Add a new task

• Select an input broker that was defined earlier through Brokers.

• Click "Submit" button to add the new task.

• Select the directory and file to be imported.
• Click on "Open" to import the file, it will be imported as a task on the task list.

For individual tasks

Following are the actions that can be performed on individual harvesting tasks:

Run

• Click the "run" link for an individual task on the "Tasks" page to run the task immediately, you can check the progress and status of the job by clicking on the "Home" page, you can also cancel a task by clicking on "cancel" link for the task.

Schedule

• Click the "schedule" link for an individual task on the "Tasks" page to schedule the task to run at a future date/time.
• There are two options:
  • Harvest at: to harvest at a particular time, if you would like the task to start at an exact time each day, choose this option.
  • Harvest periodically: to harvest at certain frequency, the task will restart at the interval specified (counted from previous task completion time).

Export
