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： 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： 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： 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： Apparatus and process for managing shared, distributed locks in a multiprocessing complex. The manager operates using a partitionable lock space with logical processor connection. Logically connected processors are subject to validation and disconnection due to failure. The locks synchronize data access to identifiable subunits of DASD. Denied lock requests are queued for servicing when the lock becomes available. Lock partitions are used to speed DASD to DASD copying without halting processing on the first DASD. A special partition is assigned to the copy task and the processors writing to the DASD can determine copy status with a single read or test. Operations requiring multilateral agreement of processors, such as rebuilding locks or moving locks, are protected by fencing any nonresponsive processor. A special queue partition is designated for master/slave control point designation. All processors contend for the master lock and losing contenders are queue. Queuing provides automatic fallback in case of a failing processor.

摘要： The present invention provides for a computer program product and device including instructions executable by a digital processing apparatus for conducting a high-performance locking facility. At first multiple requests for locking operations are processed and received simultaneously and their lock names and lock states are recorded in entry records of a lock table based on the requests. Next high-speed searching of any particular lock entry in this table is performed followed. The table can be altered and modified at this time as well accordingly depending upon lock status that is being processed. Finally an appropriate response is generated and the status of the lock state is provided to those requesting the lock.

摘要： A method and system are disclosed for efficiently managing task memory in a multi-tasking data processing system having a processor for processing multiple tasks, task memory associated with each task, main system memory and multiple data records stored within direct access storage. A data record is copied from direct access storage into a buffer in main system memory in response to an access of that data record by a particular task. A buffer within that task's virtual memory is then mapped to the data record and a write protect bit is associated with the task memory buffer. Thereafter, any attempt to store data into the buffer will temporarily halt processing of the task until a copy of the data record is written to a second buffer. Task processing is then resumed, after modifying the task's page table to reference the second buffer, and the task is then permitted to store data within the second buffer. In this manner, a second buffer copy of the data record is only created in response to an attempted modification of the data record, thereby minimizing the processor and memory assets required to manage data records in a multi-tasking data processing system.
摘要翻译：公开了一种用于在具有用于处理多个任务的处理器，与每个任务相关联的任务存储器，主系统存储器和存储在直接访问存储器内的多个数据记录的多任务数据处理系统中有效管理任务存储器的方法和系统。响应于特定任务对该数据记录的访问，将数据记录从直接访问存储器复制到主系统存储器中的缓冲器中。然后将该任务的虚拟内存中的缓冲区映射到数据记录，并将写保护位与任务存储器缓冲区相关联。此后，将数据存储到缓冲器中的任何尝试将暂时停止任务的处理，直到将数据记录的副本写入第二缓冲器。然后在修改任务的页表以引用第二缓冲区之后恢复任务处理，然后任务被允许在第二缓冲器内存储数据。以这种方式，数据记录的第二缓冲器拷贝仅响应于对数据记录的尝试修改创建，从而最小化在多任务数据处理系统中管理数据记录所需的处理器和存储器资产。
