The Once option in the Run Interval drop-down list sets the job to execute immediately. You can modify the date or time if you do not want the schedule to run immediately. You can specify the date and time you want the schedule to run using the Start Schedule options, as shown in the following image.

To select a date, choose a date from the drop-down date calendar. To select a time, select either the hour or minutes and use the up and down arrows to increase or decrease the value.

The Minute(s) option in the Run Interval drop-down list, sets the schedule to run every n minutes.

In the Every minute(s) field, type or select the minutes interval (1 to 59), check the days of the week on which you want to run the schedule, and select the Start Schedule and End Schedule date and time to define the time period in which the schedule will run. For example, the following schedule will run every 30 minutes on Mondays and Fridays beginning at noon May 16, 2008 and ending 6:00 PM October 30, 2010.

Tip: Selecting this option may affect system performance if you choose to run the schedule every 5 minutes or less. We recommend specifying a minimum of 30 minutes. The minute interval option is primarily useful for alert schedules.

The Hour(s) option in the Run Interval drop-down list, sets the schedule to run every n hours.

In the Every hour(s) field, type or select the hours interval (1 to 24), check the days of the week on which you want to run the schedule, and select the Start Schedule and End Schedule date and time to define the time period in which the schedule will run. For example, the schedule shown in the following image will run every 3 hours on Mondays and Fridays beginning at noon May 16, 2008 and ending 6:00 PM October 30, 2010.

The Day(s) option in the Run Interval drop-down list, sets the schedule to run every n days. In the Every day(s) field, type or select the days interval to run the schedule and select the Start Schedule and End Schedule date and time to define the time period in which the schedule will run. For example, the schedule shown in the following image will run every 5 days beginning at noon May 16, 2008 and ending 6:00 PM October 30, 2010.

The Week(s) option in the Run Interval drop-down list, sets the schedule to run every n weeks.

In the Every week(s) field, type or select the weekly interval to run the schedule, check the days of the week on which you want to run the schedule, and select the Start Schedule and End Schedule date and time to define the time period in which the schedule will run. The following schedule will run every two weeks on both Monday and Friday beginning at noon May 16, 2008 and ending 6:00 PM October 30, 2010.

Important: When selecting the Week(s) interval, set the Start Schedule to the date of the first day (current or future) of the week you want the schedule to run. If you select the current date, then you must make sure that the Start Schedule time is later than the current time when you save the schedule. If the Start Schedule time is less than or equal to the current time, the calculation for the next run time results in the schedule not running on the current date.

The Month(s) option in the Run Interval drop-down list, sets the schedule to run every n months. You can then refine the monthly interval with one of the following options. Note that these options are mutually exclusive.

• Every first, second, third, fourth, or last n day of the week (where n is Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, or Sunday) every n months.
• Specific days every n months.

Also select the Start Schedule and End Schedule date and time to define the time period in which the schedule will run. The following image shows a schedule set to run on the first Monday of every month beginning at noon May 16, 2008 and ending 6:00 PM October 30, 2010.

The following image shows a schedule set to run on the 2nd, 9th, 16th, 23rd, and 30th of every month, regardless of the day of the week those dates fall on.

You can also select the Last Day of the Month option at the end of the calendar to run the schedule on the last day of the month.

Note: When selecting the Month(s) interval, set the Start Schedule to the date of the first day (current or future) of the month you want the schedule to run. If you select the current date, then you must make sure that the Start Schedule time is later than the current time when you save the schedule. If the Start Schedule time is less than or equal to the current time, the calculation for the next run time results in the schedule not running on the current date.

The Year(s) option in the Run Interval drop-down list, sets the schedule to run every n years during a specific time period. The following image shows a schedule set to run every 2 years beginning at noon May 16, 2008 and ending 6:00 PM October 30, 2010.

The Apply secondary run interval option allows you to create a secondary run interval within the day the schedule runs. You can apply the secondary run interval every n minutes or hours for a specified number of hours and minutes or until a specified time. This option is available for schedules that run every day(s), week(s), month(s), or year(s).

The secondary run interval will not be validated when the schedule is created. Instead, validation is performed every time the schedule's next run time is calculated when running within the secondary run interval. The secondary run interval cannot exceed the next run time for the primary run interval. For example, a daily schedule cannot have a secondary run interval greater than Every 1 day(s). If a secondary run interval is scheduled to run after the schedule's next primary run interval, the secondary run interval is stopped and an error message appears. This error message is also written to the log file.

When you select Apply a secondary run interval, the options related to this setting appear in the Frequency section. The following image shows an example of set secondary run interval options.

The Apply secondary run interval options are:

• Every n [minutes|hours]. Applies the secondary run interval every n minutes or hours (in this example every 10 minutes) within the day the schedule runs.
• Until Time. The time up until which the secondary run interval will be applied. In this example, the schedule will be rerun every 10 minutes until 4:00 P.M.
• Lasts for n hour(s) n minute(s). The duration, specified in hours and minutes, during which the secondary run interval will be applied. This option and the Until time option are mutually exclusive, so, in this example, this option is inactive.
