    摘要： The present invention extends to methods, systems, and computer program products for maintaining message state at a message log. Messages are accumulated at a message log in accordance with a message retention policy. Any of a variety of message capture assurances can be used when capturing a message from a message producer within a message log. A message becomes visible to message consumers after the outcome of writing the message is known (either failure or success). Messages are requested using (e.g., monotonically increasing) sequence numbers. Messages are also dropped from the message log in accordance with the message retention policy.

    摘要： The setting up of a circular log implementation to be able to detect amnesia in a circular log, and to the determination of whether or not amnesia has occurred in such a circular log. Upon detecting a checkpoint trigger, information is preserved sufficient to detect whether or not the removed records ever existed in the circular log. If a request for information from a record were subsequently to be received by the circular log implementation, and if the record was not actually in the circular log, the preserved information could then be consulted to see if it indicates that the record had once existed in the circular log. If the information indicates that the record had once existed in the circular log, then amnesia has not occurred. If the information does not indicate that the record had once existed in the circular log, then amnesia has occurred. Accordingly, amnesia detection is made possible even in a complicated circular log implementation.

    摘要： Log file amnesia detection is accomplished by associating a unique identifier with each record in a log file, where each record receives a unique log sequence number. Multiple time intervals are associated with the log file with different events triggering the beginning of a new time interval. The log file implementation marks the beginnings of these multiple time intervals with a unique identifier. Every time an event occurs that triggers a new time interval a new unique identifier is generated. This unique identifier will be associated with the records in the log file that are created thereafter until the next unique identifier gets generated, marking the beginning of a next time interval. Log file amnesia can be identified when a log client requests information about a record and then comparing the unique identifier and log sequence number of the record with all records in the log file.

    摘要翻译： 日志文件遗忘检测通过将唯一标识符与日志文件中的每个记录相关联来完成，其中每个记录接收唯一的日志序列号。 多个时间间隔与日志文件相关联，具有触发新时间间隔开始的不同事件。 日志文件实现标记了具有唯一标识符的这些多个时间间隔的开始。 每次发生触发新时间间隔的事件时，都会生成新的唯一标识符。 此唯一标识符将与之后创建的日志文件中的记录相关联，直到生成下一个唯一标识符，标记下一个时间间隔的开始。 当日志客户端请求有关记录的信息，然后将记录的唯一标识符和日志序列号与日志文件中的所有记录进行比较时，可以识别日志文件遗忘。

    摘要： Systems and methods in accordance with the present invention allow for messages to be delivered from one application to another over a network in discrete groupings or communication sessions. For example, a sending computer system sends a group of related messages to a queue at a recipient computer system. The recipient computer system identifies that the messages of the group are related, and initiates a session-oriented communication channel. The recipient computer passes the group of messages to an appropriate application, and opens a different, new session-oriented communication channel for a new group of messages that are not necessarily related to the first group of messages. In one implementation, an order identifier in each of the received messages instructs the recipient computer system on what order, if any, the messages in a group are to be processed by the specific application.
