This page is for data modellers, application designers and system administrators. It explains how to create a task plan, which will run one or more tasks.

Overview

When working with data, applications and IT systems, there are routine processes that you need to run. PhixFlow makes it easy for you to set up and manage these processes using task plans, to which you add tasks.

Running Task Plans

Excerpt
You can run a task plan:
  • manually, using the property tab toolbar button 
    Insert excerpt
    _taskplan_start
    _taskplan_start
    nopaneltrue
    .
  • automatically at a scheduled date and time, using the Scheduled check box and related Schedule section.
  • by linking it to an application action, in the action properties → Run Task Plan section; see Table-Action.
    When the user clicks something in the application, such as a button or a data row, the task plan runs.

When a task plan runs, its tasks are run in the order they are listed.

You can optionally set up a list of users who will receive an email about the outcome of running the task plan.

Task Plan Properties

The property tab toolbar includes the

 button. Click this to manually run the task plan.

Basic Settings

FieldDescription
NameThe name of the task plan.
Enabled

Insert excerpt
_check_box_tick
_check_box_tick
nopaneltrue
 to indicate the task plan configuration is complete and it can be run.

Insert excerpt
_check_box_untick
_check_box_untick
nopaneltrue
 to prevent the task plan being run. For example, during maintenance, you may not want the task plan to run at the scheduled time.

Scheduled

Insert excerpt
_check_box_tick
_check_box_tick
nopaneltrue
 to add a Schedule section to the properties, where you can configure the day and time that the task plan will run. 

Insert excerpt
_check_box_untick
_check_box_untick
nopaneltrue
 for task plans that you want to run manually. 

Suspend on Failure

Insert excerpt
_check_box_tick
_check_box_tick
nopaneltrue
 to set PhixFlow to automatically tick the Suspended checkbox if running the task plan generates an error message. You can find the error messages in the log file; see Server Log Files.

Insert excerpt
_check_box_untick
_check_box_untick
nopaneltrue
 so that a task plan can report errors without preventing the next run.

Suspended

Insert excerpt
_check_box_tick
_check_box_tick
nopaneltrue
 prevents the next run of the task plan. PhixFlow automatically ticks this box if the task plan generated an error message on its previous run. This means the task plan will not run again until you have:

  • resolved the problem that caused the error message
  • and unticked the Suspend checkbox.

Insert excerpt
_check_box_untick
_check_box_untick
nopaneltrue
 indicates the task plan can run as no errors were reported in the previous run.

Protect on import

Insert excerpt
_check_box_untick
_check_box_untick
nopaneltrue
 to allow this task plan to be updated or deleted by import from another PhixFlow instance.

Insert excerpt
_check_box_tick
_check_box_tick
nopaneltrue
 to retain the Enabled, Scheduled, Suspend on Failure, Suspended and Schedule settings if this task plan is imported from another PhixFlow instance.

    Note: You cannot use a wild card in the Seconds field.

    FieldDescription
    Exclusion Group

    This field is case insensitive. If this field is not empty, only one task plan with this Exclusion Group can be running at any one time. Attempting to run a second task plan with the same exclusion group will return a warning and the task plan will not run. This applies whether the task plan is run manually, automatically using a schedule, or by an action.

    When running an action, the initial phase will evaluate the task plan rules and determine which task plan (if any) to run. If the task plan to run has an exclusion group and there is already a task running with this exclusion group then the action will not continue and returns a warning. Exclusion Group are evaluated before any tasks or actions are started. 

    If there is no task already running with this exclusion group then the action will continue. The action will be considered to be using this exclusion group from this point until the task plan has completed.
