By default po_gnatdist will use the Ada starter. So if you have not specified
pragma Starter (None);
in the po_gnatdist configuration file, you should
have a starter in your build dir, named after your configuration file.
In this case you just have to run this program.
If you don't want to use the Starter and have specified
pragma Starter (None);
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.
In both cases you must specify a name server for your application. You can use for example the one included in PolyORB: po_cos_naming.
Just ensure that you set the global environment variable
POLYORB_DSA_NAME_SERVICE
to an IOR URI referencing the
running name server.
