Change Number Control Plugin

The Change Number Control Plugin returns the change number generated by the replication subsystem.

The Change Number Control Plugin returns the change number generated by the Multi-Master Replication subsystem when : - the Multi-Master Replication is configured and enabled - the request is a write operation (add, delete, modify, moddn) - the control is part of a request. If all of the above are true, the response contains a control response with a string representing the change number. The implementation for the change number control plug-in is contained in the org.opends.server.plugins.ChangeNumberControlPlugin class. It must be configured with the postOperationAdd, postOperationDelete, postOperationModify and postOperationModifyDN plug-in types, but it does not have any other custom configuration.

Parent

The Change Number Control Plugin object inherits from Plugin.
