Installation and Upgrade
Once you back up Talend Dictionary Service, you can recover the data at any time and have an exact copy of the backed up instance.


  1. Stop your Talend Dictionary Service instance.
    You can do the backup while the instance is running, but you are advised to choose a period of low activity.
  2. Launch MongoDB.
  3. Open a command prompt window and execute the below command to delete the database in the current instance of the Dictionary service:
    <path_to_installation_folder>/mongodb/bin/mongo <dbname>  -u <userName> -p <userPassword> --eval "db.dropDatabase()"
    If you installed Talend Data Stewardship with the Dictionary service using Talend Installer, the command reads as follows:
    <path_to_installation_folder>/mongodb/bin/mongo dqdict -u dqdict-user -p duser --eval "db.dropDatabase()"
  4. Replace the dump folder of the current instance stored at <path_to_installation_folder>/dq_dict/database/ with the dump folder you get from the back up procedure.
  5. From a command prompt window, execute the command to import the backup directory of the Dictionary service named dump. Use .bat or .sh according to your system, for example
  6. To restore your configuration, replace the content of the <path_to_installation_folder>/dq_dict/apache-tomcat/conf folder with your backed up copy.


The Dictionary service instance is recovered.
