A class is a group of jobs. Each job must be a member of one and only one class. You can use classes to apply different global management behaviors to each job in a class. A job gets its default class from the properties of its project. You can also manually choose a different class for a job when you launch it from the
page.Classes have properties to manage the following activities:
Use the Classes panel to add, edit, and delete classes. To view the panel, select
. The system displays a list of classes. Select a class to edit its properties.The Access property of a class controls which users can view or change the class, based on the access group you assign.
The system checks for jobs to delete at an interval defined by the Purge Check Time system setting, which defaults to 15 minutes.
When a purge job runs, the system archives the job and deletes data according to settings in the class.
* The system deletes jobs when either the Days or Count values are exceeded. For example, if you have Count set to 10 and Days set to 2, and there are 8 jobs, but 3 are more than 2 days old, those three jobs would be deleted. Similarly, if you had 12 jobs, all less than 2 days old, the two oldest jobs would be deleted.
When a purge job runs, the system archives the job and deletes data according to settings in the class.
These properties launch projects as chains.
