Migrating from Talend Dictionary Service 6.x or 7.0.x installed with an external MongoDB

Before you begin

You have downloaded Talend Dictionary Service 7.3.x.

Procedure

  1. Stop your instance of the previous version of Talend Dictionary Service but keep MongoDB running.
  2. Backup your MongoDB, while it is still running, using the following command: mongodump -h <source_mongodb_host>:<source_mongo_port> -d <source_database> -u <source_mongodb_user> -p <source_mongodb_password> -o <dump_output>

    Example

    mongodump -h localhost:27017 -d dqdict -u dqdict-user -p duser -o dump\
  3. Stop your MongoDB instance.
  4. Install MongoDB 3.4.2 and start it.
    Talend Dictionary Service 7.3.x uses the 3.4.2 version of MongoDB.
  5. Restore MongoDB, open a command prompt window and execute the following command: <mongo_path>/bin/mongorestore -h <mongo_host>:<mongo_port> -u <mongo_dq_username> -p <mongo_dq_password> -d <mongo_dq_database> <backup_location>

    Example

    mongorestore -h localhost:27017 -d dqdict -u dqdict-user -p duser dump\
  6. Install Talend Dictionary Service 7.3.x with the external MongoDB, and configure it with the same settings as your instance of the previous version of Talend Dictionary Service, especially the links to your Talend Administration Center and point to MongoDB 3.4.2.
    For more information about the Talend Dictionary Service installation and configuration procedures, see the Talend Installation Guide.
  7. If you have performed any custom configuration to the previous version of the <Tomcat>/conf/data-quality.properties file, update the 7.3.x version of the file by coping the values from the old configuration file.
  8. Start Talend Dictionary Service 7.3.x by launching, in order:
    • Apache Zookeeper
    • Apache Kafka
    • Apache Tomcat (Talend Administration Center server and Talend Identity and Access Management server)
    • MongoDB

Results

You are now ready to use Talend Dictionary Service 7.3.x.
