The invention suggests providing in a processing system a licence controller ( 1 ), for controlling use of a resource by processes ( 3, 5, 7 ); for each process to be controlled, there is provided an inter-process communication ( 9, 11 ) between the process and the licence controller. A process and the licence controller exchange through the inter-process communication of the process information regarding actual and allowed use of the resource by the process. According to this information, the process may be controlled, be it on a self-control basis or through control of the licence controller. Use of the resource to be dynamically adapted; high availability is guaranteed since processes may operate even when the licence controller fails.
