Configuring Cascading Replication
302 Netscape Directory Server Administrator’s Guide • May 2002
To set up cascading replication such as the configuration shown in Figure 8-3 on
page 284, between the supplier on Server A that holds a read-write replica, the
consumer/supplier on Hub Server B that holds a read-only replica, and the
consumer on Server C that holds a read-only replica, you need to perform the
following procedures:
• Configuring the Read-Only Replica on the Consumer Server
• Configuring the Read-Only Replica on the Hub Supplier
• Configuring the Read-Write Replica on the Supplier Server
• Initializing the Replicas for Cascading Replication
Configuring the Read-Only Replica on the
Consumer Server
1.
On the consumer server, create the database for the replica if it does not exist.
For instructions, refer to “Creating Suffixes,” on page 76.
2.
On the consumer server, 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.
3.
On the consumer server, specify the replication settings for the read-only
replica.
a.
In the Directory Server Console, click the Configuration tab.
b.
In the navigation tree, expand the Replication folder, and highlight the
replica database.
The Replica Settings tab is displayed in the right-hand side of the window.
c.
Check the Enable Replica checkbox.
d.
In the Replica Role section, select the Dedicated Consumer radio button.
e.
In the Common Settings section, specify a purge delay in the Purge delay
field.
This option indicates how often the state information stored in the
replicated entries is purged.
