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()"
- 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.
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
