| Description | string | The central class used for representing the 'If Condition then Action' semantics of a policy rule. A PolicyRule condition, in the most general sense, is represented as either an ORed set of ANDed conditions (Disjunctive Normal Form, or DNF) or an ANDed set of ORed conditions (Conjunctive Normal Form, or CNF). Individual conditions may either be negated (NOT C) or unnegated (C). The actions specified by a PolicyRule are to be performed if and only if the PolicyRule condition (whether it is represented in DNF or CNF) evaluates to TRUE.
The conditions and actions associated with a PolicyRule are modeled, respectively, with subclasses of PolicyCondition and PolicyAction. These condition and action objects are tied to instances of PolicyRule by the PolicyConditionInPolicyRule and PolicyActionInPolicyRule aggregations.
A PolicyRule may also be associated with one or more policy time periods, indicating the schedule according to which the policy rule is active and inactive. In this case it is the PolicyRuleValidityPeriod aggregation that provides this linkage.
The PolicyRule class uses the property ConditionListType, to indicate whether the conditions for the rule are in DNF or CNF. The PolicyConditionInPolicyRule aggregation contains two additional properties to complete the representation of the Rule's conditional expression. The first of these properties is an integer to partition the referenced PolicyConditions into one or more groups, and the second is a Boolean to indicate whether a referenced Condition is negated. An example shows how ConditionListType and these two additional properties provide a unique representation of a set of PolicyConditions in either DNF or CNF.
Suppose we have a PolicyRule that aggregates five PolicyConditions C1 through C5, with the following values in the properties of the five PolicyConditionInPolicyRule associations:
C1: GroupNumber = 1, ConditionNegated = FALSE
C2: GroupNumber = 1, ConditionNegated = TRUE
C3: GroupNumber = 1, ConditionNegated = FALSE
C4: GroupNumber = 2, ConditionNegated = FALSE
C5: GroupNumber = 2, ConditionNegated = FALSE
If ConditionListType = DNF, then the overall condition for the PolicyRule is:
(C1 AND (NOT C2) AND C3) OR (C4 AND C5)
On the other hand, if ConditionListType = CNF, then the overall condition for the PolicyRule is:
(C1 OR (NOT C2) OR C3) AND (C4 OR C5)
In both cases, there is an unambiguous specification of the overall condition that is tested to determine whether to perform the PolicyActions associated with the PolicyRule.
PolicyRule instances may also be used to aggregate other PolicyRules and/or PolicyGroups. When used in this way to implement nested rules, the conditions of the aggregating rule apply to the subordinate rules as well. However, any side effects of condition evaluation or the execution of actions MUST NOT affect the result of the evaluation of other conditions evaluated by the rule engine in the same evaluation pass. That is, an implementation of a rule engine MAY evaluate all conditions in any order before applying the priority and determining which actions are to be executed. | None | TRANSLATABLE= true |
| Name | Data Type | Qualifiers |
| Name | Data Type | Value | Scope | Flavors |
| ConditionListType | uint16 |
| Description | string | Indicates whether the list of PolicyConditions associated with this PolicyRule is in disjunctive normal form (DNF) or conjunctive normal form (CNF).The default value is 1 ("DNF"). | None | TRANSLATABLE= true |
| ValueMap | string | 1, 2 | None | None |
| Values | string | DNF, CNF | None | TRANSLATABLE= true |
| CreationClassName | string |
| Description | string | CreationClassName indicates the name of the class or the subclass used in the creation of an instance. When used with the other key properties of this class, this property allows all instances of this class and its subclasses to be uniquely identified. | None | TRANSLATABLE= true |
| Key | boolean | true | None | OVERRIDABLE= false
|
| MaxLen | uint32 | 256 | None | None |
| Enabled | uint16 |
| Description | string | Indicates whether this PolicyRule is administratively enabled, administratively disabled, or enabled for debug. When the property has the value 3 ("enabledForDebug"), the entity evaluating the PolicyConditions is instructed to evaluate the conditions for the Rule, but not to perform the actions if the PolicyConditions evaluate to TRUE. This serves as a debug vehicle when attempting to determine what policies would execute in a particular scenario, without taking any actions to change state during the debugging. The default value is 1 ("enabled"). | None | TRANSLATABLE= true |
| ValueMap | string | 1, 2, 3 | None | None |
| Values | string | enabled, disabled, enabledForDebug | None | TRANSLATABLE= true |
| ExecutionStrategy | uint16 |
| Description | string | ExecutionStrategy defines the strategy to be used in executing the sequenced actions aggregated by this PolicyRule. There are three execution strategies:
Do Until Success - execute actions according to predefined
order, until successful execution of a
single action.
Do All - execute ALL actions which are part of
the modeled set, according to their
predefined order. Continue doing this,
even if one or more of the actions fails.
Do Until Failure - execute actions according to predefined
order, until the first failure in
execution of an action instance. | None | TRANSLATABLE= true |
| ValueMap | string | 1, 2, 3 | None | None |
| Values | string | Do Until Success, Do All, Do Until Failure | None | TRANSLATABLE= true |
| Mandatory | boolean |
| Description | string | A flag indicating that the evaluation of the PolicyConditions and execution of PolicyActions (if the Conditions evaluate to TRUE) is required. The evaluation of a PolicyRule MUST be attempted if the Mandatory property value is TRUE. If the Mandatory property is FALSE, then the evaluation of the Rule is 'best effort' and MAY be ignored. | None | TRANSLATABLE= true |
| PolicyRuleName | string |
| Description | string | A user-friendly name of this PolicyRule. | None | TRANSLATABLE= true |
| Key | boolean | true | None | OVERRIDABLE= false
|
| MaxLen | uint32 | 256 | None | None |
| Priority | uint16 |
| DEPRECATED | string | CIM_PolicySetComponent.Priority | None | None |
| Description | string | PolicyRule.Priority is deprecated and replaced by providing the priority for a rule (and a group) in the context of the aggregating PolicySet instead of the priority being used for all aggregating PolicySet instances. Thus, the assignment of priority values is much simpler.
A non-negative integer for prioritizing this PolicyRule relative to other Rules. A larger value indicates a higher priority. The default value is 0. | None | TRANSLATABLE= true |
| RuleUsage | string |
| Description | string | A free-form string that can be used to provide guidelines on how this PolicyRule should be used. | None | TRANSLATABLE= true |
| SequencedActions | uint16 |
| Description | string | This property gives a policy administrator a way of specifying how the ordering of the PolicyActions associated with this PolicyRule is to be interpreted. Three values are supported:
o mandatory(1): Do the actions in the indicated order, or don't do them at all.
o recommended(2): Do the actions in the indicated order if you can, but if you can't do them in this order, do them in another order if you can.
o dontCare(3): Do them -- I don't care about the order.
The default value is 3 ("dontCare"). | None | TRANSLATABLE= true |
| ValueMap | string | 1, 2, 3 | None | None |
| Values | string | mandatory, recommended, dontCare | None | TRANSLATABLE= true |
| SystemCreationClassName | string |
| Description | string | The scoping System's CreationClassName. | None | TRANSLATABLE= true |
| Key | boolean | true | None | OVERRIDABLE= false
|
| MaxLen | uint32 | 256 | None | None |
| Propagated | string | CIM_System.CreationClassName | None | OVERRIDABLE= false
|
| SystemName | string |
| Description | string | The scoping System's Name. | None | TRANSLATABLE= true |
| Key | boolean | true | None | OVERRIDABLE= false
|
| MaxLen | uint32 | 256 | None | None |
