Task Scheduler

Prerequisites

1.	Since you will be changing the times at which periodic tasks run, you should have a good understanding of what those tasks do. This is so that you don't run CPU intensive tasks too frequently or critical tasks too infrequently.

If you are not familiar with table windows, please read Working with table windows first.

The Task Scheduler window lets you edit the tasks that run periodically. The following is a description of the columns in this window:

Task ID	A unique number identifying the task. This field is not editable.
Description	A short description about what the task does. This field is not editable.
Module Name	The name of the module on behalf of which the task will be run. This field is not editable.
Minute	The minutes at which the task is scheduled to run. The following panel shows up when editing this field:
Hour	The hours at which the task is scheduled to run. The following panel shows up when editing this field:
Day	The days at which the task is scheduled to run. The following panel shows up when editing this field:
Month	The months at which the task is scheduled to run. The following panel shows up when editing this field:
Day of Week	The days of the week at which the task is scheduled to run. The following panel shows up when editing this field:
Last Run Time	The date and time at which the task last ran. This field is not editable.
Force Run Next Time	Force the task to run next time the cron job runs (with default settings, the cron job runs every 5 minutes) even if it is not scheduled to run. Valid values are yes and no. If it is set to yes, it will automatically be set to no the next time the task runs and completes successfully. Please note that disabled tasks cannot be forced to run using this field. The edit mode for this field is a dropdown list.
Status	The status of the task. Valid values are enabled and disabled. If it is set to disabled, the task will not run even if it is scheduled to run. Force Run Next Time will also not have any effect if this field is set to disabled. The edit mode for this field is a dropdown list.

Selecting the times at which a task must run

If you would like to run a task every 15 minutes, you would select :00, :15, :30 and :45 in the minutes column as well as everything in the hour, day, month and day of week columns. If you select the above options in the minutes column, select 09: in the hour column and everything else in the day, month and day of week columns, the task will run every 15 minutes only during the 9th hour of every day. A few examples follow ([all] indicates select all available options in that column):
