Abstract
The present invention extends to methods, systems, data structures, and computer program products for maintaining correct transaction results when transaction management configurations change. An intermediate transaction manager is transparently interposed between one or more resource managers and a plurality of transaction managers. The intermediate transaction manager multiplexes and intercepts calls and notifications between the one or more resource managers and the plurality of transaction managers. The intermediate transaction manager is configured to wrap recovery cookies with transaction manager type information and identity information that identify transaction managers. The information can be used to re-attach to the transaction manager to recover the correct outcome of the transaction. The intermediate transaction manager can also intercept recovery-complete calls directed to a specific transaction manager and send the recovery-complete call to each of the plurality of transaction managers. Resource managers can receive, store, and send wrapped recovery cookies.
