Replication Scenarios

In this particular configuration the suffix
ou=people,dc=example,dc=com
receives a large number of search requests. Therefore, to distribute the load, this
tree, which is mastered on Server A, is replicated to two read-only replicas located
on Server B and Server C.
For information on setting up a single-master replication environment, refer to
"Configuring Single-Master Replication" on page 302.

Multi-Master Replication

Directory Server also supports complex replication scenarios in which the same
suffix (database) can be mastered on many servers. This suffix is held in a
read-write replica on each server. This means that each server maintains a change
log for the read-write replica.
