[Start timer] event

The [Start timer] event enables you to run the process either once at a specified time, or regularly with a specified frequency.

You can select the frequency in the [Process launch frequency] field. The parameters of the [Start timer] event will differ depending on the selected option.

The base settings of the element are different depending on the frequency. Additional parameters are available for all frequency options (Fig. 1).

Fig. 1 [Start timer] element setup area with common parameters

scr_chapter_process_designer_start_timer_universal.png 

[Process start time] – the time at which the process will start.

[Timer validity] – the life cycle of the [Start timer] event, i.e., a time period during which the event is considered relevant and can be triggered. Populate these fields if you need to limit the period during which the [Start timer] event can be triggered for a process e.g., if you need the process to run every Friday for the next five weeks only).

[Repeat on misfire] – select this checkbox to ensure that the process launches even if the [Start timer] element cannot be triggered at the intended time, e.g., due to a server reboot.

[Time zone] – the time zone of the [Start timer] element. By default, the element time zone is set according to:

  • The time zone of the user who created a campaign.

  • The time zone specified in the [Default TimeZone] system setting (if no time zone has been set in the user profile).

If the time zone cannot be set according to the rules above, the [Time zone] field of a new campaign will have the “(GMT) UTC Time Format” default value.

Parameters of the “Once” frequency option

Select the "Once” frequency option in the [Process launch frequency] to run the business process only once at a specified time (Fig. 2).

Fig. 2 The [Start timer] event setup for one-time process launch

scr_chapter_process_designer_start_timer_once.png 

[Launch on] – the time at which the process will start.

Parameters of the “Minute/hour” frequency option

Select the "Minute/Hour” option in the [Process launch frequency] field to launch the process several times a day (e.g., working hours) (Fig. 3).

Fig. 3 The [Start timer] event setup for running the process every hour from 8 am till 8 pm

scr_chapter_process_designer_start_timer_m_h.png 

[Run every] – a process launch frequency in minutes or hours, as well as a time frame the process will be limited to. For example, you can run the process every hour from 8 am till 8 pm.

Parameters of the “Day” frequency option

If you select the "Day” option in the [Process launch frequency] field to launch the business process once a day at a certain time with specific intervals (e.g., every three days) (Fig. 4).

Fig. 4 The [Start timer] event setup for running the process every three days at 11 am

scr_chapter_process_designer_start_timer_day.png 

[Run every] – a launch frequency in days and a launch time. For example, you can run a process every three days at 11 am.

Parameters of the “Week” frequency option

Select the "Week” option in the [Process launch frequency] field to repeat the business process weekly on specified days at the specified time (Fig. 5).

scr_chapter_process_designer_start_timer_week.png 

[Launch on] – the time at which the process will be launched (e.g., 9:00 am).

[Which days of the week to run?] – select weekdays on which the process must start.

Parameters of the “Month” frequency option

Select the "Month” option in the [Process launch frequency] field to launch the business process monthly at certain days (Fig. 6).

Fig. 6 The [Start timer] event setup for running the process monthly

scr_chapter_process_designer_start_timer_month.png 

[Run every] – enter a time gap in months between each process launch. For example, you can automatically run the process every third month.

[Start day] – specify the launch day of the process. You can choose from the following options:

  • "Day of the month" is a specific day of month (e.g., every tenth of the month). For example, every tenth of the month.

  • "Day of the week" is the number and the day of the week of the month (e.g., every third Friday of the month).

  • "First / last work day" is the first or last business/regular day of the month.

Parameters of the “Year” frequency option

Select the "Year” option in the [Process launch frequency] field to run the business process every year on a certain date at the specified time (Fig. 7).

Fig. 7 The [Start timer] event setup for running the process every third Monday of October every year

scr_chapter_process_designer_start_timer_year.png 

[Start day] – select the day and the month when the process will start.  For example, 8th of March or every third Monday of October.

[Launch on] – the time at which the process will be launched (e.g., 9:00 am).

[Timer validity] – the life cycle of the [Start timer] event, i.e., a time period during which the event is considered relevant and can be triggered.

[Repeat on misfire] – select this checkbox to ensure that the process launches even if the [Start timer] element cannot be triggered at the intended time, e.g., due to a server reboot.

Parameters of the “Other frequency” option

Select the "Other frequency” option in the [Process launch frequency] field to set a custom process frequency via a cron-expression (Fig. 8).

Note

Cron is a planning utility widely used in UNIX-based operating systems. You can configure a more flexible launch date of a process using cron-expressions. We recommend consulting with your company’s system administrators before working with cron-expressions.

1.A cron-expression consists of numbers, words and symbols placed in a strictly defined order to specify the time, date, and year of the process launch. The following table shows a basic structure of cron-expressions:

Time units

Acceptable values

Special characters

Note

If the cron-expression is correct, you will see the time/date of the process launch in the traditional format in the [Cron-expression] field. If the expression is incorrect, bpm’online will display an error.

Examples of cron-expressions

0 * 14 * * ? – launches the process every minute from 14:00 to 14:59 daily.

0 0/5 14,18 * * ? – launches the process every 5 minutes from 14:00 to 14:59 and from 18:00 to 18:59 daily.

0 10,44 14 ? 3 WED – launches at 14:10 and 14:44 every Wednesday of March.

0 0 12 1/5 * ? – launches the process at 12:00 every 5 days, starting from the first day of the month on a monthly basis.
