Good Afternoon All
I am seeking a definition and any information on the term 'Heurisitic
completion'
Come on Martin, everybody knows what heuristic completion is:
Heuristic completion is when a transaction attempts to complete, and one
of its participating Resources makes a heuristic decision during the
completion stage. A heuristic decision is a unilateral decision made by
one or more Resources to commit or rollback updates--without regard for
the outcome determined by the ITS Transaction Service.
Heuristic decisions typically only occur during unusual circumstances
that prevent normal processing--such as a network failure, or if the
Coordinator does not complete the two-phase commit process in a timely
manner. When a heuristic decision is made, there is a risk that the
decision may differ from the outcome determined by the ITS Transaction
Service, resulting in a loss of data integrity.
