Abstract: A method and system for managing transactions. At least one resource manager (RM) for managing changes to respective system resources of a data processing system is provided. A resource manager coordinator (RMC) for coordinating commit-backout activities of the at least one resource manager is provided. The resource manager coordinator (RMC) is hosted by the data processing system. The data processing system receives a business service request from a remote computer system to perform a task. The task includes compliant processes complying with a commit/backout protocol and non-compliant processes not complying with a commit/backout protocol. The compliant processes are running on the data processing system and the non-compliant processes are running on a counterpart processing system that is coupled to the data processing system by a labile link.

Abstract: A data processing system comprises at least one resource manager (RM) for managing changes to respective system resources in accordance to a commit/backout protocol, and a resource manager coordinator (RMC) for coordinating the commit/backout activities of the at least one resource manager. A process resource manager (ERM) is provided, coordinated by the resource manager coordinator according to the commit/backout protocol, for managing the execution of non-compliant processes not complying with the commit/backout protocol. The process resource manager automatically determines, upon receipt of a backout request, a sequence of compensation actions to be performed to backout actions performed during the execution of the secondary non-compliant processes, and managing the execution of said compensation actions.
