<p>By default <code>po_gnatdist</code> will use the Ada starter. So if you
have not specified <code>pragma Starter (None);</code> in the
<code>po_gnatdist</code> configuration file, you should have a starter in
your build directory, named after the main procedure defined in the
configuration file. In this case you just have to run this program.
</p>
<p>If you don’t want to use the Starter and have specified <code>pragma
Starter (None);</code> in your configuration file, then you should have, in
your Partition’Directory, one binary for each of your partitions.
You’ll have to start each of these programs manually.
</p>
<p>In both cases you must specify a name server for your application.
You can use for example the one included in PolyORB:
<samp>po_cos_naming</samp>. When running this name server it will output its
IOR URI named <code>POLYORB_CORBA_NAME_SERVICE</code>.
</p>
<p>Just ensure that you set the global environment variable
<code>POLYORB_DSA_NAME_SERVICE</code> to an IOR URI referencing the
running name server. When using the <samp>po_cos_naming</samp> name server
just set <code>POLYORB_DSA_NAME_SERVICE</code> environment variable to the
first value output for <code>POLYORB_DSA_NAME_SERVICE</code> before
launching each DSA partition.
</p>
<p>Here is a small trace output that demonstrates the setup

The client has started!
Thus spake my server upon me:Hi!
