ABSTRACT:
A context-sensitive pre-evaluation analysis of a set of rules is performed based on the circumstance or the current state of a rule clause directed to an infrequently changing condition. A group of multiple-clause rules are identified which each have a clause defining an infrequently changing condition for evaluating a state of a resource. The current state of the resource is monitored. If the identified group of multiple-clause rules, which cannot evaluate as TRUE under the context of the current state the resource, the identified group of multiple-clause rules are excluded from consideration by the rules engine. The rules engine will then encounter fewer rules to evaluate for a solution. The identified group of multiple-clause rules is further analyzed in the context of the infrequently changing condition for the current resource state. State metrics that are defined by clauses of the identified multiple-clause rules, those that cannot evaluate as TRUE, are identified. Those metrics are then also excluded from consideration by the rules engine. Thus, the rules engine will encounter fewer rules and/or event states that cannot be evaluated to a solution. The context-sensitive pre-evaluation analysis of the rules is performed out-of-band as the rules engine traverses the rule.
