Configuring 2-Way Multi-Master Replication

To set up multi-master replication such as the configuration shown in Figure 8-2,
on page 308, between two suppliers Server A and Server B, which each hold a
read-write replica, and two consumers Server C and Server D, which 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, Server C and Server D:
Create the database for the read-only replica, if it does not exist.
1.
For instructions, refer to "Creating Suffixes," on page 80.
