Stratus Computer Inc, Marlborough, Massachusetts will add functionality to an implementation of the Open Software Foundation’s Distributed Computing Environment by integrating DCE with the database messaging system it picked up from its acquisition of Isis Distributed Systems Inc in December last year. Integrated with the Distributed Computing Environment, the software – which was developed at Cornell University and marketed by Ithaca, New York-based Isis since 1991 – will enable Distributed Computing Environment clients to call multiple servers, rather than just one, at the same time, with the straight DCE remote procedure call. Isis protocols sit on top of TCP/IP and enable servers to be grouped so that databases can be spread across machines for reliability and parallel execution.
