An exemplary embodiment of the present invention is a method for affinity free restart of a resource manager in a multi-system environment. The method begins when a restart request is received from a first resource manager on a first system in the multi-system environment. The first resource manager is associated with an incomplete transaction. Next, a distributed transaction unit of recovery structure is built for the incomplete transaction. Then, the distributed transaction unit of recovery structure is sent to a transaction manager for restart processing. The restart process includes restarting the first resource manager on the first system. The restart process also includes restarting a second resource manager on a second system in the multi-system environment if the incomplete transaction is associated with the second resource manager. The second system is a different system in the multi-system environment than the first system and the second resource manager previously had a node in common with the first resource manager. Additional embodiments include a system and storage medium for affinity free restart of a resource manager in a multi-system environment.
