Working with CA Catalyst Reconciliation › How to Perform CA Catalyst Reconciliation › Change Individual Property Formulas

Change Individual Property Formulas

You specify the default reconciliation formula in the ssaserver.xml file. The defaultsheet.xml file lets you set different reconciliation formulas for specific properties. Property-specific formulas override the default for that property.

For example, consider a situation where CA Spectrum is the preferred domain manager for maintenance information. If the default formula is FirstNonNullValueWinsFormula, you may want to set the formula for the IsInMaintenance property to always use the property retrieved from CA Spectrum.

Follow these steps:

1. Access the CA Catalyst Registry.
2. Navigate to the following location: /topology/physical/node0/reconciler/defaultsheet.xml.
3. Click Edit as text.

   Notice that several properties already have specific formulas applied, such as MdrProduct and MdrElementID. Do not change the formulas for these properties.

4. Use the following line to define a property-specific formula and click Save Content:

   <formulaRecord input="" name="" cellName=""/>
   

   cellName

   Defines the name of the USM property to which to apply the specific reconciliation formula.

   name

   Defines the name of the reconciliation formula to apply when reconciling the specified property. This attribute requires only the formula name, such as NoOpFormula.

   input

   Defines input parameters for any formula that requires them. Currently, only SingleSourceOfTruthFormula requires input. For all other formulas, enter an asterisk (*) for the input.

Example: Set cell-specific formula for IpAddress

This example sets the reconciliation formula for the IpAddress property to NoOpFormula, so that the Reconciler does not perform any calculations on this property:

<formulaRecord input="*" name="NoOpFormula" cellName="IpAddress"/>
