Advanced scheduling options

In a database, file or web service connection point, a schedule can be defined for reading data. The user can specify a number of minutes, hours, days or weeks. You can specify more details in an advanced schedule using a CRON expression. For example, to run an expression on 8 pm every day, or to run every week on Monday, Wednesday and Friday at 5 am.

The Quartz CRON scheduler is used, where the expression is of this format:

[Seconds] [Minutes] [Hours] [Day of the Month] [Month] [Day of the week] [Year]

For example, for triggering:

• The scheduler at 9:30 AM every day, you can use the expression: 0 30 9 ? * *
• The scheduler every 5 minutes, you can use the expression: 0 0/5 * * * ?.

To learn more about the cron fields and sample expressions, see the documentation of quartz scheduler at:

Note that support for specifying both a day-of-week and a day-of-month value is not provided. If you must specify both, use the '?' character in one of the fields.
