  • Main storage and expanded storage reassignment facility
    Patent number: 6026462
    Abstract: A data processing system has a processing unit and a memory which provides a common pool of physical storage. This storage is initially assigned as either main storage or expanded storage during power on. Subsequent to the initial assignment, storage assigned as main storage or expanded storage may be unassigned and thus returned to the common pool. Once returned to the common pool, the storage may be reassigned as either main storage or expanded storage. The storage reassignment is done dynamically without requiring a reset action and transparent to the operating system and any active application programs.
    Type: Grant

  • Method and apparatus for dynamic storage reconfiguration in a partitioned environment
    Patent number: 5819061
    Abstract: In a partitioned process environment, storage is reassigned by a shuffle of guest absolute address spaces which may be reassigned among partitions without restriction as to the position of the space to be reassigned relative to the position of the partition to which it is to be assigned. The reassignment is accomplished by adjusting the origin addresses by an adjustment value corresponding to the size of the address space of an additional memory area to be added to a selected partition. Furthermore, the size of the address space of the selected partition is increased by the same adjustment value. The system employs duplicated origin and limit arrays which are used to convert from a partition (guest) absolute address to a system (host) absolute address and uses duplicated configuration arrays by which the system absolute addresses are converted to physical memory addresses.

  • Dynamic Reconfiguration of main storage and expanded storage by means of a service call logical processor
    Patent number: 5704055
    Abstract: A data processing system has a processing unit and a memory which provides a common pool of physical storage. This storage is initially assigned as either main storage or expanded storage during power on. Subsequent to the initial assignment, storage assigned as main storage or expanded storage may be unassigned and thus returned to the common pool. Once returned to the common pool, the storage may be reassigned as either main storage or expanded storage. The storage reassignment is done dynamically without requiring a reset action and transparent to the operating system and any active application programs.
