摘要： An apparatus for and method of enhancing reliability within a cluster lock processing system having a relatively large number of commodity cluster instruction processors which are managed by a cluster lock manager. Because the commodity processors have virtually no system viability features such as memory protection, failure recovery, etc., the cluster/lock processors assume the responsibility for providing these functions. The low cost of the commodity cluster instruction processors makes the system almost linearly scalable. The cluster/locking, caching, and mass storage accessing functions are fully integrated into a single hardware platform which performs the role of the master. Upon failure of this hardware platform, a second redundant hardware platform converts from slave to master role. The logic for the failure detection and role swapping is placed within software, which can run as an application under a commonly available operating system. Furthermore, the recovery is completely accomplished without assistance of the Host computer(s) or ultimate user(s) coupled via the Host computer(s).

摘要： An apparatus for and method of providing failure recovery from redundancy, notwithstanding that the failed subsystem and its replacement have differing capacities. This is especially useful when implementing a cluster lock processing system having a relatively large number of commodity instruction processors which are managed by a highly scalable, cluster lock manager. Reliability is built into the managing communication processor by dividing the system into master and slave subsystems. The master has primary responsibility for system management and coordination, whereas the slave has primary responsibility to backup the master and be prepared to assume management responsibility. Upon the need to transfer responsibility from the master to the slave, whether it be manual (e.g., maintenance) or automatic (e.g., failure), the only concern is that the slave has sufficient capacity to accept the current level of processing, even though it does not have the same level of capacity as the master.

摘要： An apparatus for and method of enhancing reliability and performance within a cluster lock processing system having a relatively large number of commodity instruction processors which are managed by a highly scalable, off the shelf platform. Because the commodity processors have virtually no system viability features such as memory protection, failure recovery, etc., the cluster/lock processors assume the responsibility for providing these functions. The low cost of the commodity instruction processors makes the system almost linearly scalable. The cluster/locking, caching, and mass storage accessing functions are fully integrated into a single hardware platform which performs the role of the cluster/lock master. The validity operation throughput of the clustered systems manager is increased by aging out validity entries for each of the process owners via a background operation. This minimizes the number of exclusive locks that must be utilized while performing a validity operation.

摘要： An apparatus for and method of implementing a cluster lock processing system using highly scalable, off-the-shelf commodity processors. The cluster lock processing system is the central component of a clustered computer system, providing locking and coordination between multiple host systems. The host systems are coupled to the cluster lock processing system using off-the-shelf, low latency interconnects. The cluster lock processing system is composed of multiple commodity platforms that are also coupled to each other using low latency interconnects. Failure of one of the commodity platforms that comprise the cluster lock processing system results in no loss of functionality or interruption of service. This is made possible through the use of specialized software that runs on the commodity platforms. Through the use of custom software and inexpensive hardware the overall system cost is dramatically reduced when compared to typical solutions that use custom built hardware. By allowing the individual commodity platforms to be physically separated, the cluster lock processing system also provides for resiliency against physical damage to an individual platform that may be caused by a catastrophic site failure.
摘要翻译：一种使用高度可扩展的现成的商品处理器来实现集群锁处理系统的装置和方法。集群锁处理系统是集群计算机系统的核心组件，提供多个主机系统之间的锁定和协调。主机系统使用现成的低延迟互连耦合到集群锁处理系统。集群锁处理系统由多个商品平台组成，它们也使用低延迟互连彼此耦合。构成集群锁处理系统的商品平台之一的故障不会导致功能损失或服务中断。这可以通过使用在商品平台上运行的专门软件来实现。通过使用定制软件和廉价硬件，与使用定制硬件的典型解决方案相比，整体系统成本大大降低。通过允许各个商品平台在物理上分开，集群锁处理系统还提供弹性，以防止可能由灾难性的站点故障引起的个体平台的物理损坏。

Furthermore, the recovery is completely accomplished without assistance of the Host computer(s) or ultimate user(s) coupled via the Host computer(s). Following repair of the failed server, it is restarted in an orderly fashion to resume a slave role. For the server to be completely restored, coherent memory must be copied from master to slave. Because cluster lock processing must be paused throughout the system to transfer the copy, it is important to minimize the transfer time to minimize the impact on system throughput.

摘要： A data processing system including a first and second host, a first and second outboard file cache connected to the first host, and a first and second secondary storage device connected to the first host. The system operation includes the first host reading file data from the first or second secondary storage device after the data is cached on both the first and second outboard file caches. File data is updated by writing to both first and second outboard file caches. File data is destaged by writing data from the first outboard file cache only, to first and second secondary storage devices. Failure of a single outboard file cache is handled by the first host not reading and writing to the failed outboard file cache. Site-wide failure of first host, first outboard file cache, and first secondary storage device is handled by establishing communication from second host to both second outboard file cache and second secondary storage device and resuming processing.

摘要： A disk cache translation system for mapping data record lengths between systems having different data record lengths. Command queue (315) maps into initiation queue (305) to allow I/O manager (230) to manage I/O requests from operating system (125). I/O requests are statused by I/O manager (230) using status queue (325). Store-thru cache (280) provides a single interface to disk array (270) such that disk array write operations are reported complete only when user memory (250), I/O cache (280) and disk array (270) are synchronized. Data record length translations are performed using I/O cache (280) in order to align data record length differences between operating system (125) and I/O device (270).

摘要： A transaction processing audit and recovery system is disclosed. After processing a transaction, an audit manager logs in audit records only changed blocks of data of a segment of a database. Upon failure of database backing storage, a prior copy of the database is reloaded to database backing storage that is available and a recovery manager reads the audit records and copies the changed blocks back to the database backing storage. An outboard file cache system is used in conjunction with the recovery manager to recover the database. The outboard file cache provides cache storage for segments of the database and writes non-contiguous blocks of one or more segments as directed in a single input/output request initiated from the recovery manager.
