3.9.14.2.2. Tasks Handling Control

  • cuba.schedulingActive application property should be set to true to enable tasks processing. You can do it either in the Administration > Application Properties screen, or through the app-core.cuba:type=Scheduling JMX bean (see its Active attribute).

  • All changes to tasks made via system screens take effect immediately for all servers in the cluster.

  • The removeExecutionHistory() method of the app-core.cuba:type=Scheduling JMX bean can be used to remove old execution history. The method has two parameters:

    • age – the time (in hours) elapsed after the task execution.

    • maxPeriod – the maximum Period (in hours) for tasks that should have their execution history removed. This enables removing the history for frequently run tasks only, while keeping the history for tasks executed once a day.

      The method can be invoked automatically. Create a new task with the following parameters:

      • Bean name – cuba_SchedulingMBean

      • Method name – removeExecutionHistory(String age, String maxPeriod)

      • Method parameters – for example, age = 72, maxPeriod = 12.
