The Implementation Repository (often shortened to IR or ImplRepo) in TAO is an activation/reactivation service. Its purpose is to maintain a registry of servers so that it can restart servers upond demand. The IR redirect requests from clients to the correct server so that servers can shutdown and restart without sacrificing the functionality of persistent IORs. Our work has been largely based on an excellent paper by Michi Henning, Binding, Migration, and Scalability in CORBA.
The person responsible is Darrell Brunsch <brunsch@cs.wustl.edu>. You can reach me by either email, through the ACE mailing list <ace-users@cs.wustl.edu>, or through the comp.soft-sys.ace newsgroup. The newsgroup mirrors the mailing list, but not the other way. Also, if you use the mailing list, it is best if you join it before sending a question, since responses are usually just replied back to the group.
