[omniORB] Parallel use of different namespaces

[EntonH]

Hello omniORB-Community,

is it possible to use different nameservices to work simultaneously with
different projects?
e.g. Project 1 uses NameService1
Project 2 uses NameService2
How do I initialize the nameservices and connect objects to them?

I read about this topic in the manual of omniORB but could not find an
example how to deal with it.

Greetings
EntonH

Please define the term "Project".

Let's say: Two different applications :-)

If the different name services are running on different machines, then
just start them as normal, and point applications at them using
orbInitRef or whatever as usual.

If more than one name service was on the same machine, then obviously
they can't all listen on the default port 2809, so you'd need to start
them listening on different ports. With omninames, this appears to be
the -port command line option, or alternatives involving orbEndPoint.
Again point apps at them using different InitRef settings.

Don't take my word on the precise spelling of the options above - I've
not done it myself, and haven't checked, so read the docs about them.

Perhaps I'm missing something. I can't see the problem. There's nothing
'special' about the name service - it's just another CORBA server, like
ones you could have written yourself. Except of course that apps need to
be able to find it before they can use it to look up other things.

You can resolve a NamingService via a corbaloc URL. This way you can
have even the same application resolve several different nameservices.

So instead of resolve_initial_references() you could use
ORB_var->string_to_object("corbaloc:rir:/NameService") (rir mean resolve
initial references) for the omniORB configured nameservice.
For any other nameservice you might want to use:
ORB_var->string_to_object("corbaloc:[iiop]:<host>[:port]/NameService"
