Configuring impact normalization rules

BMC Atrium CMDB provides out-of-the-box impact rules that the Normalization Engine uses to populate the HasImpact and ImpactDirection attributes for relationships in all datasets. You can also create additional rules for populating the ImpactWeight and ImpactPropagationModel attributes for relationships based on your requirements.

For more information about out-of-the-box impact rules, see Normalization and impact relationships.

Important

Although you can edit or delete the out-of-the-box impact rules that are shipped with the product, BMC recommends that you do not edit or delete these rules. Other BMC products that consume the configuration data in BMC Atrium CMDB reference the out-of-the-box impact rules, and editing or deleting these rules can result in errors in these products.

To create an impact normalization rule

  1. In the Normalization console, click Normalization Features.
  2. In the Impact tab, click Create New Rule.
  3. In the New Impact Rule dialog box, configure the following parameters:
    • Active — Click to activate the rule so that the Normalization Engine can apply the rule on datasets for which the Impact Normalization feature is enabled.
    • Rule Name — Enter a descriptive name for the rule.
  4. On the Conditions tab, configure the following parameters:
    • Class Name — Select the relationship class for which you want to create an impact rule.
    • (Optional) Apply to Subclasses — Select this check box if you want to apply the rule to all subclasses of the selected relationship class.
    • (Optional) Qualifier — Type the qualification or click .

      Use BMC Remedy AR System qualifications to define the CIs or relationships to which the custom rule applies. For information about using the Qualification Builder, see Building a qualification for a reconciliation activity.
  5. In the Relationship Details area, configure the following parameters:
    • Source CI Class — Select the parent class in the relationship.
    • Destination CI Class — Select the child class in the relationship.
    • (Optional) Apply to Subclasses — Select this check box if you want to apply the rule to all subclasses of the source and destination CI classes.
    • (Optional) Qualifier — Type the qualification or click .

      Use BMC Remedy AR System qualifications to define the CIs or relationships to which the custom rule applies. For information about using the Qualification Builder, see Building a qualification for a reconciliation activity.
  6. On the Action tab, specify the values that the Normalization Engine should apply to the impact attributes (HasImpact, ImpactDirection, ImpactWeight and ImpactPropagationModel ) of the relationship.
    For information about the impact attributes, see the BMC Atrium CMDB Data Model Help.
  7. To save the impact rule, click OK.

To edit an impact normalization rule

  1. In the Normalization console, click Normalization Features.
  2. In the Impact tab, select a relationship rule and click Edit Selected Rule.
  3. In the Edit Impact Rule dialog box, modify the parameters that you have specified for the impact rule.

    Note

    You cannot modify the class name of an existing impact rule.

  4. To save changes, click OK.

To delete an impact normalization rule

  1. In the Normalization console, click Normalization Features.
  2. In the Impact tab, select an impact rule and click Delete Selected Rule.
  3. To delete the impact rule, click OK in the Delete Impact Rule dialog box.

To enable or disable impact rules for a dataset

  1. In the Normalization console, click Edit Configuration.
  2. In the Normalization Features column on the Dataset Configuration tab, click the ... button.
  3. In the Configure Normalization Features dialog box, click the check box to enable or disable the Impact Normalization feature.

    Note

    Only rules that are active are executed.

    You can also edit an additional parameter that will affect the Impact Normalization feature. The additional normalization impact mode settings are given below:

    Auto Impact Manual Edit

    Preserve Manual Edits

    (Default) Retains any manual edits that you have made to the HasImpact andImpactDirection impact attributes of the relationship instances, instead of reapplying the values that are defined in the best-practice impact normalization rules. 

    For more information about the best-practice relationship instances, see Normalization and impact relationships.

    Apply Rule Always

    Overwrites any manual edits that you have made to the HasImpact andImpactDirection impact attributes of the relationship instances with the values that are defined in the best-practice impact normalization rules. 

    For more information about the best-practice relationship instances, see Normalization and impact relationships.

  4. Click OK.
