ABSTRACT:
A method for providing high availability in a production information system is described. The information system consists of a primary and a secondary copy running on a dual machine architecture. A backup database is added to the system which is updated daily from a transaction log. Database maintenance and archive procedures are performed on the data in the backup database relieving the primary and secondary databases of this activity. Database conversion is performed periodically, and the backup database is used to fill in for the primary and secondary databases when they are being converted.
