I am testing and somehow feeling shy for asking such a simple question:<br>
<br>
Can two or more references to different ORBS coexist?<br>
<br>
In more detail:<br>
<br>
Can there be two or more CORBA::ORB_var configured with different calls<br>
to CORBA::ORB_init(argc, argv) passing different arguments in each call?<br>
<br>
My tests are obtaining the same address for all orb pointers and the<br>
arguments to the successive calls to ORB_init seem to be ignored.<br>
<br>
Is this normal behaviour? I am trying to make the code for a program which<br>
uses servants registered under two different orbs and the result I am<br>
getting is that the second servant is registered onto the NameService of<br>
the first orb, no matter if told to register on orb2.<br>
<br>
Thanks in advance,<br>

No, omniORB can't do this. At all. There is only one global ORB.<br>

TAO and TAOX11 both can do this<br>

Hello Ramon,<br>
looking in the CORBA::ORB_init() implementation in corbaOrb.cc (ominORB 4.1.7) you will see single instance (the_orb) having reference counting.<br>
So parametrization could be done ones.<br>
But there is no limitation having/accessing servants on all available hosts/ports.<br>
You could access different NameService(s) with omni::omniURI::stringToObject(nameServiceUri) also.<br>
<br>
Best regards,<br>
Evgeni Rojkov<br>
<br>
CORBA::ORB_ptr<br>
CORBA::ORB_init(int& argc, char** argv, const char* orb_identifier,<br>
const char* options[][2])<br>
{<br>
omni_tracedmutex_lock sync(orb_lock);<br>
<br>
if( the_orb ) {<br>
the_orb->_NP_incrRefCount();<br>
return the_orb;<br>
}<br>

The naming service you register your objects in has no relationship<br>
whatsoever to the ORB. The naming service is just a collection of CORBA<br>
objects like any other objects. If you want to register object A in<br>
naming service 1 and object B in naming service 2, then just do that.<br>
There's no need for A and B to have different ORBs.<br>
<br>
Cheers,<br>

Indeed. As we say in the other thread, omniORB's ORB is a singleton and<br>
you can't have more than one.<br>
<br>
But why do you want to? Is it just about the naming service, or is it<br>
something to do with which ports your server is listening on?<br>
