Replication

The topics in this group contain information about replicating data in HCL Informix® databases by using Enterprise Replication.

Enterprise Replication is a good solution if you have geographically dispersed servers and you do not want to replicate all data. You specify what data is replicated between servers, how data conflicts are handled, and how servers are connected. Enterprise Replication servers can be on heterogeneous hardware and database server versions. If a server fails, Enterprise Replication stores the data from other servers that is not yet replicated until the network or system is operational. You can also configure a grid to simplify administration by propagating SQL statements and files from one server to all other servers in the grid.

Tip: If you want to replicate data only for high-availability, you do not need to use Enterprise Replication. You can use high-availability clusters to provide one or more copies of the primary database server. See High availability and scalability.
