Abstract: A decision support system called Mounties that is designed for managing applications and resources using rule-based constraints in scalable mission-critical clustering environments. Mounties consists of four active service components: (1) a repository of resource proxy objects for modeling and manipulating the cluster configuration; (2) an event notification mechanism for monitoring and controlling interdependent and distributed resources; (3) a rule evaluation and decision processing mechanism; and (4) a global optimization service for providing decision making capabilities. The focus of this paper is on the design of the first three services that together connect and coordinate the distributed resources with the decision making component.

Abstract: A method and system for model-driven transformation are provided. The method and system in one aspect allows selecting of one or more model elements in a model. Transformation definitions are evaluated to identify one or more transformations that may be applicable to the selected one or more model elements. In one aspect, transformations may be identified that are applicable in an entire model, those that take the selected one or more model elements as input parameters, those that affect one or more model element, or any combination thereof. In one aspect, a list of applicable transformations is presented. In another aspect, the method and system automatically apply the one or more applicable transformations to the model.

Abstract: A system and method for automated design deployment for distributed applications includes providing a node with at least one requirement attribute in an application description. A repository for infrastructure elements is searched for candidate infrastructure elements for that satisfy the at least one requirement attribute. A candidate infrastructure element that best satisfies the at least one requirement attribute in the application description is substituted in place of the node with the at least one requirement attribute.

Abstract: A computer implemented method and a computer program product provide a provisioning system for automated provisioning of a computing infrastructure by providing relationship factories with resources of the computing infrastructure. The relationship factories include information necessary for establishing relationships within the computing infrastructure. The provisioning system ranks relationship factories according to suitability to provide for appropriate provisioning of new resources added to the computing infrastructure.

Abstract: The present invention is directed to provisioning and managing computing services in a computing utility system. It receives as an input an infrastructure independent description of a set of requirements on the new desired state of a computing service. It uses a knowledge plane to represent the infrastructure. The method generates a Concrete Model that describes a resource structure that refines the input and is implementable over the infrastructure. It then generates and possibly executes provisioning actions to create an identical resource structure on the infrastructure. The method can be used to create new computing services, to destroy existing computing services, to modify the resource combinations allocated to a computing service, or the configuration of these resources. Provisioning actions can be executed immediately, or saved and executed later, and possibly many times.

Abstract: A method for developing a computer program product includes: evaluating one or more refactoring actions to determine a performance attribute; associating the performance attribute with a refactoring action used in computer code; and undoing the refactoring action of the computer code based on the performance attribute.

Abstract: An embodiment of the invention provides a method of managing a cluster of networked resources and resource groups using rule-based constraints. This method includes the step of building a globally optimal cluster configuration of the resources in accordance with the rule-based constraints and a current state of the resources, including identifying for each of the resources and resource groups an availability and quality of service, which are determined by dependencies among the resources and resource groups, resource equivalency, constraints on the resources and network policies. The method comprises the further steps of bringing the cluster of resources on-line in a systematic manner, given the current state of each of the resources and resource groups; and with the cluster of networked resources on-line, determining dynamic dependencies of and configuration infomration about the cluster of resources (i) statically at defined times and (ii) dynamically during cluster operation.

Abstract: A method and apparatus for providing non-privileged state cross-memory communications between application programs in disjoint communication memory domains. Appropriate operating systems store a table indicating which communication memory domains and which operations are permitted by a corresponding application program in a corresponding communication memory domain.

Abstract: A method and apparatus for coupled computer systems provides a single network node image when connected to a computer network, so that the network is unaware of the "fine" structure of the computer systems in the machine room. The coupled complex is made available to the network.
