Maintenance Services

System maintenance and cleanup services are scheduled and tracked through a calendar and task enablement/prioritization menu. Services such as deletion of temporary files and profile purging are scheduled for one-time immediate action or scheduled on a recurring basis. Users can configure the schedule to run the maintenance bundle at a specific time of day with a maximum of daily frequency and minimum of monthly interval.

Scheduling Maintenance Services

Specify a schedule for Maintenance Services by clicking on the + icon located on the right side of the Schedule bar. Note that any schedules in place will be overwritten by new schedules. Schedule options include One Time Immediate or Recurring.

One Time Maintenance Schedule

Once One Time Maintenance Schedule is selected, tasks can be ordered and enabled or disabled.

Recurring Maintenance Schedule

Choose your Schedule allows an Admin to select date and time of repeating Maintenance Services.

Custom Schedule requires entry of a Crontab Expression where a string of six or seven fields describe schedule details separated by a space (e.g., "0 15 10 15 *?$"). Save the Crontab expression to initialize a new schedule.
