MDM Engine Configuration File

A typical nme-config.xml file looks as follows:

nme-config.xml

<config>
	<persistenceLayers>
		<persistenceLayer class="com.ataccama.nme.persistence.database.DbPersistenceFactory">
			<dataSource>mdc_db</dataSource>
			<prefix>I_</prefix>
		</persistenceLayer>
	</persistenceLayers>

	<model>
		<models>
			<consolidation>
				<persistenceLayer class="com.ataccama.nme.persistence.vldb.VldbPersistenceFactory">
					<dataSource>mdc_db</dataSource>
					<prefix>C_</prefix>
				</persistenceLayer>
				<configFile>nme-model.gen.xml</configFile>
				<datasets>nme-datasets.gen.xml</datasets>
				<customActions>nme-custom-actions.gen.xml</customActions>
				<eventHandlersConfigFile>nme-event_handler.gen.xml</eventHandlersConfigFile>
				<executionPlanConfigFile>nme-consolidation-plan.xml</executionPlanConfigFile>
    			<enrichmentConfigFile>nme-enrichments.gen.xml</enrichmentConfigFile>
			</consolidation>
		</models>
	</model>

	<plugins>
        <plugin class="com.ataccama.nme.history.NmeHistoryPlugin">
            <persistenceLayer class="com.ataccama.nme.persistence.vldb.VldbPersistenceFactory">
                <dataSource>mdc_db</dataSource>
                <prefix>H_</prefix>
            </persistenceLayer>
            <configFile>nme-history.gen.xml</configFile>
            <storageDirectory>../storage/history</storageDirectory>
        </plugin>
    </plugins>
</config>

The paths are relative to the nme-config.xml file.

The main components (most of them configured in separate files) are:

Available plugins:

History plugin

Due to the broken compatibility after refactoring (see Ataccama 15.2.0 Release Notes, section Known Issues), the history plugin configuration defined in the nme-config.xml file is ignored in the current version, and all relevant properties are defined in the application.properties file. To learn more about the steps needed after the upgrade, see MDM 15.2.0 Upgrade Notes, section History plugin refactoring issue.

The issue will be resolved in 15.4.0. After version 15.4.0, definitions in the nme-config.xml file will be deprecated but still supported for a transitional period to maintain backward compatibility.
