Abstract
A transaction manager virtualization layer is provided for supporting multiple active transaction managers in a cluster or node. By virtualizing the transaction managers, applications and services are enabled to migrate across cluster nodes or even outside a cluster that includes relevant recovery mechanisms for transactions that are not completed at the time of migration. Multiple implementations of a transaction manager may be enabled to run side-by-side in a node or cluster allowing a rolling upgrade of transaction managers in clusters.
