摘要： A directory and members are allocated to store a data set, wherein the directory stores pointers to the members to allow data stored in the members to be accessed. The directory is expanded to accommodate an expansion of the data set, causing the directory to be stored in non-contiguous pages and becoming fragmented. A computational device determines that a threshold that measures a level of fragmentation of the directory relative to an amount of storage allocated for the data set has been exceeded. The computational device reorganizes the fragmented directory, into a reorganized directory that is stored in contiguous pages at the end of the data set, in response to determining that the threshold has been exceeded.

摘要： Various method and system embodiments for facilitating catalog sharing in multiprocessor systems use multiple ECS cache structures to which catalogs are assigned based on an attribute such as SMS storage class or a high level qualifier (HLQ) (e.g. an N-to-1 mapping) or each individual catalog (e.g. a 1-to-1 mapping). When maintenance is performed on an ECS shared catalog, the multiple ECS cache structure requires only those catalogs associated with a particular ECS cache structure be disconnected. Any catalogs in the structure that are not involved in or affected by the maintenance may be temporarily or permanently moved to a different ECS cache structure. As a result, VVDS sharing is only required for those catalogs on which maintenance is being performed or that remain associated with that ECS cache structure during maintenance. This reduces I/O activity to the DASD, and results in a significant overall performance improvement.
摘要翻译：用于促进多处理器系统中的目录共享的各种方法和系统实施例使用基于诸如SMS存储类别或高级限定符（HLQ）的属性（例如N到1映射）的属性来分配目录的多个ECS高速缓存结构，或者每个单独的目录（例如1对1映射）。当在ECS共享目录上执行维护时，多个ECS缓存结构只需要断开与特定ECS缓存结构相关联的目录。不涉及或受维护影响的结构中的任何目录可以临时或永久地移动到不同的ECS缓存结构。因此，只有在进行维护的目录或维护期间与该ECS缓存结构保持关联的目录中才需要VVDS共享。这样可以降低DASD的I / O活动，从而提高整体性能。

摘要： A data structure maintained in a computational device stores how many control areas splits have occurred to store a data set, wherein each control area split causes an addition of a single new control area. A command is received to add a new data record to the data set. A determination is made as to whether adding the new data record to the data set will result in a threshold for control area splits to be exceeded. In response to determining that adding the new data record to the data set will result in the threshold for control area splits to be exceeded, creating at least two new control areas in addition to continuing to use one existing control area for storing the data set.

摘要： Provided are a method, system, and article of manufacture to manage storage resources in a storage system. Requests by processing systems are received for access to a control block providing information on an address assigned to one of the storage resources to access. A token is generated for each processing system requesting the control block uniquely identifying the processing system and the control block. The processing systems are provided copies of the requested control blocks to use to access the storage resource. A request is received to modify one of the control blocks for one of the storage resources. A determination is made as to whether at least one of the tokens was generated for the control block to modify. At least one processing system associated with the determined at least one token is provided a copy of the modified control block to use to access the storage resource associated with the control block.
