Abstract: A method, system, and computer program product for optimizing query evaluation and processing services in a subscription notification system are provided. The method includes determining hierarchical relationships among a set of subscription queries received from subscription client systems. The hierarchical relationships are determined by identifying subscription queries that are subsets of corresponding other subscription queries in the set. The method also includes creating at least one subscription query at a notification source, the at least one subscription query corresponding to one or more selected subscription queries in the set and including any corresponding subsets.

Abstract: A method and system for managing state data of a service in a service-oriented architecture by establishing a gateway for service-oriented state comprising: configuring an extensible, pluggable interface to support for extensible processor interfaces; data query support on service state data, automated notification capability on service state to a client; and automated data transform on service state data to a client format; defining an interface framework for interaction between a service and the gateway. The method also includes establishing an extensible meta-data definition comprising an extensible set of service state data attributes including state data qualifiers, constraints, and access mechanisms; and utilizing one or more pluggable processors configured to utilize the extensible meta-data definition for interfaces and decision making based on the meta-data.

Abstract: A method for federating the state and behavior of a manageable resource including: retrieving binding information for the manageable resource from a language processor; retrieving a correct proxy instance class name for the manageable resource using the binding information; and creating a proxy instance for a correct provider using the proxy instance class name.
