摘要： Dynamically allocated memory is managed in real-time. This real-time management capability enables an invalid access of the dynamically allocated memory to be detected at the time the invalid access occurs, rather than at some later point in time. This real-time management capability can be dynamically activated/deactivated on a per process basis.
摘要翻译：动态分配的内存被实时管理。这种实时管理能力使得在无效访问发生时，而不是在稍后的时间点上动态分配的存储器被无效访问。可以在每个进程的基础上动态激活/停用该实时管理功能。

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： 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 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： A method for implementing process thread locking operations includes defining a lock structure having data fields that include a process thread identifier and a shared object identifier that uniquely identifies a shared object subject to lock operations. The method also includes using the lock structure to build a lock table. The lock table includes lock structures for each process thread in the process and is searchable in response to a request for a shared object from a calling thread. The method also includes determining a lock status of the shared object. The lock status indicates whether the shared object is currently locked by the calling process thread. In response to the lock status, the method includes obtaining a lock on the shared object when the request is for a lock, and releasing a lock on the shared object when the request is to unlock the shared object
摘要翻译：用于实现过程线程锁定操作的方法包括定义具有数据字段的锁结构，该数据字段包括过程线程标识符和唯一地标识被锁定操作的共享对象的共享对象标识符。该方法还包括使用锁结构来构建锁表。锁表包括在进程中的每个进程线程的锁结构，并可响应于来自调用线程的共享对象的请求而被搜索。该方法还包括确定共享对象的锁定状态。锁定状态指示共享对象当前是否被调用进程线程锁定。响应于锁定状态，该方法包括当请求用于锁定时获得共享对象上的锁定，并且当请求解锁共享对象时释放共享对象上的锁定
