Initializing Consumers
Chapter 8 Managing Replication 345
Initializing Consumers
Once you have created a replication agreement, you must initialize the consumer;
that is, you must physically copy data from the supplier server to the consumer
servers. This section first describes consumer initialization in detail and then
provides instructions on the two different methods for initializing consumers. This
section is divided into the following parts:
• When to Initialize a Consumer
• Online Consumer Initialization Using the Console
• Manual Consumer Initialization Using the Command-Line
• Filesystem Replica Initialization
When to Initialize a Consumer
Consumer initialization involves copying data from the supplier server to the
consumer server. Once the subtree has been physically placed on the consumer, the
supplier server can begin replaying update operations to the consumer server.
Under normal operations, the consumer should not ever have to be initialized
again. However, if the data on the supplier server is restored from backup for any
reason, then you should reinitialize all of the consumers supplied by it.
You can either initialize the consumer online using the Console or manually using
the command-line. Online consumer initialization using the Console is an effective
method of initializing a small number of consumers. However, since each replica is
initialized in sequence, this method is not suited to initializing a large number of
replicas. Online consumer initialization is the method to use when you initialize
the consumer while configuring the replication agreement on the supplier server.
Manual consumer initialization using the command-line is a more effective method
of initializing a large number of consumers from a single LDIF file.
