摘要： A highly available, high-performance memory queue. Locking of the queue is minimized in order to provide a highly available queue and to improve performance of the queue. Multiple updates of the queue can occur under a single lock. Further, messages of the queue are persistent. A time-initiated checkpointing process, as well as the storing of message information on a recovery log, ensures the persistence of the queue messages.

摘要： A plurality of batch lists are maintained by a channel in order to improve the efficiency of the channel in performing messaging between a sender and a receiver. For example, a Next Batch list is used to prefetch messages to be sent to the receiver from the sender; a Current Batch list includes the messages currently being transmitted to the receiver or waiting confirmation; and an Acknowledged Batch List includes the messages confirmed by the receiver. This allows the functions of prefetching messages, sending messages and deleting confirmed messages to be performed in parallel.

摘要： When a processor becomes inactive, queues resident in the memory of that processor become inaccessible. Thus, in order to access those queues, an active processor takes over ownership of one or more of the inaccessible queues. Each queue may be rebuilt prior to its take over to ensure that it has up-to-date information.
摘要翻译：当处理器变得不活动时，驻留在该处理器的存储器中的队列变得不可访问。因此，为了访问这些队列，活动处理器占用一个或多个不可访问队列的所有权。每个队列可能在其接管之前重建，以确保它具有最新信息。

摘要： Memory resident queues are monitored at predefined time intervals. When the monitoring indicates that a particular queue is not being serviced at a desired level, then action is taken to sweep one or more messages from the queue. The sweeping of the messages frees up system resources associated with the messages, thus allowing other tasks to be serviced. If, after the sweeping, it is determined that the queue can handle additional messages, then one or more messages are placed back on the queue.

摘要： A method and apparatus for switching messages from a primary message channel to a secondary message channel in a message queuing system in which messages are placed in a first transmission queue of a local system for transmission to a remote system via a primary message channel. A local queue manager continuously checks to see whether a high water mark has been reached in the first transmission queue, indicating an apparent failure in the primary message channel. On determining such an apparent failure in the primary message channel, the queue manager determines whether the secondary message channel is associated with the first transmission queue. If so, the queue manager activates the secondary message channel to serve said first transmission queue. If, on the other hand, the secondary message channel is associated with another transmission queue, the queue manager transfers messages already in the first queue to the other queue and redirects any new messages intended for the first queue to the other queue. If the other transmission queue was previously empty, the secondary message channel is activated by a trigger to serve the other queue.
摘要翻译：一种用于将消息从主消息信道切换到消息队列系统中的辅助消息信道的方法和装置，其中消息被放置在本地系统的第一传输队列中，以经由主消息信道传输到远程系统。本地队列管理器持续检查在第一个传输队列中是否达到高水位标记，表明主消息通道明显失败。在确定主消息信道中的这种明显故障时，队列管理器确定辅助消息信道是否与第一传输队列相关联。如果是，则队列管理器激活辅助消息信道以服务于所述第一传输队列。另一方面，如果辅助消息信道与另一传输队列相关联，则队列管理器将已经在第一队列中的消息传送到另一个队列，并且将用于第一队列的任何新消息重定向到另一队列。如果另一个传输队列以前是空的，则辅助消息通道由触发器激活以提供其他队列。

摘要： A structure and method is provided for optimizing memory resources, by establishing a history file for recording data processing criterion. The history file is then recorded in a first memory. Information either stored in the first memory or scheduled to be stored in the first memory can then be selectively reallocated and stored in an alternate memory. All or portions of the reallocated information can then be restored back to the first memory subsequently, with reference to the history file.

摘要： Techniques for replicating modified data to a hierarchical database. A first list comprises records included in a set of records before at least one modification thereto. A second list comprises records included in the set of records after the at least one modification thereto. For each pre-modification record included in the first list and each post-modification record included in the second list having equal identifying values, a target record at the database and having a matching identifying value is modified. Specifically, if both records include corresponding indexes, information about a structure pointed to by the pre-modification record is removed from an index included in the target record, and information about a structure pointed to by the post-modification record is added to the index. If neither record includes an index, the target record is modified to contain at least one changed value included in the post-modification record.
摘要翻译：将修改的数据复制到分层数据库的技术。第一列表包括在至少一个修改之前包括在一组记录中的记录。第二列表包括在对其进行至少一个修改之后的记录集中包括的记录。对于包括在第一列表中的每个预修改记录和包括在具有相同标识值的第二列表中的每个修改后记录，修改了数据库处的具有匹配标识值的目标记录。具体来说，如果两个记录都包含相应的索引，则从预定修改记录指向的结构的信息从包含在目标记录中的索引中移除，并且将修改后记录指向的结构的信息添加到索引中。如果两个记录都不包括索引，则目标记录被修改为包含修改后记录中包含的至少一个更改的值。
