To use this feature, contact customer service or technical support.
Basic and Network Connectivity Configuration
IP Address or Domain Name	Yes	Address for accessing the relational database data source. The value can be an IP address or a domain name. If the data source is RDS or GaussDB, you can obtain the address on the management console by performing the following operations: Log in to the management console of the corresponding cloud service using the account you have obtained. In the left navigation pane, choose Instances. Click the name of an instance to enter the basic information page. In the Connection Information area, you can obtain the private IP address, domain name, and port number. NOTE: Only the GaussDB data source supports multiple domain names. Use commas (,) to separate multiple domain names. If the data source is MySQL, PostgreSQL, or DM, you can obtain the access address from the database administrator.
Port	Yes	Port for accessing the relational database If the data source is RDS or GaussDB, you can obtain the address on the management console by performing the following operations: Log in to the management console of the corresponding cloud service using the account you have obtained. In the left navigation pane, choose Instances. Click the name of an instance to enter the basic information page. In the Connection Information area, you can obtain the private IP address, domain name, and port number. NOTE: Only the GaussDB data source supports multiple domain names. Use commas (,) to separate multiple domain names. If the data source is MySQL, PostgreSQL, or DM, you can obtain the access address from the database administrator.
KMS Key	Yes	KMS key used to encrypt and decrypt data source authentication information. Select a default or custom key. NOTE: When you use KMS for encryption through DataArts Studio or KPS for the first time, the default key dlf/default or kps/default is automatically generated. For more information about default keys, see What Is a Default Master Key?.
Agent	Yes	DataArts Studio cannot be directly connected to non-fully managed services. A CDM cluster can provide an agent for DataArts Studio to communicate with non-fully-managed services. Therefore, you need to select a CDM cluster when creating a SAP HANA data connection. If no CDM cluster is available, create one first by referring to Creating a CDM Cluster.
Data Source Driver Configuration
Driver Name	Yes	Driver name com.mysql.jdbc.Driver: Select this driver name for RDS for MySQL or MySQL. org.postgresql.Driver: Select this driver name for RDS for PostgreSQL or PostgreSQL. com.microsoft.sqlserver.jdbc.SQLServerDriver: Select this driver name for RDS for SQL Server. dm.jdbc.driver.DmDriver: Select this driver name for the Dameng database. com.huawei.opengauss.jdbc.Driver: Select this driver name for RDS for GaussDB.
Driver Source	Yes	Source of the driver file
Driver File Path	Yes	This parameter is mandatory when Driver File Source is set to OBS path. It specifies the OBS path where the driver file is located. You need to download a .jar driver file from the corresponding official website and upload it to OBS. MySQL driver: Download it from https://downloads.mysql.com/archives/c-j/. The 5.1.48 version is recommended. PostgreSQL driver: Download it from https://mvnrepository.com/artifact/org.postgresql/postgresql. The 42.3.4 version is recommended. SQL Server driver: Download it from https://learn.microsoft.com/en-us/sql/connect/jdbc/download-microsoft-jdbc-driver-for-sql-server?view=sql-server-ver16. The 8.4.1 version is recommended. Dameng database driver: Obtain DmJdbcDriver18.jar from the DM installation directory /dmdbms/drivers/jdbc. GaussDB driver: Search for "JDBC Package, Driver Class, and Environment Class" in GaussDB User Guide in the GaussDB Documentation, select the document corresponding to the instance version, and obtain the driver package by referring to the document. NOTE: The OBS path of the driver file cannot contain Chinese characters. To update the driver, you must restart the CDM cluster in DataArts Migration and then edit the data connection to upload the driver.
Driver File	Yes	This parameter is mandatory when Driver Source is set to Local file. You can download a driver file from the official driver website, and then click Select and upload the driver. Alternatively, you can select a driver that has been uploaded before.
