  • Cross-system process control framework
    Patent number: 11650974
    Abstract: Methods and apparatus are disclosed for controlling distributed software applications implementing asynchronous replication of shared data objects. Each shared data object has a distinct token. A token has respective states (active or inactive) at each computing system sharing the data object. At most one computing system can have the token active at any time; possessing an active token allows a computing system to update the shared data object. Counters maintain state across the computing systems, and semantic checks specific to a class of data objects (or, a single object) ensure consistency of updates across computing systems. Token activation requests and update replication requests are supported. Participating computing systems can have asymmetric or symmetric roles.
