A transaction is unit of activity within which multiple updates to resources can be made atomic (as an indivisible unit of work) such that all or none of the updates are made permanent. WAS supports the coordination of resource managers and participates in distributed global transactions with transaction managers that support specific protocols. Resource managers that offer transaction support can be categorized into those that support two-phase coordination and those that support only one-phase coordination.
