Configuring Replication Status

Each replicated domain in a replicated topology has a certain replication status, depending on its connections within the topology, and on how up to date it is with regard to the changes that have occurred throughout the topology. For more information, see Replication Status in Sun OpenDS Standard Edition 2.0 Architectural Reference.

Replication status is generated automatically, based on how up to date a server is within the replicated topology. The only parameter that can be configured is the degraded status threshold. This parameter defines the maximum number of changes that can be in the replication server's queue for all domains of the directory servers that are connected to this replication server. When this number is reached, for a specific directory server, that server is assigned a degraded status. The degraded status remains until the number of changes drops beyond this value.

Note - The default value of the degraded status threshold should be adequate for most deployments. Only modify this value if you observe several timeout messages in the logs when assured replication is configured.

To Configure the Degraded Status Threshold

The default number of changes defined by this threshold is 5000. This example sets the threshold to 6000, to take into account a network with more latency.
