To schedule service availability
1 In the Advanced Service Settings area of the Advanced pane within the Apple Qmaster
preferences pane, click Set.
The work schedule dialog appears.
2 To constrain the availability of the services, choose one of the options from the pop-up
menu next to a particular day of the week. See Scheduling Service Availability for details.
3 Enter any constraining time periods in the appropriate start time and end time fields.
Note: You must enter valid days and times. The time cannot overlap into the next day in
one entry. There must be two entries when the range ends after 12 a.m. For more
information, see Setting Availability from Sunday Night to Monday Morning.
4 Click OK to save the settings and close the dialog.
5 Click OK to apply the changes to this computer.
Important: If you are making changes to existing settings and this computer is already
providing processing services, clicking OK immediately resets this computer’s services. If
this computer is also the cluster controller, any current jobs are terminated.
Setting Availability from Sunday Night to Monday Morning
You must enter valid days and times. The time cannot overlap into the next day in one
entry. There must be two entries when the range ends after 12 a.m.
For example, to set the service availability from 6 p.m. on Sunday to 8 a.m. on Monday,

Using Cluster Storage
By default, the Apple Qmaster distributed processing system saves temporary process
files in the /var/spool/qmaster/ directory on the cluster controller. You can also choose
any other location on a local disk for this scratch storage. Computers in the cluster will
access this location as needed.
Adjusting Cluster Storage Settings
Follow the steps below to change scratch storage settings for a cluster.
To change cluster storage settings
1 On the cluster controller, open Compressor and choose Apple Qmaster > Share This
Computer.
2 Click Advanced to open the Advanced pane.
