Examples of AckMsg

org.nasutekds.server.replication.protocol.AckMsg
AckMsg messages are used for acknowledging an update that has been sent requesting an ack: update sent in Assured Mode, either safe data or safe read sub mode. The change number refers to the update change number that was requested to be acknowledged. If some errors occurred during attempt to acknowledge the update in the path to final servers, errors are marked with the following fields: - hasTimeout: Some servers went in timeout when the matching update was sent. - hasWrongStatus: Some servers were in a status where we cannot ask for an ack when the matching update was sent. - hasReplayError: Some servers made an error replaying the sent matching update. - failedServers: The list of server ids that had errors for the sent matching update. Each server id of the list had one of the 3 possible errors (timeout/wrong status /replay error) AckMsg messages are sent all along the reverse path of the path followed an update message.
