Abstract
An indication is provided to a transaction participant as part of a message originating from a transaction coordinator. The message indicates that the transaction coordinator supports a heuristic response. The transaction coordinator coordinates commitment of transactions as requested by an application in response to a determination by the transaction participant of a heuristic outcome. Heuristic outcomes include situations where transaction participants determine they are unable to honor transactional prior prepared commitments made to the transaction coordinator during first prepare phases of two-phase commits associated with the transactions. The heuristic response is received from the transaction participant in association with a transaction coordinated by the transaction coordinator and indicates that the transaction participant is unable to honor a transactional prior prepared commitment made by the transaction participant during a first prepare phase of a two-phase commit associated with the transaction coordinated by the transaction coordinator as requested by the application.
