Controlling Access to Services and/or Resources of a Data Processing System

Kurzfassung/Abstract

In order to control access to resources of a data processing System, a priority code is determined for an access request to at least one resource. A comparison code for granting access to the at least one requested resource is determined concerning an alternative use of the resource. For a totality of resource requests to the data processing System, an extreme value for a sum is determined via products of a corresponding priority code and of a number of resource accesses which can be granted in each case, taking into account a maximum capability of a requested resource. For a resource request, it is checked whether the priority code and the comparison code show a predetermined mutual relation. Access is granted depending on the extreme value determined and on the result of the check.
