Assets Server Scheduled plug-ins - configuration settings

Note: The use of internal plug-ins such as Scheduled plug-ins has been deprecated in Assets Server 6.73. These plug-ins should instead be implemented as an API, Webhook, or via WoodWing Connect.

The configuration file of a Scheduled plug-in is named 'schedule.config.xml' and consists of the following structure:

• General information is specified between the <info> </info> tags.

• Generic settings are specified between the <schedule> </schedule> tags

• Specific settings are specified between the <config> </config> tags

<?xml version="1.0" encoding="UTF-8"?>
<plugin>
    <info>
        
    </info>

    <schedule>
        
    </schedule>

    <config>
        
    </config>
</plugin>

This article describes the generic settings.

For information about the general information settings and the specific plug-in settings, see Assets Server plug-in configuration files.

The Generic schedule settings

The generic schedule settings control when the plug-in should be executed.

<schedule>
	<active>false</active>
		
	<triggers>
		<!-- Fire every 5 minutes -->
		<cronTrigger>0 0/1 * * * ?</cronTrigger>
	</triggers>
		
	<runAgainWhenJobHasMoreWork>true</runAgainWhenJobHasMoreWork>
		
	<allowParallelExecution>false</allowParallelExecution>
</schedule>

The settings can be divided into basic settings and advanced settings.

Basic settings

• active (Required) Controls whether the schedule should be active or not. Possible values:
• true. (Default) Makes the triggers (see below) active.
• false. Disables the triggers, Executing the plug-in can still be done manually through the plug-ins page of the Management Console.

• triggers (Optional) One or multiple cronTrigger tags which define how the plug-in is scheduled. The cron trigger format is based on Unix cron with the addition of the seconds field. It has the following format:

Seconds Minutes Hours Day-of-month Month Day-of-week [Year]

Note: Assets Server uses quartz as its scheduling engine. For details, see the Cron Trigger Tutorial on quartz-scheduler.org.

<!-- Fire at 23pm every day -->
<cronTrigger>0 0 23 * * ?</cronTrigger>

<!-- Fire every 15 minutes -->
<cronTrigger>schedule2 = 0 0/15 * * * ?</cronTrigger>

<!-- Fire every 5 minutes -->
<cronTrigger>schedule3 = 0 0/5 * * * ?</cronTrigger>

<!-- Fire every 5 minutes at 2 past, 7 past, etc... -->
<cronTrigger>schedule4 = 0 2/5 * * * ?</cronTrigger>

<!-- Fire every minute -->
<cronTrigger>schedule5 = 0 * * * * ?</cronTrigger>

<!-- Fire every 2 hours between 8 AM and 8 PM on business days -->
<cronTrigger>schedule5 = 0 0 8,10,12,14,16,18,20 * * 1,2,3,4,5</cronTrigger>

Advanced settings

Note: The advanced settings are in most cases correctly defined by the plug-in developer; changing them could cause the plug-in to malfunction.

• runAgainWhenJobHasMoreWork (Optional) Controls if the plug-in only runs once or if it runs again if it has more work. Possible values:
• true (default) Run the plug-in again if it has more work.
• false. Run the plug-in only when it is scheduled.

Note: A plug-in can notify the scheduler that it has more work by creating an empty file without any extension in its 'plugin' folder with the name: has-more-work.

• allowParallelExecution (Optional) Controls if the plug-in will be executed in parallel or not. Possible values:
• true. Execute the plug-in in parallel when a trigger fires while the plug-in is already running.
• false (default) Do not execute the plug-in in parallel; any trigger that is fired while the plug-in is running is delayed.
