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.
