Directory Server allows you to prioritize updates for replication. Priority is a boolean feature and is on or off. You can prioritize replication according to the following parameters:
Attribute name
For example, a password attribute can be configured to replicate immediately.
Operation type
For example, you can set up add operations to have a higher priority than modification operations.
Client identity
For example, you can specify that modifications made by administrative users have a higher priority than modifications made by regular users.
Entry or subtree
For example, you can specify that a particular group has a higher priority than other groups.
The priority rules are configured on each master replica. The master can replicate an update to one or more hubs or consumer replicas. The priority of the update is then cascaded across all of the hubs and consumer replicas. If one parameter is configured for prioritized replication, all updates that have that parameter are prioritized for replication. If multiple parameters are configured for prioritized replication, only updates that match all parameters are prioritized for replication.
See Replication Priority in Sun Java System Directory Server Enterprise Edition 6.3 Administration Guide for instructions on configuring prioritized replication using command-line tools.
