AdministeringIn addition to administering the database server, you can tune performance, replicate data, and archive data.
Enterprise ReplicationThe HCL OneDB™ Enterprise Replication Guide describes the concepts of data replication using HCL® OneDB® Enterprise Replication, including how to design your replication system, as well as administer and manage data replication throughout your enterprise.
Planning and designing for Enterprise ReplicationBefore you set up your replication system, plan how to include Enterprise Replication into your database server environment, design your database schema by following Enterprise Replication requirements, and then design your replication system between database servers.
Replication system designWhen you design a replication system, you make three main decisions: how the information flows between servers, how to resolve conflicts between replicated data, and the topology of the network of servers.
Choosing a Replication Network Topology
Fully Connected Topology

Fully Connected Topology

Fully connected replication topology indicates that all database servers connect to each other and that Enterprise Replication establishes and manages the connections. Replication messages are sent directly from one database server to another. No additional routing is necessary to deliver replication messages. Fully Connected Topology shows a fully connected replication topology. Each database server connects directly to every other database server in the replication environment.

If necessary, you can also add high-availability clusters and a backup server to any server to provide high availability. For more information, see High-availability replication systems.
