  org.objectweb.cjdbc.controller.virtualdatabase.protocol.ReplicateLogEntries

All Implemented Interfaces:

java.io.Serializable

public class ReplicateLogEntries

extends java.lang.Object

implements java.io.Serializable

This message is used both to prepare the sending of a set of log entries to a remote controller's vdb recovery log (intialization) and to terminate it (termination). Initialization is the second step of the process to rebuild the remote recovery log from a live one, termination is the final step of the process. The process is as such so that eventually the remote vdb backends can be restored from dumps. Upon reception of this message for the initialisation phase (identified by a null dumpCheckpointName), the remote recovery log is cleared from the beginning upto the 'now' checkpoint. Subsequently, CopyLogEntry messages are sent and log entries are inserted 'as are' into the remote recovery log. Then, upon reception of this message for the termination phase (non-null dumpCheckpointName), the remote recovery log makes the dumpCheckpointName available for restore operations.
