8.5. Configuring Multi-Master Replication
This section provides information on configuring multi-master replication. In a multi-master
configuration, many suppliers can accept updates, synchronize with each other, and update all
consumers. The consumers can send referrals for updates to all masters.
Directory Server supports 4-way multi-master replication. To set up multi-master replication such
as the configuration shown in
Figure 8.3, “Multi-Master Replication (Four Masters)”
, set up all of the
consumers first, then set up the suppliers, and last, initialize all of the databases:
•
Section 8.5.1, “Configuring the Read-Write Replicas on the Supplier Servers”
•
Section 8.5.2, “Configuring the Read-Only Replicas on the Consumer Servers”
•
Section 8.5.3, “Setting up the Replication Agreements”
•
Section 8.5.4, “Preventing Monopolization of the Consumer in Multi-Master Replication”
NOTE
More than 10 databases running with replication or more than 20 replication agreements
on a supplier can cause performance degradation. To support that many consumers,
introduce hub replicas between the suppliers and consumers. See
Section 8.6,
“Configuring Cascading Replication”
.
8.5.1. Configuring the Read-Write Replicas on the Supplier Servers
Set up each supplier server. The first supplier configured should be used to initialize the other
suppliers in the multi-master replication environment.
1. Specify the supplier settings for the server.
a. In the Directory Server Console, select the
Configuration
tab.
b. In the navigation tree, select the
Replication
folder.
c. In the right-hand side of the window, select the
Supplier Settings
tab.
