Class ReplicaFeederSyncup

java.lang.Object

com.sleepycat.je.rep.stream.ReplicaFeederSyncup

public class ReplicaFeederSyncup
extends Object

Establish where the replication stream should start for a replica and feeder pair. The replica compares what is in its log with what the feeder has, to determine the latest common log entry matchpoint - If the replica has applied log entries after that matchpoint, roll them back - If a common matchpoint can't be found, the replica will need to do a network restore.

execute

public void execute(LocalCBVLSNTracker cbvlsnTracker)
             throws IOException,
                    DatabaseException,
                    InterruptedException,
                    InsufficientLogException,
                    Replica.HardRecoveryElectionException

The replica's side of the protocol.

Throws:

InterruptedException

IOException

DatabaseException

setupHardRecovery

public RollbackException setupHardRecovery()
                                    throws IOException

Hard recovery: truncate the files, repeat recovery. If this hard recovery came about before the ReplicatedEnvironment was fully instantiated, we will recreate the environment under the covers. If this came while the replica was up and supporting existing Environment handles, we must invalidate the environment, and ask the application to reopen.

Throws:

IOException

setGlobalSyncupEndHook

public static void setGlobalSyncupEndHook(ReplicaFeederSyncup.TestHook<Object> syncupEndHook)

setRollbackTestHook

public static void setRollbackTestHook(TestHook<ReplicaFeederSyncup> rollbackHook)
