2.6.2. Import mode

In this section, the following modes for the import strategy are introduced:

Each mode indicates how the Portal data are imported. The import mode value is set whenever NewPortalConfigListener is initiated. If the mode is not set, the default value will be used in this case. The default value is configurable as a UserPortalConfigService initial param. For example, the bellow configuration means that default value is MERGE.


<component>
  <key>org.exoplatform.portal.config.UserPortalConfigService</key>
  <type>org.exoplatform.portal.config.UserPortalConfigService</type>
  <component-plugins>
  ............
  </component-plugins>
  <init-params>
    <value-param>
      <name>default.import.mode</name>
      <value>merge</value>
    </value-param>
  </init-params>
</component>

The way that the import strategy works with the import mode will be clearly demonstrated in next sections for each type of data.
