Abstract: An improved method to compensate for coupling overhead in a distributed computing system offering a raw processing capacity, comprising an effective processing capacity (404) and the coupling overhead, is disclosed, wherein the distributed computing system comprises at least one computer system and at least one coupling facility. The method comprises determining a coupling efficiency, determining and adding an amount of missing processing capacity to the effective processing capacity based on the coupling efficiency in a way that the effective processing capacity of the raw processing capacity corresponds to a billable target processing capacity.

Abstract: Configuring functional capabilities in a data processing system comprising entitlement data in a non-volatile storage. The position of the data processing system is determined. Based on said position, functional capabilities are changed based on position information comprised in the entitlement data. Changing functional capabilities consists of enabling functional capabilities, disabling functional capabilities, and both enabling and disabling functional capabilities.

Abstract: An integrated hybrid system is provided. The hybrid system includes compute components of different types and architectures that are integrated and managed by a single point of control to provide federation and the presentation of the compute components as a single logical computing platform.

Abstract: A method for configuring functional capabilities in a data processing system. An intermediate link record and a System Anchor record containing the unchangeable hardware ID are used. All entitlement records are then linked to the System Anchor record. Only the System Anchor record links to the unchangeable hardware ID. It contains a system unique ID. The entitlement records link to the System anchor record via the system unique ID. The repair (or upgrade) situation with the exchange of a hardware component now becomes much simpler. There is no exchange of any asset protection record (neither System Anchor record nor entitlement record) required as long as the hardware component comprising the asset protection record is not exchanged. In case the hardware component comprising the asset protection record needs to be exchanged, the System Anchor record only must be exchanged but all the entitlement records can stay unchanged.

Abstract: A method, a computer program product, and a system for generating and applying patches to a computer program concurrently with its execution. It provides full support for function pointers, transparent to the programmer and nearly transparent to the concurrent loader. A reference to a function pointer is translated into a sequence of processor instructions called function descriptor instead of translating it into an address. The purpose of the function descriptor is to jump to the memory location of the sequence of instructions generated by the compiler for the procedure referenced by the function pointer. The function descriptor is masked as a static data variable and therefore preserved during the application of a concurrent patch. The address for the jump to the procedure is updated by the regular relocation process during the application of a concurrent patch.

Abstract: The present invention relates to a method, a computer program product and a system of adding new static data variables and initialisation routines for these variables as part of a method of replacing a current version of a computer program with a replacement version of the program concurrently with the execution of the program on a computer system. This replacement version consists of new machine code completely replacing the existing version, new static data variables and initialisation routines for these variables. The content of the existing static variables will be preserved during the application of the concurrent patch. The concurrent patch can be revoked and the new static data variables can be removed such that the computer program that was executed before the application of the concurrent patch will be executed again.

Abstract: Deploying a software service. A defined software service offering is selected from a plurality of defined software service offerings. An instantiation order for deploying the selected defined software service offering on a corresponding computer system is generated. Each defined software service offering comprises a software service definition and at least one defined software policy. One selected from the group consisting of the software service definition, the software policy, and a combination thereof, provides a hardware configuration for the software service, a software configuration for the software service, and a managing policy for the software service. The instantiation order of the software service for execution on the computer system is created based on the hardware configuration, the software configuration and the managing policy.

Abstract: The invention relates to the configuration of functional capabilities in a computer system. It uses a temporary entitlement record, which contains a set of rules that can be combined in any order. The rules specify entitlements for temporary capacity of the computer system. The configuration is accomplished by assigning the separate activation level structure to each of the currently active offerings. An activation level structure reflects the amount of temporary resources that are active on behalf of a temporary entitlement record, and the amount of resources that the computer system user of this temporary entitlement record will be accounted for.

Abstract: A method and data processing system are disclosed for concurrently loading a plurality of new modules while code of a plurality of modules of an original (i.e., currently running) computer program is loaded and executed on a computer system. The method may comprise allocating a module TLS block for each thread within an initial computer program, wherein the allocated module TLS blocks are large enough to hold all module thread variables that are loaded or to be loaded. The method further may comprise providing constant offsets between module TLS block pointers corresponding to the module TLS blocks and the module thread variables for all of the threads. The disclosed method may be used to add modules to the original computer program and/or to apply a concurrent patch by replacing one or more of the plurality of original computer program modules.

Abstract: According to the present invention a method and a device is provided for concurrent removal of processor capacity from a running computer. The method and device may, e.g., be used for non-disruptive removal of processors from the enabled physical configuration without any involvement of the operating system. The computer comprises a resource controller configured to control a physical resource pool including the actual physical resources and a capacity virtualizer configured to provide multiple sets of virtual resources from a capacity virtualizer resource pool, whereby the provided sets of virtual resources allow to host independent operating systems concurrently.
