Abstract
A Knowledge Consistency Checker (KCC) that periodically executes on each server of the computer network is provided. The KCC interacts with a data structure contained within a copy of a database located on each server, and with a replication program that executes on each server when called by the KCC. The data structure contains a list of server objects representing the servers in the network. Associated with each server objects is a list or replication objects that describe how the server is obtain a copy of a change to the database. Each replication object represents a server other than the server with which it is associated. The KCC uses the replication objects to inform the replication program from which servers to periodically request an update to the database and to the data structure. Thus, while each KCC is only responsible for creating the objects required for its own server, the replication topology of the entire network is provided to every server in the network by the periodic requests.
