  • Patent number: 5884327
    Abstract: The system, method, and program of this invention allows a two-phase commit protocol to work properly, even when the client acting as the coordinator does not have a log to record two-phase state information. In a preferred embodiment, the client in a client/server distributed transaction processing system is a personal computer. The client, without a recovery log, acts as a coordinator of a commit process. The coordinator migrates, i.e., passes, responsibility for resynchronization, and any associated logging requirement, to a server, e.g., to any of the connected relational database management system (RDBMS) servers, which is a participant in the transaction. The server uses its own recovery log for use in satisfying the logging requirement.
