SIL Scheduler

The SIL Scheduler allows you to run scripts at specific time intervals or at various times using CRON.

Managing SIL™ Scheduler

The SIL™ Scheduler feature enables you to run SIL™ scripts after a valid Jira interval or using a CRON expression.

Starting with version 4.0.0 of Power Scripts™, the jobs are persistent that is they are kept alive towards Jira restarts. You can read about scheduling jobs here: Scheduling routines. This mechanism uses the same scheduling engine, thus the same notes apply.

Each scheduled job has the following properties:

  • Job type - either interval or CRON expression

  • Schedule - valid Jira interval or a CRON expression

  • Script - SIL Script that will run using the schedule that you define

  • Arguments - job arguments

  • Run script as - if specified, the script will run as if by this user

  • Does this job repeat? - if you use a Jira interval, you can define whether the job should repeat at the specified interval


To schedule a CRON job, change the type to "CRON" and enter a valid schedule (Quarts CRON expression).

The Quarts Cron expressions also considers the seconds, unlike the traditional Cron expressions:

SIL Scheduler: Sec Min Hour Day Month Day of Week

Traditional Cron: Min Hour Day Month Day of Week




After saving the added job, a new entry is added to the table on the Administration page.

No user provided

Please keep in mind that if no value is provided in the Run this script as textfield, the script will run with no user. Therefore, the script will NOT have the required permissions to interact with Jira tickets, unless the project allows for anonymous access or the script explicitly calls out the user to use within in the script using the runAs routine.

It is highly recommended to provide a user to the scheduled job when interacting with Jira tickets.
