Ingres Replicator is a database connectivity system that manages replication. Replication can occur between different databases on the same machine or on different machines on the other side of the world, as long as they are in a distributed network. So instead of having all your users throughout the world access the same database in one location, you can have a replicated database in every region. Ingres Replicator works behind the scenes to replicate data asynchronously by transaction. Designed as a layer that sits between the database and an application, Ingres Replicator is transparent to users.
Data integrity is enforced through a two-phase commit protocol.
Data from a transaction are not available for replication until the transactions have committed locally. This ensures data integrity in the event of a source, target, or network failure. Inc. All rights reserved.
