Abstract
A system and method for expediting the replication of at least one specified object to a replica in a distributed computer system. A source object of a source replica determines that it has an urgent change to propagate through the distributed system, and informs a replication facility at the source replica of the urgent change. The facility extracts, or is provided with, the change information from that object, and the source replica communicates information representative of the change to a destination replica. A replication facility at the destination replica provides the change information to a destination replica object, which uses the information to make itself consistent with the source replica object.
