Scheduling the Garbage Collector
Ordinarily, the Garbage Collector is automatically scheduled. However, there may be scenarios will the job fails to schedule properly.
If deleting a CO generates a "No job of type CoreJob.GarbageCollector available" error, manually reschedule the GarbageCollector job via COmanage CO > Configuration > CO Settings > Garbage Collection > Schedule Job. If a View Job button is present instead, the Job has already been scheduled.
