A system or computer usable program product for managing jobs scheduled for execution on a target system in which some jobs may spawn additional jobs scheduled for execution on the target system including intercepting jobs scheduled for execution in the target system, determining whether there is resource sufficiency in the target system for executing jobs, responsive to an affirmative determination of resource sufficiency, releasing previously intercepted jobs for execution in the target system, computing a limit of a number of jobs which can be concurrently scheduled by an external system to the target system, and transmitting the computed limit to the external system.
