Before you begin
You have downloaded the latest hybrid Talend Dictionary Service
8.0 archive from Talend Cloud's
Downloads page.
Procedure
-
Open Talend Data Inventory, Talend Data Preparation or Talend Data Stewardship.
-
Go to the Semantic types tab.
-
Export the semantic types you want to keep.
Important: Exporting and reimporting your
semantic types is critical to avoid losing existing semantic types.
-
Stop your instance of the previous version of Talend Dictionary Service but keep MongoDB
running.
-
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\
-
Stop your MongoDB instance.
-
Install MongoDB 4.4 and start it.
Talend Dictionary Service 8.0 uses the 4.4 version of MongoDB.
-
Install Talend Dictionary Service 8.0 with the external MongoDB, and configure it with the same settings as
your instance of the previous version of Talend Dictionary Service which points to MongoDB 4.4.
-
If you have performed any custom configuration to the previous version of the
data-quality.properties file, update the 8.0 version of the
file by coping the values from the old configuration file. You can
then change parameters needed for Talend Cloud
and Talend Management Console.
-
Open Talend Data Inventory, Talend Data Preparation or Talend Data Stewardship.
-
Go to the Semantic types tab.
-
Import the previously exported semantic types.
