Class ReplicationTimeoutType

java.lang.Object
  com.sleepycat.db.ReplicationTimeoutType

public final class ReplicationTimeoutType
extends Object

The ReplicationTimeoutType defines the types of timeouts that can beconfigured for the Berkeley Db replication functionality.

The class is used in the Environment.setReplicationTimeoutmethod.

Field Summary

static ReplicationTimeoutType	ACK_TIMEOUT Configure the amount of time the replication manager's transport function waits to collect enough acknowledgments from replication group clients, before giving up and returning a failure indication.
static ReplicationTimeoutType	CHECKPOINT_DELAY Configure the amount of time the replication manager will delay between completing a checkpoint and writing a checkpoint record into the log.
static ReplicationTimeoutType	CONNECTION_RETRY Configure the amount of time the replication manager will wait before trying to re-establish a connection to another site after a communication failure.
static ReplicationTimeoutType	ELECTION_RETRY Configure the amount of time the replication manager will wait before retrying a failed election.
static ReplicationTimeoutType	ELECTION_TIMEOUT The timeout period for an election.
static ReplicationTimeoutType	FULL_ELECTION_TIMEOUT An optional configuration timeout period to wait for full election participation the first time the replication group finds a master.
static ReplicationTimeoutType	HEARTBEAT_MONITOR The amount of time the replication manager, running at a client site, waits for some message activity on the connection from the master (heartbeats or other messages) before concluding that the connection has been lost.
static ReplicationTimeoutType	HEARTBEAT_SEND The frequency at which the replication manager, running at a master site, broadcasts a heartbeat message in an otherwise idle system.

Field Detail

ACK_TIMEOUT

public static final ReplicationTimeoutType ACK_TIMEOUT

Configure the amount of time the replication manager's transport function waits to collect enough acknowledgments from replication group clients, before giving up and returning a failure indication.

CHECKPOINT_DELAY

public static final ReplicationTimeoutType CHECKPOINT_DELAY

Configure the amount of time the replication manager will delay between completing a checkpoint and writing a checkpoint record into the log. This delay allows clients to complete their own checkpoints before the master requires completion of them. The default is 30 seconds.

CONNECTION_RETRY

public static final ReplicationTimeoutType CONNECTION_RETRY

Configure the amount of time the replication manager will wait before trying to re-establish a connection to another site after a communication failure.

ELECTION_TIMEOUT

public static final ReplicationTimeoutType ELECTION_TIMEOUT

The timeout period for an election.

ELECTION_RETRY

public static final ReplicationTimeoutType ELECTION_RETRY

Configure the amount of time the replication manager will wait before retrying a failed election.

HEARTBEAT_MONITOR

public static final ReplicationTimeoutType HEARTBEAT_MONITOR

The amount of time the replication manager, running at a client site, waits for some message activity on the connection from the master (heartbeats or other messages) before concluding that the connection has been lost. When 0 (the default), no monitoring is performed.

HEARTBEAT_SEND

public static final ReplicationTimeoutType HEARTBEAT_SEND

The frequency at which the replication manager, running at a master site, broadcasts a heartbeat message in an otherwise idle system. When 0 (the default), no heartbeat messages will be sent.

FULL_ELECTION_TIMEOUT

public static final ReplicationTimeoutType FULL_ELECTION_TIMEOUT

An optional configuration timeout period to wait for full election participation the first time the replication group finds a master. By default this option is turned off and normal election timeouts are used. (See the Elections section in the Berkeley DB Reference Guide for more information.)
