Configuring Multi-Master Replication
300 Netscape Directory Server Administrator’s Guide • August 2002
Initializing the Replicas for Single-Master
Replication
You can initialize the read-only replicas from the Replication Agreement Wizard,
or at anytime afterwards. For information on initializing read-only replicas, refer to
“Initializing Consumers,” on page 313.
When you have finished, the replication agreement is set up.
Configuring Multi-Master Replication
This section provides information on configuring multi-master replication. In a
multi-master configuration, two suppliers can accept updates, synchronize with
each other, and update all consumers. The consumers can send referrals for
updates to both masters. The steps described in this section provide a high-level
overview of the procedures you need to follow and cross references to the detailed
task descriptions are provided at each step.
To set up multi-master replication such as the configuration shown in Figure 8-2 on
page 286, between two suppliers Server A and Server B that each hold a read-write
replica, and two consumers Server C and Server D that each hold a read-only
replica, you need to perform the following procedures:
• Configuring the Read-Only Replicas on the Consumer Servers
• Configuring the Read-Write Replicas on the Supplier Servers
• Initializing the Replicas for Multi-Master Replication
Configuring the Read-Only Replicas on the
Consumer Servers
Perform these steps on each consumer server:
1.
Create the database for the read-only replica, if it does not exist.
For instructions, refer to “Creating Suffixes,” on page 80.
2.
Create the entry corresponding to the supplier bind DN, if it does not exist.
This is the special entry that the supplier will use to bind.
a.
In the Directory Server Console, click the Directory tab, and create an
entry. For example you could use
cn=Replication Manager,cn=config
