    摘要： A method, apparatus, and system are directed toward managing a system that includes a cluster and an external resource. The external resource may be part of a second cluster that is collocated on the same hardware platforms as the cluster. A proxy resource is used to enforce a dependency relationship between a native resource of the cluster and an external resource, such that a dependency with the proxy resource serves to enforce a dependency with the external resource. The cluster framework may maintain states of the proxy resource, including an offline state, an online-standby state, and an online state. The online-standby indicates that the proxy has been started, but it has not determined that the associated external resource is enabled. The proxy may determine whether the external resource is enabled or disabled and, in response, notify the cluster framework.

    摘要： A method, apparatus, and system are directed toward configuring a dependency relationship between resources in a cluster. A dependency relationship between a dependent in a first resource group and a dependee in a second resource group is declared. The dependency relationship might include a locality based qualifier and/or a time based qualifier. The locality based qualifier includes a Local Node, Any Node, or From Resource Group Affinity relationship. The time based dependency qualifier includes a Strong dependency, Weak dependency, Online Restart dependency, or Offline Restart dependency. The declaration might be made using a graphical user interface, property list, configuration file, or the like. A candidate node on which to activate the first resource group is determined. The dependent is brought online on the candidate node based on whether an instance of the dependee is online on a node specified by the locality based qualifier.

    摘要： The present invention describes a method and system for managing high-availability-aware components in a networked computer system. In particular, the method includes registering components and dynamically allocating roles and assignments to one or more of the registered components to achieve a desired level of redundancy based on component type information. The method may include an additional step of performing administrative actions on the registered components in response to a request from an external management agent in order to increase the availability of services provided by the high-availability-aware components. Further, the method may additionally include responding to an error by changing roles and assignments of one or more of the registered components, providing information to registered components so that related components may communicate to achieve a desired redundancy level, and/or maintaining additional information relevant to managing high-availability-aware components. Such additional information may include information regarding software release domains, component relationships, and/or protection groups.
