ReplicationConfig Properties

BerkeleyDB

The ReplicationConfig type exposes the following members.

Properties

  NameDescription
AckTimeout
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. The default wait time is 1 second.
CheckpointDelay
The amount of time a master site will delay between completing a checkpoint and writing a checkpoint record into the log.
ClockskewFast
The value, relative to ClockskewSlow, of the fastest clock in the group of sites.
ClockskewSlow
The value of the slowest clock in the group of sites.
ConnectionRetry
The amount of time the replication manager will wait before trying to re-establish a connection to another site after a communication failure. The default wait time is 30 seconds.
ElectionRetry
Configure the amount of time the replication manager will wait before retrying a failed election. The default wait time is 10 seconds.
ElectionTimeout
The timeout period for an election. The default timeout is 2 seconds.
FullElectionTimeout
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.)
HeartbeatMonitor
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.
HeartbeatSend
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.
LeaseTimeout
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 method must be called prior to calling RepStartClient()()() or RepStartMaster()()().
NSites
The total number of sites in the replication group.
Priority
The database environment's priority in replication group elections. A special value of 0 indicates that this environment cannot be a replication group master. If not configured, then a default value of 100 is used.
RetransmissionRequestMax
The maximum number of microseconds a client waits before requesting retransmission.
RetransmissionRequestMin
The minimum number of microseconds a client waits before requesting retransmission.
TransmitLimitBytes
The bytes component of the byte-count limit on the amount of data that will be transmitted from a site in response to a single message processed by RepProcessMessage(DatabaseEntry, DatabaseEntry, Int32).
TransmitLimitGBytes
The gigabytes component of the byte-count limit on the amount of data that will be transmitted from a site in response to a single message processed by RepProcessMessage(DatabaseEntry, DatabaseEntry, Int32).
