Chapter 4 Creating and Administering Clusters 61
Setting Passwords and Scratch Storage
You can create several different types of passwords for the Apple Qmaster distributed
processing system. All these passwords are optional; you can use the system without
creating them.
 Cluster administrator password: A password required for modifying a cluster in
Apple Qadministrator, and for modifying the status of the cluster’s batches in the
Batch Monitor. See “Setting Cluster Administrator and User Passwords,” next.
 Cluster user password: A password that client users will need in order to submit
batches to a cluster and to modify the status of those batches in the Batch Monitor.
See “Setting Cluster Administrator and User Passwords,” next.
 Service password: A password required for an administrator to add a specific service
node or cluster controller to a cluster. See “Setting a Service Password for Including a
Computer in a Cluster” on page 62.
You can also change the default scratch storage location for a cluster, or for each computer
in a cluster. See “Cluster Storage: Setting a Scratch Storage Location” on page 62.
Setting Cluster Administrator and User Passwords
You can create cluster passwords while creating a new cluster, as described in “Creating
Clusters with Apple Qadministrator” on page 50. However, once the cluster is created,
you can still add or change passwords, using the same settings in Apple Qadministrator.
To create or change cluster passwords:
1 In Apple Qadministrator, select the cluster from the Cluster list.
2 Click Security.
3 Select and enter or change the passwords you want.
4 Click Apply Changes.
Note: Cluster administrator and cluster user passwords can be stored in a user’s keychain.
