Abstract: 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.

Abstract: Several methods and a system of a workload management of a concurrently accessed database server are disclosed. In one embodiment, a method includes applying a weight to a service class. The method also includes generating a priority of the service class. In addition, the method includes selecting a group based on the weight of the service class. The method further includes determining a priority level based on the priority of the service class. The method also includes generating a characteristic of a shadow process through the weight and the priority of the service class. In addition, the method includes executing a query.

Abstract: 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.
