Abstract

Distributed data acquisition and control systems are envisioned as the solution to objectives sought for a long time: reliable online systems which degrade gracefully. Critical applications however require a great deal of communication of both commands and data which in turn leads to distributed data bases and their attendant problems. The most critical software problem in such systems is error recovery because of the many modes of failure which may occur. Software architecture which leads to feasible distrubuted system errir recovery is discussed, including atomic transactions, intention lists, and controlled data sets.
