Abstract
The present invention is a scalar quantity implemented as a process-pair resource manager. The process-pair implementation includes a concurrent aspect and a serial aspect. The concurrent aspect provides an object-like interface to the scalar quantity. Threads and processes access the scalar quantity by passing messages to the concurrent aspect. The concurrent aspect adds a description of each message as well as the result of processing each message to a transaction record. At the conclusion of a transaction, the concurrent aspect passes the transaction record to the serial aspect. The serial aspect then replays the transaction, using the transaction record. If the replay of the transaction is consistent with the transaction as recorded in the transaction record, the serial aspect sends a message to the concurrent aspect voting to commit the transaction. In turn, the concurrent aspect sends a message to the transaction manager forwarding the commit message. In the event of process, processor, communication or system failure, the scalar quantity is always recoverable to reflect all, and only, committed transactions.
