Transactional updating in dynamic distributed workloads
First Claim
1. A method of operating a workload manager with a distributed transaction processor having a plurality of regions, comprising:
- initiating a transaction;
routing the initiated transaction to one of the plurality of processing regions;
declaring a provisional and non-activated affinity between a unit of work associated with the initiated transaction and the processing region to which the initiated transaction is routed;
performing, by the processing region to which the initiated transaction is routed, a recoverable data operation; and
activating, based upon completion of the recoverable data operation, the provisional affinity.

Abstract
A workload manager is operable with a distributed transaction processor having a plurality of processing regions and comprises: a transaction initiator region for initiating a transaction; a transaction router component for routing an initiated transaction to one of the plurality of processing regions; an affinity controller component for restricting transaction routing operations to maintain affinities; the affinity controller component characterized in comprising a unit of work affinity component operable with a resource manager at the one of the plurality of processing regions to activate an affinity responsive to completion of a recoverable data operation at the one of the plurality of processing regions.
