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.

First claim

The invention claimed is:

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.

2. The method of claim 1 , wherein
the recoverable data operation is a recoverable modification to a resource accessed by the processing region to which the initiated transaction is routed.

3. A computer hardware system configured to operate a workload manager with a distributed transaction processor having a plurality of regions, comprising:
at least one hardware processor configured to perform and/or initiate:
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.

4. The system of claim 3 , wherein
the recoverable data operation is a recoverable modification to a resource accessed by the processing region to which the initiated transaction is routed.
