You could use
poa_m->id_to_reference(id);
or
poa_m->id_to_servant(id);
If it throws ObjectNotActive, it's not active.

Thanks Matthias for the response!

So basically, I need to call poa_m->id_to_reference(id) before
poa_m->activate_object_with_id(id,si), and activate the object
in the catch block?
