Sun Java System Directory Server Enterprise Edition 6.1 Reference

Replication Change Log

All modifications received by a master replica are recorded in a change log. A change log is maintained on all master replicas and hub replicas.

In earlier versions of Directory Server, the change log was accessible over LDAP. In this version of the product, the change log is not accessible over LDAP but is stored in its own database. If your application needs to read the change log, use the retro change log plug-in for backward compatibility. For more information about the retro change log plug-in, see Replication and the Retro Change Log Plug-In.
