The Jobs tab contains two panes: Schedules and Executables. The Schedules pane shows the various system jobs that are available. The Executables pane shows what program or programs will execute when the system job selected in the Schedules pane runs. These panes are described in more detail in the following sections.

The Schedules Pane

The Schedules pane shows all system jobs. These jobs may be run on demand or scheduled to automatically execute periodically.

This tab contains the following columns:

• Comments: This column contains a description of what the job does.
• Commit Between Executables: When this check box is selected, the system will commit all transactions resulting from one executable before starting the next executable.
• CRON Expression: This column shows an abbreviated description of when the job is scheduled to run. The value in this column is created or modified by using the Set Schedule right-click command.
• End Time: This column sets the end of the time period in which the system will process the CRON expression. You may enter a date directly or click the calendar icon to display a calendar. Once the day specified in this field is reached, the job will no longer run.
• Job Name: This column shows the name of the system job.
• Scheduled?: If the check box in this column is selected, then the schedule set for this job (by using the Set Schedule right-click command) will be followed and the job will run automatically according to that schedule provided a user called SYSTEM is in the User Names and Access window.
• Start Time: This column sets the beginning of the time period in which the system will process the CRON expression. You may enter a date directly or click the calendar icon to display a calendar.

When you right-click a particular system job in the list, in addition to the common commands the following special commands are available:

• Delete Schedule: This command deletes the selected schedule record from the pane.
• Insert Schedule: This command inserts a new schedule record in the pane.
• Next Fire Date: For scheduled jobs, this command will display when the selected job will next run.

• Run Job: This command initiates the system job that you right-clicked.

  Note: If you right-click the Run Interface system job, the system displays a dialog box with the list of available interfaces in a drop-down list. Click the down arrow to display the list of interfaces, click the desired interface to be run, and finally click OK.

• Set Schedule: This command allows you to set the periodic schedule by which the selected job will be automatically run. After selecting the command, the system displays the CRON Expression Editor dialog box.

The Executables Pane

For the system job selected in the Schedules pane, the Executables pane shows one or more programs that will execute when the system job runs. (When multiple programs are listed, they execute in the order set by the Order column, with the next program starting when the previous job finishes. If any program in the series fails, then the entire job halts and all changes are rolled back.)

The programs shown in the drop-down list in the System Job Executable column are those listed in the System Job Executables window.

The input values for a program are set by right-clicking the record for the program and then clicking Define Argument(s). The system responds by displaying a dialog box so you may enter the input values. Once you enter these values and close the dialog box, the values will appear in the Arguments column.
