DESCRIPTION
The process of creating Byzantine fault-tolerant session across a pool
pf participating processors is complex. The CreateReplicasOnServers
class implements the necessary logic.
METHODS
Standard.CreateReplicasOnServers:create
CreateReplicasOnServers:create()
Method Description
See initialize.
Standard.CreateReplicasOnServers:initialize
CreateReplicasOnServers:initialize(string serverPoolName, int32 faultsToTolerate, string stateClassName, string stateObjectName, any additionalStateVarArgs, string proxyClassName, string proxyObjectName, any additionalProxyArgs)
Method Description
The initialize method takes a large number of arguments, which
is an unfortunate consequence of the complexity of the underlying task.
- serverPoolName
- identifies the potential pool of servers which should be used to support
the Byzantine fault-tolerant transaction
- faultsToTolerate
- indicates how many simultaneous faults must be tolerated; the total
number of servers required is dependents on this value and is calculated
as 3 * faultsTolerates + 1.
- stateClassName
- identifies the name of the class that implements the server-side
implementation of the state variable.
- stateObjectName
- specifies the service name which will be an alias for the
individual state variables.
- additionalStateVarArgs
- any arguments that need to be provided to the create method
of the class denoted by stateClassName.
- proxyClassName
- identifies the name of the class that implements the proxy.
- proxyObjectName
- specifies the service name which will be an alias for the
individual proxy variables.
- additionalProxyArgs
- any arguments that need to be provided to the create method
of the class denoted by proxyClassName.
Standard.CreateReplicasOnServers:getNeededReplicaCount
CreateReplicasOnServers:getNeededReplicaCount()
Method Description
Returns the count of the number of replicas that could not be activated.
A value of 0 corresponds to success and a value of -1 indicates no
initialization has yet been attempted.
Standard.CreateReplicasOnServers:getReplicaList
CreateReplicasOnServers:getReplicaList()
Method Description
Returns an array of object Ids identifying each of the replicas.
