System and method for automatically distributing copies of a replicated database in a computer system

摘要

A computer implemented system, method and computer program product for automatically distributing copies of a replicated database for a computer system comprising at least first and second host computers. Each of the host computers operatively control at least one associated computer mass storage device controller coupled to commonly accessible computer mass storage devices by at least one storage device bus. The system and method comprises the step of enumerating each of the various host computers of the computer system, each of the computer mass storage device controllers associated with each host computer and each of the computer mass storage devices coupled to the storage device buses coupling the controllers. Copies of the replicated database are then automatically distributed across the computer mass storage devices such that failures of one or more of the computer mass storage device controllers or of one or more of the computer mass storage devices will not interrupt operation of the replicated database in the computer system.
