Fractional Replication

The fractional replication feature enables you to restrict certain attributes from being included when modify operations are replayed on specific servers in a topology. For information about configuring fractional replication, see Configuring Fractional Replication in Sun OpenDS Standard Edition 2.2 Administration Guide.

This section describes the architecture of the fractional replication mechanism and covers the following topics:
