APPARATUS AND METHOD FOR SYNCHRONIZING EMBEDDED DATABASES OF APPLICATIONS IN A FAILOVER CLUSTER

摘要

A method and computer program product in accordance with the invention includes identifying, by an application upon startup, redundant applications running in a failover cluster. Each of the application and redundant applications includes an embedded database for storing data. The application determines which embedded database of the applications contains the most recent version of data, retrieves the most recent version of data, and writes this version to its embedded database. The application then notifies the other applications and waits for the other applications to complete replication to their embedded databases. The application may then commence operation, replicate changes to its embedded database to the other applications, and generate a timestamp indicating the time the changes are made.
