摘要： Storage structures of a shared storage processor of a computing environment are copied. A copy operation for a storage structure of the shared storage processor is initiated. Although the storage structure is owned by an exploiter of the storage structure, at least a portion of the contents of the storage structure is copied via an operating system of the computing environment. The at least a portion of the contents are copied from the storage structure to another storage structure of the computing environment. Both storage structures may be located within the same shared storage processor or within different shared storage processors.

摘要： Rebuilding of storage structures within a shared storage processor of a computing environment. A rebuild of a storage structure, which is owned by an exploiter of the storage structure, is initiated. Thereafter, the storage structure is rebuilt via an operating system of the computing environment. The operating system is distinct from the exploiter owning the storage structure and lacks knowledge of the contents of the storage structure.

摘要： A method and apparatus for optimizing a data structure of an external data storage facility shared by a plurality of data processing systems, the data structure being allocated by a first allocation command which includes first allocation parameters based on an amount of storage space in the external data storage facility assigned for creation of the data structure and a composition of the data structure, includes a device for determining values of the first allocation parameters, to thereby determine a first composition of the data structure, a device for determining an actual usage of the data structure, to thereby determine a second composition of the data structure, a device for comparing the first composition of the data structure with the second composition of the data structure, and a device for issuing, based on an output from the comparing device, a second allocation command having second allocation parameters, to the data structure for reallocation thereof. The issuing device includes a device for adjusting the first composition of the data structure to the second composition, as storage space in the external data storage facility and processing cycles become available to execute the second allocation parameters. Until the second allocation parameters are achieved, the reallocation of the data structure remains pending and all processing commands are accepted and processed by the external data storage facility.

摘要： A high-speed cache is shared by a plurality of independently-operating data systems in a multi-system data sharing complex. Each data system has access both to the high-speed cache and the lower-speed, secondary storage for obtaining and storing data. Management logic and the high-speed cache assures that a block of data obtained form the cache for entry into the secondary storage will be consistent with the version of the block of data in the shared cache with non-blocking serialization allowing access to a changed version in the cache while castout is being performed. Castout classes are provided to facilitate efficient movement from the shared cache to DASD.

摘要： A message path mechanism in a network having central processing complexes (CPCs) joined by message paths to a coupling facility. The coupling facility locates message paths for sending messages from one CPC to another and for sending messages between the coupling facility and one or more of the CPCs. A message path status table is provided having an entry for each of the message paths. Each entry has an indicator indicating whether its message path is active or inactive. multiple connections between the coupling facility and systems in the CPCs are registered in the coupling facility. Also provided is a mechanism for validating that each message path is connected properly such that if a message path is disconnected and then reconnected to a CPC, the validation mechanism insures that the message path has been reconnected correctly.

摘要： One or more central processing complexes (CPC's), each with one or more programs being executed, issue commands to a structured electronic storage (SES). The commands include ones that create or delete data structures in SES, and attach or detach users to the data structures. The commands include a comparative authority value operand and a new authority value operand. A data structure or user control information has an associated existing authority value. If the comparative authority value matches the existing authority value, the existing authority value is replaced by the new authority value, and the command is executed. If there is a mismatch, the existing authority value is returned to the program that issued the command, and the command is not executed in SES. This enables software to serialize management of SES and maintain a consistent view of objects in SES in the presence of faulty CPC's, without causing correctly operating CPC's to experience errors or undue delays.
摘要翻译：一个或多个中央处理复合体（CPC），每个具有一个或多个程序被执行，向结构化电子存储（SES）发出命令。这些命令包括在SES中创建或删除数据结构的命令，并将用户附加或分离到数据结构。这些命令包括比较权限值操作数和新的权限值操作数。数据结构或用户控制信息具有相关联的现有权限值。如果比较权限值与现有权限值匹配，则现有权限值将被新的权限值替换，并且执行该命令。如果存在不匹配，则将现有权限值返回给发出命令的程序，并且该命令不会在SES中执行。这使软件能够对SES进行序列化管理，并在出现故障CPC的情况下保持SES中对象的一致视图，而不会导致正确的运行CPC出现错误或不正当的延迟。

摘要： A shared coupling facility contains system lock management (SLM) means for supporting a distributed locking protocol used by a plurality of sharing lock managers each executing on a processor having access to the shared memory and to any other processors in the processor complex. A request to lock a resource shared among the lock managers is first checked against a local hash table and then, if necessary, forwarded to the system lock management means in the shared memory for synchronous or asynchronous processing. List structures are maintained in the shared coupling facility to support the protocol, and are used by the system lock management means to record data recovery status. The sharing lock managers interact with the SLM means to control/manage lock contention, waiter queueing, and compatibility processing.
