Abstract: A Data Synchronization and Failover Management (DSFM) system monitors simultaneous execution of non-identical instances of a software application and may label as a particular result of the software application the earliest output corresponding to that result produced by one of the instances. The DSFM may label one of the instances as a primary instance and the other instances as secondary instances and, if the primary instance fails, may re-label one of the secondary instances that computed all of the operations associated with the last result produced prior to the failure of the primary instance, as a new primary instance.

Abstract: In a system for executing transaction requests, a received request for a transaction in an item is delayed prior to matching that request with another request for transaction in that item by a delay based on a communication delay and/or a processing delay. The communication delay represents the time required to receive updated information about the item and the processing delay represents the time required to compute an updated item price using the received updated information.

Abstract: Embodiments of the Message Retransmission Mechanism Apparatuses, Methods and Systems (“MRM”) transform application requests for message journals via MRM components into expedited access to segmented message streams. In one implementation, the MRM may obtain message journal of messages written by applications during system operations and divide up the message obtained from the complete message journal into message segments. In some implementations, the MRM may provide recovering applications access to said message segments for expedited message consumption.
