Abstract
A system is disclosed in which recovery scenarios in a system for global transaction processing are testable with application programs. A client application program initiates a global transaction that results in multiple service requests to be processed by one or more server application programs. After processing of the service requests is complete, the client application program issues a selected test command that partially performs two-phase commit processing according to a predetermined recovery scenario. Recovery processing is initiated to recover the databases affected by the global transaction Control and status information are then returned to the client application program. After recovery processing is complete, the databases are compared to the expected states according the recovery scenario.
