ABSTRACT:
A system and associated method for determining a recovery time for a resource in a heterogeneous computing environment comprising interdependent resources. A graph for the resource representing all sequence dependencies and all group relations are created. The recovery time may be a cumulative startup time or a cumulative shutdown time of the resource considering interdependencies of the resource to other resources. The recovery time for all support resources having sequence dependencies with the resource is calculated and each node representing the support resources are removed from the graph. Then the recovery time for all member resources left in the graph that have group relations with the resource is calculated per a group type of the resource. The recovery time for the resource is a sum of the recovery time of all support resources, the recovery time of all member resources, and a unit recovery time of the resource.
