Managing Triggers

Creating a Time Trigger


  1. In a folder, navigate to Automations > Triggers and on the Triggers page, click Add a new trigger. The Create Trigger page is displayed.
  2. Select Time as the trigger type.
  3. In the Name field, add a name for the trigger to easily identify it.
  4. From the Process Name drop-down menu, select the process you want to configure a time trigger for.
  5. From the Job Priority drop-down menu, select the priority of the job. The default value is Inherited, meaning that the job priority is the same as the one defined for the selected process.
  6. From the Runtime type drop-down menu, select the runtime used to execute the jobs that are launched by the trigger.
  7. On the Execution Target tab, select your jobs' allocation mechanism and execution target.
Desciption
Dynamic allocationAllocate Dynamically

Dynamic allocation with no explicit account and machine selection allows you to execute a foreground process multiple times under the account and machine that become available first. Background processes get executed on any account, regardless if it's busy or not, as long as you have sufficient runtimes.

Using the Allocate Dynamically option you can execute a process up to 10000 times in one job.
Account

The process is executed under a specific account. Specifying only the account results in Orchestrator allocating the machine dynamically. Specifying both the account and the machine template means the job launches on that very account-machine pair.
Machine

The process is executed on one of the host machines attached to the selected machine template. Specifying only the machine template results in Orchestrator allocating the account dynamically. Specifying both the account and the machine template means the job launches on that very account-machine pair.

Make sure the required runtime licenses to execute the job are allocated to the associated machine template.
Hostname

After selecting a machine template, the Hostname option is displayed, allowing you to select the desired workstation/robot session to execute the process.

All available sessions in the active folder are displayed, either unconnected, disconnected, or connected.

Note:
Only unattended runtimes can be used to configure the mapping. Make sure the required runtime licenses to execute the job are allocated to the associated machine template.
Select valid account-machine mappingsThe process can be executed on specific account-machine pairs. Learn more about account-machine mappings.

Notes:
● A warning is displayed upon selecting a hostname that is not active (i.e., with the Unresponsive or Disconnected status).
● Accounts part of mappings that are employed in triggers cannot be deleted or unassigned from the folder the trigger resides in. Make sure the account is not set as an execution target in a trigger so you can delete them.

📘

Hostname selection

  • A warning is displayed upon selecting a hostname that is not active (i.e, with the Unresponsive or Disconnected status). Jobs scheduled to be executed by the inactive session remain in a Pending state until the corresponding connection to Orchestrator is made.
    To acknowledge your selection of the inactive hostname, click Confirm.
    To go back and select another hostname, click Cancel.

  • Configuring the same trigger with the same account-machine mapping, but with an additional hostname selection doubles the number of jobs to be executed.
    For example, say you configured a trigger T1 with the account A1 mapped to the machine template MT1. A number of ten jobs are queued for execution in this configuration.
    Later on, you configure the same trigger T1 with the account A1 mapped to the machine template MT1, but now you also select a hostname H1. The same ten jobs are queued again for this case, as Orchestrator interprets the configuration as new.
  1. On the Arguments tab, provide values for input arguments if your process has any. More details about input and output arguments.
  2. From the Timezone drop-down menu, select the time zone according to which the trigger is to be set off.

📘

Note

  • The trigger time zone is not dependent on the tenant time zone. You can set a different time zone for your time trigger execution.

  • Locations that use daylight saving time (DST) are listed in their UTC offset. The UTC offset is not increased when DST is in effect. For example, during the DST period, the London time zone is displayed as UTC+00:00.

  • You do not have to adjust the time zone in order to account for DST, as Orchestrator's schedule mechanism automatically takes into account when launching a job. A job scheduled to run at 12:00 runs at 12:00 both in winter and summer.

  1. Select the execution frequency of the trigger (Minutes, Hourly, Daily, Weekly, Monthly, Advanced). On the right side of this section, configure the details depending on the chosen option (frequency, exact time, or a cron expression). Orchestrator uses an open-source library to parse and display cron descriptions, which can be found here.

  2. From the Non-working days restrictions drop-down menu, select a non-working days calendar, if you want your trigger to stop firing on certain non-business days. More details about non-working days.

  3. Turn on the Schedule ending of job execution toggle to select a job termination strategy.

📘

Note

  • The amount of time specified here elapses according to the specifications, even if the job is queued. For example, if you schedule a job to run at 1 p.m. and set it to stop after 20 minutes, the job stops at 1:20 p.m. even if it had stayed in a queue until 1:15 p.m., and then started.

  • The Schedule ending of job execution options of a trigger are preserved for manually started jobs.
    Say you created the trigger T1 and you activated the following job ending schedules:

    • Schedule ending of job execution: Stop a job after 10 mins
    • Schedule automatic "Kill", if the job does not stop: Kill job after 2 mins
      On the Automations > Triggers page, when you click Start a Job Now for the trigger T1, the Start Job page opens with the job ending schedules already applied, the same ones you configured when you created the trigger.
  • Select Stop from the drop-down—attempts to gracefully end the execution of jobs in either Running or Pending states after the defined time interval has passed since the job creation (set the time to a minimum of 1 minute, maximum of 10 days, 23 hours and 59 minutes). The job transitions to a Stopping status.
    Example: Orchestrator attempts to stop jobs 10 minutes after the job creation time.
533533
  • Select Kill from the drop-down - attempts to forcefully end the execution of jobs in Running and Pending states after the defined time interval has passed since the job creation (set the time to a minimum of 1 minute, maximum of 10 days, 23 hours and 59 minutes);
    Example: Orchestrator attempts to kill jobs 10 minutes after the job creation time.
522522
  • Select Stop from the drop-down and enable the Schedule automatic "Kill", if the job does not stop option - attempts to gracefully end the execution of jobs in Running or Pending states after the defined time interval has passed since the job creation, and then attempts to forcefully end it after the defined time interval has passed since the job is stuck in a Stopping state (set the time to a minimum of 1 minute, maximum of 10 days, 23 hours and 59 minutes).
    Example: Orchestrator attempts to stop jobs 10 minutes after the job creation time. If the termination does not happen, Orchestrator attempts killing those jobs that have been Stopping for at least 20 minutes.

  1. Turn on the Schedule automatic trigger disabling toggle, and enter the date and time when the trigger is to be disabled. The time zone selected in step 9 influences when the time trigger gets disabled.
  2. Turn on the Generate an alert if the job is stuck in pending or resumed status toggle, and set the acceptable duration for the job to remain in the pending or resumed status. The configurable duration is minimum one minute and maximum eleven days. If the job exceeds the configured duration, an "Error" severity alert pop-up informs you about it with the following text:
    "N jobs for #process {process_number} have been pending or resumed for more than X hours and Y minutes.", where:
  • N - is the number of jobs that triggered the alert;
  • {process_number} - the process identifier;
  • X - the configured number of hours the job exceeded while having the pending or resumed status;
    Note: Days are converted to hours.
  • Y - the configured number of minutes the job exceeded while having the pending or resumed status.
  1. Turn on the Generate an alert if the job started and has not completed toggle, and set the acceptable duration for the job to complete. The configurable duration is minimum one minute and maximum eleven days. If the job exceeds the configured duration, an "Error" severity alert pop-up informs you about it with the following text:
    "Job for #process {process_number} has been pending been running for more than X hours and Y minutes.", where:
  • {process_number} - the process identifier;
  • X - the configured number of hours the job exceeded while trying to complete;
    Note: Days are converted to hours.
  • Y - the configured number of minutes the job exceeded while trying to complete.
  1. To keep the same account-machine context configured for starting the job (step 7), check the Keep Account/Machine allocation on job resumption box. This optimizes your license and resource usage. Read more about this option (the table in step 6).

Creating a Queue Trigger


Note: Queue triggers and SLA predictions are interdependent in terms of queue-process association. So whenever configuring one, the other is prefilled such as to have parity between the configurations. Say I define a queue trigger for queue Y to use process X. SLA predictions for queue Y can only be made using process X, therefore X is prefilled and read-only when enabling queue SLA for Y.

🚧

Connected queue triggers

For processes containing queue trigger activities, you need to create and edit the corresponding queue triggers only from the Package requirements page, at process creation time. Manually created triggers (that is, from the Triggers page) won't be recognized by the queue trigger activity in the workflow.

  1. In a folder, navigate to Automations > Triggers and on the Triggers page, click Add a new trigger. The Create Trigger page is displayed.
  2. Select Queue as the trigger type.
  3. In the Name field, add a name for the trigger to easily identify it.
  4. From the Process Name drop-down menu, select the process you want to configure a time trigger for.
  5. From the Job Priority drop-down menu, select the priority of the job. The default value is Inherited, meaning that the job priority is the same as the one defined for the selected process.
  6. From the Runtime type drop-down menu, select the runtime license type.
  7. On the Execution Target tab, select your jobs' allocation mechanism and execution target.
Desciption
AccountThe process is executed under a specific account. Specifying only the account results in Orchestrator allocating the machine dynamically. Specifying both the account and the machine template means the job launches on that very account-machine pair.
MachineThe process is executed on one of the host machines attached to the selected machine template. Specifying only the machine template results in Orchestrator allocating the account dynamically. Specifying both the account and the machine template means the job launches on that very account-machine pair.

Note: Make sure the required runtime licenses to execute the job are allocated to the associated machine template.
Hostname After selecting a machine template, the Hostname option is displayed, allowing you to select the desired workstation/robot session to execute the process.

All available sessions in the active folder are displayed, either unconnected, disconnected, or connected.

Note: Only unattended runtimes can be used to configure the mapping. Make sure the required runtime licenses to execute the job are allocated to the associated machine template.

📘

Hostname selection

  • A warning is displayed upon selecting a hostname that is not active (i.e, with the Unresponsive or Disconnected status). Jobs scheduled to be executed by the inactive session remain in a Pending state until the corresponding connection to Orchestrator is made.
    To acknowledge your selection of the inactive hostname, click Confirm.
    To go back and make another Hostname selection or none (i.e, the first available machine in the template pool gets selected), click Cancel.

  • Configuring the same trigger with the same account-machine mapping, but with the additional hostname selection doubles the number of jobs to be executed.
    For example, say you configured a trigger T1 with the account A1 mapped to the machine template MT1. A number of ten jobs are queued in this configuration.
    Later on, you configure the same trigger T1 with the account A1 mapped to the machine template MT1, but now you also select a hostname H1. The same ten jobs are queued again for this case, as Orchestrator interprets the configuration as new.
  1. On the Arguments tab, provide values for input arguments if your process has any. More details about input and output arguments.
  2. Fill in the Minimum number of items to trigger the first job., Maximum number of pending and running jobs allowed simultaneously., Another job is triggered for each _ new item(s) fields.
Description
Minimum number of items that trigger the first jobThe item-processing job is only started after the targeted queue has at least this number of new items. Deferred queue items are not counted.
Maximum number of pending and running jobs allowed simultaneouslyThe maximum number of allowed pending and running jobs, counted together. For 2 or more jobs allowed simultaneously, the third option needs to be defined as described below.
Another job is triggered for each __ new item(s)The number of new queue items (on top of the number configured for the Minimum number of items that trigger the first job option) to trigger a new job.
  1. From the Timezone drop-down menu, select the time zone according to which the queue trigger gets disabled (see step 13).
  2. From the Non-working days restrictions drop-down menu, select a non-working days calendar if you want your trigger to stop firing on certain non-business days. More details about non-working days.
  3. Turn on the Schedule ending of job execution toggle to select a job termination strategy.

  1. Enable the Schedule automatic trigger disabling toggle, and enter the date and time when the trigger is to be disabled. The time zone selected in step 10 influences when the queue trigger gets disabled.
  2. Turn on the Generate an alert if the job is stuck (in pending or resumed status) toggle, and set the acceptable duration for the job to remain in the pending or resumed status. The minimum configurable duration is one minute. The maximum configurable duration is eleven days. If the job exceeds the configured duration, an "Error" severity alert pop-up informs you about it with the following text:
    "N jobs for #process {process_number} have been pending or resumed for more than X hours and Y minutes.", where:
  • N - is the number of jobs that triggered the alert;
  • {process_number} - the process identifier;
  • X - the configured number of hours the job exceeded while having the pending or resumed status;
    Note: Days are converted to hours.
  • Y - the configured number of minutes the job exceeded while having the pending or resumed status.
  1. Turn on the Generate an alert if the job started and has not completed toggle, and set the acceptable duration for the job to complete. The configurable duration is minimum one minute and maximum eleven days. If the job exceeds the configured duration, an "Error" severity alert pop-up informs you about it with the following text:
    "Job for #process {process_number} has been pending been running for more than X hours and Y minutes.", where:

Managing Non-Working Days


Creating New Calendars

  1. Open the Non-Working Days tab on the Settings page. A list with all the calendars previously defined is displayed, ordered alphabetically.
    The BankHoliday calendar is displayed here, if it exists. This calendar is created when upgrading your Orchestrator to 19.10 if you had non-working days defined in your previous version.
  2. Click Add to create a new calendar and type its name in the blank, highlighted field. The name must be unique, and it may contain a maximum of 150 alphanumeric characters. You can't create calendars with no names or containing only space characters.
  3. Click Save or press Enter on your keyboard to save the new calendar. The calendar is saved and displayed in the list of calendars.
  4. For the selected calendar, define non-working days either manually, or by uploading a .csv file, or a combination of these.
  5. In the Triggers page, when creating a new trigger or editing an existing one, select the desired calendar from the Non-working days restriction drop-down.

📘

Note

When you use non-working days, the trigger time zone must be the same as the tenant time zone (Tenant > Settings > General tab), because calendar restrictions cannot be applied in different time zones. A tenant without an explicitly defined time zone inherits it from the host.

  1. Click Update for the changes to take effect. Every change made to a calendar subsequently propagates to all triggers associated with that calendar.

Manually Selecting Non-Working Days

  1. Click a calendar to select it. The calendar on the right-side of the window is updated accordingly.
  2. On the displayed calendar click the dates on which you want your triggers to stop firing. Click again on a selected date to deselect it.
  3. Click Save to save the selected dates as non-working days.

Uploading .csv Files

Enables you to upload a series of dates into a selected calendar, directly from a .csv file. Please note that the file must be populated beforehand using a predefined format so that the upload operation is successful. The new dates from your uploaded file overwrite any dates already contained in the calendar.

📘

Important!

The .csv file must contain ExcludedDate column header. All the non-working days must be within that column, written in the YYYY-MM-DD, YYYY/MM/DD or YYYY MM DD format.
Expand the Example section below for more information.

  1. On the selected calendar click Upload csv.
  2. Navigate to the desired .csv file, select it and click Open. Orchestrator parses the file to confirm it meets formatting rules (see the example section below).
  3. Click Yes in the confirmation dialog to overwrite the dates already contained in the calendar with the new dates from your uploaded file.
  4. Click Save to save the modified calendar.

OR:

  1. Drag & Drop the desired . file over the selected calendar's top part. Orchestrator parses the file to confirm it meets formatting rules (see the example section below).
  2. Click Yes in the confirmation dialog to overwrite the dates already contained in the calendar with the new dates from your uploaded file.
  3. Click Save to save the modified calendar.

 

Let's say you upload into a calendar the content of the following .csv file. An easy way to create such a file is to populate the data into an excel file and save it as a .csv file:

SaveAsCSV

Or you can download a .csv file with all the pre-filled column headers and customize it to your needs.

Download file

 

Notice that this file contains a predefined column header, ExcludedDate. Enter all your non-working days in that column, using YYYY-MM-DD, YYYY/MM/DD or YYYY MM DD format.
