Replication logs are stored in the replication repair logs. Changes are recorded in the change logs. For information on accessing these logs, see Accessing Logs
When replicating global index catalogs, provision disk space for change logs. By default, these logs store changes for a 24 hour period. Approximately 100Mb is required for 300,000 write operations. With the default value of 24 hours, the log must be configured based on the expected size of the service during that period. A hint is to provision approximately 150Gb for 5 000 modifications per second over 24 hours. For information how to configure logs, see Configuring Logs With dsconfig.
