Linux — CORBA omniorb C ++ несколько слуг

Привет всем, я новичок в CORBA C ++, я прочитал учебник о том, как установить CORBA в Linux, как он работает, и код прекрасно компилируется, я хочу выполнить более одного экземпляра сервера, потому что я хочу создать одноранговый. например, когда я создаю один экземпляр сервера и несколько экземпляров клиента работает нормально, но когда я пытался выполнить два или более экземпляров сервера, чтобы получать сообщения от клиентов, только последний экземпляр сервера получал сообщения, кто-нибудь может мне помочь?

Вот мой код для сервера и клиента

server.cpp

#include "MyExampleInterface_impl.h"#include <iostream>
#include <CORBA.h>
#include <Naming.hh>

/** Server name, clients needs to know this name */
#define SERVER_NAME     "MyServerName"
using namespace std;

int main(int argc, char ** argv)
{
cerr << "CORBA SERVER RUNNING..." << endl;
try {

//------------------------------------------------------------------------
// Initialize CORBA ORB
//------------------------------------------------------------------------
CORBA::ORB_ptr orb = CORBA::ORB_init(argc, argv);

//------------------------------------------------------------------------
// Initialize POA: Get reference to root POA
//
// Servant must register with POA in order to be made available for client
// Get reference to the RootPOA.
//-----------------------------------------------------------------------
CORBA::Object_var poa_obj = orb->resolve_initial_references("RootPOA");
PortableServer::POA_var poa = PortableServer::POA::_narrow(poa_obj);
PortableServer::POAManager_var manager = poa->the_POAManager();

//------------------------------------------------------------------------
// Create service
//------------------------------------------------------------------------
MyExampleInterface_impl * service = new MyExampleInterface_impl;
cerr << "ya se creo el servicio procediendo a crear instancia" << endl;
try {
//------------------------------------------------------------------------
// Bind object to name service as defined by directive InitRef
// and identifier "NameService" in config file omniORB.cfg.
//------------------------------------------------------------------------
CORBA::Object_var ns_obj = orb->resolve_initial_references("NameService");
if (!CORBA::is_nil(ns_obj)) {
//------------------------------------------------------------------------
// Narrow this to the naming context
//------------------------------------------------------------------------
CosNaming::NamingContext_ptr nc = CosNaming::NamingContext::_narrow(ns_obj);

//------------------------------------------------------------------------
// Bind to CORBA name service. Same name to be requested by client.
//------------------------------------------------------------------------
CosNaming::Name name;
name.length(1);
name[0].id = CORBA::string_dup(SERVER_NAME);
name[0].kind = CORBA::string_dup("");
nc->rebind(name, service->_this());

//------------------------------------------------------------------------
// Intizialization ready, server runs
//------------------------------------------------------------------------
cout << argv[0] << " C++ (omniORB) server '" << SERVER_NAME << "' is running .." << endl;
}
} catch (CosNaming::NamingContext::NotFound &) {
cerr << "Caught CORBA exception: not found" << endl;
} catch (CosNaming::NamingContext::InvalidName &) {
cerr << "Caught CORBA exception: invalid name" << endl;
} catch (CosNaming::NamingContext::CannotProceed &) {
cerr << "Caught CORBA exception: cannot proceed" << endl;
}

//------------------------------------------------------------------------

//------------------------------------------------------------------------
manager->activate();
//------------------------------------------------------------------------
// Accept requests from clients
//------------------------------------------------------------------------
cerr << "aceptando peticiones de cliente con run()" << endl;
orb->run();
cerr << "hecho ahora esperando..." << endl;
//------------------------------------------------------------------------
// Clean up
//------------------------------------------------------------------------
//delete service;

//------------------------------------------------------------------------
// Destroy ORB
//------------------------------------------------------------------------
orb->destroy();

cerr << "Caught CORBA exception: unknown exception" << endl;

cerr << "Caught CORBA exception: system exception" << endl;
