摘要： A sequence of processing transactions operating on a cached data set, which depend on each other because they operate on the same items of data from the data set. The transactions are saved until the master copy of the data becomes available. The transactions are played back against the master copy until one of the played back transactions fails because another transaction which operated on the same items of data but against a separate cached copy and originating from another application, was successfully played back on the master copy at an earlier time. At this point, all subsequent transactions which depended on the failing transaction are rolled back on the cached copy (with appropriate failure reports generated) and activity resumes from there. “Chained” (optimistic) transactions can therefore be applied to cached data and can be allowed to progress by recording their dependencies so they can be undone when required.

摘要： A method and system for distribution of information are provided in a publish and subscribe system in which a publisher application transmits a message (210, 310) to one or more subscribing applications (208, 308) via a messaging infrastructure. The method includes receiving (203, 303) a message at a subscribing system (202, 302) and generating an event by the subscribing system to allow access to the message (210, 310) by a subscribing application (208, 308) at a reveal time (211, 311). A counting means (205, 305) on the subscribing system determines when it is the reveal time (211, 311) and the event is triggered at the reveal time (211, 311). A message (210) has a reveal time (211, 311) common to the one or more subscribing applications (208, 308).

摘要翻译： 在发布和订阅系统中提供了用于分发信息的方法和系统，其中发布者应用程序通过消息传递基础设施向一个或多个订阅应用程序（208,308）发送消息（210,310）。 该方法包括在订阅系统（202,302）处接收（203,303）消息并且由订阅系统生成事件以允许订阅应用程序（208,308）以 揭示时间（211,311）。 订阅系统上的计数装置（205,305）确定何时是显示时间（211,311），并且在显示时间（211,311）触发事件。 消息（210）具有对于一个或多个订阅应用（208,308）共同的显示时间（211,311）。
