Abstract: 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.

Abstract translation: 提供了一种在分布式计算环境中对模块负载平衡和故障转移进行编程的方法。 增强了Java管理扩展（JMX）规范，以支持负载平衡并提供JMX管理bean（Mbeans）的高可用性。 还提供了编程模型和基础设施的增强功能，以支持增强的编程模型。 提供了两种用于负载平衡和故障切换的示例性方法，一种基于聚簇的Mbeans，另一种基于未聚簇的Mbeans。 在非集群方法中，支持客户端关联，因为来自特定客户端的请求可以路由到特定的Mbean。 在集群方法中，可以通过在Mbean调用中提供一个特殊参数或通过向特定的Mbean的ObjectName添加一个特殊属性来指示在运行时自动路由不应该使用的特定Mbean。

Abstract: 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.
