CDM Job

Functions

The CDM Job node is used to run a predefined CDM job for data migration.

If you have configured a macro variable of date and time in a CDM job and schedule the CDM job through DataArts Factory, the system replaces the macro variable of date and time with (Planned start time of the data development job – Offset) rather than (Actual start time of the CDM job – Offset).

Parameters

Table 1, Table 2, and Table 3 describe the parameters of the CDM Job node. Configure the lineage to identify the data flow direction, which can be viewed in the DataArts Catalog module.

**Table 1** Parameters of CDM Job nodes
Parameter	Mandatory	Description
CDM Cluster Name	Yes	Name of the CDM cluster to which the CDM job to be executed belongs. You can select two CDM clusters to improve job reliability. If you select two clusters, the first one is the active cluster, and the second one is the standby cluster. Jobs run on the active cluster by default. If the active cluster is abnormal, jobs are migrated to the standby cluster. If you select two clusters, you are advised to set Job Type to Existing jobs rather than New jobs and ensure that the job exists in both the active and standby clusters. You can create a CDM job in the active cluster, export it, and import it to the standby cluster to implement job synchronization. For details, see Exporting and Importing CDM Jobs in Batches.
Job Type	Yes	Existing jobs New jobs NOTE: If Job Type is Existing jobs, the job node is not updated when the CDM job is modified. To update the job node, save the job where the node is located again to trigger a CDM job update. If Job Type is New jobs, the system checks whether a CDM job with the same name is running. If the CDM job is not running, update the job with the same name based on the request body. If a CDM job with the same name is running, update the job after the job is run. During this period, the job may be started by other tasks. As a result, the extracted data may not be the same as expected (for example, the job configuration is not updated, or the macro of the running time is not correctly replaced). Therefore, do not create multiple jobs with the same name.
CDM Job Name	No	This parameter is required only when Job Type is set to Existing jobs. Name of the CDM job to be executed. If the CDM job uses the job parameters or environment variables configured during data development, data can be indirectly migrated based on the parameters or variables during node scheduling in the DataArts Factory module.
CDM Job Message Body	No	This parameter is required only when Job Type is set to New jobs. Enter the JSON message body of the CDM job. For convenience, you can choose More > View Job JSON in the Operation column of an existing CDM job, copy the JSON content, and modify the content here. If the CDM job uses the job parameters or environment variables configured during data development, data can be indirectly migrated based on the parameters or variables during node scheduling in the DataArts Factory module.
Node Name	Yes	Name of a node. The name must contain 1 to 128 characters, including only letters, numbers, underscores (_), hyphens (-), slashes (/), less-than signs (<), and greater-than signs (>).

**Table 2** Advanced parameters
Parameter	Mandatory	Description
Node Status Polling Interval (s)	Yes	Specifies how often the system check completeness of the node task. The value ranges from 1 to 60 seconds.
Max. Node Execution Duration	Yes	Execution timeout interval for the node. If retry is configured and the execution is not complete within the timeout interval, the node will not be retried and is set to the failed state.
Retry upon Failure	Yes	Whether to re-execute a node if it fails to be executed. Yes: The node task will be re-executed, and the following parameters must be configured: Maximum Retries Retry Interval (seconds) No: The node will not be re-executed. This is the default setting. NOTE: If Max. Node Execution Duration is configured for the node, the node will not be executed again after the execution times out. Instead, the node is set to the failure state. If parameter transfer is used for scheduling the CDM job, do not configure parameter Retry upon Failure in the CDM job.
Failure Policy	Yes	Operation that will be performed if the node fails to be executed. Possible values: End the current job execution plan: stops running the current job. The job instance status is Failed. Go to the next node: ignores the execution failure of the current node. The job instance status is Failure ignored. Suspend current job execution plan: suspends running the current job. The job instance status is Waiting. Suspend execution plans of the subsequent nodes: stops running subsequent nodes. The job instance status is Failed.
Dry run	No	If you select this option, the node will not be executed, and a success message will be returned.
