Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

G06F 1200

US Classification:

711145, 711113

Abstract:

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.

US Classification:

709201, 714 5, 714 11

Abstract:

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.

International Classification:

G06F 1100

US Classification:

714 5, 714 15

Abstract:

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.

International Classification:

G06F013/14

US Classification:

710306, 710305, 710312, 710313

Abstract:

A coupling facility is coupled to one or more other coupling facilities via one or more peer links. The coupling of the facilities enables various functions to be supported, including the duplexing of structures of the coupling facilities. Duplexing is performed on a structure basis, and thus, a coupling facility may include duplexed structures, as well as non-duplexed or simplexed structures.

International Classification:

G06F 11/16

US Classification:

714 15, 714 4, 714 5, 714 6, 714 42, 709213, 709217, 370276

Abstract:

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).

International Classification:

G06F 11/00

US Classification:

714 4

Abstract:

A system and method for detection of and a policy directed resolution of signaling sympathy sickness. Embodiments include a system having a communication among the members, each member having a cross-system coupling facility (XCF), and a method of managing sympathy sickness, the method including detecting a sympathy sickness condition affecting at least one of the members, documenting the sympathy sickness condition and implementing a policy rule to resolve the sympathy sickness condition.

International Classification:

G06F 9/00

US Classification:

713 2

Abstract:

A method for automatically updating persistent boot parameter storage in a computer system includes storing updated boot parameters for an operating system in the computer system in a hardware boot parameter storage area in a memory of the computer system; performing a reboot of the operating system with the updated boot parameters; determining whether the reboot of the operating system is successful; and, in the event the reboot of the operating system is successful, automatically propagating the updated boot parameters from the hardware boot parameter storage area to a persistent boot parameter storage area.
