摘要： Changes in locking configurations are managed. A locking configuration includes one or more locking facilities and the one or more locking facilities include one or more locks. When a change in a locking configuration, either planned or unplanned, is detected, one or more of the locks are redistributed. For example, one or more of the locks affected by the change are moved from one or more of the locking facilities to one or more other locking facilities. This redistribution is independent of the location of the data associated with the one or more locks being moved. Thus, data and locks may be moved independently of one another and without affecting one another. Further, the redistribution can take place while the system is available or mostly available, thereby minimizing downtime.
摘要翻译：锁定配置的更改被管理。锁定配置包括一个或多个锁定设施，并且一个或多个锁定设施包括一个或多个锁。当检测到计划中或未计划的锁定配置发生变化时，将重新分配一个或多个锁。例如，受变化影响的一个或多个锁从一个或多个锁定设施移动到一个或多个其他锁定设施。该重新分配与所移动的一个或多个锁相关联的数据的位置无关。因此，数据和锁可以彼此独立地移动而不彼此影响。此外，重新分配可以在系统可用或大部分可用的情况下进行，从而最小化停机时间。

摘要： A method and apparatus of assigning and releasing locks, in a network computing environment having a plurality of central processing units coupled to a high performance locking facility. The method comprises of the steps of first receiving and processing a lock operation synchronous to any requesting central processor unit requesting a lock and then recording lock names and lock states in entry records of a lock table based on the requests. When a request is being processed, providing high-speed searching to search any particular lock entry in the table and altering and modifying the table accordingly. Finally an appropriate response and the status of the lock state will be generated and sent to other requesters requesting the lock.

摘要： The present invention provides for a computer program product and device including instructions executable by a digital processing apparatus for conducting a high-performance locking facility. At first multiple requests for locking operations are processed and received simultaneously and their lock names and lock states are recorded in entry records of a lock table based on the requests. Next high-speed searching of any particular lock entry in this table is performed followed. The table can be altered and modified at this time as well accordingly depending upon lock status that is being processed. Finally an appropriate response is generated and the status of the lock state is provided to those requesting the lock.

摘要： A method and apparatus for serializing access by n entities to a shared resource in an information handling system. A waiter list is defined as a circular list of n bits, each of which is assigned to an entity. When a bit is false (0) it indicates that the corresponding entity is not waiting for the lock; when the bit is true (1) it indicates the corresponding entity is waiting for the lock. A next waiter indicator (NWI) is also defined that contains a value from 0 to n inclusive; a value of 0 indicates that there are currently no waiters, while a value from 1 to n indicates the next waiter to whom the lock will be granted. The waiter list is initialized to zeros to indicate there are no waiters. When an entity requests a lock that cannot be granted, the entity is made a waiter by setting the corresponding bit in the waiter list to one. If the next waiter indicator is zero, indicating that there were previously no waiters for the lock, the indicator is set to identify the requesting entity as the next waiter. When a lock is released and there is a next waiter for the lock as indicated by the next waiter indicator, that waiter is made a lock holder and the corresponding bit in the waiter list is reset to indicate that the entity is no longer a waiter for the lock. A new next waiter is then found by scanning the waiter list beginning with the entry following that for the entity granted access to the resource. This ensures that once a waiter releases a lock, the waiter is not selected to receive the lock again until all other waiters have received the lock.
摘要翻译：一种用于将n个实体的访问序列化到信息处理系统中的共享资源的方法和装置。服务员列表被定义为n位的循环列表，其中每个被分配给一个实体。当一个位为false（0）时，表示相应的实体不在等待锁定; 当该位为真时（1）表示相应的实体正在等待锁定。还定义了下一个服务员指示符（NWI），其中包含0到n的值; 值0表示当前没有服务员，而从1到n的值表示将被授予锁的下一个服务员。服务员列表初始化为零，表示没有服务员。当实体请求不能授予的锁时，通过将服务员列表中的相应位设置为1来将实体设为服务员。如果下一个服务员指示符为零，表示以前没有服务员进行锁定，则指示符将被设置为将请求实体标识为下一个服务员。当锁定被释放并且下一个服务员如下一个服务员指示符所指示的那个服务员时，该服务员被制成一个锁持有者，并且服务员列表中的相应位被重置以指示该实体不再是服务员锁。然后通过扫描服务员列表开始的条目，然后通过授予访问资源的实体，找到新的下一个服务员。这样可以确保一旦服务员释放锁定，则在所有其他服务器都已收到锁定之前，服务员不会再次接收锁定。
