DataWorks provides DM Reader and DM Writer for you to read data from and write data to Dameng (DM) data sources. You can use the codeless user interface (UI) or code editor to configure synchronization nodes for DM data sources. This topic describes how to add a DM data source.
PrerequisitesA resource group for Data Integration is created to run the synchronization nodes.
You must use a resource group for Data Integration to run the data synchronization nodes. When you add a DM data source, you must test the connectivity between the data source and the resource group to ensure that the resource group can connect to the data source. We recommend that you use an exclusive resource group for Data Integration. For more information, see Exclusive resource groups for Data Integration.
Background informationWorkspaces in standard mode support the data source isolation feature. You can add data sources separately for the development and production environments to isolate the data sources. This helps keep your data secure. For more information, see Isolate a data source in the development and production environments.
- Go to the Data Source page.
Note You can also go to the Data Sources page in Data Integration to add a data source. However, you can add a data source on the Data Sources page in Data Integration only to the production environment.
- Log on to the DataWorks console.
- In the left-side navigation pane, click Workspaces.
- In the top navigation bar, select the region in which the workspace you want to manage resides. On the Workspaces page, find the workspace, move the pointer over the icon in the Actions column, and then select Workspace Settings.
- In the left-side navigation pane of the page that appears, click Data Source to go to the Data Source page.
- On the Data Source page, click Add data source in the upper-right corner.
- In the Add data source dialog box, click DM in the Relational Database section.
- In the Add DM data source dialog box, configure the parameters.
Parameter Description Data Source Name The name of the data source. The name can contain letters, digits, and underscores (_) and must start with a letter. Data source description The description of the data source. The description can be a maximum of 80 characters in length. Environment The environment in which the data source is used. Valid values: Development and Production.Note This parameter is displayed only when the workspace is in standard mode. JDBC URL The Java Database Connectivity (JDBC) URL of the database, in the format of
User name The username that you use to connect to the database. Password The password that you use to connect to the database.
- Test the network connectivity.
- Click the Data Integration tab.
- Select the resource group that you want to use.
- We recommend that you use an exclusive resource group for Data Integration. If you do not have an exclusive resource group for Data Integration, you can click Create Exclusive Resource Group for Data Integration to purchase one by following the on-screen instructions.
- If you want to test the network connectivity between the shared resource group or a custom resource group and the data source, click Advanced below the resource group list. In the Warning message, click Confirm. Then, all available shared and custom resource groups appear in the resource group list.
- Find the resource group that you want to use and click Test connectivity in the Actions column. A synchronization node can use only one type of resource group. If you want to test the network connectivity between multiple types of resource groups and the data source, you can select the resource groups and click Batch test connectivity.
- If the data source passes the network connectivity test, click Complete.
