Patent ID: 8572044

Claim:
A nested recovery scope management system for use in a computer system having a dynamic multiple address space server environment, the system comprising: a processor, the processor executing: a supervisory program for directing recovery of protected resources, the supervisory program including a first subcomponent for initializing a recovery log, a second subcomponent for storing failure scope tokens and recovery agent references in the recovery log, a third subcomponent for examining the recovery log for a recovery agent reference of the recovery agent references and any current failure scope, and a fourth subcomponent for selectively notifying a recovery agent corresponding to the recovery agent reference to carry out a recovery procedure; the recovery log used by the supervisory program for storing information about recovery agents corresponding to the recovery agent references registered within a recovery scope; at least a first recoverable component for generating a work identifier containing a failure scope token that represents a recoverable operation to be performed at a later time, and for registering the recovery agent with the supervisory program; the recovery agent being a first stateless recovery agent identified in response to initialization of the first recoverable component, the first stateless recovery agent being operable to assist in performing recovery operations in connection with the first recoverable component when instructed to do so by the supervisory program, the first stateless recovery agent also being operable to utilize the work identifier from the recovery log in order to perform recovery operations in connection with the first recoverable component.
