DataV

Procedure

1. Connect DataV to a Hologres instance.

   You can connect DataV to a Hologres instance in three ways: over a virtual private cloud (VPC), the internet, or a classic network. For more information about these network types, see Instance details. We recommend connecting over a VPC.

   Note

   To connect to a Hologres instance over a VPC, first bind the instance to a specific VPC. This generates a VPC endpoint. For more information, see Instance details.

   1. Log on to the DataV console . In the left-side navigation pane, click Data Sources. On the Data Sources page, click Add Source.

   2. In the Add Data Source dialog box, configure the parameters based on your network type, and then click OK. For example, to connect over a classic network, set Type to Hologres and Network to intranet. Select a Region such as China (Shenzhen). Then, turn off the VPC switch, and specify the Name, classic network endpoint, Username, Password, and Port. In the Database field, click Get Data List and select the target database.
