Method and apparatus for reservation and reallocation of surplus resources to processes in an execution space by a local resource manager after the execution space is generated succeeding the initialization of an application for which the execution space is created and the resources are allocated to the execution space by a global resource manager prior to application execution

Abstract

A certain process included in a first execution space requests a local resource manager to allocate a resource. The local resource manager obtains the authentication ID of the process issuing the request and determines whether or not the resource can be allocated. If the resource can be allocated and the resource previously secured in the execution space can suffice the request, the local resource manager allocates the resource to the process. If the resource is insufficient, the local resource manager requests a global resource manager to allocate the resource. The global resource manager obtains the authentication ID of the first execution space issuing the request and determines whether or not the resource can be allocated. If it is determined that the resource can be allocated, the resource is allocated to the first execution space.
