  • Synchronizing processing of commands invoked against duplexed coupling facility structures
    Publication number: 20030196025
    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.
    Type: Application
    Filed: October 1, 2001
    Publication date: October 16, 2003
    Applicant: International Business Machines Corporation
    Inventors: Dennis J. Dahlen, David A. Elko, Steven N. Goss, Steven B. Jones, Michael J. Jordan, Georgette L. Kurdt, Jeffrey M. Nick, Kelly B. Pushong, David H. Surman, Douglas Westcott, Wendell W. Wilkinson

  • Method, system and program products for copying coupling facility structures
    Patent number: 6609214
    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.

  • Method, system and program products for copying coupling facility lock structures
    Patent number: 6546414
    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.

  • Method, system and program products for copying coupling facility list structures
    Patent number: 6542970
    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.
