  • Synchronization using commitment
    Patent number: 6601069
    Abstract: A method of sharing a file object among a plurality of competing processes, the file object having a content that at least one competing process may need to adjust so that the file is suitable for the operating environment of the competing process. To help make an adjustment, the file object includes a state attribute that indicates whether or not the file is committed and whether the file is in an inconsistent state. If the file contents are suitable for the specific process and the file object is not committed, the file can be committed by the specific process. If the file contents are not suitable for the specific process and the file object is not committed, the file is locked, set to inconsistent, adjusted, committed by the specific process and then unlocked. This process improves concurrency of the competing processes and reduces message overhead.
