The Handler has to be registered in the solrconfig.xml as follows.

<requestHandler name="/dataimport" class="org.apache.solr.handler.dataimport.DataImportHandler">
    <lst name="defaults">
      <str name="config">/home/username/data-config.xml</str>
    </lst>
  </requestHandler>

he configuration is provided in two places:

solrconfig.xml . The data config file location is added here
The datasource also can be added here. Or it can be put directly into the data-config.xml
data-config.xml
- How to fetch data (queries,url etc)
- What to read ( resultset columns, xml fields etc)
- How to process (modify/add/remove fields)

Using query attribute for both full and delta import
