Title:
TRANSACTIONAL UPDATING IN DYNAMIC DISTRIBUTED WORKLOADS
Document Type and Number:
WIPO Patent Application WO/2011/083056
Kind Code:
A3
Abstract:
A workload manager is operable with a distributed transaction processor having a plurality of processing regions (110, 120) and comprises: a transaction initiator region (100) for initiating a transaction; a transaction router component (170) 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 characterised 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.
