One-time tasks are submitted to the Operation Center with the schedule type set to manual. These tasks do not run automatically. Instances are generated only when you manually trigger the tasks. This topic describes the Operations and Maintenance (O&M) features for one-time tasks.
Go to the one-time task page
In the top menu bar of the Dataphin home page, choose Develop > O&M.
In the navigation pane on the left, choose O&M > One-Time Task to go to the One-Time Task page.
In the top menu bar, select the production or development environment.
One-time task page overview
The one-time task page includes a filter and search area, a list operations area, a one-time task list, and a batch operations area. On this page, you can perform O&M operations on submitted one-time tasks.

Section | Description |
① Filter and search area | Filter one-time tasks by task object name or ID. This is useful for quickly finding a specific task. You can also select My Tasks or Updated Today to filter tasks.
|
② List operations |
|
③ One-time task list | The one-time task page lists the one-time tasks that are submitted to the Operation Center. The list shows the Task Object, Priority, Operation Owner, Project, HTTP path, Resource Group, Last Update Time, Tag, and supported Actions.
|
④ Batch operations area | Use the batch operations area to perform O&M on multiple one-time tasks at a time. This improves efficiency. For more information, see Batch operations for one-time tasks. |
Supported operations for the one-time task list
Operation | Description |
View Node Code | Go to the code details page to view the node code of the one-time task. |
View Instances | View the one-time instances generated when the task runs. You can also perform O&M on the one-time instances. |
Run | Manually trigger the task to run. For more information, see Run a one-time task. |
Edit Development Node | Go to the task's edit page in the Dev project to edit the task. This applies only to the Dev-Prod development model. Note After you edit the development node, you must submit or publish it to update the data on the production node. |
Edit Node | Edit the node of a task. This applies only to the Basic model. Note After you edit the node, you must submit or publish it to update the data on the production node. |
View Node Script | View the dependency graph of the pipeline task. Note Only one-time tasks submitted from the Data Integration module support viewing node scripts. |
View Production Node | Go to the Prod project to view the task node data. |
Modify Operation Owner | Modify the O&M owner of the task. Note
|
Configure Monitoring and Alerting | Configure monitoring rules for task runs. If a monitoring rule is triggered during a task run, the system sends you an alert message. This helps you promptly detect exceptions and ensure normal data output. For more information, see Overview of offline task monitoring. Note The system supports monitoring configuration only for tasks in Prod and Basic projects, which are production environment tasks. |
Modify HTTP path | Modify the production environment HTTP path for the task. You can select from all HTTP paths that are configured for the corresponding cluster in the production project. Note This operation is supported only when you select Databricks SQL tasks in the production environment. |
Modify Schedule Resource Group | Modify the schedule resource group that the task instance uses at runtime. Note
|
View node code details
In the Actions column, click the
icon or click the task object name to display the task details on the right side of the page. You can click the
icon to hide the one-time task list on the left and expand the details view.

Section | Description |
① O&M management area | Provides entry points for O&M of one-time tasks.
|
② Node information area | Displays the node and run information of the one-time task. |
③ Task code area |

Run a one-time task
Click Run to open the Run dialog box.
In the Run dialog box, configure the following parameters.
Parameter
Description
Data Timestamp
You can select By Range, By Period, or Custom. By Range is selected by default. The default range is
current data timestamp to current data timestamp.By Range: After you select By Range, select a time range. The time range cannot exceed 1 year. This is suitable for scenarios where the current task needs to run continuously for multiple data timestamps.
By Period: After you select By Period, select a time range and specify the days of each week or month. The time range cannot exceed 1 year. The default is
current data timestamp to current data timestamp. This is suitable for scenarios where the current task needs to run on specific days of the week or month within multiple consecutive data timestamps.Weekly: The task runs on the selected days of each week, such as Monday and Tuesday.
Monthly: The task runs on the selected dates of each month, such as the 1st, 5th, and 10th.
NoteEnd of month refers to the last day of each month.
Custom: Enter multiple data timestamps in the
YYYY-MM-DDformat. Separate multiple data timestamps with line breaks. You can enter data timestamps in the range of1900-01-01 to present. Dates outside this range are invalid.
Concurrent Runs
The default value is 1. You can enter an integer from 1 to 12.
Run Order
Select Data Timestamp Ascending or Data Timestamp Descending. The default is Data Timestamp Ascending, which means tasks are run one by one in ascending order of data timestamp.
Parameter Settings
If the one-time task includes local variables, the task runs with the configured parameter values after the local parameters are configured. You can select Fill Empty Values. The parameter values remain the same for all instances generated by the task.
After you finish the configuration, click Submit.
Batch operations for one-time tasks
Operation | Description |
Run | Select multiple tasks and click Run at the bottom of the list. Configure the data timestamp, number of concurrent runs, and run order for the batch run. For more information about the parameters, see Run a one-time task. Note
|
Modify Operation Owner | Select multiple tasks and click Modify Operation Owner at the bottom of the list to modify the O&M owner for multiple tasks at the same time. Note
|
Modify Priority | Select multiple tasks and click Modify Priority at the bottom of the list to modify the priority for multiple tasks at the same time. At a given time, among all tasks that meet the scheduling conditions, tasks with a higher priority run first. After you modify the task priority, the new priority is used for the next scheduling. The priority modification takes effect immediately. You do not need to submit or publish the task. Note This applies only to Prod and Basic projects, which are production environment tasks. |
Modify HTTP path | Modify the production environment HTTP path for multiple Databricks SQL tasks. If the selected Databricks SQL tasks belong to different Databricks clusters, specify the HTTP path for each cluster. You can select from all HTTP paths that are configured for the corresponding cluster. Note This operation is supported only when you select Databricks SQL tasks in the production environment. |
Modify Schedule Resource Group | Select multiple tasks and click Modify Schedule Resource Group at the bottom of the list to modify in batches the schedule resource group that the instances generated by the tasks use at runtime. Note
|
