  • Control system for controlling the starting up of a distributed system
    Patent number: 6792526
    Abstract: A control component for controlling the booting up of a complex computer system is described. The control component is configured such that it carries out its task irrespective of changes to the architecture/topology of the computer system. This task is carried out in that the control component controls the booting up of the system on the basis of data that are taken exclusively from a system database.
