ABSTRACT:
Methods and mechanisms for preventing deadlock in a policy-based computer system are disclosed. In one embodiment, the method includes various machine-implemented steps, such as a step of receiving policy information based upon decisions about system configurations. At least one policy includes at least one action that has a post condition. Satisfaction of the post condition triggers at least one subsequent action or decision. The policy includes an indication whether the at least one subsequent action or decision should proceed if the action fails to satisfy the post condition. The at least one action is executed. Then, if the action fails to satisfy the post condition, a determination is made whether the at least one subsequent action or decision can proceed based upon the indication.
