[omniORB] multiple omniNames instances

[Bruce Visscher]

Jonathan,

I need to understand what you are asking a little better.  Are you
asking whether you can have different threads within the same process
using different omniNames servers?  If that is the question then, I
think the answer to that is no (at least under the current (2.8.0)
implementation of omniORB).  CORBA::ORB_init is a (process) global
initialization.  Once you call it (from any thread) calling it again
from the same or different thread has no effect.

One solution would be to run each client that needs a different name
service in a seperate process.

Another solution would be to register each name service with the other. 
This is accomplished by binding the IOR of the omniNames server (I think
you use bind_context, not bind) with the other.  I just tried this
using:

	nameclt -advanced bind_context foo.names IOR:...

and it seems to work.  Now the directory tree of the other nameserver is
visible via:

	nameclt list foo.names

Now, how you keep these IORs in synch is another matter.

HTH,

Bruce Visscher
