Manage and run manually triggered nodes - DataWorks - Alibaba Cloud Documentation Center

After you deploy a manually triggered workflow to the production environment, you can manually trigger the nodes in the workflow to run on the Manual Task page of Operation Center. You can view the details of and perform the required operations on a manually triggered node in the list of manually triggered nodes or in the directed acyclic graph (DAG) of the current manually triggered workflow.

Note

After a manually triggered workflow is committed to the scheduling system, the nodes in the workflow are not automatically run. You can only manually trigger the nodes to run. For more information, see Create a manually triggered task.
Manually triggered nodes that are created in DataWorks V1.0 are listed as nodes of the Manually Triggered Node type, and manually triggered nodes that are created in DataWorks V2.0 or later are listed as nodes of the Manually Triggered Workflow type.

Go to the Manual Task page

Log on to the DataWorks console. In the top navigation bar, select the desired region. In the left-side navigation pane, choose Data Development and Governance > Operation Center. On the page that appears, select the desired workspace from the drop-down list and click Go to Operation Center.
In the left-side navigation pane of the Operation Center page, choose Manually Triggered Node O&M > Manual Triggered Nodes.

Manage manually triggered nodes in the node list

All the manually triggered nodes that are deployed are displayed in the node list.

Operation	Description
Filter	Allows you to specify conditions to search for the desired manually triggered node in the area marked with 1 in the preceding figure. You can search for a manually triggered node by specifying the following conditions: Workflow, Node, Owner, My Nodes, and Modified Today. Note The search result that is returned when you search for a manually triggered node by node name is affected by other conditions that you specify. Only the manually triggered nodes that meet all conditions are displayed.
DAG	Allows you to view the DAG of the current manually triggered workflow. You can view information such as the code and lineage of the manually triggered workflow in the DAG. For more information, see Manage manually triggered nodes in a DAG.
Run	Find the desired manually triggered node and click Run in the Actions column. In the Run dialog box, configure the parameters and click Run. The Operating range parameter specifies the operation scope, which triggers the system to generate manually triggered node instances. Range: Specifies whether to run all manually triggered nodes or only specified manually triggered nodes in the workflow. Data Timestamp: Specifies the data timestamp range of the manually triggered nodes. You can click Add Multiple Data Timestamp Ranges to add multiple data timestamp ranges. You can select a date in the past or in the future to filter manually triggered nodes. Note If you click Add Multiple Data Timestamp Ranges to add multiple data timestamp ranges, the system runs manually triggered nodes based on the specified data timestamp ranges in chronological order. Workflow Parameters: If you configure workflow parameters for a manually triggered workflow that you develop, you must assign values to the workflow parameters when you run all manually triggered nodes in the workflow. For more information, see Use workflow parameters. Order: specifies whether to run manually triggered nodes based on the data timestamp range in chronological order or reverse chronological order. Note If you manage manually triggered nodes in the node list, you can select to run all manually triggered nodes in the workflow when you click Run. The nodes for which you configure scheduling dependencies in the workflow are run based on the scheduling dependencies. The nodes for which you do not configure scheduling dependencies in the workflow are run in parallel.
View Instances	Allows you to go to the Manual Instance page to view the manually triggered node instances that are generated for the node. For more information, see View and manage manually triggered node instances.
More	Allows you to perform other operations on the manually triggered node. You can click More in the Actions column of the manually triggered node and select an operation. The operations include Change Owner, Modify Scheduling Resource Group, and Undeploy Manually Triggered Workflow.
Batch operations	Allows you to select multiple manually triggered nodes and perform the following operations in the area marked with 3 in the preceding figure: Change Owner, Modify Scheduling Resource Group, and Undeploy Manually Triggered Workflow.

Manage manually triggered nodes in a DAG

To view the DAG of a manually triggered workflow, click the name of the manually triggered workflow or click DAG in the Actions column. In the DAG, you can right-click a manually triggered node to perform related operations.

Operation	Description
Run	In the DAG, right-click the desired manually triggered node and select Run. In the Run dialog box, configure the parameters and click Run. The Operating range parameter specifies the operation scope. Manually triggered node instances are generated for the manually triggered node. Range: The Specified Node option is automatically selected for Operating range. The current manually triggered node is automatically selected. You can add the descendant nodes that you want to run for the current manually triggered node. You can also set this parameter to The entire business process. Data Timestamp: Specifies the data timestamp range of the manually triggered nodes. You can click Add Multiple Data Timestamp Ranges to add multiple data timestamp ranges. You can select a date in the past or in the future to filter manually triggered nodes. Note If you click Add Multiple Data Timestamp Ranges to add multiple data timestamp ranges, the system runs manually triggered nodes based on the specified data timestamp ranges in chronological order. Workflow Parameters: If you configure workflow parameters for a manually triggered workflow that you develop, you must assign values to the workflow parameters when you run all manually triggered nodes in the workflow. For more information, see Use workflow parameters. Order: specifies whether to run manually triggered nodes based on the data timestamp range in chronological order or reverse chronological order. Note If you manage manually triggered nodes in a DAG, you can run a specific manually triggered node in the workflow. If scheduling dependencies are configured for the manually triggered nodes, you can specify the node from which a run starts.
View Code	Allows you to view the code of the manually triggered node.
Edit Node	Allows you to go to the DataStudio page to modify the manually triggered node.
View Lineage	Allows you to view the lineage of the manually triggered workflow.
Modify Scheduling Resource Group	Allows you to change the resource group that is used by the manually triggered workflow to run.
