If you are using LTU Engine Server then you will have to update your license file every years. When you have download your license file from our DownloadCenter please follow theses steps:

  • Switch to user 'ltu':
su - ltu
  • Backup your old license file:
cp config/license.lic config/license.old
  • Add new license file:
cp /tmp/MY_NEW_LICENSE_FILE config/license.lic
  • Restart the license server:
ltud restart license


Everything should then be updated, please proceed to a few queries to test system status.
