Defining a Master Index Survivor Strategy for a Field or Object

To use a strategy for a specific field other than the strategy defined in the default-survivor-strategy element, you need to specify the new strategy for the appropriate candidate-field element. A candidate-field element can represent a field or child object. You do not need to specify a strategy for any fields that use the default survivor strategy.

To Define a Survivor Strategy for a Field

1. In the Projects window, expand the Configuration node in the project you want to modify, and then double-click update.xml.

   The file opens in the NetBeans XML editor.

2. Scroll to the candidate-definitions element in the SurvivorHelperConfig element.

3. In the candidate-field element for which you want to specify a new strategy, create a new survivor-strategy element.

   For example:

   <candidate-field name="Person.Alias[*].*"> <survivor-strategy> </survivor-strategy> </candidate-field>

4. In the new survivor-strategy element, create and name a new strategy-class element.

   Make sure to specify the fully qualified name of the Java class for the strategy. For example:

   <candidate-field name="Person.Alias[*].*"> <survivor-strategy> <strategy-class> com.sun.mdm.index.survivor.impl.UnionSurvivorStrategy </strategy-class> </survivor-strategy> </candidate-field>

   ---

   Note –

   To specify the default survivor strategy for a field, make sure the corresponding candidate-field element does not contain a survivor-strategy element. If you implement a custom strategy class, that class must be defined as a custom plug-in.

5. Save and close the file.
