Hi Mark, Could you tell us who is the Guru in all this MIDAS staff and can explain how to work with such enterprise from 255 simultaneous users? Is it enterprise solution? Might be we are doing something wrong? (see my msg. from Apr 19th in this group) How to manage BDE to open more sessions using all available limits ( 48 clients x 256 sessions = 12288 per system, assuming and controlling that the only one AppServer will work with BDE on Server machine ?) Any help will be greatly appreciated Dmitri "Mark Cashman" <mcashman@temporaldoorway.com> wrote in message news:3ADD0865.96AFE583@temporaldoorway.com... > Hi, Woody! > > If you want to use CORBA and not MIDAS with a CORBA connection, then you > need to create and manage your own data transfer protocol - for instance > passing records as CORBA data structures on demand.
