The disclosed embodiments relate to creation and dissemination of unique identifiers, i.e. tokens, for use in communication of messages from a transaction processing system, to participants therein whereby messages, or at least a portion of the content thereof, indicative of a response to a request, to transact or modify a prior transaction, are consolidated, or otherwise combined, with the corresponding directed reporting messages communicated to the particular participants participating in the reported transaction while preserving the anonymity of those participants to which messages are particularly directed. The identifiers are structured so as to facilitate rapid validation and dissemination while eliminating the ability to associate any given identifier, or set thereof, with a participant.

Tokens, and the use thereof, for public distribution of messages having a private association with a subset of the message recipients

A computer implemented method for providing fault tolerance to a plurality of machines includes determining an aggregate load for each surviving machine of a plurality of surviving machines; calculating a recovery load of one or more orphaned jobs resulting from a terminating event; and selecting to recover and perform one or more of the orphaned jobs, by one or more of the surviving machines, based upon (i) the recovery load of the one or more orphaned jobs; (ii) the job load of the one or more orphaned jobs; and (iii) the aggregate loads of the surviving machines.

Clustered fault tolerance systems and methods using load-based failover

A computer implemented method for providing fault tolerance to a plurality of instances in a system including a plurality of surviving instances includes: determining, for each of the surviving instances, an aggregate load by: retrieving a job load of each job assigned to the respective surviving instance; and summing the job loads of all of the jobs assigned to the respective surviving instance; and selecting to recover and perform, by one of the surviving instances, an orphaned job based upon the aggregate loads of the surviving instances.
