[omniORB] How to use more than one naming server?

[Mark Johnson]

I'm confused from reading the documentation about how to configure a server
and a client to use redundant naming servers.  We have to run our
applications to use a fail over naming service in case we lose the primary
name server.

But I'm confused, in the examples they always the ORB_init() method to pass
the command line and always use "RootPOA" to register the servant.  If I
wanted to use two (or more) naming services and have the servant register
with all of them would I do something like this?

	myserver -ORBInitRef FOO=corbaname::foo.onfiber.com
BAR=corbaname::bar.onfiber.com

And then in my server code do something like this:

  void MyServerApp::setup( int argc, char * argv[] )
  {
	CORBA::ORB_var orb = CORBA::ORB_init( argc, argv, "omniORB3" );

	// should this ALWAYS be "RootPOA"?
	//
	CORBA::Object_var fooObj = orb->resolve_initial_references( "FOO" );

	CORBA::Object_var barObj = orb->resolve_initial_references( "BAR" );

	PortableServer::POA_var fooPOA = PortableServer::POA::_narrow(
fooObj );	PortableServer::POA_var barPOA =
PortableServer::POA::_narrow( barObj );

	Servant_i * servant = new Servant_i();
	
	// register with both naming servers...
	//
	PortableServer::ObjectId_var oid = fooPOA->activate_object( servant
);
	PortableServer::ObjectId_var oid = barPOA->activate_object( servant
);

	// etc..
	PortableServer::POAManager_var fooPMAN = fooPOA->the_POAManager();
	PortableServer::POAManager_var barPMAN  = barPOA->the_POAManager();

	fooPMAN->activate();
	barPMAN->activate();

	// etc...
	bindObjectToName(...)
  }

I assume that I would do the thing when I called
'resolve_initial_reference()' in the 'bindObjectToName()' and select FOO or
BAR (if there was an exception thrown on FOO).

Do I understand this correctly? 

I'll save my questions about the client after I understand this part
first...

Thanks for your help...
