Appl. No.:

9/144424

David Maxwell Cannon - Tucson AZ

International Classification:

G06F 1500

US Classification:

712 28

Abstract:

In a multiprocessing system, hierarchically superior configuration managers maintain profiles of operating characteristics to which subordinate managed units selectively subscribe. If the profiles or operating characteristics change, the configuration managers propagate the changes to all managed units. Each configuration manager stores a record of operating characteristics and multiple server profiles, each profile specifying one or more operating characteristics. A subscription list identifies one or more managed units, each associated with one or more server profiles. Each managed unit acts according to its current operating characteristics, stored locally at the managed unit. If the managed unit receives a profile subscription request from a system administrator, the managed unit sends a subscription message to the configuration manager to subscribe to that input profile. Receiving the subscription, the configuration manager enters the subscribing managed unit and the associated profile into the subscription list, and returns the profiled operating characteristics to the subscribing managed unit. The subscribing managed unit stores these operating characteristics in its record of current operating characteristics.

Abstract:

In a multiprocessing system, a configuration manager maintains various reference parameters that are selectively copied by subordinate managed units to form local operating parameters, which subsequently govern operation of these managed units. A comparative technique is employed to track reference parameter updates, and synchronize each local operating parameter counterpart accordingly. At the configuration manager, reference parameters include reference profiles and reference characteristics. Each reference profile specifies one or more of the reference characteristics. At each managed unit, the operating parameters include subcribed-to profiles and operating characteristics; both are initially copied from the configuration manager's reference profiles/characteristics. Each local operating profile specifies one or more of the operating characteristics. Each managed unit operates according to its locally maintained operating characteristics.
