How do I renew a resource group?

Log on to the DataWorks console. Click Resource Groups in the left-side navigation pane. On the Resource Groups page, find the resource group that you want to renew and click Renew in the Actions column.
Note
  • If you want to use a RAM user to renew a resource group, you must grant the required permissions to the RAM user. .
  • If you want to switch the renewal method of the resource group between manual renewal and auto renewal, you can perform the operation on the Renewal Management page based on the instance name of the resource group.

How do I change the specifications of an exclusive resource group? How do I scale in or out an exclusive resource group?

Log on to the DataWorks console. Click Resource Groups in the left-side navigation pane. The Exclusive Resource Groups tab appears. On the Exclusive Resource Groups tab, find the desired exclusive resource group and click Scale Out, Scale In, or Change Specifications in the Actions column to perform the related operation.
Note
  • If you want to use a RAM user to perform the preceding operations, you must grant the required permissions to the RAM user.
  • If you scale in or out a resource group, the number of resources in the resource group is decreased or increased.

What conditions must be met before an exclusive resource group can access a data source that resides in a VPC?

If you want to use an exclusive resource group to access a data source that resides in a VPC in DataWorks, the following conditions must be met:
  • The exclusive resource group resides in the same zone as the data source and is associated with a VPC.
  • The exclusive resource group is associated with the same VPC and vSwitch as the data source.
  • If the data source is configured with a whitelist or security group, the elastic IP address (EIP) of the exclusive resource group or the Classless Inter-Domain Routing (CIDR) block of the VPC or vSwitch with which the exclusive resource group is associated is added to the whitelist or security group. For more information, see Configure a whitelist and Configure a security group for an ECS instance where a self-managed data store resides.

How do I view the network environment of a data source?

  • If you want to view the network environment of an ApsaraDB RDS data source, perform the following steps:
    1. Log on to the ApsaraDB RDS console.
    2. In the left-side navigation pane, click Instances. On the Instances page, find the instance whose network environment you want to view and click the instance name to go to the details page of the instance.
    3. In the left-side navigation pane of the instance details page, click Database Connection.
