摘要： Example methods and apparatus to manage object locks are disclosed. A disclosed example method includes receiving an object lock request from a processor, the lock request associated with object lock code to lock an object, and generating object lock-bypass code based on a type of the processor, the object lock-bypass code to execute in a managed runtime in response to receiving the object lock request. The example method also includes identifying a type of instruction set architecture (ISA) associated with the processor, invoking a checkpoint instruction for the processor based on the identified ISA, suspending the object lock code from executing and executing target code when the object is uncontended, and allowing the object lock code to execute when the object is contended.

摘要： Improved methods for providing recoverable workflow of complex and/or risk-prone workflows in a computer system or computer network include segmenting such workflows into sub-processes, associating a checkpoint with the end of each sub-process, and determining whether processing of each sub-process was successful. If so, a set of parameters is stored at each checkpoint before processing the next sub-process, but otherwise processing of the failed sub-process is retried, using the parameter set stored at the previous checkpoint. In one embodiment, the methods are implemented by a certified messaging capability that guarantees delivery of any message. In the event a hardware or software failure occurs during a sub-process execution, the certified messaging capability returns a failure indication, so that execution of the failed sub-process can be reinitiated. Improved computers and computer networks for providing recoverable workflow are also described.
摘要翻译：用于在计算机系统或计算机网络中提供复杂和/或易冒险的工作流的可恢复工作流的改进方法包括将这样的工作流分割成子过程，将检查点与每个子过程的结束相关联，以及确定是否处理每个子程序成功。如果是这样，在处理下一个子进程之前，在每个检查点存储一组参数，但是使用存储在先前检查点的参数集来重试失败的子进程的处理。在一个实施例中，这些方法通过确保传送任何消息的经认证的消息传递功能实现。在子进程执行期间发生硬件或软件故障的情况下，经认证的消息传递功能将返回失败指示，以便可以重新启动失败的子进程的执行。还描述了用于提供可恢复工作流的改进的计算机和计算机网络。
