摘要
According to a method of access to a shared data record subject to contemporaneous read and write access by multiple requesters, a requester reads a shared data record including a payload and a first checksum. The requester calculates a second checksum of the payload of the data record. If the first and second checksums are not equal, the requester again reads the shared data record, including a third checksum, and calculates a fourth checksum of the payload of the shared data record. If the third and fourth checksums are equal, the requester processes the shared data record as valid, and if the second and fourth checksums are equal, the requester handles the shared data record as corrupt.
