When you create a software configuration and assign it to user accounts, when you change a software configuration that you assigned to user accounts, or assign or change an IT policy, the BlackBerry® Administration Service creates jobs to deliver the resulting objects or settings to BlackBerry devices. A job consists of multiple tasks. Each task delivers a specific object or setting to a BlackBerry device, for example, upgrading BlackBerry® Device Software, installing or removing a BlackBerry Java® Application, or sending updated IT policy settings or application settings.

You can change the default settings for a job to control how the BlackBerry Administration Service processes jobs. If you change the default settings for a job, your organization's environment might experience a performance impact.

1. In the BlackBerry Administration Service, on the Devices menu, expand Deployment jobs.
2. Click Specify job schedule settings.
3. Click Edit job schedule settings.
4. In the Default delay for each job section, in the Default delay field, type the number of minutes that the BlackBerry Administration Service waits before it creates and processes a job. The default value is 15 minutes.
5. In the General section, in the Mark job as failed field, type the number of days that the BlackBerry Administration Service waits before it defines a job that was not delivered to BlackBerry devices as failed. The default value is 30 days.
6. In the Purge jobs field, type the number of days that the BlackBerry Administration Service waits before it deletes a failed job or a completed job. The default value is 7 days.
