Replication Server characteristics

Replication Server is designed for replication installations with the following requirements:

Small numbers of databases Replication Server is designed to support replication among servers, with installations typically involving fewer than one hundred servers.
Continuously connected Connections between primary sites and replicate sites may be over a wide area network, but Replication Server is designed for situations where there is a near-continuous connection path for data exchange among the servers in the installation.
Low latency Low latency means a short lag time between data being entered at one database and being replicated to each database in the installation. With Replication Server, replication messages are sent typically within seconds of being entered at a primary site.
High volume With near-continuous connections and high performance, Replication Server is designed for a high volume of replication messages.
Heterogeneous databases Replication Server supports several leading DBMSs, and allows mapping of object names during replication, so that support for heterogeneous databases is provided.
