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.

List structures of a shared storage processor of a computing environment are copied. A copy operation for a list structure of the shared storage processor is initiated. Although the list structure is owned by an exploiter of the list structure, one or more objects of the list structure are copied via an operating system of the computing environment. The one or more objects are copied from the list structure to another list structure of the computing environment. Both list structures may be located within the same shared storage processor or within different shared storage processors.
摘要:
Lock structures of a shared storage processor of a computing environment are copied. A copy operation for a lock structure of the shared storage processor is initiated. Although the lock structure is owned by an exploiter of the lock structure, one or more objects of the lock structure are copied via an operating system of the computing environment. The one or more objects are copied from the lock structure to another lock structure of the computing environment. Both lock structures may be located within the same shared storage processor or within different shared storage processors.
摘要:
Cache structures of a shared storage processor of a computing environment are copied. A copy operation for a cache structure of the shared storage processor is initiated. Although the cache structure is owned by an exploiter of the cache structure, one or more objects of the cache structure are copied via an operating system of the computing environment. The one or more objects are copied from the cache structure to another cache structure of the computing environment. Both cache structures may be located within the same shared storage processor or within different shared storage processors.
摘要:
System-managed duplexing of coupling facility structures. A plurality of instances of coupling facility structures are maintained in a plurality of coupling facilities. Duplexing processing associated with the plurality of instances is managed by one or more operating systems, making many of the steps associated with duplexing transparent to the exploiters of the coupling facility structures. System-managed duplexing provides high availability for coupling facility structure data via a robust recovery mechanism (i.e., duplexing failover).
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:
Fully-associative non-linear collections of items are browsed. At least a portion of a fully-associative non-linear collection of items is segmented into a plurality of segments. This segmenting is transparent to any browsers of the fully-associative non-linear collection of items. The plurality of segments is then browsed by multiple browsers.
摘要:
Storage structures of a shared storage processor of a computing environment are modified. One or more target maximum counts are specified, which are to be used in modifying a storage structure of the shared storage processor. The one or more target maximum counts are then used to modify the storage structure.
摘要:
Storage structures are allocated within a shared storage processor of a computing environment. One or more target maximum counts are specified, which are to be used in allocating a storage structure of the shared storage processor. The one or more target maximum counts are then used to allocate the storage structure. The newly allocated structure can have the same characteristics as a previously allocated structure.
