Before You Create the Data Preparation Service
Before you create the Data Preparation Service, complete the prerequisite tasks for the service.
Perform the following tasks before you create the Data Preparation Service, if Oracle is the database for the Data Preparation Service Repository:
- •Set up the Oracle server database version 12cR2 or 11gR2 that the Data Preparation Service connects to. Ensure that the database is case insensitive.
- •Set up the required user account for the Oracle database with create, drop, and alter permissions for tables and views.
Perform the following tasks before you create the Data Preparation Service, if MySQL is the database for the Data Preparation Service Repository:
- •Set up the MySQL server database version 5.6.26 or above that the Data Preparation Service connects to. Ensure that the database is case insensitive. For MySQL version 5.6.26 and above, set lower_case_table_names=1 and for MySQL version 5.7 and above, set explicit_defaults_for_timestamp=1 in the my.cnf file.
- •Set up the required user account for the MySQL database with create, drop, and alter permissions for tables and views.
If the domain is secure, you must secure the services that you create in Intelligent Data Lake.
- •The following services in the domain and the YARN application must share the same common truststore file:
- - Data Integration Service
- - Model Repository Service
- - Catalog Service
- - Data Preparation Service
- - Intelligent Data Lake Service
- •The Data Preparation Service and Intelligent Data Lake Service must also share the same keystore file.
- •You can use different keystore files for the Data Integration Service, Model Repository Service, and Catalog Service. If you use different keystore files, you must add certificates corresponding to each of the keystores into a common truststore file.
- •If you have configured Intelligent Data Lake with one primary node and one or more backup nodes, you must copy the truststore files to a common directory and specify the same directory path for all nodes assigned to Intelligent Data Lake.
