Turn on Distributed Cache Refresh in IOS

Note: If the parameter in the iosconfig.xml file is set to disabled, only the cluster server member that received the refresh invocation will be refreshed, leaving the other machines out-of-sync.
  1. Navigate to $LAWDIR/system.
  2. With a text editor, open the iosconfig.xml file.
  3. Enable the following entry: 
    <parameter name="com.lawson.servlet.ioscacherefresh.clusterrefresh" value="enabled"/>
    Note: Add the entry if it doesn't exist.
  4. Save and close the file.
  5. Restart the cluster.
