  • Apparatus, system, and method for transactional peer recovery in a data sharing clustering computer system
    Patent number: 7870426
    Abstract: The invention provides an apparatus, system, and method for cluster-wide peer recovery in the event of a computer failure. A failure of a first computer is detected and a recovery module is registered as the first computer. In one embodiment, the recovery module is a peer computer. The recovery module retrieves a privately held undo log data through the authorized assumption of the failure identity associated with the failed first computer, backs out in-flight transaction updates of the first computer, and frees up data resources locked by the first computer.

  • SYSTEM AND ARTICLE OF MANUFACTURE FOR PROVIDING AN ADDRESS FORMAT COMPATIBLE WITH DIFFERENT ADDRESSING FORMATS USED FOR ADDRESSING DIFFERENT SIZED ADDRESS SPACES
    Publication number: 20090125689
    Abstract: Provided are a system and article of manufacture for providing an address format compatible with different addressing formats used for addressing different sized address spaces. An address format is used in an operating system to address storage space in a storage device comprising a first region and a second region of storage space. A first group of applications uses the address format to only address the storage space in the first region and is not coded to use the address format to access the second region and a second group of applications uses the address format to address the storage space in the first and second regions.

  • Method and system for recovery from a coupling facility failure without preallocating space
    Patent number: 6910153
    Abstract: A method and system for transparently recovering from a coupling facility failure are disclosed. In one method embodiment, the present invention determines, following the failure of a coupling facility, which data was previously assigned to that coupling facility. The present embodiment then prevents access to that failed coupling facility. Next, the present method embodiment selects a new storage location for the data which was previously assigned to the failed coupling facility. The present embodiment then assigns the data previously assigned to the failed coupling facility to a new storage location. In the present invention, the aforementioned steps are performed without requiring preallocation of white space in an alternate coupling facility.
