## Class ReplicationTimeoutType

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

-     public final class ReplicationTimeoutType
      extends java.lang.Object

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

  The class is used in the `Environment.setReplicationTimeout` method.

- - ### Field Summary

    Fields
    Modifier and Type | Field | Description
    --- | --- | ---
    `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.
    `static ReplicationTimeoutType` | `LEASE_TIMEOUT` | Configure the amount of time a client grants its master lease to a master.
    `static ReplicationTimeoutType` | `WRITE_FORWARD_TIMEOUT` | Configure the amount of time a Replication Manager client waits for a response from a forwarded write operation before returning a failure indication.

- - ### 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.)

    - #### LEASE_TIMEOUT

          public static final ReplicationTimeoutType LEASE_TIMEOUT

      Configure the amount of time a client grants its master lease to a master. When using master leases all sites in a replication group must use the same lease timeout value. There is no default value. If leases are desired, this timeout must be configured prior to calling `Environment.startReplication`.

    - #### WRITE_FORWARD_TIMEOUT

          public static final ReplicationTimeoutType WRITE_FORWARD_TIMEOUT

      Configure the amount of time a Replication Manager client waits for a response from a forwarded write operation before returning a failure indication. The default value is 5 seconds.

  - ### Method Detail

    - #### toString

          public java.lang.String toString()

      Overrides:
        `toString` in class `java.lang.Object`
