Cancel Remaining Tasks (Topographic Production)

摘要

Prevents the remaining tasks in a job from starting or being created. The active task and its task group job will still complete.

使用情况

• A task group, or parent job, is composed of a series of tasks, or child jobs.

• This tool can be run while a task or task group is running if there is no longer a need to complete the remaining tasks.

• This tool is intended for use with the topographic mapping production management workflows and requires a properly configured ArcGIS Workflow Manager (Classic) repository.

• The TOPO_TASK_PROPERTIES table is used to determine which tasks remain for a job, and the table is updated to indicate that the remaining tasks no longer need to be run.

• Use the ID of the parent task group as the Job ID parameter value, not the child task job.

CancelRemainingTasks example (stand-alone script)

The following stand-alone script demonstrates how to use the CancelRemainingTasks function in Python.

# Name: CancelRemainingTasks_sample.py
# Description: This script attempts to run a child job. If there is an exception
# and the child job fails to run a step, the Cancel Remaining Tasks tool is
# called to cancel the remaining tasks for parent job.

# Import System Modules
import arcpy

# Check Out Extensions
arcpy.CheckOutExtension('Foundation')
arcpy.CheckOutExtension('JTX')


# Setting Local Variables
job_id = 15
workflow_database = r'C:\Data\Workflows\Testing.jtc'

#Connect to the workflow database
connection = arcpy.wmx.Connect(workflow_database)

#Get a Job for Execution
job = connection.getJob(job_id)

# Execute the job
try:

	result = job.executeStep()

#Raised when a step in the workflow encounters an execution error
except wmx.WorkflowExecutionStepError as e:
    print ("Step failed to execute, canceling remaining tasks.")

    # get the id of the parent job
    parent_id = job.parent

    # If an exeception happens, call the Cancel Remaining Tasks tool to cancel
    # all the remaining tasks for the parent job.
    arcpy.topographic.CancelRemainingTasks(parent_id, workflow_database)


# Check In Extensions
arcpy.CheckInExtension('Foundation')
arcpy.CheckInExtension('JTX')
