Controls whether the DGC automatically requests iteration initiation once a threshold is passed. The default is true.

Specifies the amount by which the number of exports may grow after an iteration concludes before a new iteration is automatically requested. The default is 100.

Specifies the maximum number of seconds one DGC iteration can take. This is used to prevent iterations lasting indefinitely and to detect failure. If an iteration is not completed inside this time period, it is assumed to have failed and each participant enacts its failure recovery mechanisms. The setting of this parameter must allow for normal iteration completion times which depend on the number of participating spaces and the communications characteristics. The default setting is 120 seconds.

Set the iterationTimeout well in excess of twice the messageArrivalDelay. If this is not done, iterations may timeout and fail while DGC objects are still delayed awaiting message arrival. It is your responsibility to ensure that these options are set correctly.

Specifies the time (in milliseconds) to wait for messages before going to the next phase of the DGC algorithm. Delaying in order to await message arrival from other DGC participants at various points in the algorithm can reduce the number of messages required to complete the iteration. A rough heuristic to use in setting this parameter is: (average message time) * 5. Note that this delay is only an optimization; it does not affect the correctness or efficiency of the algorithm. The default is 1501 milliseconds, which has been determined by tests to be the optimum delay.

Specifies the number of times to try to register with the coordinator during startup. The value must be a positive integer. The default setting is 6.

Specifies the total time, in seconds, allowed for each registration attempt. If registration succeeds, then startup returns immediately. Otherwise, if a response has not been received in the time set by this option, the attempt is aborted and retried (if allowed by the registrationAttempts option). The integer value of this option must be >= 1. The default setting is 10 seconds.
