GBase Connection Parameters

**Table 1** GBase connection
Parameter	Mandatory	Description
Data Connection Type	Yes	GBASE is selected by default and cannot be changed.
Name	Yes	Name of the data connection to create. Data connection names can contain a maximum of 100 characters. They can contain only letters, digits, underscores (_), and hyphens (-).
Description	No	A description which can help identify the data connection more easily. It can contain a maximum of 100 characters.
Tag	No	Attribute of the data connection to create. Tags make management easier. NOTE: The tag name can contain only letters, digits, and underscores (_) and cannot start with an underscore (_) or contain more than 100 characters.
Applicable Modules	Yes	Select the modules for which this connection is available. NOTE: When offline or real-time data migration jobs are enabled, you can select the DataArts Migration module. Then you can select this data connection when creating a data migration job in DataArts Factory. You can use offline or real-time data migration jobs only after you apply for the whitelist membership. 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 GBase data source. The value can be an IP address or a domain name.
Port	Yes	Port for accessing the relational database
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?. Only symmetric keys are supported. Asymmetric keys are not supported.
Agent	Yes	The CDM cluster provides an agent for communication between DataArts Studio and GBase. When creating a GBase connection, select a CDM cluster. If no CDM cluster is available, create one first by referring to Creating a CDM Cluster. NOTE: If a CDM cluster functions as the agent for a data connection in Management Center, the cluster supports a maximum of 200 concurrent active threads. If multiple data connections share an agent, a maximum of 200 SQL, Shell, and Python scripts submitted through the connections can run concurrently. Excess tasks will be queued. You are advised to plan multiple agents based on the workload.
Data Source Driver Configuration
Driver Name	Yes	Driver name com.gbase.jdbc.Driver: Select this driver name for GBASE8A.
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.

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.
