<p>The next step is to let <a class="reference internal" href="/wiki/display/ECFLOW/Glossary#term-ecflow-server"><em class="xref std std-term">ecflow_server</em></a> know about your <a class="reference internal" href="/wiki/display/ECFLOW/Glossary#term-suite"><em class="xref std std-term">suite</em></a> or to “load” the <a class="reference internal" href="/wiki/display/ECFLOW/Glossary#term-suite-definition"><em class="xref std std-term">suite definition</em></a> file.</p>
<p>This checks the file <tt class="file docutils literal"><span class="pre">test.def</span></tt> and describes the <a class="reference internal" href="/wiki/display/ECFLOW/Glossary#term-suite"><em class="xref std std-term">suite</em></a> to the <a class="reference internal" href="/wiki/display/ECFLOW/Glossary#term-ecflow-server"><em class="xref std std-term">ecflow_server</em></a>.</p>
<p>This can be done in several ways, depending on how the <a class="reference internal" href="/wiki/display/ECFLOW/Glossary#term-suite"><em class="xref std std-term">suite</em></a> was created.</p>

<p>If everything is OK, you should have defined a <a class="reference internal" href="/wiki/display/ECFLOW/Glossary#term-suite"><em class="xref std std-term">suite</em></a> in the server.</p>
<p>Have a look in the window running the <a class="reference internal" href="/wiki/display/ECFLOW/Glossary#term-ecflow-server"><em class="xref std std-term">ecflow_server</em></a>, and look at the log file</p>
<p><strong>What to do:</strong></p>
<ol class="arabic simple">
<li>Load the definition file. Choose between loading as a text file, or using python api.</li>
<li>If using python examine <tt class="file docutils literal"><span class="pre">test.def</span></tt> and create the file <tt class="file docutils literal"><span class="pre">client.py</span></tt>.</li>
