Abstract: A computer operating system manages different types of events. An application program or another part of the operating system defines an event monitor to monitor one or more types of events. The definition also specifies a combination of occurrences of the one or more types of events required to satisfy the event monitor. When each of the monitored events occurs, the event monitor is signalled and stores the event signal. When the event monitor has stored signals which satisfy the event monitor, the event monitor can notify an event handler (pursuant to a standing or subsequent inquiry by the event handler). Then, the event handler can access the stored event signals.

Abstract: Method and apparatus for dynamically providing virtual storage resources to an operating system control program in a computing complex where the control program controls the concurrent execution of multiple virtual machines confer on the control program the capacity to gain access to virtual storage resources through the creation of pseudo-virtual machine control blocks that are available only to the control program.
