needs a configuration file.</p>
+<p>The second configuration file is</p>
+<p><tt>cc.conf</tt>:</p>
+
+<div class="source">
+<div class="source">
+<pre>[nc/red]
+txnlogdir=/tmp/asterix/red/txnlog
+coredumpdir=/tmp/asterix/red/coredump
+iodevices=/tmp/asterix/red
+
+[nc/blue]
+port=9091
+txnlogdir=/tmp/asterix/blue/txnlog
+coredumpdir=/tmp/asterix/blue/coredump
+iodevices=/tmp/asterix/blue
+
+[nc]
+app.class=org.apache.asterix.hyracks.bootstrap.NCApplicationEntryPoint
+storagedir=storage
+address=127.0.0.1
+command=asterixnc
+
+[cc]
+cluster.address = 127.0.0.1
+http.port = 12345
+</pre></div></div>
+<p>This is the configuration file for the cluster and it contains information that each <tt>NCService</tt> will use when starting the corresponding <tt>NCDriver</tt> as well as information for the <tt>CCDriver</tt>.</p>
+<p>To start the cluster simply use the following steps</p>
+
+<ol style="list-style-type: decimal">
+  
+<li>
+<p>Set BASEDIR to location of an unzipped asterix-server binary assembly (in the source tree that&#x2019;s at <tt>asterixdb/asterix-server/target</tt>).</p>
+  
+<div class="source">
+<div class="source">
+<pre>$ export BASEDIR=[..]/asterix-server-0.8.9-SNAPSHOT-binary-assembly
+</pre></div></div></li>
+  
+<li>
+<p>Start the 2 <tt>NCServices</tt> for <tt>red</tt> and <tt>blue</tt>.</p>
+  
+<div class="source">
+<div class="source">
+<pre>$ $BASEDIR/bin/asterixncservice -config-file blue.conf &gt; blue-service.log 2&gt;&amp;1 &amp;
+$ $BASEDIR/bin/asterixncservice &gt;red-service.log 2&gt;&amp;1 &amp;
+</pre></div></div></li>
+  
+<li>
+<p>Start the <tt>CCDriver</tt>.</p>
+  
+<div class="source">
+<div class="source">
+<pre>$ $BASEDIR/bin/asterixcc -config-file cc.conf &gt; cc.log 2&gt;&amp;1 &amp;
+</pre></div></div></li>
+</ol>
+<p>The <tt>CCDriver</tt> will connect to the <tt>NCServices</tt> and thus initiate the configuration and the start of the <tt>NCDrivers</tt>. After running these scripts, <tt>jps</tt> should show a result similar to this:</p>
+
+<div class="source">
+<div class="source">
+<pre>$ jps
+13184 NCService
+13200 NCDriver
+13185 NCService
+13186 CCDriver
+13533 Jps
+13198 NCDriver
+</pre></div></div>
+<p>The logs for the <tt>NCDrivers</tt> will be in <tt>$BASEDIR/logs</tt>.</p>
+<p>To stop the cluster again simply run</p>
+
+<div class="source">
+<div class="source">
+<pre>$ kill `jps | egrep '(CDriver|NCService)' | awk '{print $1}'`
+</pre></div></div>
+<p>to kill all processes.</p>
