摘要： An apparatus and method of efficiently recovering from physical disk drive (or logical file) failures in transaction based digital data processing systems. As transactions are sequentially processed, compacted audit trail records are prepared to indicate modifications resulting from each transaction. The audit trail records are stored in storage areas on a disk drive in accordance with the physical data base disk drive(s) or logical file(s) to which the corresponding transaction refers. A physical disk drive or logical file is dumped to magnetic tape whenever the associated audit trail storage area is full, thus clearing the audit trail storage area for further use. When a physical disk drive or logical file fails, the most recent dump is read. Modifications to each file of the dump are made as compacted audit trail data is processed. The modified files are destaged to a spare disk drive.

摘要： Method and apparatus for providing backup memory storage for audit trail data within a computer system having a main memory storage, a non-volatile memory storage, and backup memory storage. The computer system executes a number of transaction programs which generate audit trail entries. As the audit trail entries are generated, a portion of the audit trail entries are stored in a portion of the main memory storage to create an audit trail. The audit trail entries are accumulated in the portion of the main memory storage until a request is received to write the portion of the main memory storage to a corresponding portion of the non-volatile memory. Subsequent portions of the audit trail entries are accumulated in subsequent portions of the main memory storage. An output transfer to the backup memory storage is made once a sufficient number of portions of the main memory storage have been written to corresponding portions of the non-volatile memory in order to maximize the transfer efficiency to the backup memory storage.
摘要翻译：用于在具有主存储器存储器，非易失性存储器存储器和备用存储器存储器的计算机系统内提供用于审计跟踪数据的备份存储器存储器的方法和装置。计算机系统执行多个生成审计跟踪条目的事务程序。当生成审计跟踪条目时，一部分审计跟踪条目存储在主存储器存储器的一部分中以创建审计跟踪。审计跟踪条目累积在主存储器存储器的部分中，直到接收到请求以将主存储器存储器的部分写入到非易失性存储器的对应部分。审计跟踪条目的后续部分被累积在主存储器存储器的后续部分中。一旦将主存储器存储器的足够数量的部分写入到非易失性存储器的对应部分中，就可以进行到备份存储器存储器的输出传输，以便最大化对备份存储器存储器的传送效率。

摘要： Method and apparatus for managing the allocation and release of memory space within a number of files shared by a number of hosts in a data processing system. A number of allocate and release tables are provided which are accessible by the number of hosts for managing the allocation and release of space within the number of files. Each one of the number of allocate and release tables corresponds to one of the number of files and provides a file location, file size, and indication to the number of hosts of which of the number of blocks within the file have been allocated and which of the number of blocks have been released. Any host may allocate one or more of the number of blocks to store messages created or received by the host by determining from the allocate and release tables which one or more of the number of blocks within one of the number of files are available. The host may then release the one or more of the number of blocks once the one or more of the number of blocks are no longer required to store the message. Once the one or more of the number of blocks are released, any of the number of hosts may allocate and release additional messages.

摘要： A system and method for maintaining a backup data base. An initial backup copy of a data base is made and stored separate from an active primary data base. Each time the primary data base is updated, audit information pertaining to the data base update is stored in non-volatile storage. A recovery processor continuously reads the audit information from the non-volatile storage and updates the backup data base accordingly, thereby maintaining a backup data base which is nearly up-to-date with the primary data base.

摘要： Method and apparatus for tracking messages and transactions communicated between a number of users and a number of hosts, where the hosts are executing concurrent applications. During a first user session, a first user communicates with a first host. A counter associated with the first user session is incremented when the application creates an output message. The counter is decremented when the output message is released to the first user. A flag associated with the first user session is set and the counter is incremented once the flag is set, if an input message or committing transaction is received from the first user. The flag is cleared and the counter is decremented when the input message or committing transaction is processed by the concurrent application. The counter being decremented indicates there are no dependencies during the first user session with regard to the output message, input message, or committing transaction. If a second user session is initiated with a second host, the second host determines if there are any dependencies with the first user session. A dependency exists if the output message is created but not released, or if the input message or committing transaction is received but not processed. If there are dependencies, the first user session is reestablished to resolve the dependencies, otherwise, the second session is continued.
摘要翻译：用于跟踪在多个用户和主机执行并发应用程序的主机之间传递的消息和事务的方法和装置。在第一用户会话期间，第一用户与第一主机通信。当应用程序创建输出消息时，与第一用户会话关联的计数器递增。当输出消息被释放到第一个用户时，计数器递减。如果从第一用户接收到输入消息或提交事务，则设置与第一用户会话关联的标志，并且一旦设置了标志，则计数器递增。当并发应用程序处理输入消息或提交事务时，标志被清除，计数器递减。计数器递减表示在第一个用户会话期间关于输出消息，输入消息或提交事务没有依赖关系。如果用第二主机发起第二用户会话，则第二主机确定是否存在与第一用户会话有任何依赖关系。如果输出消息被创建但未被释放，或者输入消息或提交事务被接收但未被处理，则存在依赖关系。如果有依赖关系，则重新建立第一个用户会话来解析依赖关系，否则第二个会话继续。

摘要： A multiprocessor data processing system is implemented with processors, each of which may request for a temporary time the exclusive lock on an object which is stored on a data base. To achieve this a lock processor synchronizes the locking and unlocking of the objects. The requesting processor directs the storage of the object from the data base into a selected high performance storage unit, where it has exclusive rights to modify or write into the object until the object is unlocked by the processor. An audit tape or disk records all modifications made to any object during a transaction. A non-volatile cache memory is inserted in the audit trail to store a before-look image of the object that resides in the high performance storage unit. Data compaction occurs by comparison of the before-look image with an after-look image to provide a difference image, which is supplied to an audit buffer that is coupled to the audit tape. The locking processor may unlock the secured object once the after-look image has been committed from either a stored version in the non-volatile cache or from a high performance main memory unit to the data base disk. The difference image and the after-look image associated with the difference image may then be stored in the non-volatile cache, and provided to the audit tape or disk and the data base disk in a sequence which is independent of the operating sequence of the requesting processor.
摘要翻译：处理器实现多处理器数据处理系统，每个处理器可以请求临时时间对存储在数据库上的对象的排他锁定。为了实现这一点，锁定处理器同步对象的锁定和解锁。请求处理器将对象从数据库的存储引导到所选择的高性能存储单元中，其中它具有修改或写入对象的专有权利，直到对象被处理器解锁。审核磁带或磁盘记录在事务期间对任何对象所做的所有修改。非易失性高速缓冲存储器插入到审计跟踪中，以存储位于高性能存储单元中的对象的前景图像。数据压缩通过将前景图像与后视图像进行比较而发生，以提供差分图像，该图像被提供给耦合到审核磁带的审核缓冲器。一旦后视图像已经从非易失性高速缓存中的存储版本或从高性能主存储器单元提交到数据库磁盘，锁定处理器可以解除安全对象。与差分图像相关联的差异图像和后视图像然后可以存储在非易失性高速缓存中，并以独立于操作顺序的顺序提供给审核磁带或磁盘和数据库磁盘请求处理器。
