[omniORB] reliability

[Okeefe, Michael K]

Yes, and there are some good comments in the list archives:
http://www.omniorb-support.com/pipermail/omniorb-list/1999-August/013435.html

The load balancing article mentioned in the above e-mail is dated and covers BOAs.  I think the general ideas should be supported in omniORB, i.e. using interceptors and the name service, however we didn't implement this as we are running on Citrix servers anyway (because of other requirements) and Citrix has load balancing.

Ok !
I did not catch my call the object function (I only catched call to
omniobr func ...).
Now I catch everything as you suggested me and my program became more
reliable of course.

Thank you.
Now I would like to know if it is possible to 'load balance' object
between a pool of servers ... ?

Regards,
Julien
