Scheduler configuration
Liferay Portal provides built-in integration with the Quartz scheduler. Many of the
Liferay features use a scheduler. Depending upon the feature and its configuration,
the scheduled jobs are executed in the background. These background jobs run on
the same Liferay Portal servers. Hence, these jobs will use the Portal server resources.
Scheduled jobs are executed for all the features irrespective of whether they are used
or not. They may finish quickly but will consume some of the system resources.
Hence, it is advisable to disable schedulers associated with unused features. The
following built-in features use schedulers in Liferay Portal:
• The Calendar portlet
• LDAP integration
• The Web Content portlet
• The Message Board portlet
• The Blogs portlet
• The Media Library portlet
• The Announcement portlet
The Calendar portlet
Liferay's Calendar portlet uses a scheduler to send reminders for events. If the
Calendar portlet or event reminder feature is not used, it is recommended to disable
the scheduler job created for the Calendar portlet. To disable the scheduler used in the
Calendar portlet, we need to add the following property to
portal-ext.properties
:
calendar.event.check.interval=-1
