Managing a Single Job¶
Existing CDM jobs can be viewed, modified, deleted, started, and stopped. This section describes how to view and modify a job.
Viewing a Job¶
Viewing job status
The job status can be New, Pending, Booting, Running, Failed, or Succeeded.
Pending indicates that the job is waiting to be scheduled by the system, and Booting indicates that the data to be migrated is being analyzed.
Viewing the historical records
On the Historical Record page, you can view job execution records, read/write statistics, and job execution logs.
Viewing job logs
On the Historical Record page, you can view all logs of a job.
Alternatively, in the Operation column, choose More > Log to view the latest logs of the job.
Viewing the JSON file of a job
You can directly edit the JSON file of a job, which is equivalent to modifying the parameter settings of the job.
Querying the job statistics
You can open the preview window of a configured database job and view up to 1,000 pieces of data. By comparing the number of data records of the migration source and destination, you can check whether the migration was successful and whether data was lost.
Viewing historical jobs
CDM stores the jobs executed in the last month, including one-time jobs (jobs that are automatically deleted after execution) and jobs that are executed periodically. You can view and re-execute the jobs on the Historical Jobs tab page.
For a job that is executed periodically, a historical job is generated on the Historical Jobs tab page each time when the job is executed, regardless of whether the job is executed successfully. The names of historical jobs will be the same as the original job but with a random character string appended.
Modifying a Job¶
Modifying the job parameters
You can reconfigure job parameters, but you cannot reselect source and destination links.
Editing the JSON file of a job
You can directly edit the JSON file of a job, which is equivalent to modifying the parameter settings of the job.
Procedure¶
Log in to the management console and choose Service List > Cloud Data Migration. In the left navigation pane, choose Cluster Management. Locate the target cluster and click Job Management.
Click Historical Jobs to view all historical jobs executed in the latest month.

Modify the job parameters: Click Edit in the Operation column to modify the job parameters.
Run the job: Click Run in the Operation column to manually start the job.

Delete the job: Choose More > Delete in the Operation column to delete the job.
Stop the job: Choose More > Stop in the Operation column to stop the job.
View the job JSON: Choose More > View Job JSON in the Operation column to view the job JSON.
Edit the job JSON: Choose More > Edit Job JSON in the Operation column to edit the job JSON files, which is similar to modify the job parameters.
Configure a scheduled job: Locate a job and choose More > Configure Scheduled Execution. You can set the cycle for periodically executing the job. For details, see Scheduling Job Execution.
After the modification, click Save or Save and Run.
