Modifying Tasks in an Active Schedule

The Schedule Monitor provides detailed information on the progress of the Schedule and of the executions of its sub tasks. It is available as soon as a Schedule has started and allows you to modify some parameters in the Schedule object definition. It also allow you to modify some of the properties of its tasks as long as it is still active. Changes to task properties affect only the current execution of the Schedule.

Changes done to the Schedule and its tasks are recorded in the Reports.

Effects of Modifying Task Properties during Execution

This list explains the effects of changes during execution:

• Set start time forward

  For tasks that are waiting for their start time.

  Result: The task starts at the new start time

• Set start time backward

  For tasks that are waiting for start time.

  Result: The task starts at the new start time. If the new start time lies ahead of the current time, the task obtains the "ENDED_TIMEOUT - Start time exceeded" status.

• Reset start time backward or forward

  For tasks that are already finished (any end status).

  Result: The task will only start at the new time after the period turnaround .

• Set active

  For tasks that are waiting for start time.

  Result: The task starts at the defined start time.

• Set inactive

  For tasks that are waiting for start time.

  The task obtains the "ENDED_INACTIVE" status at the start time and is not executed.

• Settings for runtime supervision

  • Task waits for start time

    For tasks that are waiting for start time.

    Result: The task starts with the new setting for runtime supervision.

  • Task is already finished (any end status)

    For tasks that are already finished.

    The task will only start with the new setting for runtime supervision .

To Modify the Editable Properties of a Task in an Active Schedule

1. Click the Modify button on the Monitor toolbar to activate the edit mode.
2. Select the task you want to modify.

3. You can modify the following settings directly from the list of tasks in the Schedule:

   • Active

     This checkbox is activated by default. This means that this task will be executed according to the settings you are about to define.

     If you deactivate it, the task remains as part of the schedule object but will not be executed with it. It obtains the ENDED_INACTIVE status.

   • Start Time

     The time at which this task will be executed. The default value is the time defined in the Period Turnaround Time field on the schedule's Attributes page.

     You can specify here a different start time for every task in the schedule but take into account that the task start time must always be after the period turnaround time.

   • Start Offset (days)

     You use this field in combination with the period duration and turnaround time. Enter here the number of days that should elapse between the beginning of a period and the activation of the selected task.

4. To modify other parameters, click the Properties button on the toolbar. This opens a pane at the bottom half of the window. It is divided in several tabs containing the task settings. You can only change the properties in the Runtime tab, the rest serve for information purposes only.

   On the Runtime Page of the Schedule object definition, you define the parameters to calculate the maximum and minimum runtimes of tasks. This pane allows you to override these definitions for this task's executions within the schedule object.

   When monitoring the task runtime, you can react quickly to runtimes that exceed the maximum defined by canceling or ending the task or executing another one. Likewise, when the execution has ended, you can check whether it was processed in at least the minimum runtime defined and, if not, you can react accordingly.

5. Click Save.
