Abstract

Resources are checkpointed in order to save the state of the resources. The resources can then be brought back to the same running state, during a restart procedure, by making use of the saved state. The determination of when to take a checkpoint or when to restart a resource is made by an entity, such as a cluster manager, external to the entity initiating or taking the checkpoint or performing the restart. The decision to checkpoint/restart a resource is provided by the cluster manager to a resource manager associated with the resource. This communication is facilitated by interfaces to the cluster manager provided by the resource manager.
