Data Transmission Service (DTS) allows you to use Resource Access Management (RAM) to manage permission policies. You can create and manage tasks as a RAM user. You can also track data changes in real time by using the AccessKey ID and AccessKey secret of the RAM user.


A RAM user is authorized to access the cloud resources (such as RDS instances and ECS instances) of the current Alibaba Cloud account. When you configure a DTS task as the RAM user, DTS is allowed to call the relevant cloud resource information. For more information, see Authorize DTS to access Alibaba Cloud resources.

Permission policies

DTS supports read/write and read-only policies.

  • Read/write policy: AliyunDTSFullAccess

    This policy grants the read and write permissions on DTS. If this policy is attached to a RAM user, the RAM user can purchase, configure, and manage DTS instances.

  • Read-only policy: AliyunDTSReadOnlyAccess This policy grants the read permissions on DTS. If this policy is attached to a RAM user, the RAM user can view the details and configurations of all DTS tasks owned by the Alibaba Cloud account. However, the RAM user cannot perform change operations.
    Note Change operations include the purchase, configuration, and management of DTS instances.

Track data changes as a RAM user

After you create a RAM user and grant the required permissions to the RAM user, you can use the SDK provided by DTS to track data changes. For more information about how to use the DTS SDK, see Use the SDK demo code to consume tracked data.
Note You must replace the sample AccessKey pair in the SDK demo with the AccessKey pair of your RAM user.
