Before you begin
You have downloaded Talend Dictionary Service 8.0.
Procedure
- 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.
-
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\
-
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,
especially the links to your Talend Administration Center and
point to MongoDB 4.4.
For more information about the Talend Dictionary Service installation and configuration procedures, see the Talend Installation Guide.
- Open the previous version of the <Tomcat>/conf/data-quality.properties file and the new version.
-
In the new version of the data-quality.properties file,
replace the following parameter names with the new names:
Previous parameter name New parameter name dq.mongo.host spring.data.mongodb.host dq.mongo.port spring.data.mongodb.port dq.mongo.username spring.data.mongodb.username dq.mongo.password spring.data.mongodb.password dq.mongo.database.name spring.data.mongodb.database dq.mongo.ssl.enabled spring.data.mongodb.ssl dq.mongo.ssl.trust-store spring.data.mongodb.ssl.trust-store dq.mongo.ssl.trust-store-password spring.data.mongodb.ssl.trust-store-password - 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.
