Possible Causes

When you create a migration job to DLI on the CDM console, you set Resource Queue to a DLI queue for general purpose. It should be a queue for SQL.

Solution

1. On the DLI management console and click Queue Management in the navigation pane on the left. On the Queue Management page, check whether there are SQL queues.
   • If there are, go to 3.
   • If there are no SQL queues, go to 2 to buy an SQL queue.
2. Click Buy Queue to create a queue. Set Type to For SQL, set other parameters required, and click Buy.
3. Go back to the CDM console and create a data migration job. Set Resource Queue to the created DLI SQL queue.
4. Submit the migration job and view the job execution logs.
