A system and method for replaying writes in a replication log is provided. Tin another embodiment, the invention relates to a lubricating composition comprising a major amount of an oil of lubricating viscosity, at least one saturated fatty phosphate ester or salt, at least one polysulfide and at least one phosphorus antiwear or extreme pressure agent, wherein the lubricating composition is free of saturated fatty phosphites. In the particle beam generating assembly, a cloud of particles, for example, electrons, are generated by heating at least one tungsten filament. The first computing device determines which computing devices in the data communication network are to be made aware of the monitored attribute. One or more of plasticizers and impact modifiers are preferably also present in the alloy to provide improved strength and flexural characteristics.
