Abstract
A method, for use in a two phase commit protocol, of reducing the number of agents writing to a log and the number of points in a transaction at which the log must guarantee the durability of the data is disclosed. If all of the agents involved in a transaction have access to the same log and if in a network it is relatively expensive to send a message, but little penalty for sending a long message compared to a short one, then improved performance can be obtained by sending both the data to be written to the log and the request commit flows in the same communications buffer.
