    摘要： A system and method for using a declarative approach to enforce instance based security in a distributed environment is presented. The invention described herein includes security logic in declarative specifications that, in turn, decouples the security logic from distributed object administration logic. An access manager identifies access requirements by combining object name property keys included in a distributed object with property key specifications included in a declarative specification. In turn, the access manager compares a caller's access attributes with the access requirements to determine whether to create a distributed object instance and allow the caller to invoke a method on the distributed object instance. The access requirements may also include role specifications and method parameter specifications.

    摘要： Provided is a method for programming module load balancing and failover in a distributed computing environment. The Java Management extensions (JMX) specification is enhanced to support load balancing and provide a high-availability of JMX management beans (Mbeans). Also provided are enhancements to the programming model and infrastructure to support the enhanced programming model. Two exemplary approaches for load balancing and failover are provided, one based both upon clustered Mbeans and one based upon unclustered Mbeans. In the unclustered approach, client affinity is supported in that a request from a particular client can be routed to a particular Mbean. In the clustered approach, a specific Mbean can be invoked by providing a special parameter in the Mbean invocation or by adding a special property to the specific Mbean's ObjectName to indicate that during runtime automatic routing should not be employed.

    摘要： A meta-data driven method and apparatus to manage configurations of coexisting heterogeneous subsystems. The present invention recognizes that schemas evolve incrementally from version to version. In a preferred embodiment, the present invention employs two stages: an identification specification stage, to identify and/or specify any changes in a heterogeneous distributed system, and a configuration validation stage, to implement and/or validate the changes thus identified or specified. In the first stage, the identification specification stage, the present invention programmably compares the next version of the schema from its previous version. This allows meta-data to be created that describes how a schema component evolves from version to version. In addition, a user may specify what appears in the schema. In the second stage, the configuration validation stage, the meta-data created in the first stage can be used to determine whether a particular component version of the subsystem is valid for a particular schema component, and vice versa, and/or to configure the subsystem to conform to the schema.
