摘要： Disclosed are a method and system of tracking real time use of I/O control blocks on a processing unit basis, in a multiprocessing system, such that in the case of a processing unit failure, a list accurately and concisely identifies the control blocks that need to be recovered. This eliminates the need to scan all the I/O control blocks, greatly reducing the overall system recovery time and minimizing impact to the rest of the running system. The preferred embodiment of the invention uses a task control block structure to record which I/O control blocks are in use by each Processing Unit. Also, the lock word structure defined in the I/O control blocks is provided with an index back into the task control block to facilitate managing the task control block entries.

摘要： Disclosed are a method and system for detecting errors in a computer system including a processing unit to perform tasks to change items. The method comprises the steps of assigning a task control block to the processing unit, and using the task control block to keep track of items being changed by the processing unit. The method comprises the further steps of at defined times, checking the task control block to identify items being changed by the processing unit, and checking the states of said identified items to determine if those states are correct. The preferred embodiment of the invention detects an error when it arises (where possible), and utilizes an infrastructure that allows simple and periodic consistency checks (for example, at designated code points) that detect the error before it causes follow-on problems.

摘要： Disclosed are a method and system for parallel execution of recovery in a non-homogeneous multi-processor environment. The method defines criteria how to decide which recovery actions are to be performed, and on which processor. If multiple recovery actions are pending, the goal is to execute them in parallel on multiple processors. This is much more efficient than the traditional approach of one processor doing all the required recovery. In addition, in large, non-homogeneous systems such a single processor capable of doing the complete recovery might not be existing at all due to technical limitations. The method of this invention also defines rules and mechanisms how multiple processors executing recovery in parallel can access shared resources while avoiding deadlock situations. This includes accessing resources that are currently owned by another processor.
摘要翻译：公开了一种用于在非均匀多处理器环境中并行执行恢复的方法和系统。该方法定义了如何确定要执行哪些恢复操作的标准，以及哪个处理器。如果多个恢复操作未决，则目标是在多个处理器上并行执行它们。这比一个处理器执行所有必要恢复的传统方法更有效率。此外，在大型非均匀系统中，由于技术上的限制，完全恢复的单个处理器可能根本不存在。本发明的方法还定义了并行执行恢复的多个处理器如何可以访问共享资源同时避免死锁情况的规则和机制。这包括访问当前由另一个处理器拥有的资源。

摘要： A bi-directional and full duplex facility for permitting both the IO processor and the Channel to write CCA messages on their respective queues at the same time. IOP messages to the channel are stored on the TO_CHN queue and Channel messages to the IOP on the TO_IOP queue. CCA Queues replace hardware CCAs due to increasing transmission capabilities of current IO processors and Channel processors. Even though the mechanism is similar, the present invention provides some benefits in the use of signaling. The IOP does not have to signal the Channel each time it puts something on its outbound queue. Each queue contains multiple slots. This allows the IOP and Channel to write multiple messages on the targeted queue without encountering a CCA busy signal. The actual queues are now structured in hardware system memory.
摘要翻译：双向和全双工设备，用于允许IO处理器和通道同时在其各自的队列上写入CCA消息。到该通道的IOP消息存储在TO_CHN队列上，并将通道消息存储到TO_IOP队列上的IOP。由于当前IO处理器和通道处理器的传输能力不断增加，CCA队列取代硬件CCA。即使该机制相似，本发明在使用信令方面提供了一些益处。每当它在其出站队列上放置某些东西时，IOP都不必向Channel发出信号。每个队列包含多个插槽。这允许IOP和Channel在目标队列上写入多个消息，而不会遇到CCA忙信号。实际的队列现在由硬件系统内存构成。
