<div >
<div >Let’s add another <a href="/wiki/display/ECFLOW/Glossary#term-task"><em >task</em></a> named <strong>t2</strong>.</div>
<div >You will need to modify the <a href="/wiki/display/ECFLOW/Glossary#term-suite-definition"><em >suite definition</em></a> file and add a new script.</div>
<div >First modify the <a href="/wiki/display/ECFLOW/Glossary#term-suite-definition"><em >suite definition</em></a></div>
</div>
<div ><pre># Definition of the suite test
suite test
edit ECF_HOME "$HOME/course"
task t1
task t2
endsuite</pre>
</div>
<div >
<div >As before replace $HOME with the real path to your home directory.</div>
<div >You must also create a file <tt ><span >t2.ecf</span></tt> in <tt ><span >$HOME/course/test</span></tt>.</div>
<div >Simply copy <tt ><span >t1.ecf</span></tt>.</div>
</div>
<p>Then you must load the file again:</p>
<div ><pre>> ecflow_client --load test.def</pre>
</div>
<div >
<p >Warning</p>
<p >This will fail because the suite is already loaded</p>
</div>
<p>Because the suite is already defined, you need to delete and reload it first:</p>
<div ><pre>> ecflow_client --delete=_all_
> ecflow_client --load=test.def</pre>
</div>
<p>Then restart the suite:</p>
<div ><pre>> ecflow_client --begin=test</pre>
</div>
<p>If you are using the <a href="/wiki/display/ECFLOW/ecFlow+Python+Api#python-api"><em>ecFlow Python Api</em></a>:</p>

<div >Rather than deleting, loading and beginning the suite every time you can replace</div>
<div >all or part of the suite for example to replace whole suite.</div>
</div>
<div ><pre>> ecflow_client --replace /test test.def</pre>
</div>
<p>or to replace part of the suite:</p>
<div ><pre>> ecflow_client --replace /test/t2 test.def</pre>
</div>
<p>In python this would be:</p>
<div ><div ><pre><span >#!/usr/bin/env python2.5</span>

<div >
<div >It is good practice to suspend your suite before you reload any part of it.</div>
<div >In <a href="/wiki/display/ECFLOW/Glossary#term-ecflowview"><em >ecflowview</em></a> right click on the suite and select “Suspend”.</div>
<div >Once you made your change you can right click on the suite and “Resume” it.</div>
</div>
<div >
<p >Note</p>
<p >For <strong>brevity</strong> the following examples, will not show the loading of the suite.</p>
</div>
<p>What to do:</p>
<ol >
<li>Create the new task</li>
<li>Create <tt ><span >t2.ecf</span></tt> by copying from <tt ><span >t1.ecf</span></tt></li>
<li>Begin the suite</li>
<li>In <a href="/wiki/display/ECFLOW/Glossary#term-ecflowview"><em >ecflowview</em></a>, watch the two task running. They should run at the same time</li>
</ol>
