Use the Phantom Maintenance screen to set system-level parameters for improving system performance by controlling the number of phantoms that can be running at any given point in time.
In addition to controlling the number of running phantoms, you can also control the number of queued phantoms. When the system reaches user or system-level thresholds, the system queues the phantoms until resources are free.
Use the
Use the Maximum Number of Running Phantoms option in User Maintenance to limit the number of phantoms that run at one time. Limiting the number of phantoms allows the system to run more efficiently.
Note: You can set phantom maintenance parameters at the user and system levels. When user-level settings do not exist, the system uses the system-level settings.
