<li>The IRS demo web interface - a web interface to the IRS demo.</li>

recommended if you are just wanting to see them run, using IntelliJ can be helpful if you want to debug or

<p>This demo brings up three nodes: Bank A, Bank B and a notary/network map node that they both use. Bank A will
be the buyer, and self-issues some cash in order to acquire the commercial paper from Bank B, the seller.</p>
<p>To run from the command line:</p>

<li>Run <code class="docutils literal"><span class="pre">./gradlew</span> <span class="pre">samples:trader-demo:runSeller</span></code> to trigger the transaction. You can see both sides of the

<p>This demo brings up three nodes: Bank A, Bank B and a node that runs a notary, a network map and an interest rates
oracle together. The two banks agree on an interest rate swap, and then do regular fixings of the deal as the time
on a simulated clock passes.</p>
<p>To run from the command line:</p>
<ol class="arabic simple">
<li>Run <code class="docutils literal"><span class="pre">./gradlew</span> <span class="pre">samples:irs-demo:deployNodes</span> <span class="pre">samples:irs-demo:installDist</span></code> to install configs and a command line tool under <code class="docutils literal"><span class="pre">samples/irs-demo/build</span></code>.</li>
<li>Change to the <code class="docutils literal"><span class="pre">samples/irs-demo/build</span></code> directory.</li>
<li>Run <code class="docutils literal"><span class="pre">./nodes/runnodes</span></code> (or <code class="docutils literal"><span class="pre">runnodes.bat</span></code> on Windows) to open up three new terminals with the three nodes.</li>
<li>Run <code class="docutils literal"><span class="pre">./install/irs-demo/bin/irs-demo</span> <span class="pre">--role</span> <span class="pre">UploadRates</span></code> (or use <code class="docutils literal"><span class="pre">irs-demo.bat</span></code> on Windows). You should see a
message be printed to the first node (the notary/oracle/network map node) saying that it has accepted some new
interest rates.</li>
<li>Now run <code class="docutils literal"><span class="pre">irs-demo</span></code> as in step 4, but this time with <code class="docutils literal"><span class="pre">--role</span> <span class="pre">Trade</span> <span class="pre">1</span></code>. The number is a trade ID. You should
see lots of activity as the nodes set up the deal, notarise it, get it signed by the oracle and so on.</li>
<li>Now run <code class="docutils literal"><span class="pre">irs-demo</span> <span class="pre">--role</span> <span class="pre">Date</span> <span class="pre">2016-12-12</span></code> to roll the simulated clock forward and see some fixings take place.</li>

<li>Open the Corda samples project in IntelliJ and run the &#8220;IRS Demo: Run Nodes&#8221; configuration</li>
<li>Run &#8220;IRS Demo: Run Upload Rates&#8221; to upload rates to the oracle.</li>

<li>Run &#8220;IRS Demo: Run Date Change&#8221; to run the fixings.</li>

<p>In the &#8220;IRS Demo: Run Nodes&#8221; window you&#8217;ll see a lot of activity when you run the trade and when you run the date change.
The date change rolls the clock forwards and causes the nodes to agree on the fixings over a period.</p>
