Abstract :
A High Voltage system has been designed to allow multiple users (clients) access to the database of measured values and settings. This database is actively maintained in real time for a given mainframe containing multiple modules each having their own database. With limited CPU and memory resources the mainframe system provides a data coherency scheme for multiple clients which (1) allows the client to determine when and what values need to be updated, (2) allows for changes from one client to be detected by another client, and (3) does not depend on the mainframe system tracking client accesses
