Abstract: A method of controlling resource consumption of running processes, sub processes and/or treads (such as a database or an application transaction) in a computerized system, in which resources consumed by less important processes are freed by periodically suspending (by causing them to demand less resources) and resuming these processes transparently to other entities of the computerized system and externally to the OS without intervention in its inherent resource allocation mechanism and allowing the OS of the computerized system to allocate the free resources to other running processes.
