摘要:
A method for synchronization of data stored in redundant servers of a process control system is described. The redundant servers include an active server and at least one standby server, in communication with a plurality of applications. The method includes generating a memory snapshot of information stored in a plurality of active server memory locations at a predetermined time. The information stored in the plurality of active server memory locations includes application operating data for the plurality of applications and the memory snapshot includes a data structure that includes a copy of the information stored in the plurality of active server memory locations. The method also includes transmitting the memory snapshot from the active server to the at least one standby server, and storing the memory snapshot at the at least one standby server.
