The Scheduler service provides a generic job scheduling service for System Manager and Avaya Aura® applications. The Scheduler service provides an interface to run a job on demand or on a periodic basis. You can schedule a job to generate an output immediately or set the frequency of the task execution to run on a periodic basis. You can modify the frequency for a periodic job schedule any time. After you define a task or a job, System Manager creates instances of the task, monitors the execution of the task, and updates the status of the task.

Scheduled jobs can be of three types:

• System scheduled: The job that the system executes on a periodic basis for the system to operate normally. The system adds these jobs at start-up and supports all frequencies other than one time. Scheduled jobs run asynchronously in the background. As an administrator, you cannot add or delete system-scheduled jobs. You can only disable or enable the jobs to stop temporarily.

• Admin scheduled: The job that the administrator schedules for administering the application. The administrator can use various navigation paths to schedule jobs such as bulk import and directory synchronization. The system lists the jobs in the scheduler as admin scheduled jobs.

• On-demand: The administrator can schedule on-demand jobs from the list of existing jobs.

You can perform the following operations using the Scheduler page on System Manager Web Console:

• View the pending and completed scheduled jobs.

• Modify a job scheduled by an administrator or an on-demand job.

• Delete a scheduled job.

• Schedule an on-demand job.

• Stop a running job.

• Enable or disable a job.

• Search a scheduled job.

By default, the following jobs are in Enabled state after System Manager is installed.

• LogPurgeRule

• ClrdAlarmPurgeRule

• AgedAlarmPurgeRule

For a better system performance, ensure that these jobs remain in an Enabled state.
