摘要： For use with an active database stored in volatile memory for direct revision thereof, the active database having multiple checkpoints and a stable log, having a tail stored in the volatile memory, for tracking revisions to the active database to allow corresponding revisions to be made to the multiple checkpoints, the active database subject to corruption, a system for, and method of, restoring the active database and a computer system containing the same. The system includes: (1) a checkpoint determination controller that determines which of the multiple checkpoints is a most recently completed checkpoint and copies the most recently completed checkpoint to the volatile memory to serve as an unrevised database for reconstructing the active database and (2) a revision application controller that retrieves selected ones of the revisions from the stable log and the tail and applies the revisions to the unrevised database thereby to restore the active database. In an advantageous embodiment, the applied revisions include log records at an operation level (lower level of abstration than transactions), and the revision application controller, using memory locks while restoring the active database, releases ones of the memory locks as a function of applying ones of the log records.

摘要： A method for recovering spin locks in a system having one or more processes capable of accessing a shared resource, the system providing a lock indicating exclusive access to the shared resource by a single process and enabling one or more processes to repeatedly attempt to gain access to the lock when ownership of the shared resource is desired. The method includes generating a linked list queue structure containing a first process currently having exclusive access to the lock and one or more processes added to the queue structure to spin on the lock, each process capable of modifying the queue structure by obtaining exclusive access of the lock from a process having exclusive access of the lock and releasing the lock to another process in the linked list queue structure; detecting when one or more processes having exclusive access to the lock terminates, and upon detection, removing the terminated process from the queue structure, and restoring consistency to said linked list queue structure.
摘要翻译：一种用于在具有能够访问共享资源的一个或多个进程的系统中恢复自旋锁的方法，所述系统通过单个进程提供指示对所述共享资源的独占访问的锁定，并使得一个或多个进程能够重复地尝试访问当需要共享资源的所有权时锁定。该方法包括生成链接列表队列结构，该链接列表队列结构包含当前具有对该锁的独占访问权的第一进程和添加到该队列结构以旋转锁的一个或多个进程，每个进程能够通过获得对该队列结构的独占访问来修改队列结构从具有锁的独占访问的进程锁定并将锁释放到链表列表队列结构中的另一进程; 检测何时对所述锁的独占访问的一个或多个进程终止，并且在检测到时，从所述队列结构中移除所述终止的进程，以及恢复所述链表列表队列结构的一致性。

摘要： After receipt of a training and execution plan, a trainer operator is automatically trained based on specified training documents so as to generate a new trained operator for extracting information from documents. The new trained operator is a new version of the trainee operator. Both trainee operators are automatically retained for later use in extracting information from one or more unknown documents. After receipt of the training and execution plan, the new trained operator is automatically executed on one or more unknown documents so as to extract information from such one or more unknown documents.

摘要： Disclosed are methods and apparatus for extracting information from one or more documents. A training and execution plan is received, and such plan specifies invocation of a trainer operator for initiating training of a trainee operator based on a set of training documents so as to generate a new trained operator that is to then be invoked so as to extract information from one or more unknown documents. The trainee operator is configured to extract information from one or more unknown documents, and each training document is associated with classified information. After receipt of the training and execution plan, the trainer operator is automatically executed to train the trainee operator based on the specified training documents so as to generate a new trained operator for extracting information from documents. The new trained operator is a new version of the trainee operator. After receipt of the training and execution plan, both the trainee operator are automatically retained for later use in extracting information from one or more unknown documents and the new trained operator for later use in extracting information from one or more unknown documents. After receipt of the training and execution plan, the new trained operator is automatically executed on one or more unknown documents so as to extract information from such one or more unknown documents.
