ABSTRACT:
A Registration protocol is used in transaction processing for normal operations. If an error occurs, the system reverts to a Full Broadcast protocol. The Registration Protocol reduces the number of messages that are sent among CPUs in a cluster thereby permitting performance improvements in the system. The Registration Protocol has Begin, DP2Check, Phase1Flush and Phase2(lock release) phases just as does the Full Broadcast Protocol, thereby permitting the Full Broadcast protocol to step in at any phase after an error is detected.
