[omniORB] omniORB server application shutdown

[Wernke zur Borg]

With omniORB, the ORB is a singleton object. ORB_init() will do real initialisation only for the first call. In subsequent calls it just increments the refcount and returns a pointer to 'the' ORB, so you will get the same pointer with every call. Most probably it does no harm calling it more than once, but it is of not much use either.
 
Experts please correct me if I'm wrong.

	Thank you for advise !
	Is it something omniORB specific ?
	Actually I have several ORB_init()s in one process in my Java-Application running (Java 2, Suns JavaIDL).
	I could not reproduce any troubles (yet ?).
	Kind Regards,

		Hello,
		 
		You should not call ORB_init() more than once. Use the same ORB for both server and client roles.

			Dear Sir, 
			just a question to be sure I am doing the right things. 
			**** 
			-> I develop server application supplying some interfaces using following: 
			orb1 =  CORBA::ORB_init(); 
			orb1->resolve_initial_references("RootPOA") 
			poa->activate_object(...); 
			poa->the_POAManager()->activate(); 
			orb1->run(); 
			**** 
			-> This server acts as client calling some remote interfaces as well using following: 
			orb2 =  CORBA::ORB_init(); 
			rootContext = orb2->resolve_initial_references("NameService"); 
			obj = rootContext->resolve_str(...); 
			obj->doSomemting(...); 
			orb2->destroy(); 
			**** 
			-> To shutdown the appliction I call orb1->shutdown(true) (unblocking orb1->run()) 
			-> orb1->destroy() looks to be a part of shutdown() 
			-> Calls running by orb2 are canceled as well (exception handling is done) 
			-> Appication goes down (as desired :-) 
			**** 
			-> Questions : 
			Is it the right way to shutdown an application having several activ ORBs doing orb->shutdown() on one of them ? 
			Are some side effects possible ? 

			Kind Regards 
			Evgeni Rojkov
