A method, system, and computer program product stores transaction state information in application server process cluster information, eliminating transaction state logging and reducing the processing and communications expense that is necessary for transaction processing. A method of performing transaction execution comprises the steps of beginning execution of a transaction using a first process, storing a state of execution of the transaction in user state information included in cluster information accessible to a plurality of processes including the first process, switching a context from the first process to a second process that is one of the plurality of processes having access to the user state information included in the cluster information, and continuing execution of the transaction using the second process and the user state information included in the cluster information. The step of switching the context from the first process to the second process may be performed if the first process fails.
