Transactional updating in dynamic distributed workloads

A method for operating a workload manager with a distributed transaction processor having a plurality of processing regions, comprising:

• initiating a transaction by a transaction initiator region;
• routing an initiated transaction by a transaction router component to one of said plurality of processing regions;
• restricting transaction routing operations by an affinity controller component to maintain affinities;
• and
• activating an affinity responsive to completion of a recoverable data operation at said one of said plurality of processing regions.

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 affinity between a unit of work 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.

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 affinity between a unit of work 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.
