Turn cluster controller services on or off
You can easily turn a specific computer’s cluster controller services on or off.
Turn on cluster controller services
1 In Compressor, choose Apple Qmaster > Share This Computer.
2 Select the “Share this computer” checkbox and do one of the following:
•
To create an “instant” cluster with unmanaged services: Select “as QuickCluster with services.”
•
To build a cluster in Apple Qadministrator: Select “as Services and cluster controller.”
For more information, see
Create and modify a cluster on page 258 and Enable managed and
unmanaged services on page 228.
3 In the Services area, select Rendering or Compressor, or both.
4 Click OK.
The cluster is enabled, making this computer a cluster controller.
Turn off cluster controller services
1 In Compressor, choose Apple Qmaster > Share This Computer.
2 Deselect the “Share this computer” checkbox and click OK.
Important: If you’re 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.
Note: You can instead turn off the controller and just make the node a service node. To do this,
select “as Services only” in the “Share this computer” section.
Set a service password for including a computer in a cluster
If you want to control who is able to include a specific service node or cluster controller in a
cluster, you can create a password called a service password for the computer.
•
If you set up a QuickCluster: Other users will be required to enter this password before
submitting requests to this computer.
•
If you set up a cluster to use with Apple Qadministrator: An administrator will be required to
enter this password before adding this computer to a cluster.
•
If you configure the computer as both a cluster controller and a service node: One password is
used for both users and administrators.
Note: A service password can be stored in a user’s keychain.
Set or change a service password
1 On the computer designated as the service node or cluster controller, open Compressor and
choose Apple Qmaster > Share This Computer.
2 Do one of the following:
•
To require a password: Select Require password.
•
To change an existing password: Click Change Password.
