Document Properties: Scheduling

The Scheduling properties page allows you to set up conversion schedules.

Introduction

A given document entry can have zero, one, or multiple schedules for conversion. If an entry has one or more schedules for conversion then when a scheduled conversion is called upon for the conversion list file containing it, then its schedules are checked to see whether it is scheduled for conversion at that time. A schedule can be set to cause a conversion to happen once, hourly, daily, weekly, monthly, or always whenever a scheduled conversion occurs.

An example of where multiple schedules can come in handy is in the case of a news site that has daily, weekly, and monthly summaries of the corresponding period's most popular news articles. The daily schedule might be set to occur every day at 8PM, the weekly schedule might be set to occur every week on Saturday at 9AM, and the monthly schedule might be set to occur every month on the last day of the month at 10PM.

Scheduled Conversions

When you have a conversion list open in iSiloX and an entry is scheduled for conversion, you will be prompted for whether you want the scheduled conversion to occur. If you do not answer the prompt within 30 seconds, the scheduled conversion occurs automatically. The prompt also gives you the option of delaying the scheduled conversion until some number of minutes later.

If you use iSiloX to save a conversion list that has one or more entries with conversion schedules, when you exit iSiloX or close that conversion list, iSiloX automatically sets up a scheduled task using the Windows Task Scheduler to call iSiloX to perform a scheduled conversion for the earliest next scheduled conversion time among the entries in the list. So even if you do not have the document list open in iSiloX, scheduled conversions can still occur.

Note that your computer must be on at the time of the scheduled conversion for the scheduled conversion to occur.

Windows XP and Windows 2000 require an account to have a password if it is to run a scheduled task. So if your account does not have a password, you must create a password for it. See your Windows documentation for information about creating a password for your account.

On Windows XP and Windows 2000, if you want scheduled conversions to occur even if you are logged out, you need to exit out of the Properties dialog. Then go to the Document menu and click "Scheduled Conversion Account". Uncheck the option "Run scheduled conversions only if logged on". On Windows NT, you must be logged in for scheduled conversions to occur. On Windows 95, Windows 98, and Windows Me, scheduled conversions occur regardless of whether you are logged in or not.

Schedule List

The Scheduling property page shows the schedules for the document entry in a two-column list, one schedule per row. For a given schedule, the first column, labeled Schedule, displays a summary of the schedule and the second column, labeled Disable, shows whether the schedule is disabled or not. You can quickly disable or enable a schedule by clicking in its Disable column. To disable all schedules, check Disable scheduled conversions.

The Last scheduled conversion field shows the most recent scheduled conversion that occurred. It is for informational purposes only. To remove the information, uncheck the checkbox.

The Next scheduled conversion field shows when the next scheduled conversion is to occur. It is the earliest next conversion time among the enabled schedules in the list.

Adding a New Schedule

Click Add new schedule to add a new schedule. Doing so displays the Add New Schedule dialog. A schedule can be one of the six types listed as selections in the Frequency box. Select the type of schedule you want to add, then fill in the relevant details. The following subsections describe the schedule types and the options available.

A Once schedule is a scheduled conversion that occurs only once at a date and time that you specify. To set up a Once schedule do the following:
  1. In the Frequency box, select Once.
  2. To the right of the Once option, specify the date and time of the conversion.

Hourly

An Hourly scheduled conversion occurs at a specified number of minutes after the hour either once every specified number of hours or at chosen hours of the day. An hourly schedule can also have an effective start and/or end date and time. To set up an Hourly schedule, do the following:

Monthly

A Monthly scheduled conversion occurs at a specified time of the day on a given day of the month either once every specified number of months or on chosen months of the year. A monthly schedule can also have an effective start and/or end date and time. To set up a Monthly schedule, do the following:
  1. In the Frequency box, select Monthly.
  2. To the right of the Monthly option, specify the time of day and day of the month on which to perform the conversion.

Always

An Always schedule says that a conversion should happen whenver the scheduled conversion of any other entry occurs. To set up an Always schedule, do the following:
  1. In the Frequency box, select Always.

  3. To have the schedule no longer active after a given date and time, in the Options box, check End date and specify the end date and time.

Last and next scheduled conversions

The bottom of the Add New Schedule dialog shows the date and time of the last scheduled conversion for the schedule as well as the next computed scheduled conversion time according to the current Frequency and Options choices you have made. iSiloX uses the last scheduled conversion time along with the schedule settings you have chosen to determine the next scheduled conversion date and time. When you add a new schedule, there is no last conversion time, so iSiloX computes the next scheduled conversion time as some future time after the current time. You can modify this behavior by checking Last and specifying the last scheduled conversion time, but it is unlikely you will need or want to do so since you can always specify a starting date and time for the schedule by checking Start date in the Options box and specifying the date and time when the schedule first takes effect.

Disabling the schedule

If you want to disable a schedule but keep its settings around for a future time when you may want to enable it again, you can check Disable. Uncheck it at some future time to enable it again. You can also easily enable and disable a schedule from the schedule list for the document entry.

Editing an Existing Schedule

Double-click a schedule in the schedule list to get the Edit Schedule dialog to edit the schedule's settings. The Edit Schedule dialog is identical to the Add Schedule dialog. See Adding a New Schedule above for information about the dialog.

Deleting Schedules

Select one or more schedules in the schedule list then click Delete selected schedules to delete the selected schedules. iSiloX asks for confirmation before deleting the schedules.
