Configuring Multi-Master Replication
Chapter 8
Managing Replication
335
❍
On server M4, set up the following replication agreements: one with
supplier server M3, where server M3 is declared as a
consumer
for the
replica; one with supplier server M1, where server M1 is declared as a
consumer
for the replica; and one for each consumer servers, Server C1
through Server C8.
To set up a replication agreement:
a.
In the Directory Server Console, select the Configuration tab.
b.
In the navigation tree, right-click the database to replicate, and then select
New Replication Agreement.
Or highlight the database, and select New Replication Agreement from the
Object menu. This will start the Replication Agreement Wizard.
c.
Go through the steps in the replication wizard by clicking Next to move to
the following step.
When you have finished, the replication agreement is set up.
When you have configured the servers holding the read-write replicas, the
necessary replication agreements, and the servers holding the read-only replicas,
you are ready to initialize replication. You can perform this task when you create
the replication agreements on the supplier servers or at any time afterwards. For
information on the order and procedure for initializing read-only replicas, refer to
“Initializing the Replicas for Multi-Master Replication,” on page 330, and
“Initializing Consumers,” on page 345.
During this operation, do not try to reinitialize the servers. For example, do not
initialize server M1 from server M2 if you have already initialized server M2 from
server M1.
Initializing the Replicas for Multi-Master Replication
In the case of multi-master replication, you should initialize replicas in the
following order:
1.
Ensure one supplier has the complete set of data to replicate. Use this supplier
to initialize the replica on the other supplier in the multi-master replication set.
NOTE
Once you have completed these procedures, all four servers —
server M1 through server M4 — have mutual replication
agreements, which means that they can accept updates from each
other.
