Quartz has its own cluster mode with each instance of eXo Platform server as a member of Quartz load balancing and failover group.

In case of a single node instance orgquartzjobStoreisClustered is marked as false. Load-balancing occurs automatically with each node of the cluster firing jobs as. Job may be submitted and scheduled by any node in the cluster.

Using Quartz Scheduler in a cluster In a previous post I described how to use Quartz scheduler for scheduling. When eXo Platform runs in the cluster mode it is important to prevent the duplicated execution of jobs. 60000 checks-in with the other instances of the cluster default 15000 As you have seen I made the orgquartzjobStoreisClustered to be true.

Features include load-balancing and job fail-over if the JobDetails request recovery flag is. I have made all the tables in the db. That is 17 duplicates.

When the Quartz Scheduler is started it calls the schedulerStarted method on the JobStore which as the name implies tells the JobStore that the Scheduler has been started. The application will have a Rest API that allows clients to schedule Emails at a later. In this post I describe the configuration changes required for using Quartz Scheduler with Scheduling.

Though its also possible to do clustering with Terracotta without a persistent job store I recommend against it for most projects since job execution history is very useful to ongoing operations and troubleshooting and database-clustering performs.
