Interprocess communication in operating system partition

Abstract

In this method controlling interprocess communication in a single kernel instance operating system partitioned into a global zone and one or more non-global zones, a non-global zone for separating a process from a process in another non-global zone in a global operating system environment controlled by a single kernel instance is established. In compliance with a first request, a communication object having a unique identifier matching the non-global zone of the process making the first request. In compliance with a second request, if it is determined that the process making the second request is associated with the non-global zone having a unique identifier matching that of the communication object, communication is started by using the communication object to the process making the second request.

[0001] Requested priority [0002] This application claims the priority of provisional application No. 60 / 469558 filed by Andrew G. Tucker, et al. on May 9, 2003, titled "OPERATING SYSTEM VIRTUALIZATION", all of which are incorporated herein for reference The content is equivalent to being fully presented here. Background technique [0003] Currently, many computing systems include computing resources that are not fully utilized. By improving the utilization of these computing resources, such underutilization provides potential opportunities for owners of these systems to obtain greater capacity or reduce costs. [0004] Many methods can be used to deal with the problem of increasing utilization, including the merging of multiple applications on a single hardware platform. Consolidation methods typically try to support the coexistence of multiple applications on a single hardware unit in order to obtain greater functionality on fewer hardware platforms. Various computing resource m...
