I'm working on a heterogeneous multi-processor system (a commerical product) with various types of data storage devices distributed throughout the system. This is not a typical peer-to-peer configuration in that there is usually one system that acts as a master (most of the time). The master has a redundant slave as well as several subordinate processors (each potentially with a redundant slave). It may be necessary for one of the subordinate processors to initiate a transaction (due to a state change) but we are not sure at this phase of the design. Before we go investing more time into development, we would like find out about possible programs, libraries, source code (Public Domain or Commercial) that we could possibly use. We need a data manager (not a full data base management system) that will provide the capability to perform an atomic transaction (e.g. Begin Transaction, Read, Write, Write,...,End Transaction) across distributed data in a REALTIME system. The system must be very efficient. Another big plus is the ability for a process to register for notification whenever a data element is updated (value actually changes). Does such a beast exist?
