An object of ReplicaClientProxy performs the actions required to initiate Byzantine fault-tolerant transactions.



ReplicaClientProxy:create(array replicaList, optional string proxyObjName, optional int32 id)

Method Description

See initialize.


ReplicaClientProxy:initialize(array replicaList, optional string proxyObjName, optional int32 id)

Method Description


ReplicaClientProxy:raiseWaitLimit(int32 faultsToInitiallyTolerate)

Method Description

Transaction results are returned when there are sufficient valid responses. The lower bound is faultLimit + 1 and the upperbound is replicaTotal. Normally, correct results are returned as soon as feasible. This behavior can be altered so that a larger number of verified results will be required before a response is sent back. This will always result in increased latency. If the limit is increased too high and a fault occurs, an unnecessary delay can also be introduced waiting for a correct response that never arrives.

Return Value

Returns the new limit.


ReplicaClientProxy:setNextRequestID(int32 id)

Method Description

Return Value

The Id to be allocated to the next request.
