HP-UX Directory Server 8.1 administrator guide

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 the consumers first, then set up the suppliers, and last, initialize all the databases:
• “Configuring the read-write replicas on the supplier servers”
• “Configuring the read-only replicas on the consumer servers”
• “Setting up the replication agreements”
• “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 “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.
d. Check the Enable Changelog checkbox.
This activates all the fields in the pane below that were previously grayed out.
e. Specify a changelog by clicking the Use default button, or click the Browse button to
display a file selector.
